Short Throttle Bodies?

[kimokalihi]

Did the JDM legacys have shorter throttle bodies than ours? And if so, did they use the same TPS as ours?

I'm trying to figure out if there's a shorter throttle body than the EJ22T I have because it's making the intercooler installation harder.

Here's a reference picture comparing the length of the inlets on an 92 EJ22T throttle body and a 97 JDM EJ20G throttle body.

They're back to back with the EJ22T on the left. I can't cut anything off the inlet of the EJ22T because the throttle bracket thing is in the way.

don't know about TPS, jdm one looks stubbier tho

I remember old top mounts caused people to cut the throttle body, but I certainly didn't need to in making room for the '06

what year IC you have? the '06+ ones can be had so inexpensively now....

Agreed. There are no clearance issues with the 06/07 WRX TMIC's -- well in regards to the firewall, etc.

I have the 06 TMIC but the problem isn't with the intercooler it's with the Samco Y pipe not reaching the TD04 outlet.

I guess I'll just have to lengthen it with a piece of pipe. I wonder how I could get a lip on the pipe ends to keep the hoses from coming off.

This has been covered in many of the TMIC installation guides. Yes, you need to extend it -- a 2" exhaust pipe is commonly used.

One really should get the ends rolled. Seems only a few shops have the tool to do this, but it DOES help. Otherwise, crank down those t-clamps tight.

I've shortened my throttle body, it took some time and patience.. but turned out well! I removed 1/2"

Very interesting. I'm assuming you did that to fit that intercooler and not to allow your silicone Ypipe to reach the turbo? I don't know if 1/2" would be enough to allow it to reach my turbo.

Yeah, it was to get it to clear the throttlebody. No hammering of the firewall required!

I used some 2" aluminum pipe and some hoses from the wrx and cut em and put the aluminum pipe in the middle to stretch it out It actually worked well!
