The coil pack's are differnt.

On the series 1 their is a little box at the back of the motor and on series 2 their isnt any little black box.

The CAS looks a little different to the series 2. - only minor features.

The colour of the engine rocker covers. Series 1 are darker cover and series 2 are shinier silvery colour.

Look at the Nissan Japan Co manufactory plate or compliance plates :wave::wave:

You can look for the ABS system in the right hand conor of engine bay. - Series 2

The rear wing and body kit is different, steering wheel is different, seats are different 1995 - 1996 mdls.

Air bag on series 2's

I carnt think of anything else.

Not quite right. Many series 2's don't have ABS. Mine included. I'm sure there is a thread on differences in the FAQ section.

It's just an engine, it has been painted, and it dosn't have the intake pipe to the throttle body.. :D

But it has an ignitor pack (little box as cameron called it.) so it is a series 1 which I worked out after making the first post about 10seconds later..

Just dropping it into a GXI for someone.. only wires that look different are the under dash ones it has a multi junction where the earlier nissans have a smaller plug. Anywhere on the net to get the diagram from the RB25T looms, not just engine loom?

I have done a search, looked through the FAQ section and havent been able to find any information that says that S1 parts can be used on s2's and vice versa.

What I want to know is.

1. Can a S1 coil loom and engine loom be used with s2 coils.

I'm using new splitfire coils for a S2 and the s1 plugs dont fit.

2. The coil cover has an ignitor on the top, at the back. This is a series 1 part?.

Looking on the underside I noticed it has 10/94.

3. Are there different versions of PFC's for each series?

On the side it has these numbers. PFC RB25 9910-0035

4. Is there any markings on the head to identify what series it is?

The guy I bought the engine off said it was a S2, but after finding the coil plugs not fitting onto the S2 coils I need to know exactly what I have.:slap:

I thought I'd better sort this grey area out before i buy any more wrong series parts.

      R34 Skyline climate control unit transistor

      I know why it happened and I’m embarrassed to say but I was testing the polarity of one of the led bulb to see which side was positive with a 12v battery and that’s when it decided to fry hoping I didn’t damage anything else

      R34 Skyline climate control unit transistor

      I came here to note that is a zener diode too base on the info there. Based on that, I'd also be suspicious that replacing it, and it's likely to do the same. A lot of use cases will see it used as either voltage protection, or to create a cheap but relatively stable fixed voltage supply. That would mean it has seen more voltage than it should, and has gone into voltage melt down. If there is something else in the circuit dumping out higher than it should voltages, that needs to be found too. It's quite likely they're trying to use the Zener to limit the voltage that is hitting through to the transistor beside it, so what ever goes to the zener is likely a signal, and they're using the transistor in that circuit to amplify it. Especially as it seems they've also got a capacitor across the zener. Looks like there is meant to be something "noisy" to that zener, and what ever it was, had a melt down. Looking at that picture, it also looks like there's some solder joints that really need redoing, and it might be worth having the whole board properly inspected.  Unfortunately, without being able to stick a multimeter on it, and start tracing it all out, I'm pretty much at a loss now to help. I don't even believe I have a climate control board from an R33 around here to pull apart and see if any of the circuit appears similar to give some ideas.

      Nah - but you won't find anything on dismantling the seats in any such thing anyway.

      Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
