if you return the BOV to stock catch cans are ok if they don't vent to atmosphere

but yeah if you don't care about the possibility of getting defected then yeah get the GT3076

from memory it is about $80 for a power run

f**k thats not bad. My old tuner for my ford was free for dyno runs ;)

Ha this vents to atmo

Bov has two settings for plump back at atmo

Eitherway cars off road in 12days try my luck at the track get used to it.

But yea just wanted to see what i could push through it last it had 3inch dump n shitty 2.5inch cat n shiity cat back, now its full 3.5 ;)

Then as always build the car the way i want it

The guys at Jaustech and also simon at morpowa are great as well, Heard good things about willall but I have never used them personally. I don't like boostworx as shaun doesn't use ANY knock detection when tuning, if you had a failing fuel pump it would almost certainly result in a popped motor.

I've also had 2 tunes from him that detonated as soon as the weather got above 25c and needed timing pulled out as he set the knock map to be identical to the normal fuel map.

He also doesn't do a road test/tune touch up nor does he test the cold start functionality, every tune I had had to go back to get him to fix the cold start.

Yep rang up said same shit id probs have round the 220rwkw

But il find out friday afternoon ;) 60bucks for a dyno run

Then when they can fit me in for a tune see what i can get to, as far as i know iv got all

Mods to push the limits of the turbo.

If this is 220ish itl take me weeks to get used to 250 or 270

The internals will be fine for that. all depends on what rear housing youve got, if its the normal nissan highflow bill does your outta luck for that kind of boost., id suggest going a proper 3076, 20psi will see you too 300. mine makes 270 on 16psi easily enough

.... Thats a bit shit. I figured garret internals ment around the 20psi region

It isn't about what it can 'handle' it is about where it stops making power. You could probably run 28psi no worries, but whether you'd make any more power than 15psi all comes down to what combination of wheels are used.

Hypergear has them making 270kw with the stock rear housing, though they get seriously hot and he smashes 20psi+ through them to do that. Wouldn't be very detonation friendly.

I'd run 16psi through it, maybe a touch more if you need too

I'm doing a safe 20psi with N1's on a 22 yr old bottom end. Replaced the gasket with a cometic mls 1.3mm unit, arp head bolts, smoothed head face etc

20psi is fine. Anything over that u wanna start worrying. I have the smallest turbo kit avail meaning it pumps less air at that PSI than a big one (ie a t51 can produce mammoth power at 7psi but is quite laggy and needs cams)... but psi is a matter for the tune, the gasket, the rings and valve seals. nothin to do with anything else - psi is all relative to the heat and volume of the air going in after all...

Put short I reckon 20 is doable on a stock engine in good nick, provided hes not running anything large (by large i mean anything that a) needs cams changed, b) is a single c) is bigger than a 2860-7 equivalent. Once you go over 350kw you're getting into the danger zone. I'd be happy if I got 300kw but really, the feel and response of the car is more important to me than any digits on a dyno chart

It isn't the psi that kills motors, hell it is hardly ever even the raw torque that kills them, theres a few blokes running over 400kw on stock engines, it is all down to heat and avoiding detonation, the torque limit for stock pistons is pretty damn high, they will withstand 400kw for quite some time if you keep temps under control and have absolutely zero detonation.

All in the tune imo.

Have the same high-flow 3076 internals from last years SAU dyno-day and pulled 274.7kw on 15psi (smaller rear housing), 220+ this year's SAU dyno-day on stock 7-8psi boost without a decent tune - reason for decrease was engine 're-build' as stock bottom end wasn't happy when past 18psi on a cold-chilly morning and thus replaced with forged internals. Therefore would agree that 16psi is a safe place to start with 'upper' limit.

    • 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
