Hi guys, I've been working on my s30 for a while now. at this point im looking for a big help on wiring. I have an l28et engine with harness. Engine was completely rebuilt and has a 3.0 stroker set up. I have decided to go with JW set up and have collected all the necessary parts that required by JW. Now, im in the processing of wiring between the engine and the z31 ecu. I did a research and have no luck of finding a good schematic for this set up. I have found an ecu diagram for a 240sx but not for the z31 n/a auto trans. If any one have done this set up, please help by sharing your knowledge would be greatly appreciated. I have a 1989 n/a auto trans ecu, s130 wiring harness, ford Maf sensor, electric ignition, 550 fuel injectors.

Hi everyone, I have my 280z hub axles welded a few days ago but thinking to go for aluminum adaptor. Looking for some opinions which one is a better way in the long run. Thanks! Kevin,

JSM, Which manual should i look for? I saw a few on ebay but they are cover from 84-88 model. Which mean all z31 ecu are the same? If i purchase a manual. Does it include the ECU diagram in it? Thank!

SleeperZ, Which pin on the ECU that will control the ignitor? I have MSD 6a installed. Thanks!

Hi everyone, Im a little confused with the wiring pinout and looking for help. I have a 1987 auto ECU that need to wiring with zx harness. I have read a lot of thread of how to wiring it but didnt see for a 1987 model. Here is my questions: 1. Are they all z31 ecu the same pin out? If not, where can i get a diagram for a 1987? 2. According to this thread, what does it mean by the word "shielded"? http://www.xenonz31.com/computerpinout.html 3. Do i need to hook up a TACH from ignitor to the ECU for fuel management (manage fuel injectors)? Million thanks for any comments and links. Kevin,

Can anyone please linked me some diagram of how to install the boost gauge? I know it is a simple job but would like to make sure i did it right at first start. I have an Autometter boost gauge. Where to hook up the hose to? Thanks everyone!

Thanks Z-ya.

Hi guys, Im in the middle of setting up E12-80 dizzy with MSD 6A. After gone through this post, im confuse with deciding which dizzy to use. I have both dizzy, turbo and e12-80. I will be using z31 ECU with 280zx wiring harness. Im going with JimWolf setup. Can you guys give me a good idea of using the 280z turbo dizzy? I have already installed the e12-80 to the MSD but still not sure if i would need to make any connections to the ECU? Please help to walk me through this since i have never done this. Thanks and appreciated!

Hi everyone, I'm looking for help on how to install the MSD 6 into a turbo distr or E12-80 distr. i basically follow the msd manual wiring all the neccesary wires. I have both of distr set up, either one work should be fine for me. I know the E12-80 distr is a point distr. i currently have the 240z wiring harness out of the car for troubleshooting for short issues. My set up; -l28et -z31 ECU -low impetance injectors -280zx stock harness -MSD 6 ignition module -MSD blaster 2 -E12-80 distr Here are my main questions: 1- if i use the E12-80, i know the C terminal is going to the MSD input (white). Do i also need to loop this to the ECU too? If so, what pin should i connect it to? 2- if i use the turbo distr, which terminal is the output signal to the MSD? And how to wire them correctly? 3- is the turbo distr also a Point trigger? 4- who is tell the ECU to open the injectors? Thanks for all the input in advance! Kevin,

Sorry, i meant how much should be take off for free-play. Not add in.

Hi everyone, Can someone please give me some instructions of how to add in free-play length for order a custom half shaft? For example: if my measurement from end to end is 14" driver side and 11" passenger side, how much should add in for free-play? I'm in the process of r230 conversion. The machine shop wants $400 to shorten and respline the two r230 half shafts. Thanks for any comments! Kevin,

Hi everyone, It's been a while i haven't have time to post new topics. Was busy working on my s30 project. Im looking for some help to determind how much of space for free-play if i want to shortten the cv shaft? My measurments are 12.7/8" from adapter flange to the halfshaft. What is the final length should it be? Thanks for any inputs. Kevin,

Thanks for the answers SleeperZ. I've just got my S30 suspensions done. Now moving to engine wiring. Hope can get some helps later if i got stuck.

Hi everyone, It's a long story since the day I've started to jump into this route. I first was trying to do engine swap to my 280zx but then get some advised to go with 240z. That have me changed to go with 240z and working with it. I am now at the last stage of doing engine swap on to my s30. I have a 1985 z31 turbo ECU and wiring harness that came with the L28ET when i bought. I've pretty much done all the other stuff and now looking for a serious help of setting up the ECU. I have a few questions that not sure what to do since i've got confused with many different answers on the internet research. Here is my problems: 1. What is the minimum fuel delivery should i use for my set up? 2. Do i need to remapping the ECU to run a 550cc fuel injector? 3. If i run stock z31 ECU, do i need to do any modification on wiring? Here is my set up: -89mm pistons -Stock fuel injectors -Borg warner T5 tranny -T3/T4 ball bearing turbo -Stock exhaust manifold -50mm wastegate -3" exhaust system I know there's some threads have already posted some where but please post it here is greatly appreciated since I don't want to get more confuse of reading else where. Please any comments would be useful and thankful for walking me through these problems. Cheers,!!!

Hi everyone, I'm looking to finish my parts collecting and start working on my project. I'm looking for an LSD to swap out the stock one. I have read a few posts about the LSD but still don't know which one will fit best. If you have one please let me know. Thanks! Kevin, 7l4-39l-l860

Hi everyone, I'm looking for a T5 manual transmission for my 280zx project. If you have one please let me know how much. I live in southern california. Thanks! Kevin, 714-39l-l860

Hi guys, After i have collected all necessary parts to stroke my engine. Now, i'm ready to hire someone to reassembly the engine back together. I've took the engine apart piece by piece and have the block bored. Pistons and piston rods, and the head are assembled. As i am now so busy don't have time to continue with the works. I would need some one to finish all the rest to make the engine run. All the parts are ready to assemble. I live in Garden Grove, CA. So, if you know some one that you can recommend or you can do it. Please help me out. You can call me at 714-583-0253 or email to logoleaf@gmail.com Thanks in advanced!

Hi everyone, I'm looking for a 5spd transmission for my L28ET engine. I'm located in socal. Let me know if you have one for sell. logoleaf@gmail.com thanks!

This is my first project. The problem is my english is not that good and kinda hard for me to understand the things people named it. For example: we used to call those main bearing as a washer or a ring for crankshaft in my country. That's how it means in our language for amateurs. If i have the repair manual i shouldn't posted for help. But i really appreciated for all of your work trying to help me. Here is what i've just done today: -I've torqued the crankshaft and trying to turn by hand to check. It's turn it tighten about 15% of round. I'm not sure if that's the way it could be? I've had the crankshaft balanced at machine shop 2 months ago. -Next i'm looking for a tool to take the thing that holds the rod & piston to put them on my new piston set. Can anyone post me some links to check how to do that part? Thanks in advance to all members here.

Thanks alot guys. This help me a lot. I'm trying to put my L28ET back together. Hopefully i have it done before summer is coming.

Hi guys, I've accidently lost the things between the block and crankshaft of my 83 280zx. Please see the photo below. I need to know what is it call? If you know or you have one please let me know. Thank you!

I'm looking to upgrade my 280zx wheels. I think i will go with a max size that best fits for the rear wheels. I love to have it looks fatter but don't know how to figure the size. If any one can help with sizing that would greatly appreciated. If you have a set that want to sell. Please send me your pics. Thanks!
