I have a St170 engine I want to turbo.

I wanted a blacktop to start but the ST came along cheap so why not, its much newer than an old blacktop and has a better head...

Anyway, this has thrown up some questions??

The pistons and rods are different to standard fair but I'm wondering if its just a simple matter of throwing in a set of low comp cosworth or wossner forged jobs on the standard rods.

Are the rods in the ST170 the same dimensions as a blacktop? length, pin size.. Or, do I need special pistons?

Then there's the cams. ST ones are very lumpy and there's the VVT. Does this work in a turbo setup or is it best to fix the inlet to limit the overlap??

Any help would be much appreciated
