Speaking from the Cressida experience, set no.1 piston to top-dead-centre lining up markers on the cam gears making sure it was for the compression cycle, think i needed the cam covers off to check it was, then had to line up a marker on the dizzy to a mark on the block and that basicly got it all lined up. Not sure how nissan engines are set up though, best bet is a workshop manual on how to set timing.

^^ sounds like this may be the drama...

i think lining up the red marker on the harmonic balancer (0 degrees) with the mark on the lower timing belt cover is TDC...

take the cas off while i do this. then line it back up once its at TDC?

Here is SKs article again:

If you are not absolutely confident that you have the timing correct than please take it to a competent workshop if there is one in your city - you don't want to redo all the last few weeks' work.

Yes the fuel lines will hold alot of pressure even when the car is off, there are check valves that do this so there is pressure at the injectors next time you start the car. I'll take a pics of my fuel lines when I get home this arvo, I'm running the stock setup.

It won't be the ignition timing if, all the cam gear and crank pulley marks lined up when you put the timing belt on, and the cas was installed correctly. Even if your cas is in the wrong position, retarded or advanced, the engine will still start. I wouldn't worry about the firing sequence as the NEO's coils and coilpack loom only fit in one way, it would be hard to mix them up.

The fuel injectors don't fire directly into the cylinder, they fire into the intake valve camber, so as long as the injectors fire, the fuel will get into the cylinder. it has nothing really to do with the exhaust cam and valves. An easy way to test the injectors and coils are firing is to remove the CAS, leave it plugged in, switch the ignition to "ON", and spin the CAS by hand, you will easily here the injectors tick and coils fire.

The nistune maps will be stock, but have you tested the ecu works? And are you running the stock AFM and injectors?

Very good point.

At the moment to get it running he has got stock injectors and AFM yes, once its running they are coming out and bigger cc and z32 before its towed to tuner. Dont believe the ECU has been tested to check if it works or not.

If the fuel pump is working, and it does, and the fuel is going nowhere caus it spupts out, would this not indicate a problem with the fuel relief valve.???. Check and make sure none of your boost/vacuum lines are split or pinched off with say a zip tie.

I had a guy with a laptop check mine over last week, cost $80 at home. AFM, A/F ratio, spark, timing, injectors all checked out OK. I still have a prob somewhere but at least I know what is NOT wrong.

The fuel pumps fine...

Ill give this injector and coil test a crack...

So might pay to rip the cam

Cover off and have a look... The 2 cam poimts will b lined up if the cranks on the red (0 degrees) marker yeah?? This will tell me if im a tooth out and if inj and coils are working at same time.

The ecu is my old 1 chipped. Unlikely its the issue but maybe worh ruleingout

yeah, the cam marks will line up once every 2 turn of the crank. i.e 1 cam rotation = 2 crank rotations. don't worry about the markings on the belt, they only line up sometimes.

i also agree that its unlikely the ecu, its just an idea that as you say would be worth ruling out. i only mentioned it as i was thinking along the lines of the base image/map not being saved to the board after nistune was installed. probably very unlikely as anyone installing it would have checked it was all ok before giving it back to you.

removing the cas and spinning it manually will give you a good idea if the ecu is working anyway. if the injectors and coils fire then you know the ecu is getting the CAS signal processing it and telling them to fire.

Replace injectors,afm then tow that peice of shit to turbotune and get mike to figure it out

Ps- is Adam your mate chris?

lol blow me...

seems my fuel lines are round the wrong way :D .... will report back :)

so the car started... had a very big fuel leak at the rear injector,

.... gota take em out and have a play... im guessing just an o-ring drama... :P

y cant the rail be as easy to get to as an rb26 :P

lol blow me...

Was looking at that last night. WTF!!! Looked at the pics and thought "no one could do that, except me"

My fuel lines are actually arse about. Fuel comes in at the back and unloads at the front. This is a mod that was done with FFP.

Hope you are getting sorted.

ok so the cars running....

seems to be pretty good apart from a few things...

how much coolant should it take? i would no have around 9-10L in it i rekn

ive filled it up on level ground, ran it whit bleed nipple (manifold) off, and a funnel with a fair bit in it.

how ever it doesnt seem to want to come out the bleed nipple unless its turned off/turning off....

i can squeeze the thermostat hose and it will shoot up a little bit, but its only once its off that it shoots out as if it should...??

also the turbo wheel sounds to be spinning down once the cars turned off... its a hks 2535 and ive never ran it b4... it only does it once it starts to get a bit of heat into it (no where nere running temp) but still too warm to touch.

