Just to get alil deeper into it, the main reason for doing this is bcuz the newer head flows better, and (i think) has 8injectors instead of four like the 01-02 gsxr 1k. Could I get pretty close to the same gains by porting the 01-02 head?
for this project, nope-hence the questions. i have a swingarm, cams, and a 01 head, bcuz i was going to do this to my 750. but i figured i should start with a 1000 and make it easier on myself, and not worry about blowing up my streetbike, and i can still hit the canyons.
from my searching, the 01-02 1k is MUCH cheaper than the 05+. however i did find a wrecked(plastics) 06 for 3500, gonna go check it out.
if i can port the head and get almost the same performance gains as swapping the head, then i'd do that, bcuz thatd be cheaper. im not trying to rotate the earth, i just wana run 9.20s consistently without a pro rider, without spraying it, and preferably without bumping it up to a 1070.
i assumed with a good head(hence the swap question), 750 valve springs, cam swap, along with some good gearing and a good map, sitting at 65" on the lighter 06+ wheels, itll run 9.20s easily. i weigh 155 in street clothes.
