Hi all, just wondering how many of you's out there have wound some boost into your cars?

We run 10 pound all day everyday.

What is everyones idea of a safe boost level to run?

Also what sort of fuel ecconomy do you guys get now?

... you's ....

Sorry, firstly a pet hate of mine, it's 'you', plural and singular.

And on topic, i run my bleed valve at 10psi as over that the stock stagea computer has a fuel cut and the car jerks around. not a fun experience.

I'm getting about 350 - 370km to a tank city driving and over 450km to a tank country driving

I've got the jaycar IEBC set at 10 pound on high boost setting. With the stock (well I've got an R34GTT but close enough) intercooler and turbo I won't run any higher than this. I also doubt if I did I'd get much more power anyway. As it is even though my guage only just flickers about the 10 at times I still hit boost cut when I push hard between gear changes (auto).

i'm not having a real fun time with fuel atm as most people here will tell you. If I can get it over 300k's city i'm doing well atm. But I've only just bought it and am now learning how to drive it for better economy (= baby it). on my current tank i'm at 70k's and in between 3/4 and full so its looking better already.

mine is running 11 with the uni chip, seems much better than standard but missing under load, think its the coil packs. getting about 280 to 300kms a tank city driving, but i do have a bit of a heavy foot

It's prob a good idea if you add if you have the standard turbo, exhaust & any other mods.

Mine is stock except for a splitfire filter, & i run around 10, but i find at around 5000rpm it feels like a stutter in the power band & i got no idea what it is?

0 boost for the last 8 months haha, and before that was 18psi with 350rwhp for about a month, and before that it was stock 7psi with the rb25.

soon to run 17-18psi as a base tune, and then in a few months hoping to put in over 2bar and push the t04z to its limit :D

Well currently I'm running 8 - 9psi...

When I get the Jaycar IEBC installed etc. I will be running 10psi low and 14.7 (1 bar) on high.

Fuel economy sucks :P Cant really get over 350 no matter how hard I try

Once I get it tuned properly I want to run about 10 psi, as the stock rb25 turbo's do not respond well to anything over 1bar for prolonged periods, or so I have been told and read on here, (there are thousands of threads on this subject).

But I was getting about 400kms out of a tank, but that was with the pfc tuned with a blocked radiator at the time, so it was tuned stupidly rich.

I have to clean the back screen at least once ever three to four days otherwise it gets blocked by that unburnt fuel soot :(

Hopefully in the next couple of weeks it will be tuned properly on 10psi, and I will be aiming for ~500kms out of the tank, hopefully :P

Q was, what is the back screen? is it just the rear window?

I thought at first it may have been something on the intake causing your fuel rich problems. I suppose I had in my mind what others have said about cleaning their AFM's.

I just wanted to be up to speed with my servicing before it became a problem.

After reading some of these threads it seems that most people have a squeak/rattle or misfire problem somewhere. Everytime I drive mine I listen out for things and have yet to fault anything. (except for the noise in my left ear saying "slow down you've got kids (3) in the back!")

It runs flawlessly and I love it more each time I drive it.

OH OH OH Sorry :D Rear Screen = Rear Windscreen :)

And its the whole back door and rear bar, that whole area gets covered in black soot, but I am sure it is because I am running stupidly rich, I leave a HUGE black cloud of fuel smoke when I do launch it :D

Currently running 10 psi controlled by the IEBC with the DFA tuned (~11 to 1 A/ F ratio) which was as good as we could get it with the standard exhaust. The R34GTT intercooler is fitted but the Magic cat is still in the garage with the 3.25” exhaust. Plus the SITC is fitted, but untuned, it is waiting on the exhaust.

Now that the project R33GTST is serviced, registered, suspended, PFC’d and running hard and fast, I might be able to get back to the Stagea. There is also a GCG ball bearing high flow and a split dump/engine pipe to go on.

BTW, It was pretty useless running more than 7-8 psi without the DFA, the standard ECU R&R mapping made it slower than when it ran 6 psi.

:D Cheers :)

Running 12psi. All fully tuned.

Full exhaust, fmic, NEW oxygen sensor (for best fuel economy), pod filter, sitc, safc, ebc etc etc.

Get over 420km per tank (hitting resevre), with 160awkw.

Great pick up at 5000rpm, no splutter for me - a nice safe tune, rarely do I let it stay at 12psi....... (heat factor = dead turbo).

Got a spare turb' sitting on the shelf.......

my car is completely stock except for the 3.5" exhaust, front mount, and pod filter.

plannin some more mods down the track.

but I don't wanna go crazy.

keepin in mind that this is my daily run about family car.

if my other half had his own way it would have had a turbo upgrade and computer by now.

but in the end it's my car and the foot comes down...

lol....

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me
