Gregsyb 4 Posted July 9, 2012 Report Share Posted July 9, 2012 I'm currently in the early stages of my turbo set up and have a question.I phoned up a local head skimming/ engineering company today about skimming my cylinder head whilst I take it off of the car. The owner told me that he would skim it but wouldn't recommend porting or polishing in any way. He said it was messy and wasn't worth the gains.I'm really no expert and very new to this so just wondering if its true? Are ported and polished heads worth it when going turbo? Or would it be better to keep it standard and just get it skimmed?This is my first question on vr6oc though as a whole, the forum seems to be very helpful compared to most.Cheers,GG Link to post Share on other sites

Gregsyb 4 Posted July 12, 2012 Author Report Share Posted July 12, 2012 Thanks for the reply, Why would you suggest leaving it alone? Is it just the price vs. the gains is not worth it? Link to post Share on other sites
FishWick 21 Posted July 12, 2012 Report Share Posted July 12, 2012 Not worth it. As I say, gasket match the intake if you can be bothered but leave the exhaust ports as there's little gain. Link to post Share on other sites
