what kinda management can this kinda economy be achieved with? i own an auto and i know that the simple fact of 1 less gear means worse economy. it also means i cant use a standalone ecu (eg pfc). im guessing somtthing like a safc is not gonna cut it right?

Mine is auto

lol! best thing is probably just to control your foot!! save the high boosting for the one off, or drag/track :banana:

thats true...but I only drive mine once a week/fortnight at the moment, so I try to get as much fun out of it while I can :worship:

Really, I dont mind the not so good fuel economy. It's the price I pay to keep the stock engine running sweet. With a complete rebuild I would then be able to run it leaner, increase boost etc. I am happy with my tune...uses fuel (runs perfectly clean...no smoke) but knock is kept down to the teens which is what I am most concerned about.

I dont know where you get that idea from. Why would you tune the car to be rich on cruise as well as boost? you only need to run it rich on boost and thats it.

Running it rich on cruise to "save" the engine is just bullshit IMO.

If anything you would have safer power if you fixed it up as your plugs are probly getting close to being fouled with fuel which will only cause issues on boost lol and could cause detonation because the fuel is not burning properly on boost???

A save running engine is a clean tune.. run it rich on boost im all for that.. but not on cruise thats just silly.

hahaha.. so you'd come under the 'once in awhile' umbrella :banana:

unfortunately yeah...even had to get a jump starter kit for it :cheers: I would like to drive it around more but it can't make it into work carpark, or client car park :dry: so it's a weekend cruiser only.

what has running rich on cruise got to do with anything. I never said mine ran rich on cruise. It runs rich on boost (which might be richer than yours on boost) which was a deliberate exercise from the tuner because at 300+ rwkw it is in the upper limits of the stock bottom end. Because I dont drive it much, and unless it's on a cruise it's only in the city so it stop at lights...on boost...stop at lights...on boost. That is where I am more concerned about an almost non existant knock count which is what I have.

I usually get around 450ks on the highway. Maybe 375ish around town. All comes down to how i drive it. If on boost you can watch the guage go down. It a rich at the moment but am using 1000cc injectors and will be getting retuned soon :cheers:

Just wondering, hopefully in the not to distant future i wanna mayb get a slide high flow and some injectors and it should push the car to 250 to 275kw.

Anyway my question is who has got that amount of kws already in a r33 series 2 skyline? because at the moment i can fill my r33 to the brim and i can get about 350 to 400kms to the tank in normal city driving. At the moment my car puts out around 200kws, so yer if i get 250kws + what can i expect a tank of petrol to last for?

Cheers

Adam

ive got 251kw, and i get between 300-400km out of a tank, even with heavy driving 85% of the time i get to about 350km with about 10-15L left in the tank when i fill up.

mine is a r33 s1

cheers michael

230 - 250 rwkw depending on how friendly the dyno is !

hard driving 18 ltrs per 100kms

average, stop start, short trip driving 13-14 ltrs per 100 kms

could possibly acheive 10 ltrs per 100 km but that would defeat the purpose of owning a turbo sports car!!!

unfortunately yeah...even had to get a jump starter kit for it :D I would like to drive it around more but it can't make it into work carpark, or client car park :P so it's a weekend cruiser only.

hahaha.. i have a feeling i'll have to do that tomorrow!! 2 days without driving is almost enough to kill her battery! :P yeah.. sux about carparks :( lucky for me the one i park at is decent! weekend cruiser is good though.. least you appreciate it more!!! :)

When you said you get very bad economy then i assumed you run it rich on cruise because otherwise you wouldnt get such bad economy.

My car is actually running very rich on boost. Its running .79 - .80 's on boost and about 1.0 - 1.2 on cruise.. in afr terms thats 10.8 on boost and 15.5ish on cruise.

rb25's should get good economy if tuned correctly. at a min 350km's to a tank.

hey mate you seem to kno what your talking about lol would you use a slide high flow turbo?

Sorry to hijack! Anthony will answer shortly I am sure!

I use a slide highflow... it was a temporary answer for more boost until my Garrett was installed....

Slide highflow ----> highly recommended. I achieved 262rwkw @ 16psi out of it (278rwkw @18psi ringing the neck of it to see what the max power I could achieve with it)

Regarding fuel economy... I also use a different ecu to a power fc but mine is tuned as Anthony mentioned - where I cruise at on the F3 everyday and around the central coast is set on close/open loop (never remember which is which!) sooo unless I am boosting up all the time, I will still achieve my 450-500km per tank.

excellent so for $1000 dollars both you guys would recommend it? excellent i think ill go that way for sure then... and hopefully get it tuned so ill easily see 400km a tank!! thanks mate... just how long did you have it on your car for? No problems?

    • 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.
