So I've recently picked up a rnn14 gtir motor that's in decent shape aside from a spun bearing on the main crank (guessing for a second time unless the own bearings came with 5 oiling holes). Since I'm assuming one of the original owners did the usual drift to death I'm replacing all the main bearings.
I've measured the crank X and Y axis. As well as measured the block with the caps and girdle torqued down with the bearings in and with the bearings out.
My problem is that even with the FSM math it still leaves me in the dark with actually selecting a size. (Probably going ACL or king) as this isn't going to be a high boost/ HP rebuild but will see quite a bit of time in the high end rev range in short spurts.
Anyone know a good place to start? Or just order a set with slightly less oil clearance and hope for the best on a plasti gauge double check? Access to parts up here in Ontario is pretty limited so don't really want to spend a fortune on ordering a bunch of different ones.
