240sx perf.

[shming123]

could someone please tell me what are really good performance parts/manufacturers for the 95-98 240sx?? like who makes good cams, headers, catback exhaust?? who makes the absolute best...and also, how good the the differentials and trannys hold up to abuse?

this should probably be moved to the chat forum

These are some that I know of that are available for the s14:

cams - JWT has some. try contacting them to get more info
headers - Hot Shot, GReddy
catback exhaust - many but common ones are-
a. Apexi N1 dual and single,
b. HKS has a bunch but if NA then I heard
the Hiper is pretty good.
c. 5zigen fireball - has both turbo and NA
application I think
d. GReddy has a bunch

These are just some, I'm usre if you look around you may find more.

cool but as for headers, i was going to get greddy, but then i keep hearing that hotshot are better, but they make your check engine light go on..???

[S14 Drgn]

personally speaking, I haven't had any engine lights come on after installing my hot shot headers, and I've had these headers for a while now. Maybe its a certain setup that causes that, I'm not sure though.

Wasn't it the older HotShot design that did that?... but now since they've redesigned things I think the check engine light issues are gone.

[240racer]

how are four tubes welded together going to make your engine light go on?? somebody explain this to me. I have a custom manifold that I made myself and my engine light isn't on

[dragon240sx]

If I remember correctly the old HotShot design was a two piece that removed the first cat. converter and it might have changed the location of one of the O2 sensors and that's what caused the light to go off...not the header itself but the fact the computer didn't like the emissions equipment being changed...I also think the issue was only with the 95's or 96's and up because of the introduction of OBDII emissions programming in the computer.

correct... the hotshot header replaced the cat. the OBDII cars also have a second o2 sensor after the cat which will trip the light. not sure as to how to correct this, but it doesnt change any fuel mapping at WOT so I never pursued a fix
