My hg is leaking oil externaly and i will be replacing it in the next couple of months. I have a 93 turbo, bolt ons, 92-94 octane fuel, ct-27 (installing same time as hg), running at 18-19 psi.
I need to know which hg you guys recommend, what thickness and if possible, how much it should the part cost?
What is the stock bore size?
Is it better to have a thicker hg with a stock bottom?
Thanks.
