It IS possible, but i wouldnt do it. for the same reason I-6 Supras and I-6 Skylines and vr4s, usually convert to one larger turbo instead of 2 smaller ones, because the top end power more than makes up for the low end spool up, also you have to consider that we only have two cylinders to push each one instead of three. in my opinion, twin turboing should be left to v configuration engines (v6, v8). i remember hearing about some pro, that has a TT Gsr and i guess its way fast but the single turbo guys are faster, and you would have to put tiny turbos on to fit in the body of a street car, especially with an h23 But that would be pretty sweet to have a tt h-series. if you go through with it, let us all know how its coming. later
