Do we share a throttle body with the EVO?

 

No. Ours is throttle-by-wire, theirs has the throttle cable connected directly to it.

Theirs *might* bolt up, but it's not the same.

 

the only thing you can do with our tb is take it off your car for a week give it to someone who knows how to bore it out and add a larger butterfly flapper on it .this will only give you better throttle response no horse power and i think the ralliart has enough throttle response ,its pretty peppy.i would only enlarge it if i had a larger intake manifold.

 

i see guys who offer evo TB bored to 65mm. and was wondering if it would fit.

i know rpw offers them but shipping would be less then half coming from someone in the states

 

I have yet to see someone who is able to bore out throttle body. Boring it would most likely damage the sensors in it. RPW claims to have a larger one coming up, but not sure where it's coming from.

 

i've also asked joe's evo 8 about it and im trying a few machine shops over the weekend for this and also pricing out just porting the head because i want to do the polish work on my own. and tomorow im ordering the new RRM camshaft.

 

I am sure our machine shop could do the work although I cannot say it would get you anything. I asked RRM about this a long time and they said it was not worth it.

I would not want to kill a TB by something not going right. EVO TB's have been done for a while now.

 

no problem... as for the head i went to a shop today and the guy said at least 400 just to port it, needs to see the head first. im going to try a few more shops and see what happens.
