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?

    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drive beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
