Cam upgrade/interchangeability????

in a 2004 GSXR 600, I know that people swap their cams out with those from a 750 and 1000. Which cam from which bike replaces the 600 cams? What kind of increase should be expected?

Re: Cam upgrade/interchangeability????

I am running 02 gsxr1000 cams in my 01 gsxr750 race bike. On the dyno i had picked up 15 to 20 horses. But the bad news is in order to get this power gain you must use adjustable cam shaft gears and 1 mill off the head with a race head gasket. I just got my bike back for Redline Perf and they have my bike pushing around 142 horses at the rear wheel. That also includes 4 hours on the dyno playing with the maping on the power commander and the adjustments on the cam gears. I am looking at having the head work after race season is over and maybe going with 318 kit.

Re: Cam upgrade/interchangeability????

I talked to a guy yesterday who has been racing mini-sprints for 30 years. He has been using the 600 motors in his cars, and I'm going to stop by and talk with him in the next couple of days. He did mention that he is running 1000 cams in the motor (didn't say whether it was intake or exhaust, or both.) I'll post up what info I get from him.

Re: Cam upgrade/interchangeability????

Re: Cam upgrade/interchangeability????

Probably not now, since the guys is building the turbo to the specs of the motor currently. I mean you could do it, but with the air flow compensations changing, I would re calc the system first, and create a new map.

Re: Cam upgrade/interchangeability????

The 750 and 1000 cams are longer duration so you will move the power further up the rev range, loosing midrange in the process. Some of this can be had back with more compression and other modifications. You will also need to fit adjustable sprockets and dial them in correctly as they are miles out if you drop in. Gains can be almost nothing to losses with really bad timing. Be very careful with higher lift cams if raising the compression as clearances can get very tight. You also need to check valve springs on certain combinations.

So I have a 03 gsxr 600 and I want to put 1000 cams in it, what else do I need to do to make this work? Or is it as simple as pull the old out and put the new in?
