hey guys,

recently bought a rebuilt HKS 2530 turbo to go on my RB20

im just wondering what injectors i should use,

ive seen people using GTR injectors but id like to get some brand newies instead

ive been told sards need to wired in and i cbf'd with that soooo any recommendations?

also will be installed with a pfc tune if that makes any difference..

cheers in advance for any help

and yes ive searched all i can find is people using 2530's on their GTR's

Just use the some GTR injectors slacker, get them cleaned & flow tested first. They drop straight in, only extra bit of work you need to do is the resistor pack but even a 10yr old girl could do that

They will flow plenty, more than enough for the power your 20 will put out so no point going bigger

Do the correction on the PFC & your set to go for a tune

if you dont want gtr injectors go with nismo 555cc, collars should fit straight up and you'll have no problems. also i'm assuming u have upgraded your fuel pump for the demands of the turbo? cheers h

CA18DET injectors, i believe they are 380cc you can get them almost free, they fit straight in and they do not need resistor pack (correct me if im wrong), just get them flow tested to make sure they are working fine. Will need full tune however and new o-rings are recomended, source from nissan

Off the top of my head I believe CA18 injectors are 340cc & are still low impedance injectors (same as RB26 injectors) which means resistor pack is still required if running them on an RB20 as RB20 uses high impedance

As far as I know, S13 CA18DET run a resistor pack standard similar to the GTR, that's why GTR injectors are a quick easy upgrade for CA18's

Correct me if I'm wrong :)

Corrected...ca18det injectors are 370cc...

cheers guys

ive been reading rekins thread of him installing gtr injectors and he seems to be having trouble with them fitting straight in (he needed to trim some of the plastic off) why would this be?

do r33 gtr injectors drop straight in or just r32 gtr?

Yes all rb GTR injectors will drop in (you will still need ballast resistor), the R34 ones are natural metal colour, not painted black like R32 &R33 GTR ones, my advice try and find newest or best condition ones you can, one of my GTR injectors first time round started to leak even after getting cleaned and tested, ended up having to buy another 6 because no one would sell me a single or pair, all 6 were cleaned & tested again with new rings, pintels & baskets.

Nothing you can do to repair a leaky injector and a leak wont necessarily show up during the cleaning process, if i had to pay for labour twice it would have been cheaper to buy brand new nismo ones off the shelf.(not to mention cost of lost fuel driving the car around for 2 months before i could get a day off to get it fixed)

Don't waste your time with the red rx7 ones or sard injectors, they have crap spray patterns that don't atomise the fuel properly, leading to crappier fuel economy over nismo ones, but i am sure others would argue that point.

TOTALLY AGREE.

Been having ongoing issues with my GTR injectors cause they were old. I had them all cleaned and tested, and have had issues with 2 of them so far.

Lucky for me, I have been able to find individual ones, but it has been a pain in the ass troubleshooting and fixing them. I think I have taken the injectors in and out about 6 times now.....at least I have gotten good at it now ;)

    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option 
    • You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
