no dyno numbers yet, I am working on 2 rr motors, one is very similar to yours, except I don't have it tuned, I think the advantage with the uk primera is that you don't have the issues we have in usa with the 2000 through 2002 models that use a 32 pin ecu like the b15 guys do, no aftermarket support. so that's why I was considering doing an sfac for mild adjustments on my daily driver.
my second rr motor I am trying to replicate what some one from your side of the pond did, and that's drop sr16ve pistons in sr20de to jump up the compression and get a little more power from it, and that one I do plan on tuning correctly. when I get done ill post results, im going on 2 years with the project.
