Well the car is already over 200bhp (torque about the same).
The engine was fully rebuilt when the conversion was done, the rings were uprated and the compression ratio was lowered to 8.5:1 by offset bushing the conrods. Its running a Garrett T25 Turbo with switchable boost control and ERL Aquamist water injection. Fueling is taken care of by an additional 4 injectors which are controlled by a k-star management system.
Why would I want to put a mk3 engine in?
With the Nos idea, I was thinking of just running a 25 or maybe 50 Bhp jet, just for fun!!!
My biggest worry would be the gearbox, my car eats them! I have been through 4 standard mk2 16v boxes and one rebuilt box with bolted diff. Having said that, I went to a mk3 box and that's lasted longer than the rest put together so far!
