I am on club3g but I have a 8g galant. My pistons are custom spec'd by RRE and I was told by RRE that 8k is the absolute most the motor would take, they told me im much better off making 7500 my redline considering I want the motor to last a while.

There are two other members on club3g, Slava and Napalm who both have 2.4 DOHCs who also redline out at 7500. the rod angles are very similar to that of a 2.3 4G63 setup.

I am running 9:1 compression with my intake cam advanced about 6 degrees and the car is powerful out of boost, very fun street motor and doesnt seem to fall off up top. I havent been on a dyno yet, once I turn up the boost and dyno it, I have a feeling im gonna have to retard the intake cam a bit in order to keep the power climbing to redline.

Just out of curiousity, is it possible to just use the 9 head with the 4g64 block?

dude the acd doesnt have anything to do with the main ECU.

you cant use an 8 head on the 9. simple reason:

theres a mivec oil retun line on the back of the 9 head, that goes back to the motor. the 8;s dont have this.
