gbabcock Posted January 20, 2009 Share Posted January 20, 2009 The hybrid forums are new to me, so hello all. Basically, I just lucked out and picked up a L28et out of an '83 for next to nothing. I've currently got a '73 240z that I can put it in, but seeing as I've already got a 260z that I've been doing an LT1 swap with which is sucking away all my money, if I do this one, I'm going to do it on a low budget. What are the recommended upgrades that I should do and, should I put in the extra 200 and get a t5 to go with it, or just swap on the 4speed that is in the car now? I don't have a wiring harness for the 280zx, but I have one off a 280z - would it work? Also, what are the ideal ECUs, etc. should I use? I've heard that some stuff off 300zx work well. Any help or ideas would be great. Quote Link to comment Share on other sites More sharing options...

Daeron Posted January 23, 2009 Share Posted January 23, 2009 Like he said, for specific answers you need to search and spend several hours reading over material that sounds like the same story time and time again.. the value of this forum is in repetition, and trying to benefit from mistakes others have made before you. Nevertheless, it is a discussion forum, and crying "search" sorta kills that side of it, so I will give you a few points to help straighten you out on your path, and maybe answer a few questions.

Any help or ideas would be great. Now, First let me say that while I own and drove a stock EFI 280Z for four years, my old man and uncle have driven various 240Zs for decades, my dad had an 83 turbo stock etc etc.. I have NEVER done a turbo swap, so understand that what I say to you is all "hearsay" or information picked up through the internet rather than firsthand. (standard disclaimer, yanno) As far as simple, without getting the 280ZXT wiring harness and ECU and complete longblock with manifolds etc.. you've got a task ahead of you. the 280Z harness can certainly be used (I think some issues will arise in the distributor section) but I do not know what you are going to do regarding ECU.. I *think* the turbo ECU might plug in in place of the nonturbo but I really am not sure. I know I have heard of people getting a turbo running on non-turbo ECU, but its shakey at best.. For $1000 (probly less, possibly more like 600-700) you could get a megasquirt kit (with other bits needed) and a wiring harness from them that you could use to supplement the 240 wiring harness and make it work. Regarding the transmission, the T5 may not be such a no-brainer.. but having a fourspeed just plain stinks, let me tell you... Keep your eyes peeled for a five speed, look at the options such as 240SX swap in (not too too difficult) and make your mind up "later." The four speed is surely good enough to get the car up and driving; it won't explode on you unless its already on its last legs. These boxes are pretty darned solid, all things considered. If you are good with wiring diagrams, google the terms xenons30 and xenons130 for websites that have links to download the various years' FSMs, and study some wiring schematics. See what you have to deal with. Go to DIYAutotune's website (advertised heavily here) and look at the megasquirt kits and wiring harnesses and FAQs and see what you want to do. A MS kit will make it easy to make power with the turbo motor; you could use that to build a car that has 300 or so horsepower laying in wait, but has a "girlfriend mode" to drive around town with... or just set it up in "girlfriend mode" for good. the 300ZX stuff is really involved, and super cool... but you've got to be motivated, inventive, and pretty much a total geek to really want to do it (I want to because I love MAF for some reason I haven't quite explored fully) The research about the stock swap versus MS and all the other stickies should explain most of that to you well enough... in short, you have to take like, half of the EFI system from the 300ZX, and do some crazy stuff to make it work right... and in the end its still just basically, what Nissan would have sold if it still used the L28 as a power plant in the late 1980s with the level of tech they were using at the time.

MJLamberson Posted January 23, 2009 Share Posted January 23, 2009 Your engine is out of an 83 so the CAS is on the dizzy, meaning you need an 83 zxt wiring harness and ECU, The turbo ECU does not plug into the NA harness. You really do need to search though, sooo many people have done the swap... Quote Link to comment Share on other sites More sharing options...
