PPF Turbo forum

Hi everyone.

I wonder if you guys could help me please -from the basics I can understand from the forum (through Google translate) it seems you guys know your stuff.

I have a 1992 E34 Touring 525i, non-vanos.

I want to build and engine capable of running a turbo. I'm aiming for over 500 bhp.

Can you guys tell me what I need?

Different crank and rods?
Lower the compression and if so how?
ARP -which parts do I need?
I would prefer a Holset turbo, but which one?

This is a budget build, but I want to make sure it gets done right. It will be a road car, maybe one or two track days.

Is e85 available in UK? Otherwise 500hp will be hard to reach on tight budget
500hp setup = Cooperring,ARP headstuds,e85 fuel, Adjustable aftermarket injectionsystem, bigger injectors 1000-1260cc, heavyduty clutch, uppgraded fuelsystem, Turbo + manifold etc
