The shop that did my cage has built countless cages for the cars running with the Hillclimb association and Rally America. We discussed a few options and then I just let him run with it.
Got a virgin PM6 ECU and A6 Valve cover for free from the guy at the tire shop because he liked the car so much. His only request was a smoke show. I obliged.
The current question is whether to rebuild the A6 head or buy the D15B vtec head for roughly the same cost but of unknown origins.
