hi I have a 89 r32 gtr.

Like it says in the tittle i am chassing around 300 to 350 kw at the wheels. I have 2860r-5 turbos and wanted a descent fuel set up to support them. I have just purchased sard 800cc injectors and was wondering what fuel pump to use. At this satge I don't really want to make/ buy a surge tank but i am more after a good intank fuel pump. I have being doing a bit of research, though it has all conflicted each other.

What are the Bosch 040 good for or a 044 mounted in the tank (hp/kw wise) Or can somebody give me another option. I don't want the pump to be maxed out at the kw I am chasing

Cheers

Thanks to all the people who have replied to this.

Is the Bosch 040 good for 600hp or 400hp? I don't want the pump to be maxing out at around 350kw. Is any body using the 040 in a gtr with similar power figures to what I am chasing?

Cheers

according to the specs (4.7L/m) that nismo state for the gtr pump it will out flow a 044 but what it doesn't say is if that is free flow or with pressure.

i just put a 044 intank (R33) and you can barely tell the difference noise wise between it and the stock pump, i used 3 pieces of 25mm fuel resistant PVC tubing opened up and wrapped around the pump and the arm it mounts too.

will nismo in tank support 380awkw?

Put it this way. Twin RS's at anything up to 2 bar on a 2.8 litre stroker and im fine (Fuel pressure gauge in cabin to confirm). Your turbo's are smaller so you will be sweet!

yep, no question, nismo pump is the easy winner. it mounts properly in the stock cradle too which is a problem with other pumps. if they are not mounted correctly the pick-up can be too high resulting in fuel starvation. and the nismo pumps are 276 litres per hour, rated at 3bar (ie stock base pressure).

hmm deff sound like the best in tank option for no dicking around, need to source one now...

i got a bucket of dead walbros... want some spares.....

And my walbro is relagated to lift pump duties upto my surge/044 setup as it couldnt maintain flow above ~50psi rail pressure.

I'd be interested to know what setup a Walbro makes 380awkw with :cheers:

Snowman was/is using a stock R34 GTR pump for 380rwkw, so anything aftermarket is gonig to meet that easily enough

    • Good luck on the weekend mate
    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
    • I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
