The Cosworth tuning is less lary than it seems and the ECU is all pre-packaged. Ditch the Mazda gearbox and keep the Elite unit offered.

Only adjustment is prop length which is an easy enough job and not scary.

A decent CR HD race box and you’ll be wondering why use a road box...??

As a complete integrated unit - it’s a good price (no affiliation with seller btw).
