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,

L

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.

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.

    • You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.
    • Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?
    • So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
    • It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.
    • As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
