Dont go buying a pump if you dont know if its a clog.

Didnt MSA sell these years back (4 or so)? I dont remember if they were nissan parts or reproductions. They were still really expensive, good luck.

Bump! Quick question, it says the 78 alternator is 60amp, ZX alternator is 70amps but is it (78's) internally regulated? It appears the 78 and on alternators all work for this swap? Is there any benefit to keep the 81 turbo alternator on my turbo motor on my 78 Z or should I just swap it out for the one originally on my 78? Thanks

Well I worked on it last night. Used old wires from my parts ZX, found some that were the same gauge as the original injector wires and then bought a 12 pin connector at radio shack. Everything will be soldered and then sealed with a section of shrink wrap. Im still needing to decide how Ill wrap the whole thing to make it look nice and be sealed. Now its just waiting on the rest of my injector connectors.

Picture I found just now of something similar to what Ill do for the oil lines. From this thread. http://forums.hybridz.org/index.php/topic/94089-id-oil-filter-assembly/page__pid__886739#entry886739

Bump. I have parts for trade. Need this soon! Thanks

Ive got one in my 81 turbo. Let me know a shipped price thats worth it to you and Ill pull it for you. Thanks

Had a wedding reception at our house this morning (wedding was at 630am!!) so I didnt get to work on the car till like 3pm. haha But I was able to set up the fuel lines, filter and fpr. I cut off the normal bracket attached to the FPR so it is nice and smooth and I bent the bottom line strait down for a cleaner look on the rubber lines. Also started looking at the wiring for my fuel injectors. I didnt want to have any wires going over the top of the manifold so I decided to make a wiring harness that would run right under the fuel rail and via a plug connect to the wires ran on the back of the firewall. I went to radio shack and got a 12 pin connector and ordered another set of new fuel injectors connectors. Luckily I had 2 left over from my turbo wiring harness so I used those to cut everything to length to where all Ill need to do once I get the new set of connectors is solder them on. Started to look at the oil cooler lines as well. I cut the press fit rubber lines off of the lines that connect to the engine and am planning on the tips getting flared with a new fitting. I can then buy a set of hose with flared fittings on each side to connect to the oil cooler itself and the fittings on the oil sandwich plate. Hopefully this week Ill get my injector connectors and Ill finish up the injector wiring. I may get my db37 megasquirt cable so I can begin to dissassemble the stock ECU connector and begin to trace the wires into the engine bay using twoeightythreez's write up. http://forums.hybridz.org/index.php?showtopic=48292 I still need to get a hold of the following parts... 82-83 turbo dizzy CHTS TPS IATS Not neccesary but a downpipe, since Id like to plan the wiring for the wideband. Ive been watching the listing of cars at our local pick and pull. Hopefully I can find the cars I need. Heres a few pics. And no I didnt hack out a 3 ft section of the dash harness on my ZX to get some free wire....

Downpipe and exhaust is good for your money. What do you mean what mods will carry over?

So I liked the idea of just having the single plug on my injector harness for when Im working on the engine. I'm starting to work on some of my engine wiring for megasquirt and I was curious if using say a 12 wire connector off of my parts zx would work. Would this interfere any significant amount as far as voltage drop or anything? Thanks for the help!

Yeah, blow compressed air throught the lines to the tank.

Just wanted to make sure the front (closest to front of car) is the feed line correct? I want to make sure before I run all the lines, haha. Car is a 78 280z but it's the same for all the s30s I believe.

Do you have ac? No easy way to modify the manifold. Now if you made a custom manifold you could cut off the pcv tube on the block and move the collector to the front half. But really all that's really not worth it.

Good luck getting the MSA downpipe or Scotty's downpipe (same thing, MSA was selling his a long time ago) to fit on a ZX. The firewall is way to close to the back of the turbo on a ZX and you cant hardly do anything but a quick 90 coming out of the turbo. Best bet is to make your own in cheap metal and have a shop make it in SS, assuming you can weld some exhaust tubing together. You also might consider removing the stock wastegate, thatll give you an inch or so more room to make a smoother bend downward but youll still have sharp bends since even as you get the downpipe pointed towards the transmission tunnel the sides of the transmission gets in the way. ZX are a ***** when it comes to a downpipe, another reason to buy an s30! haha

Well glad to know now. Haha. I bought the things like 5 years ago and they were sitting in my closet so I was happy to find them. I really had two problems. The bolts would go in a quarter inch or so and then it was really hard I actually broke one bolt off putting it in. I lifted the engine enough to pull them out and then just ran the bolts in till they worked. I'm not sure what the problem with the threads were but I let the bolts "clearance" them till they fit. Haha Once that was solved I found the holes wouldn't line up. I could almost get the metal engines mounts close to the rubber mounts holes but that was without the metal "c" shaped spacer.

You talking about the vacume control or the cold start injector?

Thanks! Edan Ill be using the stock 4 speed that was in the car for now. I have a ZX 5 speed from a NA car that Ill be installing down the road. Ill have to replace the clutch then as well. Two80z4me Ill actually be replacing most of the clips and plugs. There is no way Ill be doing all this work and keep the original wiring clips. haha

Well I pulled the engine out of my 81 turbo and cleaned up the engine bay on my 78. Cleaned up the engine and replaced misc gaskets and scrubbed the whole thing down for about a week.. haha Well It finally found its way into my 78. The plan is pretty strait forward, MS2, FMIC, BOV, ~13-14 psi. Ill be using an 82-83 dizzy for direct control from MS. It took me nearly 5 hours to get the 4 motor mount bolts in. Im thinking it was the motor mounts I bought from MSA, they might not have been made correctly? The bolts wouldnt even thread in all the way and I had a huge problem getting the bolts to go in once I chased the threads on the mounts. Anyways after a bunch of fiddling and messing around I was able to get it in. My dad. Me. Im start school again on september 1st and all my money has gone to that so Ill try to find stuff to do that doesnt cost anything. I have my megasquirt wiring/plug coming so hopefully Ill be able to wire that up and get some of the wiring routed in the engine bay.

I guess I'm not geeky enough. What is it?

Yeah if you dont have a set of electronics yet youll have to decide which one youll buy. Are you putting it into a Z or ZX?

Auto or manual? Did it come with a clutch or torque convertor. Basically it comes down to what electronics your using the engines themselves are basically identical but the turbo 81, and turbo 82-83 had different distributors.

Alot of people do as killerbjt said. Square port on a round port head. Read up on NA L28s in the 6 Cylinder forum. You may decide to just combine your first and second step down the road. From what Ive seen on here and other websites, your stage one deal on a stock engine and computer will probably do very little, you might even sacrifice power at certain RPMs.

Were the front three better or worse than the back three.
