would a gsr throttle body bolt right on up to a b16a?

 

hmm i cant tell you whether or not it will bolt right up, but larger bore and aftermarket throttle bodies are BS 99% of the time unless your car has a good sized lift cam in it and is just starving for air. aftermarket TBs run around $2-300 and im sure a gs-r throttle body is a hell of a lot cheaper but for the dough you could hop on a dyno and see what your a/f situation is like. youll pull 50x more power out of a good tune then you would an aftermarket TB. just my $.02...

 

thats kool, but im not doing that im getting a complete gsr TB for real cheap with all sensors cause my tps is fuked and i hate the map sensor not being on top of the TB so im gonna get this one but i need to know if it bolts up.

 

Yes, it will bolt on.

 

When i got my STR 68mm (thanks Boostfed!) it pulled a good deal harder on the top end and it was a noticable differance. Also if you want to keep your daily drivablitly don't put a aftermarket TB on the spring is so much stiffer and it is either open or closed (no it isn't sticking) that is my opinion. U want a bigger TB have yours bored out to 64

 

is your car boosted? i just dont see a throttle body being the biggest choke-up point on an unported (intake manifold and head) intake system. but if it worked for you, great

 

Yes it is boosted

68mm TB with Skunk2 opened it up really really nice.

 

well on my d16y8 i put a 98 h22 throttle body on there and it made the engine quite a bit more responsive. my stock one was 56mm and 62mm is the h22 unit. i like it a lot

 

yes, because they are the same.
