Hey guys...

Im in a little bit of a dilemna. i need to know how to tell for sure that my engine is a series one motor.

I have a 94 model r33 gtst, and ordered myself some splitfire coilpacks a couple of months ago.

anyhow, upon receiving them, and for the first time looking for my igniter pack... i realised i dont have one....

This would usually be a sure sign its a series 2 right? I never thought 94 models come with series 2 motors but?

The coilpacks look exactly the same as the ones in there now so i dont really understand why the wouldnt work?

Thanks for your time guys,

EDIT: Pictures added below

Cheers.

it could just be that the coils had been changed to series 2 coils.

the easiest way to tell the difference in the motors is the TPS. if it is rectangular and only has 1 plug then it is a series 1. if it has a rounder TPS and has 2 plug (only 1 may be hooked up) then it is a series 2.

The series 1.5 also uses blue stickered 3 pin afm...

Series 2 coil packs have the ignitor on them which you can tell by the addition of a step on the series 2 coils that has IB G +1 on them like in this picture i took

The Series 1 coils do not have this step as the ignitor is on the engines valley cover.

If your car is a 94 model then you should require Series 1 coils with model number SF-DIS-001

As Series 2 coils were only put on cars after January 1995 on the late model series 1.5 model number SF-DIS-005

Series 1.5

The coils you have in the engine at the moment appear to be series 2 coils that have the ignitor on board the coilpack.

Pretty rare that they are in a skyline so early.

This is more than likely why you were sent series 1 coils.

Do the current coils have a carbon rod inside instead of the little copper coil like the splitfires do? As these were the transition between the 2.

The splitfires you have are series 1 coils and will not work.

You can see in picture 2 that the coil has the added step.

You will require SF-DIS-005

You mean where the coil contacts onto the plug??? if so, then mine has the similar coil contact to the splitfire plug, the copper looking one.

Big thanks for your help mate.

The condition of them cant really be seen.

The only indication really is mechanical like small misfires etc or on the coilpacks themselves there will be a whitish burning on the sides.

This usually comes well and truely after they are stuffed and your having huge misfire problems and changing plugs every 500 kays wondering whats going on :(

If you still have the black plug cover on that says "nissan twin cam" etc remove that and the coils and spark plugs will be under that. You will have to undo the intake pipe and twist it up so you can get the plug cover off. I have done it with out adjusting the intake pipe and it was a nightmare.

      S1 rb25/s14 starting problem

      When you crank your car, and hit it with a timing light, can you see a steady crank timing?

      Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov

      yeah I was shocked when I checked my spare OEM on and as below that's how they come from Nissan. (side interesting note new NEO gearbox and replacement park lack the brass bush on the tips and its just all alloy) unsure about damage to the box currently back at 1110 to be pulled down/inspected and selector fork replaced as he built it previously and given the never before seen failure on his billet forks he is replacing it under warranty. He said he has used always OEM the keyway tab without issue for years so it could be an unlucky coincidence. I did talk to him about the sharp corners and stress concentration too. Re: hard shifts i got 7+ years out of the OEM one and the fork itself failed not the keyway. so could be bad luck as I said or an age thing + heat cycles in box and during fabrication of billet?
