I have an Aebs Intake Manifold on the GSR motor im putting in my CRX. I was wonder what size aftermarket throttle body i could use? should i use a throttle body spacer? In what way do this minor mods help?

 

a larger throttle body will only increase your idle and decrease you mpg.
If your engine is N/A, then your motor is already getting enough air in it to perform at its best, a larger throttle body will decrease your intake velocity, giving you less hp. I'd say to stick with the stock one.

Not sure on the spacer, if it's anything like the intake manifold one that creates a gap between itself and the engine, giving cooler air. Than that one must make a gap between the throttle body and manifold, also for cooler air.

You'll most likely get the most power with the spacer and bypassing the coolant lines on your stock throttle body.

But if you have a turbo. You could get both the larger throttle body and spacer. I don't know much on turbos, but I think you would just get more out of your boost.

 

Port match, Find out what size the IM is and get a TB the same size.

 

what about the aebs im and tb both 65mm

 

Well i don't have any real intention of putting a turbo in my car, atleast anytime soon if i do. So it sounds like i shouldn't get a bigger throttle body. But what about the Aebs Intake Manifold, should i not use it.....got it with the motor.

 

So no one knows if having an aftermarket intake manifold on an N/A GSR motor is a good/bad idea?

 

what are your plans for it?

 

My plans for it...well i guess it would be to make it a fast N/A car that i'll take to the track occationally
