Not yet ;)

Its a possibility for project VX though, looks like there is plenty of room to increase the size of the inlets AND exhausts.

Damn looks like i will have to get larger exhaust valves custom made.

the VR4 forum disapeared for awhile

well my bookmark couldnt locate it and i only just recently found it again

Mine is running ok accept for the idle speed control, might have to try something differant again, clutch is still slipping somewhere over 300 Hp.

But i been running it on 18 Lb boost on this engine, since i blew the first engine and it is holding togeather, just pushed the rev limiter out to 8500 so i dont hit so often like i did when i had it on 7500.

I use it as a daily driver so it is a bit hard to take it off the road at the moment, need to source anouther car to drive so i can do some major work to it.
