Hi

Wanting to upgrade fuel pump in my R33 GTR, I want something that sits in the factory position and clips in like the stock fuel pump does

Besides the Japanese pumps, TOMEI, NISMO, SARD etc which are like $400 + is there any other pump that can use the standard mounting bracket, in maybe a BOSCH model?

Don't mind if it has to be modified 'slightly' as long as it sits as the factory fuel pump does and flows like a NISMO/TOMEI etc

Any help would be appreciated

Thanks

the japanese pumps, nismo, tomei etc are well worth the money. in both of my heavily modified GTRs I used japanese pumps and couldn't be happier. they fit straight in in about 10mins. sure you can hack up your cradle to fit a bosch pump, but the number of times I've seen people fit an aftermarket pump to the stock cradle and then get fuel surge due to improper mounting is insane. considering how important good fuel supply is I would spend the extra few bucks and get a nismo one.

out of the japanese fuel pumps, which do you beleive is the best choice?

they are all much of a muchness. i've used nismo and tomei and hks. if I had to buy one now, I think i like nismo the best. dunno why, I just have an image of them being slightly nicer quality. but in reality there is bugger all between them.

Probably the best thing about Nismo is that 99.9% of the time is going to fit perfectly.

Thanks for that Adam

Anyone put a BOSCH 044 into an R33 GTR tank?

I put one in a 32 GTR tank; I don't know how different they are internally to the 33 tank.

I wrote a tutorial on it and someone was kind enough to take photos, you'll find it in the DIY section

It may be of some help, I don't know.

In a 32:

* It is not a drop-in replacement (cutting/fabrication/adapters needed, but the work is pretty simple).

* It is as quiet as the standard pump was.

* It flows more than enough fuel at ~65psi (something that walbros seem to struggle with).

If you can verify that your aftermarket pump of choice:

* flows enough fuel at the target pressure

* is a drop-in replacement

I'd go down that path. Drop-in replacements are always that much easier to deal with and you can always go back to standard anytime you want to.

Regards,

Saliya

      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.
