Injectors Flow Testing

[zertek]

hey guys,

long story short, i have bought a set of 6 s15 injectors of a SAU user, and now it seems that 2 of them are from an S14 and are ever so slightly different. have spoke to nissan and they havent got a clue on how to tell the difference. just wondering about getting them flow tested somewhere around in adelaide?

[mattymagoo22]

what colour are they? yellow pages 'carby and EFI' there should be someone that can flow them for you

[zertek]

cheers ill look them up

[zertek]

p.s, they are all a redish brown colour on top, but have different coloured tips. 4 are grey and 2 are a sorta olive greyish kinda colour. and the 2 odd ones also have different serial numbers on top to the other 4.

don't worry about the bottom of the injector. If the tops, where they plug in to the harness,are a reddish terracotta-brown then you should be right. just as long as they are not purple as they are 380cc stock skyline/s14 injectors. You'll probably find that if you try to get them flow tested they'll want anywhere from $20-$35 an injector as they'll sting you for a clean as well.

sting you for clean injectors?

sounds like the least you should do before installing 2nd hand injectors.

s14 injectors are purple. 370cc

hope that helps

Post up some pics.

Also, there are some tiny codes stamped on em somewhere, check those

[Birnie]

Oh, you already check, now i'd be worried

Someone was asking a few months back about red ones, but they were a alot brigher red than the dull red/terracotta colur of the S15's

Are the 2 odd ones extra bright in red colour?

I think the bright ones were from an auto s14 and were only like 270cc or something.

wolverine,

He didn't say he wanted them cleaned, he said he wanted them flow tested. Buy the time you buy the 6 injectors get them cleaned you may as well have bought new ones.

My injectors were not cleaned before installed. I checked the spray pattern all good, no leaks from the pintle under 60psi pressure, engine has a good idle, AFRs are safe, saved myself a heap of cash got the outcome, I wanted power on a budget, so I'm all for 2nd hand injectors, but thats just my opinion.

Hey I have found someone north of Melbourne that cleaned and tested my whole set of rb25 injectors for $40. Was quoute between $90 and $150 for testing only in melbourne

understand completely. When i first started my project i was going all out, and learnt futher on in the project to only pay for what i need. I was going to go for the nismo 555cc injector option but decided when i dont wanna push anything over 250kw at wheels, the 480cc s15 injectors would be fine.

By the way i have my car in turbo tune at the moment, they are going to flow test the injectors first then tune her up for me. Hoping they are all 480's

In the past I've had Mildren Race Engineering do cleaning/flow testing. Top work; never any problems.

The R34 GTR injectors I have did 480cc at 40psi.

They charge $20-$25 per injector.

i don't see how saving $20-25 per injector (ie. $120-150) is saving a heap of money but if you are comfortable with end result then that's what counts.

you said getting stung for an injector clean and i wouldn't call it being stung. it's just my opinion that if they are handling them to flow test they might as well, for an incremental cost, remove the risk to engine damage.
