Porting stock TB/P

00PerfRedGT · 07-31-2007, 04:19 PM

I just started thinking about running an aftermarket TB/P on my car and then I thought about porting my stock pieces. How much can they be ported? I want atleast 75mm, is that possible?

no. The shape of the stock plenum doesn't lend itself well to good flow. You really have to know what you're doing to get a good result. I do but that's an insane amount of work for so little gain. Since you have a blower it will probably help to go to a C&L plenum and Accufab 75mm TB. Those are the best quality. You'll want to jump on a dyno and check the AF after you do the swap. It may lean out a bit.
