Hello all, not sure if this is the best place to ask about some info on the Abarth engine?.

I have a Abarth 595 engine (312A1) to go in my project build.

Any info on where to get wiring diagrams, pinouts, fuel pressure, what boost does stock turbo produce, coolant hose layout, ect.

Any links to any info like the above would be much appreciated.

What project is it for?

Welcome to the forum.

The engine will be going in a Toyota MR2 MK3.

Fiat integrate so much stuff across the car you are probably better with a programmable engine ECU. SImply using the Fiat engine ECU alone will raise errors and might even stop it working at all.
