gday im wanting to see what people run in their high power ef xr6s im wanting to turbo and build a forged short block for my 95 ef xr6 and aim for over 500hp what types of engine combos are out there in regards to e series engine combos making loads ofpower?

Are you talking at the wheels?

500hp is approx 375kW.

yep we are building an engine from scratch my car currently has a jmm dev4 kit in it so my plan is to get my head rebuilt with a bigger cam so it can handle the power
