Well mine's an 8v Carb model, so rubbish really! Gone from 230bhp to 100bhp (& still not found it all!)!
I've had a 16v turbo 900 & that was rapid @ 175bhp! But my 9000 Carlsson was the best @ 210bhp (2.0l version is best, no stupid balancer shafts in the engine, 2.3l gives 230bhp but won't rev as freely!) & if u visit Abbott Racing, 300bhp is reachable!
So just depends what your after? if you can get a 900 Carlsson you'll be in for a real treat!
(& i know how to get rid of the reverse gear ignition lock too!)
