A friend of mine had a saab 9000 turbo (which I think is basically a cav turbo underneath) runnin about 280hp, which went like fuck for a big car imo. A lad on hear bought it, cant remember his name, but im sure he'll agree with me.

Another m8 of mine just put a c20let in a corsa with an f28 box(6speed) with quaife diff, also runnin somewhere between 250-280bhp, which in total has cost him I think about 2k. As you can imagine that goes like a stabbed rat. A LOT of performance for not alot of cash I think, and if you find a good engine to start with, pretty reliable too like as allready been mentioned.

I would personally sell the xe to fund a let conversion, as it would suit a cav more than sum high revvin na lump. Even a standard LET would be like night/day compared to an xe
