Guest JAMIE T Posted September 15, 2003 Share Posted September 15, 2003 Guys, I just picked up my L28ET from a guy who sells a bunch of this stuff. I got the harness, AFM, ECU, and the complete engine, plus an assortment of heat sheilds, and assorted BS. The ECU looks like a junk yard unit, and I wanted to make sure it is in fact a turbo ECU. The yellow label has the following numbers. A18-602 043 and 1X21 This is SUPPOSED to be from a '82 ZXT. Also, the engine does not have the distributer. He is supposed to be shipping it to me. How can I determine if I'm getting the correct part? I know the '81 and '82-'83 parts are differant. What should I look for on the engine to determine if IT is in fact a '82 engine? I got this stuff from "H1Shutterbug" off the ZCar.com forum. I paid him in full back in January, I am just now getting my stuff. Take that for what it is worth.

vashonz Posted September 16, 2003 Share Posted September 16, 2003 This is the tag that was on my extra ecu. http://viewyachts.com/chris/yellowz/wireecu/DSCN0077.JPG It was from an '81 turbo, it works (I checked it). The later distributor has a wire coming out of it and is much larger than the '81 unit. The '81 is essentially a shaft connected to the rotor arm, no timing unit, no electronics.

fl327 Posted September 16, 2003 Share Posted September 16, 2003 im not up on my serial numbers and codes for ecu, but I know that if its green, its from an auto, black is from manual. unless ive pulled it myself, ive never been able to trace down where ecu is from.

Guest JAMIE T Posted September 16, 2003 Share Posted September 16, 2003 Thanks guys. The ECU IS green. The tag does NOT designate L28 though. Nothing is written in that slot. Please, if anyone has numbers documented, post'em here. Before this deal gets sour on me, I want to be able to make sure I get the right parts from this guy.

fl327 Posted September 16, 2003 Share Posted September 16, 2003 75-78 ecu is only one big molex plug port my turbo ecus have three molex ports the easiest way to find out is to find someone with a zxt and swap ecus and see if it fires up, if it wont even plug in, its wrong. 81-83 zxt all have same molex ports.

Guest JAMIE T Posted September 17, 2003 Share Posted September 17, 2003 No one in my area has a ZXT, or swap. The ECU does have 3 molex connectors on it. Someone has to have identification numbers on these things! FL327, can you check the numbers on all of your ECU's? Write'm down and post'em. Maybe we can provide a service to other Zcar turbo swappers by posting all the ECU info we can wrangle. Quote Link to comment Share on other sites More sharing options...
fl327 Posted September 17, 2003 Share Posted September 17, 2003 here are two i have with me, others are in storage 83zxt 5speed ecu A 18-601 042 stamped 2705 81zxt auto A18-000-040k stamped 1125 it is green and has a nissan remanufactured ecu sticker on it 8) ill have another one for you later, its still in the car.

Guest JAMIE T Posted September 17, 2003 Share Posted September 17, 2003 Thanks FL327, I'm feeling a little hopeful now. Once we have all the numbers we can get, maybe the moderators can post a sticky with all of them listed. Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted September 17, 2003 Share Posted September 17, 2003 I"m 99% positive that only the turbo ECU's have three plug ports on them, my '81 N/A ZX only had one long port, as have all N/A cars I've seen that I've noticed the ECU on. My turbo ECU also has 3 connectors on it. From what I understand, all three years of turbo ECU should be compatible. For instance, I'm running an '82 ecu with an '82 harness, on an '81 motor with '81 distributor (CAS mounted on the crank pulley). I have a friend who's running an '81 ECU with '83 distributor... so dont worry too much about the year of the ECU. I think the only thing that MIGHT matter for compatibility is that the wiring harness be the same year but honestly I even doubt that... I also know that you dont want an '81 wiring harness, apparently they are much more complex than '82-83. Quote Link to comment Share on other sites More sharing options...
Guest JAMIE T Posted September 17, 2003 Share Posted September 17, 2003 Bastaad, thanks for the help. I'm pretty sure the harness is of '82 descent. It is real simple looking. Also, there is nothing near or around the crank pulley, so, I'm pretty convinced it IS an '82 engine. Now, I just need to make sure he sends me the correct distributer. I just cut the "fat"(AC comp., PS unit, etc... This engine is from an automatic, so it has the oil cooler fittings, but he forgot the lines and cooler. I'm definatly going to need a spacer on the turbo flange to fit the compressor I got. Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted September 17, 2003 Share Posted September 17, 2003 the most easily spottable sign of an '81 engine is that it has a thin toothed gear mounted behind the crank pulley. One thing you may want to do, if indeed it is an auto engine... there should be a vacuum hose that goes from the bottom of the throttle body to the intake manifold. This connection keeps your throttle open briefly between shifts, from what I understand it's to keep the revs up while the auto trans is shifting. If your switching to a manual trans this can be problematic though as the revs stay up between shifts and will cause your shifts to be rough when you re-engage the clutch. If you have this problem just disconnect the hose and be sure to block both ports as leaving either open will result in a vacuum leak.
