hey guys,
I hear ppl talking about just how great the evo iii big 16G is,
how does it compare to the evo vii GSR turbo? I have the option to use either on my VR4 motor.

I also have the evo vii manifold to use as well.

thanks guys.

They basically use the same compressor. But the exhaust housing is larger on the VII. If it will fit, go with the twin scroll version from the VII.

yeah it will fit,
just have to move the alternator though, since the turbo would fall right on it.
my setup is rearwheel drive by the way so there's no problem with relocating.

I guess the bigger housing would aid in top end EG flow, and the twin scroll design would improve spool, so it just might be the better of the two, even though they carry the same compressor.

thanks man.
