'91 cams and ECU - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have a '97 240sx, and I got the S13 '91 Cams for a quick, cheap upgrade.

Because my car is an automatic, though, i started collecting parts for a 5spd swap. If i use a '91 5-spd ECU, will that negate the advantage gained from the more aggresive '91 Cams? I am not doing the double exhaust cam, just straight '91 intake/exhaust cam.

It is my understanding that '91 cams were more aggressive, but had a crappy ECU, where the S14 had the more aggresive ECU, and the crappier cams...

So putting the '91 cams and ecu would result in no net gain on an S14...

You can't use the 91 ecu

OBI vs OBII

Thats what i thought. Flywheel from '91 KA should still be good right?

Kid Zelda · 10-05-2003, 08:28 PM

Yup, flywheel is ok

What else is totally interchangeable? Tranny itself is fine i know, except maybe a bolt or two?

Clutch pedal, master cyl, slave cyl, drive shaft?

Drive shaft = NO
Clutch slave cyl = YES

Clutch pedal & Clutch Master cyl , it will fit and work .. not sure if you'll into any problems

Cool, i potential deal for the clutch stuff for $20, i might as well swoop on it then. Thanks.
