I have a RWD motor that came out of a JDM AE86 available.
It has a small port head that hasthe big port to small port adapter plate in between a RWD manifold assy.
It is a complet motor with a lightened flywheel and clutch setup, full RWD water / Alternator / Coil igniter / RWD loomk and the ECU has a piggy back xtra fuel adjuster cpu with it.
Apparently it was a responsive and better motor than standard i was told before the car was cut. I checked the cams but it doen't seem to have anything special in it.
Complete setup $ 1650
Freight to Syd $175
PM if interested with an email address and i will get some pics of it to yah
