there are a few guys running turbos that run over 400hp. It won't be much more then 200hp unless you go with forced induction.

Think PPF have just extracted over 700bhp from an M20 using the diesel crank to give a 2.7 plus some decent management, big intercooler, giant turbo and a trick inlet manifold......and then there's the rods, pistons and cams.

If you've got a lot to spend, you can make silly power :D

Something like a S38B36 or S50B32. If you want that in english E34 M5 3.8 engine and a E36 M3 evo engine.

here we go!

i would get a cam, 6 branch, head work, 3 or 5 angle valve, big bore throttle body and a good re map.

it will rev it's tits off, you will lose some bottom end torque but it will fly for a 325i after 3500rpm and make a "proper" 190bhp or there abouts. That would keep me smiling for a while!

that lot will cost u a good dollop to get done aswell
