why do you want 550cc injectors for your NA? do you have an aftermarket ECU to run them?

and that wlabro pump looks too cheap to be genuine

lol took the words right out of my mouth.

may i ask why you want to upgrade them? is the old pump failing? if not then don't bother. neither a bigger fuel pump nor injectors will give you a power increase. unless you have a hell of a lot of work done (such as having a turbo fitted) then there is no need as you won't even be close to maxing out the stock ones.

Does seem a bit cheap for a Walbro. A Walbro GSS342 should be a direct replacement (done it on my R34 GT for the turbo conversion) but as mentioned already, why do you need bigger pump and injectors?

GTT Injectors are a straight swap on an RB25DE NEO. iirc they are around 370cc? which is enough for me to run a turbo at around 10-12PSI on 10:1 CR. Unless your looking to rebuild your engine, put on a big turbo, one that would even require ditching the factory AFM... you're not going to need those size injectors and even then a Walbro GSS342 is good for 500HP (or is it 550)? nuff said though, spend the money elsewhere unless this is part of a major upgrade :)

well im thinking of getting an APEXI fc +hand controller for my car... thats the reasoning behind it..

also anyone know who/where i can source one of these apparently they have been discontinued for the ER34's ?

Apexi Power FC should be fine as the car is manual and no longer needs the auto shift logic, and your replacing the ECU, not running a piggy back.

What are your long-term plans with the car? You would at least want to be working on the internals, upgraded camshafts, port polish, raise compression etc... to really take advantage of 550CC Injectors, bigger pump and a PowerFC... The cost of the PowerFC + Tuning = not worth it unless your at least fitting a snail

In that case buy your parts, but wait till your ready for it all to be put together before you start playing around with ECU's injectors and pumps. Only because it's unnecessary costs in labour and tuning, only to be retuned on the turbo conversion.

So to answer your question, a Walbro GSS342 is a direct replacement fuel pump, and R34 GTT Injectors will be a direct replacement, and will be plenty unless you want to go all out rebuilding your engine for higher horse power. Unless your able to get R34 550CC injectors at a really good price that's hard to pass up, then go for it, otherwise just stick with good 2nd hand GTT Injectors and you should be fine :P

      Mistakes were made, my R34 Story

      Yuck. But it's kinda the same principle, moving timing around to make car run bad but sound good.... I went for a more spirited tuning drive to iron out a few things. Car no longer stalls, and it loved to dip RPM low when you clutch in. After tuning this (and the 4-5 tables that HPTuners/LS1 OEM ECU wants for idle air correction) it's now behaving somewhat normal. All expected because there's a new TB, new Intake manifold and that new TB which is 102mm vs 78... has an entirely different IAC passage which is smaller because ????? Unfortunately at this point I went to make further fine tuning changes to avoid it flaring up, you know... _tuning_ the HPTuners dongle died. Well to be more accurate - The USB cable died in a fashion that anyone who has ever charged a phone will recognize. After the app demanding I resync it 50 or so times (which all 'succeeded' but all failed) the device does not want to sync and I've logged a ticket with support to see if it's fixable. US Support said it was a 'storage issue' but after removing the SD card inside it and formatting it/fixing it the issue does persist. Unfortunately usually the fix is "Turn in your old dongle and pay $700 for the upgraded one" it's cheaper because I get some free licence credits I unfortunately don't need. However I'm 10 minutes down the road from HP Tuners AUS/VCM so at least I won't need to post it, and logged a new ticket for support over here. Definitely drives different. My SOTP dyno believes it's probably making 310-320kw instead of the 280 before.  It scrambles for traction a little now whereas it previously different. It drives like a bigger cam car up top even though the cam is smaller, likely due to the cam not being advanced 6 degrees. The timing is deliberately low and the fuel is very rich so who knows if this will improve on the dyno. It may, imperceptably. Also funny is removing the pineapples definitely makes the car squat more and axle tramp less. So this behavior of having more top end, squatting more, and scrabbling for traction more makes me think = more power. But I could have just been sitting on the threshold of that kind of behavior before. Time will tell if my butt dyno is calibrated right. I need the exhaust leaks fixed before dyno tune for obvious AFR related reasons - I repositioned the pipes but I'm not confident it's fully sealed even if it is better. At least the car does drive around while I cannot tweak/tune it for now. And I have aircon again. medium success!

      I need more than help to finish my R33

      Don't use that manifold. Please don't use that manifold. Sunk cost fallacy is not worth the later pain. None of these will be relevant to the change that will come from the different turbo and manifold. As in, the effect of the exhaust will be nil, regardless of what else is changed. And all the cam and fuel system stuff is not changing either way, so has no effect. The turbo and manifold (and to a small extent the wastegate)....big change.

      Just wanted to say thank you for your input   my man (lead mechanic by trade) and I have done a heap of work as you can imagine just to make the hot side work with the dump pipe, stupid massive intake on turbo, trying to get the waste gate on was not fun.  I’m kinda getting to the point where I don’t know if I try and make this work and not throw all this cash and time away or do I scrap the lot and start again? the Apexi I’ve got was tuned for a few slight differences:   Tomei pon cams (mine are stock neo) Turbo smart 38mm external waste gate (mines 45mm replumbed) with stainless screamer pipe  3inch turbo back exhaust with high flow cat Sard 800cc top feed injectors Sard adjustable fuel pressure reg

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.
