i Had an 820vittesse turbo, they did 2 spec engines(same engine though), one was 180 bhp the other was 200bhp, i had the 180 bhp version and it was great, one of the biggest pains with them is that they pull the threads on the exst manifold and usually its the one under the stat hsg that is the first to go, the g/box's $hit themselves if you up the power too much mine made 220 bhp in the end and i ate 2 gearbox's (albeit with some seious launching).

If you need to speak to somebody, then i can highly recommend motobuild as they always gave me loads of free advice and there supply of parts was 2nd to none
