S15 Sr20det Injector Details Please .

[Birnie]

When i got the 2nd hand ones, they came still attatched to a SR20 rail so i have som idea.

Bottom up (from plastic packages pic)

4th - the little seal on the bottom of the injector

3rd - the big seal near the top of the injector

2nd - these little squarish ones fit over the pin on top of the injector and the half moon/2 screw/metal bracket thats screwed to the rail, holding em in place presses on this to hold the injector in...so the metal doesn't actually touch the injector. (check a pic in the DIY/changing injectors thread)

1st - I have no idea, just came with the batch ??

Oh yeah, the 'squarish ones fit over the pin'.... they don't see any fuel or any rubbing and I see no reason why they would need replacing.

If someone finds out what the top ones are, i'd love to know!

Can't see anywhere they'd go, unless it's somewhere between the actual rail and the engine.

[Birnie]

Just to bring up some more info i found out from 'Dale FZ1' cause he is the 1st guy I've found that ACTUALLY HAS 'EM INSTALLED !

Facts :

1) They are 450cc (as Dale used the correction value based on 370/450 to get normal results from the PowerFC)

2) JapSpec doesn't matter, as long as it was manual, Aus is OK. To be sure just check the colour.

(Just to be sure, Auto S15's have the purple ones, equivelant to the standard R33's so forget them)

Anymore info I'll be sure to add as i found out..

Catchya guys

[Birnie]

OK, I've installed them yesterday.

Took about 4 hours for completely out/replaced/and back in.

Used DaleFZ1's settings of 82.5% and 0.12 latency.

Crossed fingers and turned the key.

It started as if nothing had changed! Was pretty excited

Took it for a drive, all good.

Gave it 2/3 boot and watched the knock, only hit 12 which is pretty much normal.

Couple of piccies below.

You can see 2 stained injectors and one clean injector in the rail.

That's 2x2nd hand injectors and the start of 4xnew injectors.

[mattymagoo22]

i figured the latency to be -.06 got the same 82.5% though.

528 - 584= -056

but if it runs fine no probs eh

[Birnie]

So you've entered -0.06? (negative)

I've got + 0.12.

I had calulated your result too, but Dale already had it working on his settings so i wasn't going to argue.

Is you car running with these setting?

I wonder what difference it makes in the long run?

Anyone know?

C'mon Nismoid!

[mattymagoo22]

runs fine. the calcs ive made are right though don't know how he got +0.12

[Risking]

S15 manaul injectors are that browny colour and are 440-450's depending on rail pressure.

Autos are the purple ones are are 370's same as the redtop turbo SR's

NA SR20's had red injectors and from memory they are 320's or something, I cant remember off the top of my head.

[Birnie]

I've changed my settings to '- 0.06' from +0.12 and it seems to be exactly the same....on start up only though, haven't driven around on the new setting.

Still wondering how much difference this setting is going to make...???

Anyone??

when u confirm pm or let me know and ill add inj settings to PFC FAQ

[benl1981]

Did you have to take the plenum off and everything?

If so did you reuse the inlet manifold gasket?

4 hours isn't too bad.

Did you flow test the old S15 injectors? Before and after cleaning?

How much all up did the new injectors cost you? Including the pump then?

Cheers

[mattymagoo22]

latency i assume means the same as latent which is energy used that cant be measured i figure it to be related to switching on and off if it works i guess it fine.

as for removing injector rail took off intake pipe and throttle body got it out make sure not to lose rail spacers and intake manifold orings

Hey Paul,

Going buy the chart i linked on page 1 of this thread, they are definately 450cc at standard fuel pressure.

82.5 is resulted by calulating on 370/448 just to make it a smidgen on the safe side if anything is wrong.

Otherwise it would be 370/448 giving 82.0

Probably much of a muchness really.

Latency - I'll get back to you on that one.

Both setting have the car starting first time and humming beutifully as if nothing had happenned and that using "positive 0.12" and "negative 0.06"

I bought the newies with the pump for 25000 yen, about $300 at the time using Slide Auctions.

And the other 4 were $250 from Aus delivered but hoping to sell the other 2 of them to someone and recoup some $$

If you're buying all of em 2nd hand, you should be able to swing it for around $350ish for 6 i reckon.

Someone scored 8 for $400 on here! Lucky sod.....

Jump on a SR20 site and search there. They pop up every week or so.

Didn't end up cleaning them or flow testing! Haha.

Spoke to one guy and he was a bit gun-ho and had the attitude of "F**K IT, just throw em in see what happens!"

So i did.

My old injectors are nearly 10 years old and haven't missed a beat...and they were HEAPS dirtier than the s15's when i pulled em out.

The 2nd hand s15 were out of a 2001 model so thinking of it that way, only being 5-6years old, i was going to hold on to my $100.

And really, how often do you hear of people on here with injector problems, i can't think of 1 ! But it probably happens.

So far so good

[Birnie]

..and i didn't crack the plenum open.

I used this DIY thread : http://www.skylinesaustralia.com/forums/in...howtopic=140970

[benl1981]

Thanks Birnie.

Sounds very doable.

I wonder how much all the seals cost from Nissan..I guess you could just order all S15 seals..

So what seals do you think are necessary to replace from your experience. I see you had 4 seals per injector was it?

Cheers

The main seals i used only cause i had em but really, don't bother.

I used the 2nd hand o-rings for the 2 x 2nd hand injectors.

Didn't bother changing any of the top rubber thingos, the ones under the half moon cover.

[benl1981]

Hey lads,

I got the first lot of 4 injectors, getting the others this arvo.

Just a question around the plastic area it appears the plastic has been damaged a bit. Must have been when they removeed them from the rail. I have shown using somebody elses pic where the plastic has been damaged.

Is this an issue at all? I thought they were held in with other brackets..

Thanks

[Birnie]

Yeah, they might have levered em out with a screw driver, i did

Just got to be gentle and patience and pop, out they come.

The owner of yours may have been a bit rough but that hole in the plastic doesn't serve a purpose anyway

they are held in by the half moon bracket which pushes straight down from the top, you should be right.

getting another set? I have 2 spare.

What did you pay?
