ok will a b18 LS trottle body and fuel rail work on a gsr???????

The Kurnel

to the best of my knowledge (which isnt much) a ls fuel rail and throttle body should work on your gsr, as long as both throttle bodies are 81mm i wouldnt see why not, and the fuel rail will work because if im not mistaken they are both 240cc but idk what kind of gas mileage youll be getting, im sure most wouldnt recommend it but if u need a quick fix. im basing this off an ls/vtec swap im working on, but also like i said im not the most or even close to best knowledgable its my first swap so i hope what im telling you is right! if not someone please by all means correct me, good luck man

The Kurnel

CORRECTION...wow my bad i was way off dont know where the 81mm throttle body came from haha, guess my brain is stuck on this swap... i ran across this guide because i was curious myself, but i still dont know if the fact that itll bolt up means itll work for your gsr
