I thought some of you here might like this, a swedish RS200 Evo with an F1 turbo. On the top of it all, it's street legal. With a smaller turbo and lower boost (1,9 bar) it gave 630 bhp on the dyno. Haven't been tested after the turbo change and upgraded boost to 2,2 bar.
If there is any demand for it, I can do a translation of the review.
