  1. What year 240sx trans

    74 260z with r200 diff and l28et. I want to do the 240sx transmission conversion. My friend has a donor transmission but its from a dual cam ka24 240sx. Will this work or doe only the single cam 240sx transmission work. Ive read some mixed info. As long as there is no difference aside from the bellhousing then its a go. Thankyou
  2. Thoughts on 280zx Turbo Parts Car?

    Hey everyone! So I'm planning on picking up this 280zx Turbo next week. I want to use the engine, wiring harness, etc. for a turbo build for my 260z and I figured it'd be easier to buy the whole car than to piece everything together separately. Would anything else off this car be useful to me? The only thing is it's an automatic but I could find a 5 speed from an N/A? He's asking $1500, I'll post a link below and would love to hear what you think it's worth. Thanks! https://myrtlebeach.craigslist.org/cto/d/1982-datsun-nissan-280-zx/6377046535.html -Austin
  3. ISO L28ET Stock Injectors

    Does anyone have a set for sale? I can't afford to buy refurbished ones. I have an ultrasonic cleaner and test bench so it's okay if they haven't been cleaned. Thanks!
  4. Finally Picked Up My S30

    Hello everyone, I've been a Nissan fanboy since I picked up my first 09 Nismo 370Z. I've been racing that ever since and eagerly eyeing an S30. I am a NASA National Instructor and compete in a wide variety of events in a wide variety of cars. I've earned trophies with NASA, SCCA, Chumpcar, completed the One Lap of America, and more. I'm sure you care much more about my Datsuns. Picked this up for a steal to give it a good home: my garage. It is a 1977 280Z with the L28ET from an 83 ZX. All done by the previous, previous owner. Originally from the west coast, it has very little rust after 3 years around Washington D.C.
  5. Can anyone tell me which vac hose to tap for a mechanical boost gauge on an L28ET? I took a pic. Bonus if you can draw an arrow pointing to a specific hose!
  6. Looking for l28et

    Hello, I’m looking for l28et with p90 head. Optionaly with the Borg Warner T5 and r200 diff. I have complete stock 260z and would like to go turbo. Best regards, Mark
  7. So about a week ago my car started to have issues when it got up to temp. It would originally start, idle, and run fine, but after the car began to get warm it would lean out like crazy (have a wideband installed) and there would be no response when throttle was applied under load. It did this for a few days until it decided to completely die on my way home from the gym. After a few minutes the car would start and idle lean on the side of the road, but then die immediately with any throttle (not under load). The engine is from a 1983 280zx turbo. After a little bit of research I'm wondering if it is my Crank Angle Sensor in my distributor, but I'm still very confused. I don't think it's a wet Throttle Position Sensor because I had that problem recently and I removed it/dried it out and the car ran fine. Also the symptoms are different due to not even idling rather than failing at 2000rpm. Short video with symptoms: https://streamable.com/nn9ls
  8. L28ET Out / L24 In

    I am swapping out my L28et for a rebuilt L24 w/ triple webers. A head-scratcher for most but, nonetheless, the direction I want to go with the car. Looking for any prior experience/guidance on making the swap back to NA. I did some searching but no luck. The turbo set up is out of an 83 ZXT. Swap was done in the early 2000s by a shop in Illinois. Not particularly comfortable with electrics so, the wiring harness is of particular concern.
  9. How is it going my Z fam. I am have a issue on my L28et i did not have with my last setup. And was wonder if I could pick your brains for some thoughts. The car has a bad stumble on acceleration from any speed. It leans out but it always recovers after a few seconds. This is a issue on light throttle takeoffs from stop lights and in stop and go traffic. The car has even died on me a few time due to this issue. Any help would be much appreciated! I have attached a video of issue from a few days ago.

