whats been done to your golf altogether then barry?.. got any pics/advice on the 4x4 tranny conversion?.
i know the boot floor panel needs changing..
also on the topic of nitrous, if rods were upgraded then progressive shouldnt really be needed i would assume.
if i were to fit before the rods were fitted i would only fit something like 30-50bhp jets to keep it under the 300 bhp margin.
long term plans are to build an engine that can handle it, or give up the cars altogether and buy a shopping wagon.
