Hey guys, I might be getting my hands on 2 R34 Ceramic Turbo's.

Couple Questions:

1a.) How much (roughly) would it cost to make a custom exhaust manifold + Downpipes?
1b.) Does the RB26DETT Manifold bolt onto the M50?
2.) The Intercooler can only be mounted behind the radiator(fan delete) or cut the center portion of the stock bumper...which is better?
3.) How much PSI can a stock M50 handle SAFELY?
4.) On a ratio of 1 to 10 (10 being the most difficult): How hard would the whole setup be?

Thoughts/Idea's?
