Hi all, im new to the site, so go easy!
Always fancied a mk2 gti, and was looking for a bit of a winter project when I came about a knackered 16v on ebay

Havent bought the thing yet, but it would be a bit of a rebuild job as its in need of some hefty TLC.
Anyway - Heard a lot of talk about transplanting the Audi 1.8 turbo engine in, have been told its not that big a job, anyone been there and any advice?
Its one of these written on a napkin projects that may never make it any further, but heres the idea:
Strip shell, repair bodywork, respray to original colour, install rollcage, dash, bucket seats and as little else as possible;
Rebuild 2nd hand Audi A4 1.8t engine, uprated head gasket and recon turbo, decent clutch, golf gearbox, megasquirt DIY ECU, custom intercooler, 2.5" bore exhaust and hopefully a reliable 200bhp with standard internals.
Obviously a brake / suspension / wider wheels upgrade would follow.
Any advice??
