Re: Throttle body

If you plan on doing thise to your stock one, all you have to do is disconnect your vaccume lines and sensors etc. and remove the... i believe its 4 bolts holding it to the intake mani.... remove your engine

Re: Throttle body

What size TB should i get for the best performance. Ive seen some that are 62mm but a lot of people have bought 59mm(i think thatwas the size). What would be the performance diff. Is the 62mm to big.

Re: Throttle body

the second gens and 95-97 had 52mm stock TB, which can be bored to 59mm max. The newer motors (2200, EcoTec, 2.3 & 2.4) have a different TB and it can be bored to 62mm. RSM Racing has a few, but you could get it done cheaper if you know the right people and do it locally. My advice is to go to a junkyard and grab another TB and have it bored, that way you can still drive while it's being done and if they muck it up you haven't totally screwed yourself out of a ride for a few days.

Re: Throttle body

I would bet that if RSM is boring them to 62mm that it's not too big, your ECU is gonna add more fuel to compensate for the extra air. I also bet it won't be too much for the stock fuel system to handle. IMO this could be the most bang for the buck, cheap-er upgrade.

Re: Throttle body

so 59mm would work fine for my car. How much power do you think this mod will add.

Re: Throttle body

CRJ you said it was easy to take out if i was to get my stock TB bored out. Is it going to be the same if i ordered one online that was made for my car.
