Ah, no it's not.

What you have there is probably from an R30 Skyline (or perhaps 280ZX). R32 GTR resistor packs use a grey semi-oval connector plug and don't have a black rubber boot over the plug. OTOH, R30 Skyline resistor packs look exactly like what is shown in your photos, although the number of wires doesn't look right but that might just be the way the photo is taken.

As far as I'm aware R33 GTR resistor pack is identical to R32 type.

In any event, it will do the same job.

it looks like that thingy in the engine bay of my r32, on the n/s strut tower. my gtr resistor pack u can see the actualy white resistors from the side of it.

The body looks like the R32 GTR type, but the connector is wrong.

BTW, I own an R32 GTR and have a couple of R30 resistor packs on the workbench in my garage.........

Cheers for the info everyone...

I have found some pics of an MR30 pack and two GTR packs...

MR30

This looks alot like it but the plug has too many wires

GTR

Looks totally different...

Another GTR but this one has the same black number code as the one I'm looking at buying...Case slightly different

Does anyone know if the numbers on the pack itself can be used to identify which car it may have come from?

Somethings not right with the one you've been offered if it doesn't have 7 wires. For a 6 cyl car there has to be 7 wires:

1 for battery connection (in the case of an R30 resistor pack that's the red wire on the loom connector)

1 wire for the power supply to each injector, 6 in total (those are the yellow wires, but notice each has a different colour stripe).

There were some 4 cyl Nissans that used L-Jetronic injection and also had a resistor pack, but in that case there will be 5 wires.

Hey guys, this is just a confirmation question. Can you use the MR30 ballast resisitor with the GTR injectors and if so does anyone know what resistance these MR30 resistors are??

Thanks guys

I remember vaguely mine was 5.2 or 5.8 ohms. One of the two. :laugh:

Hey cubes what ECU do you run??? if the high impedance of the RB20 injectors is about 12ohm and the MR30 resistor is about 5.5ohm the final impedance would be still around 7 ohm, according to everones feedback is that the GTR injectors impedance should be around 2.5ohms. Is this suitable to run with a Apexi Power FC????

Any help would be great.

Also has anyone got the part number for the GTR ballast resistor???

The GTR resistor pack measures close to what the MR30 resistor pack does.

Form memory it was actually a little less. Low 5's vs high 5's for the MR30.

All ecu's have a little head room. Ignore the 'theoretical' calculation as its wrong.

Look at what the RX7 blokes run. 6ohm resistors, its what we run and almost every single other manufacture does also. I've never measured a Nissan, Honda or Mazda with a resistor pack greater than ~6ohms.

Theoretically according to calcs they should be running ~10ohm resistors but they dont.

EDIT: I've been running a PFC for 2 years.

      Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

      By R34_GT to Turbo · Posted

      Ok I get you. But isn’t the butterfly intake a headache with the +T?  see this is my plan so far but please advise me into the right direction.  Nistune Ecu, 1000cc Bosch injectors, TD05 or TD06 Kinugawa turbo using stock rb25det exhuast manifold, walbro fuel pump unsure of model I think it’s 450/460, spitfire coils and sparks to suit and a R35 MAF sensor and boost sensor.    I was thinking maybe do a cheap eBay plenum $400-500 or try find a stock det neo intake. I think I’d port match it so it’s getting the full capacity but open to advice please.  Thanks

      R32 GTS (RB20DE) Injectors Replacement

      The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.

      There's a good German place in Brisbane if youre up for the drive 😛

      The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.

      R33 GTR running -9 with no tune

      By joshuaho96 · Posted

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