Typical of a ball bearing turbo. They spin alot more freely over bush ones

    • My goals for it atm are to get it registered, respray and some mild power gains eventually... I picked up the car from an elderly gentleman near the border of NSW and VIC, its honestly a bit rough and looks like its been driven on a farm (because there was so much dirt underneath). Last week I dropped the subframe and emptied the old fuel out + added a new fuel pump (think the old one went bad from old fuel). Now I'm onto fixing a coolant leak at the rear of the engine + adding a new radiator as the old one is corroded. After that i have a new bumper, coils (as the old were leaking) and lots more
    • Welcome buddy! Plenty on here and YouTube. What are your plans for it? Good luck with the Rwc and Rego bud!
    • Love this so much! Please post a photo when you have a bike on the trailer.  I was a little bit worried about having a tow bar on the Skyline, but having it hidden behind the number plate is genius
    • Came here to say, put all the wiring from the new motor and gearbox in that you can, then throw the stock ECUs in the bin, and get an aftermarket ECU. Should be pretty easy if you can use a multimeter and read a wiring diagram to then use a PNP aftermarket ECU to suit the motors wiring loom, and make the minimal changes you will to get it to work in with the body loom (If any). This will mean you can very easily circumvent/bypass the Park/Neutral start disable switch, and get everything running really easy!
    • If the roof is dual skinned the whole way, IE, there's a "top" metal piece, and a "bottom" metal piece, to slow it down as much as you practically can, you should be able to get an attachment for a spray can/your spray gun, where it is a long, thin flexible hose, and when you're "spraying" it is spraying it in every direction possible. The I'd get that, and feed it through the roof as much and as far as you can. It's basically like fish oiling the car, but you're soaking it in rust converter. Then do the fix like Murray has described having cleaned up the existing metal as much as you humanly can. I'd also throw as much rust converter on that exposed metal before putting the fibreglass/metal filler over everything.   As for welding a replacement in. I've owned my own MIG welder for about 10 years. I've also worked in an industry doing MIG welding for a job for about 3 months dead straight, and we were doing 11.5 hour work days 5 days a week, plus a Saturday 6 hour day. (I then moved over to running the massive CNC plasma as I could understand the technology, and work with the main guy out there). I also f**k around with my welders a bit at home. So what I'm saying here is, I've probably got more hours on a MIG gun than you'll manage to get under your sleeve doing home sorts of jobs over the next 5 years. I also have an ACDC TIG that I got myself a year or two back. I've got a short amount of experience on the TIG only. My home MIG is also presently setup for doing thin sheet metal. Unless I didn't care about how that roof looked, and I just wanted a functional metal roof, and it being out of alignment, warped, and bowed, I would NOT attempt a roof replacement UNLESS I could do it as a whole panel like Murray described where the spot welds were.  Welding has this REALLY annoying thing, where if you want something to be perfectly square, unless you can clamp that thing to damn perfection (Welding fixture table), it is NOT going to be square, so you start to learn, the type of metal you're working with, how thick it is etc, and weld in VERY specific ways, and by knowing how YOU are as a welder, so that as the welds cool, the metal work pulls itself into place. If you want to see some cool tricky shit done, Bennets Customs is an Aussie guy, and he mentions a guy a lot call "Kyle", who is from "Make It Kustom". Watch some of their welding videos, especially on sheet metal. You can use the welder to shrink the steel in, and you can also use the welder to stretch the panel out. When you have the skill level that I have, you can shrink the metal in and out... But never on purpose like those two guys do. You just manage to f**k it all up. Then I smack it around with a hammer till it sits lower than I will want it too, then I shove filler on top and then pray to deitys that I can sand it into some form of sane shape that doesn't look like a dog has taken a shit, after eating a tonne of pumice stone... I'm all for DIY, and for learning, and please, feel free to give it a go, but be aware, you need to live with the consequences of how time consuming it is to do, AND that it's going to look no where near as good as what you can make it look with just some filler now. Oh AND, even once you replace it, it's like to still rust away again eventually, because you'll have missed putting primer and paint on some part of the newly welded in sheet metal, or against part of the existing metal you couldn't get to...   Oh, and to weld all that in, you will need to pull the window out, and strip at least the roof and A Pillars of interior trim and wiring. You'll then need things like the big fire proof/weld spatter proof mats to lay down, OR you'll end up needing to strip the ENTIRE interior to avoid sending it all up in a ball of flames. If you want to see how annoying sheet metal is to weld, head to bunnings, buy there 600x600 1.6mm mild steel (Not GAL!) sheet, and cut a few pieces, and try and weld them together. Then understand, 1.6mm sheet is nearly 50 to 100% THICKER than the cars sheet metal.   The photos I posted before, I'm replacing with 1.2mm thick mild sheet, and it's very easy to blow through both the original steel (Especially if I hit an area that should have probably been cut out a bit more) or straight through the new sheet metal. And I'm doing the floor, which can be hidden easily, and doesn't matter how pretty I make it, as long as it's damn strong! I'm also doing it in a 4WD, that has seen many off road trails, and doesn't need to look that pretty ever
