I dislike threads like this... interesting.
Sorry but I dont class a 335D anywhere near fun. They are so smooth... if you want a TDi to drive like a grandad then yes. Otherwise the 123D is more like it.
Dont know how anyone can think 3k just for a turbo fitted is right ROLF!
You also cant exchange a PD130 turbo Dan, and the exhaust would cost a little more than £200 unless you get mates rates. Also the clutches that can be bought for £500? They can handle 400lb.ft can they?
End of the day 240bhp is cheap to get from a PD130/PD150. Its the rest, like coilovers, brakes, LSD, arbs, strut braces, bushes, tyres, wheels, spacers that are going to cost.
