I am building/built a TT 427 small block for my car. Its now time to decide on turbos. I don't want to see hardly any boost below 3000rpm...... I was thinking two T3 or T4 w/a .6 or so A/R, what is everybodys opinion on that? This setup will also be twin intercooled too. Thanks

try two 60-1's

 

this really depends on how much hp you want and at what boost. Rick @ Innovative Turbo has a 427 sbc in his 89 camaro and he is running twin turbos. Maybe you should give him a call: 805.526.5400 Good luck

 

the t-3's will definitely be too small if you dont want boost down low. You would be more likely to find a couple higher a/r t04's for a decent price. Those would flow enough to support a 427 also.

just my 02
