S1 And S2 R33 Gtst Coilpacks Is There Any Difference?

[Jay_stylz]

is there any difference between the s1 and s2 coilpacks?

[Benzino33]

i just answered your question in your other thread about std 33 coils. besides there have been many threads on this topic before. just use the search function..its your friend

[Dorifta]

infromation is there in the search functions, read it all, its stupidlly conflicting, several people say s2 has built in igniter and several people say s1 has built in igniter, no definitive answer, without looking from memory s2 has built in igniter, I think the r34 has built in aswell,

can anyone confirm diff between 33 s1 and s2 and r34, can u see the built in igniter,

what? clearly series 1's and 1.5's have one main ignition module. this goes for all earlier models on skyline e.g r32 rb26's.

from series 2, the igniters were built in. i dont think theres any series 1's with built in igniters.Im pretty sure there are none,unless theyre modified in some way?

actually series 1.5 generally have the s2 engines so will have the ignitor built into the coils. at least that is my experience with the s1.5 i had and all the other ones i have seen.

but it is extremely easy to tell whether the car has an external ignitor or not. look for a square unit at the back of the engine bay on the rocker cover with a plug on each side. if it has it then it takes s1 coils. if it has a plug but no box it takes s2 coils.

Yes my 1.5 (1995) has the series 2 running gear. To my knowledge all of them do, and I'm guessing only the earliest of them...if any...will have series 1 running gear.

As mad said, check towards the back of the spark plug cover...if there's a black box on there then you have series 1, if there's no black box there then you have series 2. Simple. Search the forum for pictures of said ignitor.

As far as I know all 01/1995 and later R33's had S2 engines

strange cause my missus has series 2 coils on her 94 line but i have series 1 coils on my 94.

hers has the mounting point for the main igniter but instead its just the plugs joined with no igniter. know what i mean? lol.

so is there any way of just plug and play with the diff coils?

there are possible reasons for a 94 model having s2 coils. it may have had an engine transplant, it may be a very late model 94 and just got the s2 engine, etc.

you may possibly be able to install s2 coils onto a s1 if you swap the whole ignition loom. not sure if the plugs at the back (where the ignitor usually is) are the same though

hmmm thanks marc

[Jay_stylz]

everyone says to search pics of series 1 and 2 coilpacks lol but i cant find none i need to know which one my car has in it lol all i know the car has ecr r33 on the compliance plate what does that mean? lol i dont say what month it was made in either lol any ideas/help?

[SLY-25T]

not the best of pics but the coilpack cover (where it says 2500 NISSAN on top of motor) has a lil box on the back. in the pic its just above the BOV. If you zoom in its got a plug either side.

That one is the series 1 coilpack with an external ignitor.

Series 2 doesnt have this box as each coil has a built in ignitor.

ok deff no little black box there hmm soo what does this mean? series 2 motor?

[SLY-25T]

looks like it mate

[mad082]

you can also tell if it's a s2 motor by the shape of TPS unit and the colour of the sticker on the AFM as well if i remember correctly

[PIOTREK]

yer the coil pack are different 100 %! i changed mine yesterday

Look at the top of the motor and see if you got that little black box there. can i ask why are you changing them- miss fire?

make sure that you are sure its a coil pack before u spend too much cash on the wrong thing

let me know if you need a hand with it, cause i just went through it all and i'm not sure if it might be the leads too, but it has stopped missing.

There are quick diy fixes to the coils, refer to the sticky. Probably do that first, to make sure that its the actual coil

[Benzino33]

the colour of the sticker on the AFM

Are S2 AFM's pink label? Coz i got a 93 S1 and i got a pink label afm. does that make a difference to the readings, performance etc.?

[mad082]

don't think they read any different, but i have a feeling that one has 3 wires and 1 has 4, but i could be wrong there. it's been a few years since i read it.
