Hks 2530 On An Rb20

[RBLUV]

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

Nismo 555cc would be fine. Yes they will need to be installed with a tune.

thanks mate, anyone else got any recommendations?

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

480 or 555.

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.

what bout rx7 injectors.. i read they are more compatible 4 rb20

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
