So, took this for a re-tune after some teething idling problems and over fueling. Well I must say after all the abuse and time the motor still goes sweet, still a frikken animal on the street!

In stock internal standards, I reckon I could eat turbo LS motors for breakfast.

Motor had more in it, but injectors are at 100% duty cycle.

Go the VH45!

I feel sorry for your tires. Any updates on your oiling situation? Still running the RX7 injectors? Any changes to the ring gap?

Man, I love threads like this. High-HP VH builds aren't for everyone, and certainly not simple, but what an awesome powerplant.

so still running oil lines straight into the main galleries at the front of the motor, seems to work pretty good

stock ring gap
stock bottom end
save for a second hand piston I slapped into the motor in place to replace a detonated/cracked piston from the burnout comp I did, how rough is that, I just used some 1200grit wet and dry and just roughed up the bore, even used the old bearing
