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

    • Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes 
    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
