was just wondering if a busa engine will fit on a 1000 frame if so what all do u have to do to make it work ( man that could be a hell of a sleeper bike)

Na, a 600 frame would be the sleeper

Who cares about 600 frame in this post! If you don't know don't reply to the Q! :nono

What year 1000 frame are you asking about for this project?

Who cares about 600 frame in this post! If you don't know don't reply to the Q! :nonoWell sorry for offending YOU as I was not rambling on about using a 600 instead. Next time I won't bother, and I'll save myself the trouble.

600, 750, and 1000 frames are pretty much all the same except for motor mount locations. The busa motor will fit in the frame but with drastic modifications. So drastic that you would not be able to hide it. Lee Shierts put a busa motor in one just to prove it could be done, but the frame was all chopped up in order to make it fit...but it fit.

I put, a 1000 in my SRAD, anything is possible, I was considering a busa motor before the 1000 motor came up, I should imagine just as I made the mounts for the 1k, it would be the same for the 1300, though it does have a longer stroke and its wider, accross the head, and the 1000 motor, I really had to shoe horn in the frame.
the bottom line is anything is possible, but having the tools to do the job helps,

must be loike riding a lighting bolt.

lol might be like ridein a busa

The Busa 99-06 175hp engine and tranny are 74lbs more than a 05-07 185hp 1k cc powertrain and 62lbs more than 01-04 164hp 1k cc powertrain.. You would be far better off getting a liter power-plant....Also>>
Fuc a Busa!!.. They're 99.9% hype.. Any 1000(except a pre 04 R1)will tear a Busa a new one up to 180mph... Which is the only area the Busa leads the pack is the sub to 200mph+ zone because of it's body shape and very low CD. Other than the 200mph+ zone which you're only gonna see on the salt flats or Texas mile where the Busa is boss, it gets owned by any liter bike. I've killed so many Busa's on my GSXR 1000's if I had a $5 spot every time I wouldn't be typing this, my butler would.
My 06' K6 makes 185hp@365lbs vs. a 99-07' Busa making 175hp@473lbs or the 08'+ Busa making 194hp@484lbs .... Which you can ad 10%+ to all models seeing the factory claimed weight is BS....The real dry weights via CycleWorld are 412lbs, 534lbs and 567lbs..
The Busa is more myth than fact..... Unless you're going to build up the engine for turbo or big bore application.
Yes you can dump $20,000+ into a busa turbo engine build and make 700+hp but, is that really useable?..
Anyways.. Blah, blah, blah you're best bet is to get a GSXR 1000 power plant,,,

Not worth it, but it would be pretty crazy

:wtf

are you for real? Your comparing apples to oranges. There is alot more you can do to a busa than a 1000. And i haven't seen too many 1000's that can hang with a busa up to 180. Not really sure who you are racing. Stock for stock same weighted riders and that busa will leave that 1000 like nobodies business.

yeah straight line performance its busa all the way... you can apply a lot more throttle off the line without the front lifting on a busa, Ive raced against lots of 1k's that dont keep up in a straight line.

i have seen a busa engine in an SRAD frame, it does work with ALOT of work, but is possible and rideable !

it will be pretty good , and the power it mights be more than the stock ( factory ) engine , but it's not worth it , cuz i guess it's going to cost you allot , and in that cost you could modifie your stock engine and it will be like hell , pistons , cams , and small turbo kit , and u'll fly !

Thanks

Same weighted riders if they both weigh 350lbs. :)
stock for stock a 05 and newer gsxr 1000 owns a busa in the 1/4. We can argue about that another day though. :hammer

For high hp turbo applications and big motors their is more/better stuff available for the busa.
It is posible, but is alot of work. I belive macintosh machine and lees performance charge around $4,000 to modify a 1000 frame to work with a busa motor.
The head is too wide for the frame requireing you to cut out the inside of the frame and weld plates in to brace it. Mounts need to be welded to the frame to get the head to bolt up. The back motor mounts do not line up so they will need to be cut off and new mounts need to be made. the busa engine is too long and where the clutch cover goes the frame needs to be ground down alot. The busa sprocket cover needs to be modified to work in the 1000 frame because it is too big.
I have thought about doing it because I was having problems keeping my 1000 engines together with alot of boost. (over 20 psi) Now I think I got it down pretty good and my engines are lasting now so I will be sticking with 1000 engines.

