rb20 injectors are 14ohms, gtr injectors are 4 ohms hence 10 ohm is needed

I=V/R

12V / 14 ohm approx 10 ohm resistor + injector (4 ohms)

= 0.857A

P=VI

12V X 0.857A

=10.3 Watts

same as everyone else, 10W and 10 Ohm

Thanks for that mate.

How did you guys go about getting the car to run with these injectors? On the first page it sais the car may not run at all, I have a re tune booked but wanted to install these before the tune but if the car wont run with them then its gonna be kind of hard to get the car to the tuner?

edit : also i have a safc 1 installed already so is there something i can do here to make it run well enough to get it to the tuner? im trying to save a bit of cash by doing some things my self but the next tune is just for the bigger fuel pump, i wanted to get the gtr injectors in and maybe even my z32 AFM as i wont have the money to get these done by the tuner on the day.

You will almost certainly have to trailer the car there, if it runs it will be horribly rich and no doubt foul the plugs and stall multiple times, I wouldn't bother trying to drive it. If you change the AFM as well then forget about it, definitely will not run.

This is prob a stupid question, but why can't you just replace the standard injector resistor on the rb20 with the rb26 one?

You can, but most people sell them for $100, so if you can do it yourself for $10 why not?

Also the standard one doesn't use a resistor as they are normal impedance.

Its just that i saw this ebay auction which lead me to believe that the rb20 did have a resistor. Just out of curiosity what actually is this part?

hey mate ive just acquired some 33gtr injectors to go into my rb20 what resisters did you use? as i want to make one as well.

10W 10ohm from Jaycar, cost like $11 for 6 of them

Have since found a better range of boxes to house them at Altronics

As for getting the car to run I have NIStune and a Tuners license so I can get it running well enough to get to the tuners, will be a couple more weeks till I kick it in the guts though (pipes to be welded).

Its a resistor for something else and not to the injectors as it only has 2 wires

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.

      A bit late but A disk S13P fit over stock R32 GTR brakes, usually A disk front, O disk rear works.

      Or, the height of the release bearing is not correct for your combo. Start with the bleeding and checking the slave moves throughout its range when you press the pedal (2 person required), but it is possible for the height to be internally wrong too (box back off to measure.

      Yes, there's quite a few things that can go wrong during a clutch install. Very unlikely. I have a similar clutch. They (ACS) make good gear. No, it is not normal. It is possible that you just need to bleed the clutch slave. But the new clutch will also have a more aggressive actuation force/pressure, and so your old slave cylinder might be a bit leaky or otherwise compromised, and not up to the extra force required. Or the master cylinder, same.

      Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in?
