Hmmm... Yes but they are all too small. I need something bigger!
Last thinking was (Bear with me)
Either:
1) Turbo K from one of the Rover 75 turbos, bin the turbo and fit a supercharger, mini one would be cheapest probably but not really big enough
2) Standard K with Landrover MLS headsaver type head gasket without the 20 thou skim to drop the CR a bit, then a mini Eaton or bigger.
Both would need charge cooling IMHO as there isn't really room for an intercooler...
Problem you run up against every time (Apart from the practicalities of fitting!) is the bottom end/pistons/rods are reputedly not up to it. Saying that I could always find out how far you can push them...
The only other options are a VVC bottom end which is reputedly stronger or spending a whole load of cash, which clearly isn't my style...!
Off to check e-bay again...