Ok I will not be held accountable for how much BS is in what im about to say, because its a repeat, and i dont know how much truth there is to it. It may be something to check around for though. I was talking to a guy that was riding a sick looking 06 1k when i asked him what all was done to it he said mostly performance and motor mods, such as bored to 1297cc(dont even know if its possible, you can check to see if it is) cams pistons and some other stuff. he claimed that it was still the original 1k block just bored....i dont know if you can bore one out that much, but overall if there is any truth it would deffinately be an interesting build. The bike looked like a regular 1k with some nice little additions. Maybe some of the experts on this site can tell you if this is possible or not.

1242ccs biggest i've seen. Bored 5mil over and stroked 6 mil. But I do believe that there is a 6x6, but not stock cylinders, but not 100% on that. I know the 5x6 is stock cylinders.

:burnout

I am building a 1k/busa right now an i am sorry but i have to disagree with whom ever said you have to chop up the frame to get the motor in place.

YOU DO NOT!!!!!!

All you need is a lil time and patience and an angle grinder and a tape measure.

you do not have to chop anything but you have to shave down mount brackets on the busa motor and shave a few milimeters away on the inside of the 1k chasis not much though!

the front busa mounts match up problem free as does the upper and lower
rear mounts you may have to shave down the inside of the frames rear mount brackets.

all this takes about 10 minutes to do!

be sure to use eye and full face protection when shaving any area
because the little shards of metal are quite hot!!!! i useed a bandana
and my hjc backup helmet and off you go! Safety!!

Note: the 1k gauge clusters cant be used nor the computer or the wiring harness. and you will have to reroute the 1000s throttle cable because the busas throttle cable runs along the throttle hand side Not the clutch hand side like on the 1000.

toughest part is having to raise and lower the motor in place each time you shave it to make sure its slarting to slide in the cavity correctly.

so be patient. it will work and you dont have to kill your self to do it.

Note: the busa header and exhaust has to be used
Note: the 1000 front sprocket can be used (16) tooth!
Note: the busa battery should be used

fire it up and you will be good to go!

be very easy on the throttle because a busa has way more torque!

I drag race only so for the street id get a little longer swing arm if i were
you guys.

SEE no chopping occurs at all! but lee and i know him personally probably had to with a 98 srad frame!

ill believe it when pictures are posted.....

Sooo.... I'm guessing this will work in a 2002 GSXR 750 frame???

I just want to knoe for future reference...........

I raced a guy on a busa last year. He was stretched and lowered, full ti force system, pcIII, don't know what else cause he won't say and dyno tuned by the best in our area. I was on my k7 1k with slip on, k&n, pcIII, stock height and stock everything else. We are pretty close to the same weight and both have moderate drag racing experience. We raced from about 25 in 1st gear and I pulled him easily all the way to 170-175. Busa's make a lot of torque but gixxer's pull pretty hard on top.

Racing a busa on the street with limited traction and racing one on the track that hooking is a different story busas usually are out front at the track by the 330 . roll ons dont matter really for anything.

i

ill believe it when pictures are posted.....

its not for you nor anyone else to believe and weather you do or not
i just posted the information because thats what i am doing with mine!

i

Yes i am very aware of this, but he was talking about racing to 180. How many bikes are capable of hitting 180 in the 1/4? Like I said, Busa's make good torque, that is why they are good at the track. But with a good rider on a 1k, beating a busa at the track is possible. I've done it, have video to prove it. I'm by no means an expert drag racer, just saying it is very possible.

From the July 2008 Cycle World:
60mph to 180mph
Hayabusa 15.67 sec
GSX-R 1000 15.73 sec
ZX-14 17.15 sec
CBR1000RR 18.14 sec
ZX-10 14.37 sec
YZF-R1 18.21 sec
1098R 18.25 sec
MV 1078RR 15.14 sec

As a side note, from 60mph to 150mph
GSX-R 1000 7.28 sec
Hayabusa 7.60 sec


It will come down to the rider. I don't have figures for the old 'Busa, but I suspect it would be significantly slower than the new one.

Yeah I know...but it's winter here...

ok guys i took 2004 plastics and modified them to fit my 02 1k frame for a new look and also installed my 02 busa motor in my 02 1k frame!

