I haven't yet. I didnt want to do it half hearted. There a few Turbo'd 106's popping up in the uk at the moment. I am in a secondment role at work at the moment, and when i finally get the job i will be earning a hell of a lot more money than i am now, and a bloody good wage for a 23 year old!
So when i am earning the money, i'm going the whole hog, with a forged steel stroker (pistons, rods and crank) full race camshafts, Full race spec head, Motorsport spec turbo (no off the shelf crap) and i hope to blow the rest out the water so to speak! End of the year is when i will start the build.
P.s. I also got a small Wels Catfish at the weekend. Around a foot long. He is loving it in my pond.
