especially grounds or on your side of the planet - "earths"! 1200rallys probably right - check voltage - black lead on test meter goes to - batt. terminal, + goes to big white?? wire on back of alternator - thats where you'll get your reading of under or over 15V.

I thought you aussies were all rugged car survialists, whats this wimpin out & not adjusting your valves

read the tuning spec's for setup with AC - should require a higher idle then non AC or just try increasing the idle speed while running the car w/AC on & see where that leaves you when you turn the AC off.

Pinging is the timing or in need of a higher octane fuel.

well see, your smarter then me cuz I forgot to have the exhaust guy put one in when I had him cut & re-route the pipe. I planned on it, just didn't remember it. I may run it through emissions just to see where it at currently.

Bummer about the header, I hate wasting money like that but sometimes it can't be helped - you just dont know until you try something.

Can't you just split the MSD box & send the signal to both sides of the head? Wouldn't it have enough juice for that? I'd think you'd be able to double wire it directly from the box to each coil, matter of fact you could temp wire double ends to it & check it with a meter to see if it was equal output.

cant remember where I bought it exactly, online somewhere but here's the model & brand. Its the one with dimming, compass, temp & map lights...

just look on line, it was about $150 US

have the muffler shop guy put a bung into the head pipe for the ox sensor if you hadn't thought of that already. I planned on ding that and running the same A/F gauge for jetting purposes.

missed your post about ultrasonic cleaning, hadn't thought of that. Is that primarily what you're using? I dont know of anybody around here with a parts dip hot tank - too much EPA BS for people to deal with.

thanks guys. Now if I can only get the jetting set properly, its close but it seems like I should be able to get it better, trial & error it seems.

here's that PCV valve setup:

Cannon single side draft intake w/a Weber DCOE 40 - this manifold happened to have a port plugged off with a 1/8" fpt (fine pipe thread) plug & I got lucky at the oddball hardware store (Hardwicks on Roosevelt for the local boys)great store, have all kinds of unusual fasteners, fittings, etc...i always go there when I have a hard time finding anything.

Found a nylon 1/8" FPT x 3/8" hose fitting & screwed it in, attached the PCV which I scrounged at the local O'Reilly's, got a piece of 5/8" fuel vent line & plugged the two together. Had to run the 5/8" hose under hot water first before I could get the PCV valve to fit but it worked.

Seems to work fine.....





Since I'm looking at it I'll explain the accelerator cable - it is a hybrid - I made this out of a toyota cruise control cable I found at the pull a part. I first went looking for a cable with a round ball on the end to fit the Datsun acc. pedal , pretty hard to find.Found the Toyota cable w/a round ball so I took the original Datsun cable apart & kept the screw on bezel that attached to the firewall & epoxied the toyota cable sheath into it. The Toyota cable had that nifty end that worked well with the bracket I fabbed up so then I was able to slip the cable into the new cable housing & secure it to the bracket I'd made. More oddball engineering to make things work.

here it is on the bench, you can see the epoxy goober on the threaded fitting end if you look close...

I thought 3 balls in a set was normal, something wrong with that

Your right, the orange is on top of the doors, I painted it that way & re-made the door panels w/o the metal cap/top piece of the original door panels. I guess thats the style of the sedans & the utes I think. I just thought it'd be nice to have a touch of color in the car as well.

Thanks Ernie! I want to see your ride, maybe at the Nissan meet at Shilshole in feb?

I dont think I ever mentioned the spec's on the drive train so for those that want to know:

nice job, looks similar to my project. Its a nice feeling to have gotten it that far isn't it....

Keep it up!
