I have found that the '99-'00 Blackbird has a 43psi FPR that looks just like 6th gen VFR. I know you can buy a 42psi unit from Turbo City, but this is half the cost and availible at the local dealer. By the way, '01 and newer birds have 50psi units, reportedly to fix low speed problems. I have never seen, in person the regulator in person, just pictures. If any of you have, please give up you opinion.
Late post, but did you ever try to fit this and what were the results? I am looking to do the same thing and hoping to get some feedback from someone who has already tried it. Thank you.
