MJLamberson Posted September 6, 2008 Share Posted September 6, 2008 I am about to rewire my turbo 280z to run off an 83zxt ECU, Most of the process sounds easy enough and I am familiar with the wiring harness and have done plenty of searching. Right now my only question is this: On the 83 wiring harness there is a connection for the Crank angle sensor, I was told on the 83s that this sensor was in the distributor, now on my engine I am useing the distributor off my 77, Am I going to need to put in a 83 distributor or can I buy and put the sensor in what I have now? I dont really understand this one area of the conversion so ANY info or pics of said sensor would be wonderful. Thanks again guys. -Michael Quote Link to comment Share on other sites More sharing options...
Challenger Posted September 6, 2008 Share Posted September 6, 2008 My 83 turbo dist. has a 4 prong circlular connection that comes out of the shaft below the rotor. Im guessing thats the sensor. Quote Link to comment Share on other sites More sharing options...
JSM Posted September 6, 2008 Share Posted September 6, 2008 Your modifying your existing 77 harness or using a Zxt harness? If zxt harness find a zxt distributor. Quote Link to comment Share on other sites More sharing options...
hughdogz Posted September 6, 2008 Share Posted September 6, 2008 The '82-83 turbo distributors use an Optical cam angle sensor, while the n/a's are induction. The turbo ECU will be expecting a digital signal, not an analog. The optical sensor uses the "chopper wheel" which will output a square wave signal (digital = on, off, on, off). The n/a will be a sinusoidal-waveform (analog, like an ocean wave = rising, falling, rising, falling). I'm pretty sure you'd need a ZXT distributor if it is '82-83 turbo ECU (or the '81 crank damper & CAS if the turbo ECU is an '81). Hope this helps MJ...

MJLamberson Posted September 6, 2008 Author Share Posted September 6, 2008 Well there goes another 250$... at least that will be all I need to get it running... oh it better be all I need to get it running... Maybe I will run out to the pick n pull, would a NA 83zx one work? I figure a crank angle sensor is a crank angle sensor right? Quote Link to comment Share on other sites More sharing options...
hughdogz Posted September 6, 2008 Share Posted September 6, 2008 Well there goes another 250$... Not necessarily, you may be able to find a ZXT distributor & ignitor for from someone on here for less than that. Maybe I will run out to the pick n pull, would a NA 83zx one work? The n/a uses an E12-80 ignition module, but the turbo has a different one located next to the coil. Make sure you have one of those too. I figure a crank angle sensor is a crank angle sensor right? Yeah, just like a piston is a piston and and an ECU is an ECU. Seriously...you don't have much further to go now! Quote Link to comment Share on other sites More sharing options...
