The motor in my R31 in Okinawa:

Stony made some nice changes and upgrades when he had it:

Motor and transmission arrive:

The R31 I am putting it in now:

First get rid of the old RB20:

Empty engine bay:

Need to open up the center of the bumper for the intercooler:

That's better:

Fits like a glove. Also notice I removed all the HICAS stuff in the engine bay and as much wiring as I could. Gonna tuck everything when it's all said and done.

Cut the firewall for the larger bell housing:

The stock rear trans mount was only an inch back from the mounts on the transmission. Made a bracket out of 1 inch plate steel.


Battery relocated to trunk. Going to replace with a nice sealed unit:

Easiest way to stiffen up the rear after removing all the HICAS lines is just welding up the actuators:

Swirl pot and aluminum radiator installed:

Mounted the fuel swirl pot and inline fuel pump in the trunk. -10 from pump to two -8s up the the fuel rail ends with a -8 return. Will be using E85 with 1600cc injectors:

Will be buying the Borg Warner 9174 EFR turbo and engine management will be handled by an AEM V2. I will update thread as I make progress on the build.