  10. Help me value 280z with L28ET swap

    Hey all, Recently looking at getting into older Z's. Was gonna do an L28ET swap as my first foray into engine swapping (given its apparent simplicity) but if I can avoid it I would rather do that and focus on the more "fun" parts for me (suspension, bodywork). I found a 1978 280z 5 speed with '82 zx turbo motor and oil cooler for sale locally. Guy has owned it since 2004, did the swap himself, and driven for ~3k miles a year. It is right at 100k miles and garaged when not in use. Looks like pretty much stock everything else (suspension, driveline, body, interior, etc.) Body is mostly straight but has a few quarter-sized holes as well as 2-3 rust spots spots. He is asking $9,995, what do you guys think is fair?
  11. Hey guys, quick question. I have an L28ET in my car (with MS) and I am upgrading to supra injectors, the 7mgte ones. From what i have researched, they are 440cc and work with a pallnet 11mm rail, which I just ordered from him. I am confused as to what impedance I need. Here's what I currently believe to be true: L28ET injectors are low impedance, and require the resistor pack to make them work. 7M-GTE injectors are also low impedance, and should be used in my system with my current resistor pack. However, all the 7m-gte injectors on eBay (don't worry, not ordering from there) are listed as high impedance. I just don't want to order the wrong injectors, is there anyone who is running the 440cc injectors on an L28ET who can chime in to what their wiring system is? I don't want to order them before I at least have some answer.....There is so much weird and confusing information out there about this stuff. Thanks in advance!
  12. Want to get rid of the OEM fuel rail. Please let me know if you have fuel rails for the stock injectors for a L28et. Closer to NJ the better but will pay for shipping if price makes sense.
  13. Need a map to get it running

    Hello. Im fairly new to the forum but i need help with my megasquirt. I restored and engine swapped my 260z and its finally time to get her running. I bought and assembled my megasquirt. I also made my own wiring harness with DIY's harness. Im almost positive i havnt made any mistakes along the way however the actual tuning part of the ms2 boggles my mind and i have no idea what im doing. I need a map that i can get my car running on for now. It is a stock block with a fresh rebuild, p90 head,stock distributor with DIY' trigger wheel. stock turbo injectors, stock turbo and psi, 240sx throttle body and tps, walbro 255lph inline fuel pump, i have bypassed the fuel pressure regulator for now as it wasnt allowing fuel though. I have messed arounf with some other maps i found on the forum but none of them are perfect. I want to say my firmware is the latest for ms2 extra. i belive i have the pcb 3.0. i will atatch the tune i found and am looking thru. Anything helps thankyou. CurrentTune.zip
  14. washed block before teardown

    From the album L28et Rebuild

  15. My motor has always had a lite bit of a rattle but it has gotten worse to the point it scares me. Noise comes from the top of the front cover. Car runs great. Does this soundick like an upper guide or the lower tensioner?
  16. Hello i am new to this forum but i hope to get some opinions. I have fully restored my 260z and it is mostly stock, i recently bought and rebuilt a l28et. now that the engine is done i am moving to the wiring and i come to realise that i do not have the proper wiring harness. The guy i got the engine from gave me everything he had. by the looks of it i have a 82 l28 ecu and harness, a later 70's wiring harness slightly cut up, and the correct 82 l28et ecu. Should i bother with the stock ECCS and make a harness or should i buy a megasquirt. The megasquirt is tempting but im one to save a dollar. the megasquirt seems very complicated for my liking. if anyone has an 82 l28et harness i need it. My hope is to finish this swap before april. thankyou
  17. In need of a complete, working 1982/1983 Datsun 280ZX Turbo distributor/ignitor. I am located in 85120 I'm willing to hvw one shipped I need ASAP thank you.
  18. l28et vems standalone

