I am interested in experienced peoples opinions on DIY throttlebodies. Which are easiest and most effect. Also will '98 CBR 900rr throttle bodies work and what size are they if anyone knows. Thanks.

 

if your going for most perfomance then i think the gsxr itb are the best to work with cause you can get a straight shot in to each cyinder

how ever the honda itbs are easier to get working with the stock honda ecu liek tps and what not

I know other people beleive that to, but check out the setup a customer brought in for me to do some work on. Pretty straight if you ask me.

 

i am using the honda cbr929 ones. the tps is the same as the honda cars so you don't need to reclock them. straight shot in the cylinder also.

But you do have to switch the 2 wires around.

 

Thanks for the responses, keep 'em goin! What year throttle bodies are you guys using and what kind of engines do you have? Anyone wanna post there dyno?

 

so the 929 is the easiest to set up?

 

prob;y the beasiest yes ...i wasnt thinking but im on a f20 (h22) and i had to space mine alot ...but that looks pretty dam straing

I actually prefer the GSXR 1000 setup due to the larger size throttle bodies and the ability to space the throttle bodies to get an equal length runner setup as opposed to the ever-so-common unequal length setup. The car will run alright with no tuning and the stock Suzuki TPS, however you will need to have your ECU tuned to compensate for the incorrect TPS voltage. Also, the stock fuel maps aren't near what they need to be, however you'll run into this problem with the CBR setup as well.

 

what is the size difference between 929rr, gsxr750 and gsxr1000 tbs. I heard the 750 & 1000 are the same from 01 up, is that true? How much power will each support? anyone know.

Thank you
