Hello, power with that spec will be more like 250hp.

The turbo can be fitted, but doesn't go straight on - the problem is with the exhaust housing. As you said, they both have studs - that is easy, you take the studs out of the turbo, and drill out the threads. Then you bolt it as normal.

Next, you will notice that your exhause will not mate onto the cosworth turbo. The RST elbow will not fit onto the housing - it uses 5 bolts, the cosworth 3. You can either get a cosworth downpipe, and have it modified to clamp tou your exhaust, or.... there is a guy in germany that makes an adpator for around 100 pounds - then it bolts straight on.

You then need to rotate the housings on the turbo core, so everything lines up. You loosen the six bolts that hold each housing to the core, and rotate them to the same angle as the std turbo. The exhaust side will probably be VERY difficult to turn - heat it if you can.

Rick.
