Re: built head, eprom, dsmlink
Shane's talking about smaller ports on an EVO 8 head. I'm not sure what the EVO 3 has in comparison, probably similar to the 2G since they're similar engines.
The 2G head is very good, Kevin Kwiatkowski runs 9's with one with little to no porting last I heard. From personal experience, I had a heavily ported 1G head on my car and I picked up a noticeable gain in power and spool up going to a cleaned up stockish port 1G head. Basically I learned a lot from my original porting work 7-8 years ago to what I just put on 2-3 years ago. Totally different and much better by the butt dyno on my old setup.
The 2G TB and intake are restrictive unless you want maximum torque with a stockish turbo. Exactly what the designers were looking for.
