UPDATE: Thanks Baz, but I'm using genuine bearings. I've sourced all my parts basically all from the US. Everything I want including a ported, with enlarged wastegate geunine E3 Big 16g at a very good price.
As for turbo. I was thinking real 20g but I'm not wanting to run an external gate. Slowboy can Add an internal gate for $125, but I'm not wanting to do any business with Slowboy. Plus their shipping cost is insane.
At the end of the day I want a earlyish spool, with decent top end. Direct Bolt on to a GT pumps E3 manifold is absolutely necessary, I probably could be bothered getting oil lines made. I'm not wanting to run an external gate because I want the engine to *look* stock. I have about US$1k Could probably stretch that out a bit.
Throw me some suggestions! What power ccould I expect to see form a ported E3 b16g, 650's, WOLF, walbro 255, appropriate cooler and exhaust setup on about 16psi?
