a polo weighs around 850kg, a mk3 golf weighs 1100 kg, so the difference in weight is a couple of fat people. a 1400 abd tuned the the spec i listed will put out in excess of 100 lb/foot of torque, which correct me if im wrong, isnt that far off std 2L 8v torque figures.
If you had bothered to read the whole thread rather than throwing your toys out of the pram, you would have read that I was not advising the person who started the thread to go out and do any of this stuff. He asked how the 120 bhp was achieved from an abd and I told him, nothing more, nothing less. You could probably apply similar tuning tecniques to the 2L 8V, but it would be pointless, as you would struggle to exceed std 16v power, same could be said of the 16v when compared with the vr6 too. if your gonna spend big money tuning, you might aswell use the best engine offered in the chosen model.
The 2e or any other tall block for that matter won't fit in a polo, without spending 2k on a subframe, even then it wont be any quicker than a std g40 and it certainly won't handle any better, due to all that extra weight up front.
heres what my stock polo g40 put out a few months back
7bhp and 9 lb/foot more than a std 2 litre 8v
