Hi All,

This is for all 260RS owners out there.

I understand that R33 Gtr have low impedence injectors and have a resistor pack mounted on the strut Tower.

260Rs have same running gear but engine bay has some subtle differences. Eg. Battery

In particular I'd like to know where is the damn resistor pack in the stagea?

I've looked everywhere. If people could put up a picture of their engine bay of they're still running low impedance injectors.

On a GTR it is on the drivers side, in front of the strut tower. Small silver box with 8 wires coming in. Can you take a pic of your bay?

Yes thats where ive been looking and no silver box. On the R32 GTRs its mounted on the same bracket as the boost solenoid. On the R33 GTRs its as you mentioned above. On the 260RS No sign of it ever been there.

The boost solenoid is actually wedged between the battery and the fuse/relay box on the 260rs. You can barely see it. Ive seen some pictures of stock 260rs's on the net and none show the resistor pack on the strut tower.

I have heard that the resistor pack can be wired anywhere between the ECU and the injectors, is that right??

Anyway this is my engine bay.

I think that big grey plug is the injector loom, can you follow it back?

Yes, the resistor can be anywhere. You can check inside near the ecu perhaps, also the fuse box is much larger on the 260, it's not under or inside it is it?

No-one has changed the injectors already? I can't really see them from the photo. You could try measuring their resistance...

Good point about being under/around the fuse box.

Would have thought it would be as close as it can be to the injector loom. can you not follow everything that hangs off that ?

No blank plug with wiring turned back into itself?

In my 32GTR they have just put a plug in it.

(I use it as an anti theft device. Pull the plug out and put it in my pocket. Turns over but will never ever start :thumbsup:)

I thought of that since there was so much space underneath the fuse box but nothing unfortunately, only the boost solenoid.

I thought someone may have changed the injectors but they are the standard low impedance GTR ones (checked them with a multi-meter).

No blank plugs or anything, I've followed all the cables from the injectors back and they seem to tie in to the loom that runs along the firewall and then through it to the ECU.

BUT..... After 3 days of seriously non stop searching google and SAU i finally found this

http://www.skylinesaustralia.com/forums/topic/402139-rb26-injector-ballast-where-do-i-plug-it-in-on-rb26-loom/

and sure enough its located behind the passenger headlight under the airbox /pods up against the fender wall. As per the pictures. Seriously i have no idea why its so far away and also how they wired it up. It may actually be that massive grey plug sticking up away from near the FPR.

I wonder what else is differently located. While we are on the topic of 260RS differences, one thing ive never found an answer to is whether the ECU pinout for R33 GTR and Stagea 260RS are identical.

I have the Japanese Stagea manual for all series 1 Stags and the R33 Engine Manual for all R33 engines but I cant find anywhere a manual for the 260RS and it seems there is a consensus that the ecu may be a hybrid R33/34.

Can anyone help on this?

      Block bump. $400. As above cyl 6 needs bore or sleeve.

      I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.

      Ethanol Content Sensor - Always at 11%?

      I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.

      From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.

      They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
