EFR6758 sounds very nice on paper, but I haven't really seen any 1.8T project with it, so I don't now what power and spool figures ot expect in real world on 1.8T. So I will stick to the GT3076R.
 
I used to run a GT2871R and made 407bhp on a 20vt however this was maxed out and didnt last long. I have since had a full engine rebuild with a GT3071r and am making 475bhp. It pulls really well but can be laggy, you just have to change how you drive slightly. You get used to it and with the extra revs at top end it makes no difference to the car.

hi bully, have you a video to see how is the spool? i was thinking to fit a gtx 3071 to my car

thank you

Did you go for 2litre stroker kit or stick with standard bore etc. when going GT30?
