advice needed on turbocharging type4

[1500SBR]

Bugdawg,

It seems as though your turbo is too big. To spin that you would need big carbs, big heads and an 8000+ rpm capability. It would also work well for high boost applications. Further, I think that for a draw through design, the carb is WAY too small. A smaller turbo (T3 turbine) would work fine with this carb if it was a blow through setup.

We use a lot of turbocharging here in Brazil and we don't waste time on draw through.

If I can help you any further, don't hesitate to contact me
