I have searched, perhaps my skills in doing so aren't quite up to scratch but have done so regardless.

http://www.skylinesaustralia.com/forums/topic/218752-nismo-fuel-pump-for-32-gtr/

So I plan on using a Nismo pump in a 33 gtr, to my understanding, they flow 276L/h @ 12.5V

Stock wiring to fuel pump generally does not see 12.5V does it?

Therefore I'd like to know if it is just as important to rewire for the Nismo as there was no answer to

a similar question in the above thread.

Regards

Michael

Absolutely. Run a new wire from the battery and a relay. Make sure the wire is 6mm and just trigger the relay from the stock power feed.

Thanks for clarifying, so it can be done exactly like so on an R33 GTR right?:

It's a little bit confusing because the below diagram seems to teach a slightly different method (or is it the same?):

Is there one method which betters the other?

The former (NARVA relay) seems easier.

When i rewired the fuel pump in my 33 GTR (nismo unit) i rewired the WHOLE thing. I got rid of the fuel pump speed controller, ran new earth and new feed and relay with a fuse in line, cost me about 50 bux in parts(heatshrink, solder, relay, inline fuse holder, some QUALITY terminals)

No I mean the diagram just looks like a standard 5 pin relay setup. Nothing special.

Or was the purpose of the diagram to explain how a relay is wired?

Oh yeah just to put it in a drawing. I found the DIY a biit confusing (where its just written) so thought I'd do a diagram that shows how to do it with the R33 wiring. Its a basic circuit but might help the OP. Only problem I had figuring it out was working out the positive feed because I didnt have anything to test it so just made up a test light. And yes forgot to add the fuse in. I have a 20amp fuse between battery and relay Edited by 89CAL

      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.
