Shop for porting air-cooled turbo heads
Good morning folks,
I have my '86 930 engine apart to replace broken dilavar head studs. While it's apart I'm looking for a (somewhat) local shop that has some experience drilling for twin plug and porting the intake ports to 38mm while reconditioning the heads. I talked to AA and they don't do the porting work anymore. Thanks all! |

If you want to stay local, call Charlie Murphy at Intersport in Tysons 703 242 8680. He will give you straight options. FWIW, I originally wanted to go with twin plug on my 79 930. Several techs talked me out of that. I did send the PCs to EBS for compression shave and ceramic skirt coating. I went with Motec, Carrera intake and larger ports/injectors too.
Good luck!

I've also used Xtreme for several sets of heads. Good consult, beautiful work, not local.
