Don't want to put down anyone, but I'm not really impressed by the 2jz cams numbers.
Here's a dyno I did 2 years ago on stock twins, stock cams, no cam gears.
Upgrades are: 550's, SAFC, A-VCR, 2.5" exhaust, Skyline IC
To translate: 'vermogen' = power in hp, 'koppel' = torque in Nm, the 438Nm equals 323ft-lbs.
So: 300+hp between 5000 - 6700rpm and 300hp up to 7000rpm...
(don't pay attention to the A/F's, they are from a probe in the exhaust which works crappy, we used the on-board AEM-uego and that was all good numbers)
Come on people, you can do better on 2jz cams!
