This is the only place where i trust yalls judgement. Seeing how man people are makin so much power. Well im startin up my turbo project after finding a very good welder. I know my way around turbos, but just wanted to make sure from yall what tried and true parts i should use. Here are my goals on stock motor i wanna run 5lbs and then 7 to 8 with meth( i know i probly could go higher, but i wanna see how long the stock engine will last at this level). After the engine gets built i would like to run 800hp. I was either thinking either a gt-42 or either the new s70 or even a s72 for something to grow into when the hp bug bites.
1. What should i make the tubing out of and what diameter
2. Whats type and how big of a wastegate and how many if i get crazy with the boost.
3. What blow-off
4. should i use a t4 or t6 flange( i know thats dependant on the turbo)
5. What air-to-air intercooler would u use.
6. For an intake manifold wat is the best material to make it out of.
7. Also everything will be coated, but i have heard of mixed reviews between wat to actually coat it with. So wat would u use.

Thats all i can think of right now. Please add anything that u think i would need to just the turbo kit itself. I know i should start off with a smaller turbo and parts and go larger as i need, but money aint growin on trees and the engine will be built soon so i rather see wat i can do with this on a stock engine and only build the turbo kit once and be done with it. Thanks IceN

 

1) Stainless, whatever fits your components
2) up to you
3)Greddy seems to be popular
4) I think you answered that one
5) whatever will fit your application
6) stainless or aluminum if you can find someone to weld it
