I know that a throttle body from the 06 engines works, and they are bigger. but would a 2003 Mitsubishi Eclipse 2.4L SOHC 4G64 throttle body work on a 2009 gts? seems like it would, and those throttle bodies are biggest we could apply i believe. this throttle body combined with an aftermarket exhaust seems like itd produce considerable gains.



edit- actually take that back, i think we would need the 07+ 4G64 eclipse spyder throttle bodies because theyre electric. any details?

 

does anybody know of any throttle body upgrade for our 2009 gts at all?

 

You can fit a RA or TB.

I have bored mine out and fitted a 61mm butterfly to mine.

 

did you bore yours out yourself, or did you have someone bore it for you? last question, do you know the size of the RA tb?
