Don't know if this is a repost, but I've not seen it before. Quite an interesting comparison of the AP1 and AP2 cars, plus another comparison with the Spoon F20 2.2L kit.

Clicky

 

Thanks for posting very interesing.

What they dont tell you is that they changed the transmission ratios too in the AP2, but same FD ratio of 4.10.

A tighter secondary gear reduction ratio (1.206 vs 1.16) to provide a bit more snap off the line and to better match the characteristics of the new motor.
4% shorter ratios for 1st through 4th gears while the 5th ratio is effectively 1% shorter and 6th is effectively 2% longer, for a slightly more relaxed cruise speed. 5th gear ratio changed from 0.971 to 0.942. 6th gear ratio changed from 0.811 to 0.763.

I believe there were quite a few changes with the AP2 not jus the engine.

162 ft lb max torque.

With mods i have 170.4 ft lb, just over 250BHP and 4.57r final drive.

I love the jap videos the humour and technical explanations esp from Spoon.
