youd just need a stepper motor controller and i think alot of the ecu's nowdays have one build in for an idle control stepper motor... the hard part would be boring out the 6-ports to the renn diameter,.. im not sure if there enough metal to do it.

From my experience so far you would just use some sort of adaptor plate.



I've currently just put together a 12A turbo with series IV inlet gear to give it some more flow and the top mounted intercooler.

I'll get my hands on a front mount soon and I'll be running dual when the Turbo needs replacing..



The adaptor plate that I'm using is about 13mm wide and this is enough to match up the distance between a 13B and a 12A motor.



Hope I've been able to shed some light..

How is the adapter plate going to make up for the fact that the sleeves are physically to large for the older sleeve holes?

I would say use some aluminium stock to make a sleeve the right diameter. Then cut the sleeve to match the porting of the renesis. All the sleeve does is direct the airflow the same as a port does.



From what I have seen sos far the wall thickness of the N/A engine is about 3mm. I think it can be bored out a bit. The aux ports are on the outside of the plates anyway so if you cut through... Epoxy 'em shut!



Well thats what I would do anyway.
