Hahn Or Greddy FMIC, come here if you have one...

[DavisGST]

I have 97 GST, am running the small core Greddy FMIC. I ran it with the stock, Big 16G and now the 20G. It handles all three turbos with no problem. The 20G is now running 20 psi and seems to have no problems. I don't get boost creep because of the Tial wastegate.

The only problem you are going to encounter with all these big FMIC is that when you bolt on any turbo beyond the 16G, you are going to run into heat issue. The FMIC is going block the air flow to your radiator and turbo. Just be prepared to upgrade your radiator and fans!

I'm from Socal and I go to Road Race Engineering web site alot. Check out their Griffth FMIC (if it is not too late), the price seems right. They got some data on the FMIC.

What ever you decide, just check yourself and don't wreck yourself leave it to those scubie drivers!
