there's a thread recently on here somewhere about DIY headporting. I know Braineak posted info on it.

thanks again

yeah thread "home brew head work"

i got pics and logs.

NeoGenesis2004 did the work. talk to him about it. I wasn't brave (competent) enough to do it myself.

Can you fit a 3" DP?

TurboTim 10-12-2007 08:43 AM

On a greddy? Maybe. I'd be difficult. On almost any other turbo position? Yeah.

7psi @2200, 3'' dp ftw

i went from the stock greddy to a 2.75 swagged dp with 3inch dp back exhaust, talk about a difference, turbo spool is so much quicker down low, making boost at 2500 instead of 3500, and getting full boost by 3500 has been worth it. Granted it will be a tight fit but its worth it in the end.