For the non believers! Now please note that this set up will be used for drag strip grudge races only and not for the street! i have installed an air shifter.

i now use the busa wiring harness (cant use the 1k)

Notice the accellerator cables are located on the right and not the left as with the 02 1k i also had to change out the clutch lever from cable of the 1k to hydraulic as the busa uses.

I have a new Murray Sidewinder exhaust (it makes more hp than brocks and caust 500+ dollars cheaper.

i also have ordered aa cut radiator (stock but cut down way smaller to be fitted in the subframe under the tail section)

its almost ready to crank.

sorry about the poor Quality camera phone pics!

Nice!! I'm impressed, good job man!

I've just always heard this was basically impossible.... w/o serious frame mods (more serious than what you've done there, although what you did obviously took some work)

either way 1k vrs busa if you are the guy on the 1k and it is a straight line, you WILL have to be 110% on your damn game to beat a busa from a dead stop, esspecially running in street trim IE no lowering no straps no extentions IE the stock wheele base, i run stock wheel base ver the same on both 1st gen and a budy who now has a 2nd gen, the 1st gen is possible to beat its hard and your going to lose at the strip most of the time, due to they have the advantage, its a come from behind win when you do it, they can put more of thier power to the ground due to the longer stock wheel base and they have more weight out front, ive run a 2nd gen busa from a rolling 2nd gear and a rolling 3rd gear and holy crikey bat man he had a pipe though, but my 03 1k is not near stocke either, in 2nd if i worked hard to keep the wheel down i could almost match him for the most part he kept creeping though, in 3rd i would crush him and run away till i was shifting into 5th when he would come back by me like a mad man in the middle of 5th it evened out and in 6th still even till we got up around 160 then he started to slowly pull away. at the drag strip i dont think i have a chance and thats even if i strap and lower my bike and he would stay stock height, but i already know hes going to strap and lower, so my only chance would lie in more length.

the main thing though that will absolutely make the difference is rider skill, more than anything the rider can take crap and beat the best.

Some of this is true and some not true. i drag race in the AMA and grudge race
for money and if you have a long 1k and long busa 10 or more inches sure you have a chance to win if you are the better of the two riders but if you have 2 equal riders of weight and skill the busa wins from 2nd gear on.

Roll ons dont mean anything at all and dont prove a thing Real drag racers already know this!

if riders are equal weights and skill the busa wins no matter the gen! ive beat a few busas and ive had a few walk by me on the big end just before i got to the traps! the busas torque and top speed is way above any generation of 1ks top end in a straight line. but doing roll ons on the streets doesnt prove a thing for you except you twisted the throttle before whom ever you were rolling on with did! and theres no way to prove you both twisted at the same exact instant!

Go to your local track and then you will see that not too many skillfull busa riders will lose to any skill full riders on 1ks.

1ks are no slouch but busas are the winners on the track most times!

Now if you get into spray and big motors then thats something different!

ive seen an all motor 1k beat the breaks off a turbo busa in the 1/4 or the 1/8th but wins like that are few and far between and take "great" not good but great riders like shine or richard gadson.

hell yeah way to go man

Project complete heres a quick Bio of the bike!


02 busa motor
02 1k frame
04 fairings slash cut
14 inch over Adams performance fixed end swing arm
mps air shifter kit!
mps nitrous spray bar and 60 shot nitrous
Clutch mod
Muzzy Sidewinder exhaust system
43-16 gearing
Shinko U-soft on the rear!
miniature radiator used and mounter in the tail section/with the fan!
oil cooler removed i`m using the oil cooler by pass kit from Snitz racing!

Since i will be using it predominantly for grudge racing
i cant share my times but i can say that when comparing them against my
1000`s times i greatly improved in every incriment! and i am very
happy with its performance! heres a pic.

i see some guys dont understand the point.rooling from the 25 hit is uselessthe guy that hits first gets a 1/2 sec head start.id go into it more but i dought they would even understand what i was telling them.the busa weighs ove 130# more than a 1000.

so the question i want to know is what does the gsxr 1000 hybrid wheights?id consider to do this swap because the bottom end is stronger (nos) and i can get alot of cc from the hayabusa engine.

