Jjr Coils Won't Work With Stock Wiring Loom

Hi Guys,

I have been having problems with my stock coils for ages so I finally bouught some JJR coils from justjap for a series 1 R33 GTS-T

Pulled this old coils out this arvo after some dramas with stripped screws and other such un-fun doings, put the new coils in the brackets and went to put them back in only to find my wiring loom won't connect up. Comparing a new coil to an older one, the design seems ever so SLIGHTLY different. Different enough though to have halted my progress and frustrate me to no end.

I am wondering if

A: The coils actually require a new, matching loom (Justjap website said direct replacement though)

or

B: They accidently sent me Series 2 coils.

I don't know how different S2 coils are to S1 coils.

Any suggestions? Its too late to call them now and ask and I was kinda needing the car tomorrow for work. I really do NOT want to have gone to all this trouble just to have to put the old coils back in :)

Like Splitfires they hook straight up to the factory loom.

Did you order the right set? It is possible pending the actual month of manufacture of your car that it is a Series 1.5 and therefore you will actually need Series II coils.

Did you check the compatibility on their website before you bought them to ensure you got the correct set?

Hey, thanks for the quick reply. My car is a 1995 and is listed as a series 1 so I just bought series 1 coils. My car may be a series 1.5, I was unaware they had Series 2 coils?

I just looked at them further, the earth and positive are reversed so they are definetly the wrong coils for my car. The receipt from justjap says series 1.

If my car indeed does require S2 coils, being a late 1995 series 1 (and thus possibly a 1.5) then the mistake is mine for assuming I needed series 1 coils.

What does the TPS look like?

If it is square with two plugs coming off the same side then it's S2, if it's rectangular with one plug coming off the side and wires going to another plug then it's series one.

Series one coil packs have 4 little bolts holding them to the bracket, Series 2 only have 3

"Series one coil packs have 4 little bolts holding them to the bracket, Series 2 only have 3"

Gah.

My old coils have 3 bolts, the new ones have 4.

Sigh.

My car IS a series 1 though. What did nissan do, just throw random S2 bits onto the 95's for the hell of it?

Gonna have to call Justjap tomorrow i guess and try get the S2's sent out. Screw putting the car back together, Ill just have to take the bike tomorrow.

Thanks for your help guys. I feared they had sent me Series 2 coils by mistake, in the end it turns out I NEEDED series 2. Bloody Nissan.

I have a set of S2 JJR coilpacks here if JJ won't take them back. These were in the car for 2 weeks. I can sell the other set as series 1 which is what I intended to do with this other set if that helps.

95model R33's have a S2 motor... I know because I have one

Yes. I was unaware the 1.5's used the 2's engine. Lesson learned I guess.

You click on the S2 coils on the Justjap website and it says

"Engine Compatibility:

- Nissan R33 RB25DET (1/95-5/98)

Which I would have seen, except that I didn't even bother clicking on the S2 coils as I dismissed them thinking I needed S1 :)

1995 are commonly refered to as series 1.5, have some parts of the series 2 and some parts of the series one

yeh yours will probably be series 2 engine. Two easiest ways to tell would be looking at your TPS as already mentioned or looking at the back of your engine valley cover and if theres no igniter there then u will need series 2 coils.

ah im tired so if i've stuffed up someone correct me haha

Easy tiger, read the post properly before you jump the gun.

I am certain that if the wrong coils were ordered they will be more than happy to switch them over :)

hey blitz, im referring to 3lit3 32's comment, not lachlans :O

      gtr hood match gt/gtt front fenders?

      After @Kinkstaah debacle, I'd never want to try and get it right 😛

      The hood lines up with the fenders. The front bar doesn't perfectly line up with the fenders where the wheel arch is. You have to 'squeeze' the front bar 'in' as it wants to naturally flare out and be longer on the sides. There's a few threads where people notice this when they only swap a GTR style bumper and front bar. Unless you have genuine OEM items - you may be better served getting conversion kits. There are GTT bumpers to fit GTR hoods. There are GTR hoods (non genuine) to fit the GTT bracketry. MAY

      Mistakes were made, my R34 Story

      The real question is, on some of those wild roads they call highways, how many times did a farmer in an old ute from the early 2000s blaze past you over double lines?   Tassie is a wild and really cool place, and after doing a work related road trip there January of 24, I understand why Targa Tasmania is ran there, and is so tough to do well at! We had a brand new Camry Hybrid that handled quite nicely, and thankfully weren't in an old car, because cresting some of those hills in a 100kmh zone for it to suddenly be like "surprise f**kers, this is a recommended 30kmh hard right turn" wouldn't be pretty. We weren't racing the Camry around, but we weren't slouching in the bends either. But my lord those old farmers know their old clapped out utes, and those roads, as they were absolutely hammering it!   You're also super lucky to make it up to Mt Wellingtong this time of year. It's often road closed with snow/ice! Also, I hope you hit up Salamander Road in Hobart for some insanely good food (I highly recommend the dimly lit Irish pub for a Guiness Pie, or even the bangers and mash!!!)   How long did the Ferry take to get across? I want to do a road trip of Tas on my own time, but I get horrifically sea sick, and I don't want me on the Ferry, just the car 😛
