i hate diesel engines, they sound weird and their reek is an anathema to since i stood many times behind my tank to warm me up in winter
but hey, many poeple are frozen, none of them perished of smell
i do tranny conversions, it's not too hard, but you need proper equipment (you sure have)
the pinions i have in stock (+11%)
for warranty reasons i modify only new gear boxes, so bearings and sealings are new and easy to disassemble
i advice you to take the bombardier radiator, it holds almost 2l more liquid
also the additional (diesel) oilcooler with fan is a good add-on (but hard to get, almost no diesels are stripped for pieces)
