Since I just installed the isis manifold on my car I will put my .02 in... For the money it is good. That being said, it fit like shit. I had to reem out every hole in order just to get it to go over the studs. And I don't mean a little, I am actually a little concerned with how much material I had to remove. Looks like the jig they are using is off, or maybe I just got one of the bad ones in the bunch. I have installed many different types of exh manifold on sr20's and I have never had to do that to any other manifold.
Aside from the fitment I have no complaints. Quality of the material and welds appear to be good. Once on teh engine there were no probelms fitment wise anywhere else. Plenty of clearance from bmc, steering shaft etc.
Even with the fitment problems I would recommend it to others as the closest "name brand" manifold is at least twice as much $, but like in anything else in life, you get what you pay for.
ok black guy what can u tell me about this fitment issue with the manni on sr's?
