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!

      Rusty roof repair

      Some of the filler.   Also if I look under the top flap of metal it starts looking good quite close to the edge. I get the feeling it doesn't go much further.

      Rusty roof repair

      By PranK · Posted

      So, I finally started digging at the bit of my roof that was cracking and bulging a bit. Well, it was just thick filler that was covering some pretty bad rust. I didn't find the edges, I was too bummed to keep going.  There are a few holes as you can see. There was just so much filler but looks like no attempt under the filler to prime or use rust converter, just slapped filler on exposed rust.  Anyway, I'm going to take the windshield out and find the edges. I'd love to fix this myself as I'm pretty sure it'll be expensive to get done properly. I was thinking I could just get a cut piece from another E39 and just weld it in place as it would be the right size and shape.  Thoughts?

      This is the territory of the "Stage 1/2/3 Golf GTI/R" or otherwise off the shelf tune with (relative to before) minor mods. It's easier now. Downpipe and Tune and boom, big increases. Stage 1 OEM+ is where it's at. This is where the niche evolved into and it's really easy to see why. It's rare to even NEED to consider changing turbos or going to aftermarket ECU's or building bottom ends for more power. Stage 1-2-3 will get you a LONG WAY. Civic Type R turbo GR Yaris/Corolla Anything with B58 (MKV Supra/x40i) Anything BMW in General Anything Audi in General Any turbo AMG RenaultSport Turbo offerings Korean Elantra N/I30N Ecoboost Mustangs Focus RS? List goes on. I would argue in the future it won't even need to go on... M3P is pretty rapid out of the box...

      There is a way, but it's not with the same cars. You need to find the same vintage of car, that we had. Realistically, that was an affordable car with aftermarket parts around. So what people need to find is a car that had a decent base in its day, and can be modified. They're looking for a car year make of 2010 to 2015 really... Aus could have done it if Holden didn't fold as V8 commodores were cheap, and if Ford didn't get expensive thanks to COVID, then you could cheaply play with FG Barras. Realistically, those are just a bit heavier, four door skylines. I'm sure the US and UK have similar cars they could find.
