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 ;)

    • Hey keep the ideas coming, I'm always keen on projects! But, problem fixed!  I got a cheapie ozito scope from Bunnings and had a good look in and around the bearing and sensor hole. I couldn't see a smoking gun but the bearing looked a bit strange, especially when comparing with a new one. I thought the cover had come off the bearing magnets.  Sorry for pics of a screen, I didn't have an SD card.     Good thing I had the old one to inspect. So, given I'm like a pit crew with wheel bearings and luckily I had a spare bearing because I f**ked up my parts order, I decided to just smash it out. Got the old one out in about an hour. So much easier when the parts haven't had a chance to rust together yet. 😂 And, well, found the problem.    In the second pic at about the 8 o'clock position, you'll see what I think is the tip of the old sensor.  The new sensor has definitely been rubbing but it's all intact, just a little shiny so I'm hoping it's fine.  The car brakes perfectly now and no errors.  I think the job took about 2.5h in the end. 👍🏻 I really appreciate the help in here as usual. Thanks guys.
    • I was only looking because I saw some drops on the ground but it wasn't alot. Recently had it serviced will ask the mech to confirm. Find it strange that it looks standard though, can see in another photo of a random box 
    • So...not sure if you know if that has always been there or why you went looking. It could be old damage from a clutch explosion, or even just the gearbox got dropped somewhere along the line. Basically, you should seal it up to stop oil and dust getting into the bellhousing, but it doesn't matter too much and is not structural. I'd suggest something like a glob of JB Weld. BTW what gearbox oil are you running, I would guess the breather has been spewing it everywhere.
    • Hey Duncan thanks for your reply. Sorry mate I know the photos are shit.  Took another photo for reference. Seems the casing does have a hole in it looking on the net, fluid seeping out. Added a photo   
    • Very hard to make out what you mean, is it the squarish hole with redline shockproof (probably) under it? Is that pic from on top of the engine with the firewall to the left of pic and engine to the right? Either way, spray the area liberally with degreaser and try again, maybe circle the part you are worried about
