Guest Cronic Posted October 6, 2004 Share Posted October 6, 2004 Is this an upgrade for my 280zx? It is the non-egr intake, and appears pretty similar to mine. I'd like to port it out and see if I can pick up any gains from it. What do you guys think? Quote Link to comment Share on other sites More sharing options...

Drax240z Posted October 6, 2004 Share Posted October 6, 2004 I doubt you'll see any performance gains in stock form. Runners are the same size, as is plenum, etc. Some later manifolds plenum tapers down towards cylinders 5 & 6 to increase air velocity which the earlier ones do not. The biggest difference is just aesthetics really. The N42 is a much nicer namifold to start with if you are trying to clean up the look of your engine.

Guest Cronic Posted October 8, 2004 Share Posted October 8, 2004 I think Im gonna cut her open, see how the insides look, and port the FSCK out of it. Just to see what it'll do. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted October 8, 2004 Share Posted October 8, 2004 You could send it off to be extrude honed... I wonder if anyone has done that with one of these manifolds before. I suspect the gains would be rather huge. Quote Link to comment Share on other sites More sharing options...
