....sorry to fill up the page a bit here! just had a search and a read about the differences - the two engines are almost completely different! i'm sure you all already knew this actually, but i didnt, being new to seat. different turbo, intercooler, ecu etc.... i'm quite surprised as this surely couldnt be cost effective?? if a 150 turbo was fitted to a 130, it seems the boost temps would go through the roof without the ic to go with it!!! i wonder why the same engine wasnt used but with different maps to give different powers?
