Adding Turbo to 3.2 Euro Spec Motor Question?
 

I have done a lot of searching on the forum regarding information on adding a turbo set up on my Carrera. It has been extremely helpful.

I will most likely move forward with a system through Ben at M & K, as well as a Protomotive Chip.

Are there any issues in running a typical 930 type system on a Euro Spec 10:3:1 compression motor? I know boost can be an issue.

Do you think the valve guides will survive?

My goal is 80 to 100 added horsepower.

Thanks in advance.

Hi
No actual experience. Will do it in the future.

I jus want to wish you good luck and follow your progress.

Contact Protomotive. They have a CHIP specifically tuned for the Euro spec motor, but you need to run a little less boost than 0.5bar if you are thinking of the non-intercooled version. At 0.5bar, you should be at around 360HP, so at a guess, at 0.4bar you'd be at around 340HP?

If you want to run more boost, you're in trouble. You'll need to decompress that motor for any more boost, but at 0.4 - 0.45bar boost, you'll reach your 80-100HP goal ;)

Thank you for the help JMA-RUF, I'll discuss the details with Proto and won't run over .4-.45bar boost. I do want to relo the air condenser to make room for an IC.

This engine is in excellent running condition. I want the turbo and added HP, but was a bit nervous regarding running it safely with high compression and stock internals.

I am not an expert but a USA 3.2 has a 9.5/1 compression ratio. Running 6 pounds of boost is like running 11/1 CR which is about at the limit of most street gas.

If a Euro 3.2 with 10.3/1 would have to keep boost down to about 2.5 lbs to achieve a comparable CR.

Basically, it dose not make much sense to turbo a Euro 3.2 without changing out the pistons. A set of J&E turbo pistons should be about $1k. Your euro set has value for resale. With a 8/1 CR set you could run about 11 lbs of boost.
