I bought a black 99 Si about 2 months ago and love this fkin car!!! It already had a full exhaust, but other than that was stock. I just ordered an AEM v2 and some NGK plugs and wires. I'm wanting to order a Skunk2 throttle body and that's where I'd like some input. Would you go with 68 or 70 mm? Keep in mind that right now the motor will be stock except for intake/exhaust. I'm curious if there is such thing as going too big on the throttle body for a stock engine. I plan on doing a Jackson Racing supercharger down the road so that's why I was leaning toward the 70. Thanks in advance for any responses.

 

leave the stock tb on there. if you do get a sc, get an itr tb which is like 64mm. you dont need to go huge with it.

 

you should have got a regular AEM CAI instead of the v2. A lot of people are just not satisfied with the v2s.
