I got my Skunk2 Intake Manifold and an ITR AEM CAI for my car. Now... should I just use my stock Throttle Body (60mm), or should I go bigger? I heard its not good if its TOO big.

What Throttle Body should I use if I should replace it? What size?

 

Just get your stock one overbored. I heard 64-66 is all you will ever need on an NA setup. I have a bored out B16 one sitting next to me. Its 64mm. Talk to "Spaceballs the lunchbox". He bored mine, I have yet to try it out.

 

Just use your stock throttle body for now. It should suffice. I would recommend getting a non-gsr throttle rotor so you can mount your throttle cable properly, allowing you to use your strut bar.

 

I sent out my 95 GSR T-body to AEM for porting and thats what I use now on my Skunk 2 Manifold.

 

Keep the stock one on untill you tune it. If the MAP dips below 16 psi or 1 bar ( I think that's right, I'll have to get back to you on specific numbers) then you would need a larger TB. Otherwise it shouldn't be needed.

 

Yea. I know alot of people who run on Stock GS-R TB with their Skunk2 Intake Manifold...

 

I would be interested in seeing some dyno numbers from a TB -- my bud dan got a 64mm TB with his ITR IM (on a b17), and said the difference was fairly negligable (he is also ITR cammed). Anyway...I don't know if I'll be doing a TB before I get it tuned. I guess he isn't running as aggressive cams as our Stage 1's Skunk2nr...but if you get a 64mm or 62mm TB, let me know how it goes. Im tuning in late march, so I'd wanna get it done by then.

 

For sure.


I'm gonna tune my car after I get some more stuff into it. I just got the Skunk2 Intake Manifold and ITR AEM CAI. So now I need a JDM 4-1 Header, 2.5" inch Cat., Skunk2 Valvesprings and Retainers, and a Skunk2 ECU.

I'll be tuning it after all that goes in, and I expect my numbers to jump...

 

I have a 64mm to match the intake manifold, but it made no more power on the dyno..Waste of money..

 

Aite cool. Thanks for the heads up. I'll be stickin with the stock GS-R TB then.
