I've just started my RB26/30 build and i'm looking for advice if its worthwhile enlarging the sump and adding the rear head drain.
The engine is primarily a street engine with very occasional 1/4 mile and track use. I plan to limit the revs to 8250-8500rpm. I already have sump baffles, oil restrictor and a N1 oil pump, and a large oil cooler. I was going to add the sump and head drain but now i think the money could be best spent on other things.....HELP
