why go twin insted of one big turbo......? in looking for suggestions more for a unique proyect for car shows that peformance in 1/4 mile. My first idea was building a natural aspire engine with 500 plus hp with cams,heads, pistons and everytthing you can imagin with engine performance but now i got new dreams and is a 328 is twin turbo withthe same engine that i got right now,but you know forged pistons, head work, microtech ecu, electromotive ignitions and bigger fuel system well everything needed to suport 500+ hp. if any one got an idea regarding twin turbo set ups or pics if they got one i will apreciate any coment or suggestions before i make a decision, we together can make this machine come thru thanks to everyone ......peace