    Hello everyone my name is luke and i have a 74 Datsun 260z l28et project that I'm going to be documenting my progress on . I swapped an 81 l28et into it and am currently doing a Vems v3.7 install. I want to make a thorough write up to make standalone install on these motors (or in general) easy to understand. In my setup my motor is mostly stock except for the Vems, a straight exhaust and the common deletes (egr,ac, etc...) In this write up I will cover the basic aspects of engine management. Crank/cam sensors, injectors, ignition, map sensor, coolant temp sensor, TPS, and O2/egt sensor CRANK SENSOR- for my crank sensor I will experiment with using the stock 81 l28et toothed CAS wheel (90 tooth) with a retrofit VR sensor as this is what my Vems is configured for. the setup picks up a signal on cranking but i have not yet ran the car on it. INJECTORS- the injectors I am using are the stock l28et injectors. These are low impedance (ohm) and there are 2 ways to drive these injectors. This is general and applies to most if not all ECU's from MS to Vems to Electromotive. The first and more preferred way to drive low z injectors is PWM (pulse width modulation) this modulates current during injector hold (open) time to prevent injectors from overheating (with this method the you don't use inline resistors). The second method which I am doing is to run inline resistors on every injector and drive them as you would normal high z injectors. L28et injectors are approximately 2.2-2.3 ohms and I will be running a 50w 6ohm heatsink resistor inline on each injector. I will be putting the resistors on the ground(computer) side of the injectors . They will be mounted in the car near the ECU. Injectors are wired independently for sequential injection. TPS- in my setup I use a GM TPS 5v 3 wire. most TPS that are continuous not switch type will work. The stock one i believe is a 3 position switch. this will not work. I made 2 small brackets to mount it to the l28et throttle body. IAT- for my intake air temperature sensor I also used a GM IAT. It may be tricky to find a good spot to mount it keep in mind it has to be in the manifold area (after the turbo). MAP- for my manifold air pressure sensor I simply used the supplied Vems internal sensor. My pre assembled Vems unit has an internal 3-bar MAP sensor. There is a vacuum hose output on the ECU that is ran to a port on the intake manifold. Very convenient and simple. IGNITION- for my ignition setup I will be using a single coil ran through the stock dizzy. I will experiment with using the internal Vems igniter and using the stock l28et coil/igniter. Coil has +batt on one side and the other ground side goes right in the computer (coil-0) this is the simplest setup. In the future I plan on goin coil on plug or do a 3 coil setup. If you are doing a coil on plug setup you have to remember it's going to be waste spark Unless you have a cam position sensor (which simply indexes whether the motor is on exhaust or compression stroke). CTS- I have not decided on what coolant temp sensor I'm going to use Yet. The stock one is a 1 wire and I believe is useless. I believe GM sensors have the same size/thread. I will experiment with CTS and let you guys know what fits into my thermostat housing. O2 - For the oxygen sensor I will remove the old 1 wire sensor which is also useless and use a Bosch Wideband sensor. i believe The particular Bosch o2 is somewhat specific to Vems and I believe can even be used from any Audi/vw 1.8t. Wideband O2 sensors are essential in tuning a car. Vems have built in Wideband controllers so all I will need is the sensor which is under 100$. please correct me if any of my information is wrong. i anticipate to do the first start in about 1-2 weeks. i will continue to keep everyone updated and hopefully post some pictures soon.
  19. Decided to go a different route with my L28ET build so I am selling off my Turbonetics turbo i never got to use. It is their TNX line of turbos.

Retail price for the turbo with housing is $2144.98 before shipping My asking price is $1500obo, Free shipping to any of the 48 states
  20. I have been working on resurrecting my '72 240z w/ l28et conversion. In the past two years the car has come a long way. Due to lack of time and/or lack of expertise I am hoping someone can point me in the right direction on the following items remaining on my restoration to-do list: 1. Installation of interior control panel 2. Install of radio and speakers 3. Install of sound deadening 4. Fender roll or install of fender flares 5. Troubleshoot ignition/fuel issue (fairly certain it's a bad TPS) I'm in north/central jersey. If anyone has a trustworthy and reasonably priced mechanic that can do the work, please let me know.
  21. resto-mod 240z best swap

    I am looking to get a 240z or 260z from 1970-73' and would like to do a complete resto-mod. I am limited on knowledge and experience as well as tools and space. I would like this car to have the reliability of a daily driver, though it will most likely be used as a weekend car. I am looking for a z with minimal rust that runs, i would like to upgrade the suspension, fix any body issues and interior issues, then finally swap the engine. What would be my best option for an engine swap? Things I am looking for in this car. -Street legal in New York -200-300hp -very reliable -preferably na but not opposed to turbo if it is more reliable - Have it professionally done - quick linear throttle response I have been doing a lot of research on swaps but could not come to a conclusion. Which engine/tranny combo would be best for my goals and what is a ballpark price range i would be looking at. I understand the price could vary greatly, but considering I need to buy the engine and all components necessary for the swap and pay a professional to install it. Thanks,
  22. Hi everyone I'm currently doing a 81 l28et (all stock) swap into my 74 260z. My harness was missing the 6 pin ignition harness. I wired the correct yellow/white stripe wire (3) to my ignitor. Other prong on ignitor has its own switched 12v. The yellow wire (2) on the harness side has switched 12v. And finally the supposedly black ground wire (3) on my harness is cut and i can not for the life of me find the wire . If someone can tell me where this wire goes or what prong on the computer plug it connects to. Thank you 74 260z 73 240z
