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.

Edited by PSI-FED

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

    • What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day  
    • While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.
    • Are you 100% sure this isn't tune related?
    • 140-150 across the board. At this point hoping the grounding harness fixes it. My grounds are all tied to the chassis and none to the battery. For SR and KA that’s never been a problem for me but had a few other guys here and Reddit who told me RB really like a very solid ground setup tied to the battery so going to try that next, I’m stumped if that doesn’t do it. Never had a car have spark and fuel and not fire off before. Only thing I can think is the spark is intermittent/weak because of grounds nothing else really makes sense at this point 
    • I am having close to the same issue. Can you help me with what wire you grounded to get your pump to trigger?
