Lower compression will reduce your horsepower. You have to up your boost to compensate; the advantage of lower compression pistons is that you can run more boost with a lower likelihood of detonation. This is down to a safe map really, I'd be inclined to run slightly lower boost with a higher comp ratio and make damned sure it's mapped properly. The ~10:1 ratio of the IS200 is a bit high for ridiculous boost, but it is by no means impossible to turbo to high horsepower. Alpina get over 400hp on the N55 block with a 10.2:1 compression and fairly low boost.

Basically, simply dropping your compression ratio will reduce your power.

So low boost high compression or should I lower compression and up boost with bigger pulley
