What's all done to your pickup, tranny, gauges, EFI, etc.?
Do you have any specific goals you're shooting for?
I port/polish the IHI and get quick spool up and good power increases. Click on the link and go to post #13. I posted a spread sheet of results for IHI wheels I've tested.
LB7 Wheel Testing
If you have any questions let me know.
The stealth 64 is stock IHI that has the compressor cover machined to accept a 64mm 7+7 cast wheel off of a borg warner S364 turbo. Theres also a sleeve to fill the void due to the diameter difference of the stock iHI turbine wheel and S364 compressor wheel.
When you've got time, fill out your signature so people can help out in making recommendations.
