Car in for service - two of my injectors are leaking fuel on R32 GTR.

I can either:

- replace two buggered with 2nd hand stock 444cc

- replace with 6 nismos

- upsize to bigger injectors

Nengun has a deal on SARD 700cc but I don't know if 700cc injectors will be usable in my car

Car is only lightly modded GTR (HKS pods, cat back, restrictor removed) makes about 170KW at wheels.

Advice please?

I have a new Power FC in the box at home - will fit it if I have to, but kinda like the car the way it is.

:P

Any advice gratefully received.

Depends on where what level of mods you want to do with your R. If you really are happy with the present level of performance, perhaps consider getting the leaking injectors repaired/diagnosed at a specialist injector place and then getting all cleaned and flow tested.

If I had a "spare" PFC, I would certainly be getting this fitted and tuned ASAP as it offers good "bang for buck". Consider fitting adjustable cam gears at the same time and you will be amazed at the performance increase for the moderate cost outlay. Standard injectors will cope with this power up just fine.

Why bother wasting money.

Stock GTR injectors can support round 300rwkw. Replace the 2 stuffed ones with stockies..

But i would definately hook up that Pfc and get it tunned, it would be a different car when you get it back, especially if you turn up the boost a little :cool:

i've got 650cc sard injectors in my rb20det

got a highflowed r33 turbo in it, works fine, 700cc injectors in a rb26 would be ok i'd imagine because the powerfc is pretty good at controlling big injectors

also if you are interested i have some brand new 550cc nismo injectors that i never used, i bought them for my car but ended up going the sards instead. pm me and and i can do you a good deal on them.

xfixiate - you will be totally amazed at what a PowerFC will give you over the stock ECU.

Also with an adj cam gear... it'll be a totally different car

Smoother everywhere, more power to boot.

Personally just buy some second handers, and reco all 6.

However, If its going to cost more than $600 for full reco of them all, i would just spend the extra few bob and get some 555 Nismo or similar.

You dont needs 700's... thats overkill.

I think you're right.

Two second hand ones are going to cost me $100.

Prolly another $150 to get them cleaned. And $20 in freight

So $270 to reco old ones. And assumes I have no more problems.

I should be able to get around $200 selling the existing set.

Nengun wants $640 for 6 brand new SARD 700cc delivered. Little more for Nismo or HKS.

So $440 real cost.

Or, $180 gives me new ones. Damn stupid not to buy newies.

HOLD THE BUS

can we get the moderators to DELETE this post

if word gets out that this guy has a GTR with only 170kw at the wheels (and he's happy with that) - I'll have every noob in a modified WRX lining up with me for weeks :)

Seriously - I'm seeing 280+awkw with std injectors and a PFC in my R32 GTR (I'm on their limit tho) Get some 2nd hand 440cc units flowed and test and you'll be good to go.

BUT - if you want to take advantage of the Nengun offer – and get the 700cc Sards – I'll be more than happy to do a swap with you ;)

Also – I agree – get that PFC installed. You'll jump to 220+awkw over night. It WILL transform the car and your driving experience (no down side)

ahhaha, evan more the reason to leave it... then you can go chop chop scoobiedoo.

pfc, 700cc injectors is nice. youd only have to get them later. sooo giddi up..

wont have any adverse affecs. just hooke them up. :D

besides stock injectors on 14-15pounds are at 90-95%duty. (no point having sequential injection)

(with standart turbs)

But, doe't injectors have to be matched sets?

I mean, if the other 4 are worn, won't the two new ones create an imbalance?

Oh bugger - how can I tell what injectors I have now???? they might not be stock or genuine??????

If you flow test the 6 you're going to run and fit the PFC, you can adjust the relative flow of each injector based on the test results.

Install the PFC man!

      What should I do next to hold the head on

      Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.

      Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.

      Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?

      1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
