This is what autodelta sells for the 3ltr 24v with a rotrex. Rotrex is more efficient on high rpm. But can the lower cr of the 2.512v make up the 3.0 24v with higher cr and more breathing capacity?

I was thinking port the intake and exhaust ports it to 3.0 port size, 3.0 valves, use low overlap high lift cams.The GTV6 with the 2.5 24V drift car in northern europe (forgot which country) is making tons of power 300-400 bhp. If the 2.5 with high boost can make 300 bhp, that would e great. I think Greg Gordon got 200 bhp for a basic setup with twin scroll SC in a stock GTV6 with low boost.

Had two oil leaks on both valve covers. So removed them. Also made some baffleling in them while I was at it for the crank case breathers so they won't suc up oil which is bad for detonation and a lot of other stuff.

Also in my search on the web I came across some nice vvt solution:

I think I can fabricate something like this myself and Bench test it on a lathe for rpm switch settings. But first check on the dyno if we can gain power with adjusting the cams.

Ported the blower for lower temps. They sky rocket wonce you exceed the 14000rpm limit where the normal m62 unit was designed for. So I copied the inlet side of an mp62 unit which is the performance model and can rev up to 16000rpm.

Made a section view of the rotor and copied the contour:
