Or you can always grab one off of a 300zx at pNp. Its probably the cheaper way to do it.

Hey guys, I have a similar question regarding my l28et swap. Is the fitting on the 240z tank big enough to supply fuel to the surge tank? I would drop the tank and have a welder weld bigger fittings, but its hard to find a welder who would actually do that.

Also curious about the supra injector seals!

Hahaha I honestly never thought of that option, thanks Cockerstar. Does anybody know where I might be able to pick some up for cheap? Can't justify paying MSA 54 bucks each.

I'm actually not too sure, I bought it from a guy in Stockton and it never occurred to me to ask him. But I been searching around for the pass few months with no luck. It fits in perfectly,so I never thought of it being from a different model. I initially thought it was the ones that MSA sells, but I noticed from the MSA pic that they might not have the ridge on the sides like the ones I have.

So I finally got my hands on some triple 40 Webers, but it had only came with 5 horns. Been searching around but I can't seem to find a replacement horn. Hopefully someone recognizes them, and is able to tell me where i might be able to buy another one. They're just a littler taller than 1 5/8. Thanks in advance.

interested!

I'm currently in the same situation, I'm trying to install a surge tank in the fuel system but I think the stock hard-line will be too small for my walbro. Does anyone have pics of their surge tank setup and location?

Hey guys, just shopping around for a LD28 crank, let me know if anyone has one laying around and how much you looking for it. Thanks!

I ran into the same problem trying to fit my 240sx tb to the manifold. Initially I was going to run the tb without spacer and just use a Lokar tb cable but then I realize the gap at the manifold after I cut the cooling passage on 240sx tb. I think before I had cut the cooling passage there w as just enough material on the tb to cover the space, but don't quote me on that. I ended up ordering a tb spacer after searching around for a solution, http://arizonazcar.com/inject.html sells one of the cleanest looking ones.

Sorry not to change the subject back, but when i did my l28et swap into my 73 the stock fan from my 81 wouldn't clear between the radiator. I know for a fact that they fit because i have seen several members with the same swap using the stock clutch fan, now I just wonder if I have reversed the motor mount or the rubber bushing on them are just going bad. When you guys swap the the l28et motor in, did you guys use the mounts off the l28et motor or did you guys use the same one off the car your swapping into?

Hey i'm actually doing the same manifold right now, its a pain trying to remove all the extra bits. I ended up cutting off the egr plenum too, theres just a few small ports at the bottom to weld up. but i was just wondering wha tool were you gonna use to shave it off? I'll post pic of mine once i get a chance.

I would go through and clean all your grounds and connectors,that was my biggest issue. I first had a bad ECU, then Ignitor so no spark, changed that, then no fuel, tested it with starter fluid ran for a little bit. then died. pulled my injector clips and found that it was all corroded so I cleaned that. still no start. Found bad ground, fixed that and it cranked right up. but the ECU light shouldn't turn off on crank, well at least mine didn't.

3:45pm The engine finally starts! I ended up using the dropping resistors, turns out the car just needed a little more loving. I soaked the bottom end of the injectors in fuel and cleaned them up a bit. Noticed on the ECCS that my TPS wasn't getting signal from time to time, found a loose bolt that grounded the sensor to the throttle. After i got the motor running I tried revving it a little bit, but each time the car would die from me touching the throttle until it warmed up anyways. After the car was warmed up, the throttle response was fine which seems a little weird to me, but BIG THANKS to HybridZ and all the members that helped out!!!

So I just found the 12v source on the connector that goes to the dropping resistor and jumper the 12v source to all 6 injectors. Tried cranking the motor with the test light connected to one of the injector plugs, but no light. I'm not sure if the way i jumper the pins was correct but I'm running out of ideas. The injectors should of been getting 12 signal with key on, and the ecu should of been supplying the ground. (NewZed) I'm not sure what CSV is but I did just replace my fuel pump with a Walbro running on stock fuel pressure regulator, and according to the fsm 81 uses dropping resistor, but on the 82/83 they removed it, not sure why but on another forum a member claimed that on the 82/83 they made the ecu more "robust" on the ground side.

I've just doubled checked and cleaned all the connectors on the plug and injectors,I tired cranking it again with no luck. I don't have a fuel pressure gauge so I haven't determine if the injectors are getting a sufficient amount of pressure, but I did just realized I was using a 81 wiring harness that requires a dropping resistor for the injectors, running on a 83 ecu that gets direct power from the fusible link. I tried unplugging the fusible link, but then the injector lights don't come on any more. Which then brings me to assume the injectors aren't getting enough power to kick on (THANKS NEWZED). So now i just have to find a way to bypass all the wiring to the dropping resistors to a good 12volt source, any suggestions? I been searching Hybridz to see what people have done when they swap from 81 to 82-83 ecu, but i haven't found an answer yet.

::UPDATE:: So i went to the junk yard yesterday and got myself an ignitor off a na 300zx, and a new turbo coil from autozone. Threw in some starter fluid and cranked the motor, fire up for a split second and dies. I grounded all the wires and mounted the coil just to make sure everything was well grounded, cranked it again but no luck. Bought new ngk plugs and tried starting it again, more disappointment. Threw some starter fluid into the intake and cranked it for the last time, the car runs!!! but the motor quickly dies as it burns through all the starter fluid. Plugged in a 3Volt light i picked up from frys to test my injectors, all injectors connectors blink. Which brings me down to bad injectors, and my questions are there any way to clean the injectors myself, or am i going to have to buy new ones? Thanks again for the help guys.

Thanks for the reply, as of right now i'm getting 12 volt from the from the coil and the bracket is gounded properly. I'm just not sure if i'm getting a pulse from the yellow wire to interupt for the "spark" from the ignitor, my battery died before i had the chance to check. How much were you looking for the coil shipped to 95835? thanks again.

Sorry, I was using my phone in class to reply back to the forum, but thanks for the heads up. I spent half my day at picknpull looking for another ignitor with no luck, but i did come up on 2 pairs of leather seats from a Miata which was awsome for 80 bucks. I was reading in the ignition forum and came across 2 topics that caught my attention, using GM hei or coil and ignitor from a 300zxt. Can anybody tell me which would be the better choice? I'm leaning more towards coil and ignitor from 300zxt but i couldn't find any at my local junk yard. Thanks again for the help.

fixed injector problem fixed, bad grounds. and cygnusx1 mentioned a fuel pump control module that i couldnt find on my harness which i have also seen in the 82 wiring diagram. does anybody know if it applies to the 81 turbo too? so as of right now, everything seems to be good, well according to the eccs scanner anyways minus me not getting spark. 12 volt to the black and white on the coil, and signal when i crank on the yellow and white. does anybody know of anyway to check the ignitor on the coil bracket?

okay' soo I check everything and it turns out to be a bad ecu' picked up an 83 ecu and plugged it right in' right away the light turns on and the fuel pump primes' go for a crank but still no start' I tried starter fluid but still no good' got the scanner in today that i got from ebay and everything lights up except for the injectors air condition control switch' the replacement ecu also came from a donor car that wouldn't spark' soo i'm not sure if its another bad ecu or ignition' starting to lose intrest of the car' seems like everytime I fix a problem' another one comes upp' can anybody help? am I suppose to change the wiring a little since I'm going from a 81 to 83? like the dropping resistor?

yea I been running through the diagram and my wiring a couple times' I followed the 280zx to s30 guide for wiring' but no luck on getting ecu to turn on' I'm also getting power at the ecu from the ignition relay' so right now' my ecu won't turn on nor will my fuel pump prime' or click' I just need a way to Check the ecu b4 I condem that the ecu is broken b4 I replace it' it also looks like the ecu been worked on b4'

i double checked all my wirings. everything seems to be in the right place, but still no luck. my ignition relay clicks when i turn the switch, but nothing from my fuel pump relay. i have power, ground, but no signal from the (red/blue)wire coming from the ecu when i try to prime the car. which leads me to question if the ecu is getting any power. i double check the brown and green wire coming off the fusible link(12v)which was good. i was going to back probe pin 17 to see if i'm getting power off the ecu, but noticed there wasnt even a wire there. so my question is: 1. which pin from the back of the ecu is suppose to be getting power (81 280zx)? 2. how can i test if the ecu is still good 3. i'm missing a wire off the distrubutor to the coil, will this be one of the reason why the ecu isnt getting power? 4. can anybody help?

thanks for the pic! but i couldn't locate the spade anywhere on the dizzy. i tried starting the car today without the wire hook'd up. i didnt get any power to my fuel pump relay nor my ignition. where does everybody else tap in to get their switched power from? and is it possible to move this post to ignitions?

i'm currently trying to wire up a 81 l28et in a s30. does anybody know how this wire and condenser is connected to the distrubutor on a 81 280zx turbo? been searching through this forum and google pics for the pass 2 hours with no luck =( thanks!
