As the saying goes run it with what you have, tune it and figure it out. Almost everyone blows up their first Turbo Motor. It is part of the game. Upgrade after you smoke this one!
Not everyone blows up their first turbo motor. It was my fourth that took a dive. lol. I agree with Louis, run what you have. I bet it will make over a thousand with a good tune and enough boost. Everyone will tell you this and that will limit power but in reality these motors are really dependant on boost. More boost=more power. Case in point I did a small block Chevy with a .460 lift hydraulic RV cam, unported dart heads, 8:1 compression and the car ran deep in the nines with a stock cast short block out of an Impala that we grabbed out of pick a part. It lived only 10 passes I think but revved to 7k and went over 140 with 2 T04s and 16 pounds of boost. Everyone said it wouldn't run. My point is that turbo cars are still uncharted territory and everyone should make their own way and gather their own data because every set up is different from the rest.
