You can lol but then you haven't seen a HKS low mount cast manifold with a GT30 based turbo on it which requires a shave of the engine mount (due to the lack of room) but to add insult to injury I have an ex-S1 Stagea RB25 in the R33 and the oil drain sits higher than the original block which means that there is almost no way to reconnect the drain.
I wouldn't never complain about space constraints otherwise, certainly compared to the tight packaging on VQ powered stageas.
The turbo was maxed out in Mick's case and seemingly on Scotty's at similar power levels so dyno-wise I think the results were comparable. To me it indicated that the compressors were maxed out. Mick's setup on E85 is a peach.
My GT3076 was stronger everywhere compared to Mick's GTX3071 on 98 ron both tuned at Unigroup which is why I still think the extra coin required for a GTX turbo doesn't get you ahead of what was already available. I am pretty sure my GT3040 would perform line ball with a GTX3076. The 82mm comp was limited on 98ron but with E85 it would make a low budget +350rwkw.
