I was browsing the import builders site today looking for parts for my all motor build and they have good prices on supertech stuff, I'm just wondering if those prices are low because the quality is low or is that just a good deal.
is there anyone here running their nitrate coated valves or anything from them?
i bought the supertech valves for my car. Unfortunately i never installed them cuz i sold all my head build parts. www.portflow.com sells them and they are one of the best machine shops in the country.
I'm just put supertech valves in my B18C-r, as soon as the build is done I'll let you know how I made out. However, I also heard great things about them
My friend got some of them from RM a while ago, he used them with RM gen 1 springs......he had a valve break and another one had mushroomed. Weather it was a valve problem, or the very high seat pressure of the gen 1 springs it is hard to say.
