Yellow Jackets S1 Vs. S2 Rb25det R33

[Lost]

Hey,

I have managed to locate some yellow jackets which are being sold second hand. Problem is the seller does not know whether they are S1 or S2? Does anyone know what to look for to tell the difference?

I noticed that my original coils have a tab on each side midway on the plug. The Yellows have one higher up. Does this help?

Cheers and thanks so much in advance,

Assuming these are pics of the actual coil packs. It looks like the S1 has the black mounting bracket all the way around. and the S2 does not.

Yep, series 2 have built in igniters so they only have the mounting bracket on the ends, not all the way around.

Thanks guys. Does anyone know if original R33GTST S2 coils also have 2 mounting brackets or do they have 4? I'm now confused as to which one mine is as I thought is was S1 but could be S2. Made in 04/95 with Type M kit.

is there any major advs of the s2 compared to the s1?

or are they just design differences for the r33 s1 and s2?

S2 has built in ignitor, S1 doesnt. they are model specific. there's no performance difference.

You can tell if you have series 1 or series 2 by looking at the back of the rocker cover. If you have a black box on top of the cover with wires coming out of it, you have a series 1. If you don't have this black box, you have a series 2. Chances are if you car is 1995 it will be a series 1.5 which uses series 2 engine and therefore coilpacks.
