go to sean morris blog. you have to look under advanced notes. he tells you why the early rb26 have an oil pump problem. also explains difference b/w N1 and Nismo oil pumps. Also gives a heads up about RBs creating alot of blow-by. Sean IMO pretty much is the most knowledgeable non-japanese guy in the US that knows the RB-powerplant.
I read some of it. It stated to run like 2KG more upfront of spring rate for street. ie 12/10 street. and for track ie r-compounds or DOT slicks an even rate like 10/10 or 12/12