Busa's come geared way taller than liter bikes from the factory. You gear them equal....plus add in the busa's torque advantage, and they're fast as hell everywhere...roll-ons, street, strip etc. And because of the torque advantage they're easier to launch and ride faster :punk

I have a question will a busa motor fit in and 04-05 750 frame

Final finished product! my 1441 cc hybrid weighs 320 lbs 60 shot of progressive nitrous and is Tuned with maps to run on Spray or motor!

has a 70 inch wheel base! built the motor completely inside out my self!
also customized the frame to accomodate the motor.

Absolutey no cutting to the frame was done!

Has a 2 dial Shnitz racing progressive nitrous controller and mps electric shifter. lots of extras!

Its a very doable project if you have the time tools and money

it is not a street legal bike any more!

Thats a beauty, nice job building it! I bet its a handful & more.

Great job man. Thanks for sharing. Obviously this project is both doable and well worth the work.

By the way, what would you say is the weight difference in the Busa versus the 1K????? Weight loss nets ET drop all day long and sometimes its a lot cheaper to drop the weight than to increase horsepower. This is an excellent example of that formula. :cheers

What is the bracket that I have circled in this pic? Also, are you running a busa radiator or a 1k radiator?

What is the bracket that I have circled in this pic? Also, are you running a busa radiator or a 1k radiator?


At the very begining i thought that i would need the bracket because hybrid racing uses the same type but after testing the bike i was confident that i could remove them both!

they weight too much about 3lbs a piece. i admit that in the pic the whole set up llooks hideous because that was basically a rough draft of what i wanted to do. so i threw on a stock exhaust and some old plastics .

just incase i went down during testing. i didnt want to mess up my good plastics. or my sidewinder exhaust.


I have busa hydraulic clutch system busa gauges busa radiator cut in half lower weight!

still using the 1k regulator and fuel pump and 1k airbox but busa throttlebodiesand busa power commander, 08 busa crank with 07 stock rods
1397 cylinder and pistons and ported and polished carpenter head and cams
with adjustible sprockets. 60 shot of spray (progressive) and an mps airshifter.

14 over adams swing arm but i experienced traction issues so i replaced stock
shock with a penske fully adjustible shock now at 14 over the bike hooks like a short wheel base bike and still wheelies 11 oclock if i stay in the throttle.

i have not used the spray yet because with 1441 ccs i really have no need!

i `ll be at rockingham dragway on march 6-7 for the all bike grudge fest.

I can no longer ride it on the streets. an im glad. its real lite and very strong.
and was worth the build.

its in my avatar .

As A 'Busa owner I have to agree that what you say is, unfortunately, true. I've seen big-bore and nitrous 'Busas that didn't quite make 200mph at Maxton (I'm sure its the same at Texas) and the best I could get out of a stock '03 was 173. Maybe if I could have squeezed my gut out of the way, a bit more but not any of the really high numbers we have all heard about.
Want a sleeper? Go with a turbo with a full exhaust

The Busa 99-06 175hp engine and tranny are 74lbs more than a 05-07 185hp 1k cc powertrain and 62lbs more than 01-04 164hp 1k cc powertrain.. You would be far better off getting a liter power-plant....Also>>
Fuc a Busa!!.. They're 99.9% hype.. Any 1000(except a pre 04 R1)will tear a Busa a new one up to 180mph... Which is the only area the Busa leads the pack is the sub to 200mph+ zone because of it's body shape and very low CD. Other than the 200mph+ zone which you're only gonna see on the salt flats or Texas mile where the Busa is boss, it gets owned by any liter bike. I've killed so many Busa's on my GSXR 1000's if I had a $5 spot every time I wouldn't be typing this, my butler would.
My 06' K6 makes 185hp@365lbs vs. a 99-07' Busa making 175hp@473lbs or the 08'+ Busa making 194hp@484lbs .... Which you can ad 10%+ to all models seeing the factory claimed weight is BS....The real dry weights via CycleWorld are 412lbs, 534lbs and 567lbs..
The Busa is more myth than fact..... Unless you're going to build up the engine for turbo or big bore application.
Yes you can dump $20,000+ into a busa turbo engine build and make 700+hp but, is that really useable?..
Anyways.. Blah, blah, blah you're best bet is to get a GSXR 1000 power plant,,,

The busa's advantage is on the dragstrip. Its big torque gives it a big advantage over the liters, thats why guys like this run busa's at the strip.....cause they kick liter ass there :biggrin You notice he built this bike for the drag strip not for roll on racing on the highway?

an up dated photo of the bike as it sits now.

where is the radiator?:)

It wont fit. Any of engine brackets wont match...

