Whats up guys?! I havent posted on here in a while, mostly because the Z has been sitting idly in my parent's driveway while I'm at school and work all day. However I recently broke up with my girlfriend and have found that I have a lot more free time on my hands. lol

On to my question... I took off my stock fuel rail last year because i had just purchased a JSK rail, but never got around to installing it. Since then the car has been sitting outside with the injector holes open to the weather. Is there anything i should do before putting everything back together and firing it up? Should i be worried that condensation got into the combustion chaimber (and caused things to rust) while it has been sitting, or is that not much of a concern considering the small size of the holes?

Also, the stock rail has the inbound and return lines on the same side and both run in front of the block to the solid lines on the passanger's side. Since the JSK rail has the return line coming out on the firewall side would it be a good idea to run that line between the block and the firewall and then back to where the original one was connected?

If any of you have any pictures of your fuel rails installed i wouldn't mind seeing them

 

Also, what pressure is the stock FPR set to? I did not want to reuse it so i got an adjustible one and would like to know what to set it at...

 

Might be a good idea to spray some WD-40 in each of the injector ports before firing it up. OH... before that, vacuum out the ports to yank out any dust / debris.

On my rail, I ran the fuel in around the front of the valve cover, and the out around the back of the valve cover, and mounted an adjustable fpr just above the heater hoses at the firewall. I thought I had a pic online but can't find it right now... I'll post it when I get home tonight. Stock fuel pressure is ~32-35psi.

 

Oh i very much doubt that any debris could have gotten in there while it was sitting with the hood closed and a tarp over the whole thing...

I'll give the wd-40 thing a shot though. Hopefully i can have it running by the end of the weekend.

 

Your projector conversion still kicks @ss dude... welcome back

 

Here are a couple of pics of someone that has the fuel rail, and adjustable fuel regulator. This is how I am setting up mine on my '82.

 

Nice, thanks for the pics Wildman!

Is there any way to know which injector plug goes to which injector? In my infinite wisdom i did not label them when i took them off...

 

Well. There a Batch fire type system. In two pairs of three. One set of Three to the first three injector's. Other three to the Last three. They all have a Green Wire, Find the one with the Brown With White Stripe. That goes to the Last three, Then the other Two travaling with it can go to the other injector's.

Injector Wireing:

#1 W:G
#2 W/Bla:G
#3 W/R:G
#4 W/Blu:G
#5 W/G:G
#6 B/W:G

Just make sure the Brown/White Stripe: and Green Go to Any of the last three injector's. They really Don't matter What Injector, just make sure it's in the right group, for the right set of Injector's.

 

Just to clarify, you're saying that the I just have to make sure that the correct batch of 3 plugs goes to the back three injectors, and the other goes to the front three in jectors, but other than that, it does not matter which plug goes where...?

 

Yes. The right batch go to the right set. Brown goes to the back three.

 

if that doesn't work, send your headlights to me and see what happens.

 

FWIW, on my '78 at least, there are very faint labels on the injector cables, from the factory, labeling which is for which cylinder. I only noticed the printing after I cleaned the whole harness with Naptha when it was out of the car. Don't know if they did that on the ZX's, though?

They are on most ZX's, and some early Z's. But they Rarely make it this long. there were still two on my 81. They just don't last long.

 

If you send me a complete turbo motor i'll consider it

 

if you were closer I'd trade you a partial turbo motor...

 

Has anyone else had a problem with the hose for the Cold Start Injector interfeering with the throttle linkage? With where the hole is on my JSK rail it is pointed right at the linkage rod...

So close to having it all put together!!

 

Have you tried an angled fitting?
