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.

ok, now you sorted that out, I have a question. where are the coilpacks? how do i take em out? I'd like to have a look at the condition of them. sorry to hijcack and be a n00b..

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.

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
