What mods do you have on your e30. That is a ton of HP for such a light car. It must hall ass. I saw your vid, it was sweet.
How many miles have you put on the turbo? What turbo? Is your e30 your DD? Do you have an e36 M3?
I have a ton of questions. Once I have my suspension sorted out, I have contemplated F/I and I am in the process of doing my homework.
