I was lucky, bought a really well set up golf running 480 bhp and 460lb torque, was development car for APR and VWR so fortune was spent on it but with more power coming really need 4wd, i now have all the parts bar transfer box which is coming saturday i hope, its cost me just under £1300 quid for all parts, was really lucky, the guy i bought most parts of was collecting parts for 4wd conversion until his engine went tits up so lost intrest, he also chucked in a complete gearbox to for pennies, happy days. for fitting of all this you will need to speak to Andy for price, but as a guide i'll be looking at just over £4000, yes its expensive but with the Bigger Turbo, i should be making near 600 bhp and all for less than £16000 inc car i've just bought, watch out supercars lol.
