Gearbox wise there is a golf/audi box conversion in the pipeline.
The boxes on the 172 are poor and the diffs for them are expensive, thats the reason I went B18 rather than F4R for my choice of engine to turbo for my Mk1.
Scoff from efiparts you mean?The black r5 in the esc is running that gearbox conversion.
With excellent results it looks.
