Yeah, the weight was an issue i was lookng at, but the gearbox might not be an issue, i could be wrong on this, but i think you can put a 1.8 flywheel on the 2.0 or ST170 engine, and then the IB5 would mount up to it! That way you would only need to make an engine side mount! Obviusly for big power, youd need to change the internals of the box, but then for big power, youd probarbly change the internals of the 2.0 box (MTX i think). Im sure someone with more knowlege will correct me if im wrong. Also the fiesta diesel duratorque box mounts up to the 2.0 engine, and has identical mounts as the Puma. The only thing im unsure about is if the blacktop and silvertop have different gearbox sides, if they do, then the options above are probarbly for the silvertop engine. I did look into the V6 st220 engine, but just a brief look at 1 (the mazda version), theres no way i could get that thing into a puma, its a monster, but imagine it with a big supercharger on the top like the american muscle cars have!! 400 horses anyone??!!!! :shock:
The ST150 might be the best option i think, and probarbly the easiest option!! That engine isnt pushing out alot of power for a 2.0, i think your right, you could squeeze about 300 horses out of it with not too much forced induction work! But then some might say why mess around putting it in a puma, why not just get an ST150??
