for 500kw at the wheels......

usually thats 2 Bosch parrallel fuel pumps.

Swirl tank

SX adjustable Fuel regulator

Apexi Power FC

1000CC injectors

Fuel system should use braided hoses

HKS fuel rails can handle this type of demand easily

heres a typical set up.... but this is just the fuel system, you need an efficient turbo, intercooler... adjustments to the air flow systems.

Decent drivetrain... usually 500kw gives you about 9 - 10 sec on the quater mile

Also keep in mind that a setup like the one pictured has more money in fittings and braided hose too, something that people don't realise until their jaws drop when at the checkout counter!

And don't forget with that much power you'll be shearing 3rd gear like no tomorrow if driven hard!!

Here's another one FYI;

(R32 GTR)

-044 intank (lift pump)

-Twin 044's mounted on surge tank (undercar)

-Twin entry fuel rail

-1000cc's

-Adj FPR

-Earls fittings, lines etc

-Original supply line can be used as return to surge tank

As mentioned above, fittings will be a suprise.

The surge tank also is foam filled and has internal baffles. Basically fuel in that car isnt an issue.

he could be rich for all you know dude..

so this may just be a cheap excercise to him... who knows... not many people on here jump straight to 500KW at the wheels...

Im located in Sunny Auburn... where all the Broz and da Habibz live and the Couzzz as well...... lol

The swirl tank is also called a Surge tank.

here is an interesting article on a DIY surge tank

http://www.ratdat.com/?p=168

as per your request... Fuel system works with the surge tank with pump... here is a Schematic diagram on the run down and which way things flow.

http://www.sdsefi.com/fuelsys.gif

in my picture.. the fuel pumps you see...

The bottom side, where you see a Big Nut shaped bit is the INLET... and the one with the electrical terminals is the OUTLET.

as N1, mentioned...there are heaps of ways in doing things.. but this particular vehicle set up ive displayed was actually on an R34 GT-R done by a very reputable tuner in sydney

Croydon Racing Developments...

it was running Over 500KW at all 4 wheels, HKS 25/40 turbochargers with internal wastegates at 2.0Bar boost. with a 4-plate OS-Giken Clutch & Hollinger gearbox...

it has acheived 9seconds on the quater mile.

be wary at 500kw..... the stock engine internals will fry..... the GTR R32 gearbox is said to cope up to, 500kw...

hope this helps

cheers

Yeah agreed, although having a lot of money doesnt make parts cheap, just means less to that person. :)

Also, the more wealthy people i know are "tighter" than the average income people i know (to generalize) :)

Anyway, thats not the point, all the info in this thread is enough to build a capable fuel system, but i agree not many people go straight to that sort of power, hopefully this thread wasnt starte by someone on school holidays :)

well yeah...

the cars fuel system ive pictured was an R34 GTR... it had a Nismo Z-tune bonnet from japan which costed 10,000 AUD$

so whoever owns this car has money... or he could be just living like a SCUM or living with his parents and blowing every penny on the car.

i would personally never buy a bonnet that price...... but to some people ...the likes of DEMIR.. 10,000$ could be 1 cent in comparison to him....

yeah well he still hasnt told us why he is researching on this...

how much power is the stock R34 GTR box capable of handling?

well not alot has been said about the 6-speed getrag on the BNR34

but generally "700Hp" ..approx 500 - 550kw is about the safe limit, anything over that..there is just no telling

      Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      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.
