i would be changing it simply due to age of the pump, but also i think the stock one would be at it's limits.

new fuel pumps are cheap and take about 1/2 hour to install yourself

Ok cool, sounds like I should get a new one! lol

Might get one installed today while its in the workshop.....

My mate said he can get me "JR coilpacks", has anyone heard of them before? Ive tryed doing some research on google but cant find anything. Or would it be best just to get Splitfires?

Best to change it man.

WALBRO fuel pump is like $130ish, very good pump. I think there is someone with an R33 making about 300rwkw with one?

GTR pump is also a good upgrade. Its a similar price to a WALBRO pump, but 2nd hand obviously. There a good size pump and will serve you fine.

BOSCH 040 pump is a slightly larger pump, but worth more like $180. Also a good brand pump good for big power.

Personally running a GTR pump and aiming for about 220-240rwkw which I think it should be fine with.. But I only bought it because I got it cheap.

Would go with a WALBRO if I did upgrade as they are good value for money, just make sure you get an original one.

Just my input, hope it helps. :nyaanyaa:

Oh and just a quick input about injectors. They will be fine to about 215-220rwkw, once you exeed that or get near that its recommended that you change them as they get high into the duty cycle, which means there more prone to failure.

R32 GTR injectors are a good replacement, but for a few hundred more you can grab a new set of NISMO 740cc injectors, about $500-$600.

just think about how vital it is to keep a nice flow of fuel in your car.. change it asap.

i personally wouldn't change your 15 year old standard pump with a 15 year old GTR pump.

if you're really after GTR type, get the nismo pump. if you want your money's worth, get a bosch 040.

change the injectors too. i wouldn't feel safe keeping them close to full load.

that's my 2c :nyaanyaa:

If you dont have ignition problems, then you dont need any.

When you say ignition problems do you mean when i start the car? Becasue everytime i start the car i need to touch the pedal a bit to get the fuel going through? Would this be the fuel pump or my injectors?

With the Coilpacks, i wanna get some new ones as every now and then the car will start miss firing, but then it will be ok for awhile..... Think im gonna go for the JR coilpacks, they are new for $400. Spilfires seem to be $700... bit expensive.... Has anyone heard of the JR coilpacks?

It'll be okay to run your standard injectors at 215rwkw+ aslong as you've got a good tuner. I think it'll be best to change your injectors at 200rwkw though.

Like everyone else has said about the fuel pump, just get a new one. Don't replace a 15 year old pump with another 15 year old pump.

don't start pulling the cash out yet.. try a couple things.

for starters, have you taken off your spark plug cover? with it on it traps the heat inside which can make your coilpacks go funny.

second, try doing a coilpack diagnostic check to see if they're up to scratch.

and third, slap some injector cleaner in. see if that helps.

Best bet would be to change them out before they do go, as the density of compressed air/fuel in the combustion chamber increases, so does resistance, putting more load on the coil packs which will eventually cause them to fail :P

Splitfires are proven to work but they're also a rip off.. If you're handy with electronics it doesn't take long to wire up 3 bommodore coil packs in a wasted spark type setup :(

If you dont have ignition problems, then you dont need any.

      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.
