My understanding is that the only real difference between the GT and the 180 is the PCM. Maybe the 180 uses the injectors from the '03. I did read on another board where a guy had S1 installed into his son's 180 and he felt it was the same final result as S1 on his own GT. I think I'll head over there and pick his brain. Hopefully tthrift or 3barboost will have a look at this thread.
Scratch that. Here's the thread, and it's on this forum!
