I don't think it's stupid, but I think it takes a big brass pair to boost an ITR, in Germany, and put budget constraints on the project. I think finding a tuner, accustomed to working on such a project, successfully, may be the first step. The ITR engine is a thing of beauty, and if booster right, it can be even better. However, a bad tune, combined with stock internals, could be a devastating combination. I'd say, in addition to your turbo budget, have additional funds, in case you have to replace your engine. I know many people have learned the hard way to build it right the first time.nutbuster123 on Mar/03/11 said:Im hoping the lack of comments represents that I'm going about this the right way and not because I'm doing something so stupid that takes everyone's breath away
Don't forget their will be little things, like a catch can, and welding an oil return on the pan. Since you're going to have the head off, the clutch out, and probably the oil pan off, I think I'd consider the extra time and money of adding forged pistons, if not rods and pistons.
I wish you much much success with this project, I will be looking in, and if it goes really well, I think I'll boost my GSR too.