Forget it.

Here some pictures : http://picasaweb.google.com/purkuosia/Busa1000#

I tried with gsxr 1000 -01 and gsxr 600 srad -98 frames.

was just wondering if a busa engine will fit on a 1000 frame if so what all do u have to do to make it work ( man that could be a hell of a sleeper bike)

the main thing though that will absolutely make the difference is rider skill, more than anything the rider can take crap and beat the best.

Could agree more..I had a K7 1000 and a gen 1 busa previous to that, both made 163RWHP and the GSXR is much more vivid acceleration wise when its on the boil, it also FELT faster and I dare say, if measured it probably was faster acceleration wise.

However, I sorely missed the Busa lump Vs the 1000 straightaway after changing(which is one reason why im now riding another Busa...), Litre lumps feel so weak low down Vs the grunt of the 1300 and away from a drag strip or a road race, thats what makes Busa's (and torquey V twins) feel so nice to ride..My GSXR made 81ft lb of torque at 10,700RPM...my Busa made that at 4,000RPM and made 98ft lb at 7,700RPM..peak HP doesnt necessarily make for a "nicer" bike, its how its made.

IMHO, while I admire the guts and engineering that goes into engine swaps like this, I think its somewhat pointless, if you want a 1300 lump buy the 1300 but fair play anyway.

To the poster who only got 173MPH out of his Busa, you need to practice your launch and get your body position sorted but its not uncommon, my mate could "only" wring 162MPH out of his Blackbird(measured at a proper top speed event on RAF Woodbridge ,not a speedo reading) while I got 176MPH straightaway..Not many people manage to break into the 10's at the first few attempts either but thats another subject.

Trap speeds are relative to whp, not the launch. I'm not picking on you as I'm sure that you already know this. Don't get me wrong, every little bit counts, but it's not by much when it comes to trap speeds. :cheers

No, im with you mate, i wasnt clear enough there, if you only have 1.5 miles to get up to V Max, getting the best terminal speed in that distance can be aided by getting that good start..if your down a second and 10MPH over the quarter mile it all adds up...and a good Vs poor "tucked"position can be worth several MPH

Not that Im that interested in flat out speed, my Busa saw more action on track days than at flyer/qtr mile events..

busa engine 99-07 shud be similar.. so are the engine mountings n circuitory position the same with 04 gixxer 1000...? is there any mod to do or just "plug n play"...?

The Busa head wont fit w/o slight modification of the 04 1k main frame

busa head 17 inches across the 1ks is 15 and a half!

gonna have to grind down some aluminum.

i have an 04 GSXR 1K and was thinkin about puttin a busa motor in it, topndrnna what all do you need parts wise besides the motor/ecu/wiring harness? and also does the motor get any hotter then normal on your bike?

you said you used the gsxr 1000 fuel pump and regulator. did you jump the fuel level sensor to the busa cluster or just say f-it and not have a fuel gauge that works. just want to know cause im planning this for a street ridable bike.

I love these motor swap threads:
I think it would be better to remove the 20mm out of the mounting bracket on the frame. I did a Srad 1000 motor swap. It was dam tight so I imagine youll have a bit of fabricating to get it to fit. My mountings were re fabricated and welded back into position. If you move the holes in the side of the frame it will make life a little easier when it comes to fitting the engine.
The pics are only to show how the mountings were done and the frame without transission plates. In pic3 it was easier to cut the side stand bracket in half and reweld the removed piece no need to cut the sump to make it fit.
Enjoying this thread.:cheers

I just need to know how the fuel pump from the 1k got wired to the hayabusa wiring harness?

Just from what I see there, that looks like a nice clean install, nice work :)

facepalm this thread is retarded

take a motor for going strait and put it in a bike for turning and then make it go strait. Up next check out my busa with off road suspension project. I will tear the shit out of those 250 lb 250 2-strokes

And for all those busa haters the dam bike is over built to handle more HP then stock this is why it is so heavy and why it is so loved becuase of the ease of modifcation.

Noone can keep up with me on interstate I have passed state troopers at 220mph

:facepalm
