I have been told this is the place to go to get this question answered because no one has done it (and I dont blame them because it's not an increase of any sort, just required because that's all i have lying around)
wondering if there will be an issue switching a RR lowport 01' sentra head onto a 91 sentra non RR highport block. my block is shot and i'd like to swap the head over to my old reliable recently rebuilt block.
I've read a ton about how the blocks are the same on all sr's except the g20(oilpan issue) - but nothing about whether a RR lowport block and a non RR highport block are the same. (it seems the oil filter's in a different place but the internals are the question)
my block is cracked, and i'm putting the rr head on a non rr engine. nothing having to do with realine or a ve etc. I've already done those things to my nx, and i'm simply doing this swap because i have a block already that isn't cracked. it's a reliability issue not a performance one.
