Also just ordered a SPA T4 Turbo manifold so we'll see how that goes.

Anyone have a good recommendation on a turbo manufacturer? I looked at garret and can't find a GT3584 for under like $1800 and I can't even find compressor maps to size a turbo correct on the Precision or Turbonetics website

69 Buick Special Deluxe. Intercooled Turbo Chevy 250 @ 15psi on a stock long block. It's kinda fast.
