I have a 2.2 '97 sunfire and I am getting an AEM intake and i was wondering if a bigger throttle body would be better since i will be having more airflow to the motor???

The stock system is restrictive in on it's self. Getting an AEM intake will help get you more power... a larger TB will help also, but your not going to see most of that power untill you do your exhaust.

Think if your TB as your car's mouth, the engine is the stomach and the exhaust system as the pooper. The bigger the bite, the bigger the "pooper" needs to be to get everything out in a confey manor

^^ great explaination!

think about this...

that's the answer to your question

that is true....but you must also remember that the stomach can only process so much...

port the head and get lumpy cams with the intake and exhaust and you will be golden.

thats funny. im gonna have to remember that one.

but what he says is true. thats a good way of putting it

So then what would you relate to one of those civics I see driving around with a 5" exhaust tip?
I know someone on this site will take this too litteral and stick a turbo in their a$$ next time they get really hungry so they can down more food.

The way I would relate to the Civics with 5 in. exhaust tips is that they downed too mich rice and had to get it out somehow

i ported my stock tb and it felt like i added a few ponies on the butt dyno. especially in the upper rpms. so i figure youll get a pretty good gane if you get a bigger one altogether.

Nice One!




New Picture comming this summer.

alright thanks guys...great explaination...i am planning on getting an exhaust also.. but could i just get the 2.4 TB?? will that fit on the 2.2? and if i did happen to get a bigger TB will the throttle response be slower than with the smaller TB??

the 2.2 and 2.4 TB are both the same size, 52 mm. Go get urself one off a 95 2.3 cavie. they are 56mm

You can't use the 2.4L TB on the '97 2.2L. The TB is cast intregal with the intake plenum, they are one piece. You can get the TB bored out and have a throttle blade made, like I did, or get one thats already bored.http://www.rsmracing.com has the TB/Plenum for $260.00+50.00 Core,they also have the ported lower intake runners for $199.00. http://www.jbodyperformance.com has a bored and polished stock one for $198.66. http://mantapart.com has a Special cast intake plenum w/matching 56mm TB for $495.00. There are more out there if you want to do a little more searching.
And yes, you will lose a little throttle response and a little low end torque, since you will be losing some of the intake velocity, but with the right parts to match(cam, rockers, header, exhaust, P&P head, and gearing in the tranny) you can more then make up for it.
