I still need to get my cams tuned but I dont know if i will ever have the time to go to austin and get it tuned at uprev. My exhaust cams do wierd things past 5800 rpms so I am going to disable them in the ecu at 5800 rpms to redline. You guys know for an NA build you can use vq35hr pistons for like 11.5 compression and they are a decent price from nissan.

As for the cam timing changes, was that only limited to 6600rpm on the mrev motor, compared to the Rev-up with VVT on intake and Exhaust sides, and a higher redline?

Much better but that is about all this motor is going to put down with my intake manifold. You can see the power the climbs strong to 6200 rpm then suddenly nose dives. Looks like its just not getting enough air flow. Hopefully the Cosworth manifold will solve this problem.

I need to go back and retune the car...the power level of the car is significantly different after fixing the coil pack and crank sensor. I am dying to know what kinda of numbers I am putting down now.

Actually I bet this would tear a stillen setup a new one... maybe even some ST setups running low boost. It should deffinitely run 12's
