Cool Mini, must be scary fast. Trying to read your build topic, but thanks to Photobucket it is bit mushy. Did you think about Honda engine? Did you re do electrics, cos I was amazed that my 1.0 1989 Mini had as bad electrics as any Mini from 60's. What about suspension and brakes? And what is your best suprice on the road, who/what you got?
A friend of mine had the honda b18 type R engine fitted to his but I prefered the k series for several reasons, his seemed to cost a lot of money to build and tune etc (aftermarket ecu etc) and the heavier engine didn't seem to do the handling any favours. The K series was cheap and readily available, more compact and very light so seemed ideal. Also i could use the standard ecu and engine wiring as it is relatively simple for modern fuel injection. I bought a new mini loom and joined it to the k series engine/ecu loom so the wiring is reliable and i added more fuses and relays to be safe.
Suspension and brakes have all been upgraded, fully adjustable suspension front and rear, kyb adjustable dampers, KAD alloy rear trailing arms, rear ARB, KAD 4 pot billet alloy calipers and high carbon disks up front and turned down alloy drums on the rear. The handling is really good, very neutral and easy to drive at the limit, no oversteer or understeer just goes into a controllable 4 wheel drift if you push too far. Brakes are excellent as well, there is a late mini servo moved to the passenger side with a link bar and for the track i use carbon metallic pads which are excellent.
It does cause some confusion on the road but i'm a sensible driver on public highways so I've had more fun surprising people at the drag strip and on track days. It has easily beat my friends honda engined mini at the drag strip along with various bmws etc. The usual reaction is 'wtf is under the bonnet?'! followed by a good chat - most people don't mind being beaten by when they find out whats powering it, although i've had some bad reactions as well. I wipes the floor with most bmw minis around the track, the only one that nearly managed to keep up was a rally prepared 350+bhp one.
