Everyone, I am interested in seeing if this turbo really is a bit of a lag monster, or this fella has just set it up wrong. I am willing to put in $10 towards his dyno time with Trent.

If we do this properly, I'll gather the cash and send it directly to where he takes it (Trent from Mercury, or am I on another planet?) This way, its fairly legit. Plus, I ran a $5k group buy a few years back, and made a lot of friends, so you can trust me. Plus, its only about $100 or so.

Anyway, I am happy tpo help out. Its also going to save me thousands if I decide to take a risk and end up buying a turbo that is laggy, or not suitable for me.

Anyone keen in helping out this test?

If we go ahead, I want to know A LOT of info about your car mate so Fill in this form form

Engine:

Intake Manifold:

Exhaust Manifolf:

Cams:

Compression Test:

Fuel:

Intercooler Size:

Pre intercooler piping size:

Post intercooler piping size:

Full exhaust specs:

Dyno Chart with AFRs plotted:

Full Ignition Map:

Base timing:

Type of ECU:

Anything else I Can think of over the next couple of days

I know thats a lot, and maybe it will take you a while to get the ignition timing down, but hey, if you want a pretty much free diagnosis, work for it, haha.

Fill this out please.

I really want to see this turbo tested properly. I cannot recommend it to people (I'm a tuner, and I get a lot of people asking me what they should buy) if its not what garrett claims.

Thanks, and I hope people are interested.

I have answers to all those except the ones that are obtained from the dyno run. Af ratio. Timings etc.

The GTX3584RS will support roughly 850-880HP on a 3.0L (maximum rpm of ~7500-8000) at a PR of about 3.1-3.3 No chance of getting 1000HP out of it, not unless it can be done at a PR of 2.75 and even th

Trent could sort those out for you. Fill in the rest now to give us a better idea of possible restrictions. Whats the intake like, do you have any pics?

Its a avo airbox. Like the custom ones u see in the corner. Steel. Pod inside leading to front of Turbo. Steel piping.

turbo really is too big for your setup ..

and your piping is too small..

When you say x-force turbo back, surely you do not mean an x-force turbo back....

X-force do not make a GT30 specific dump pipe, nor would they make one thats GT30/skyline specific. If your dump pipe is an X-force item, then you have a factory shaped dump... And that means we know what rear housing you have also...

Please confirm your dump pipe and take photos of its exit from the turbo please.. Please confirm who supplied the turbo for you too.

Had xforce dump on standard Turbo. When I changed Turbo avo had to mod the dump pipe to suite the garret hotside. So it is an edited xforce item. Im definately running. 82 garret hot side.

straight away I say ditch the "12psi" actuator and purchase a proper heavy duty "1bar" adjustable Garrett turbo actuator. they cost around $120

should make a slight, but positive difference, to the spooling up of the turbo.

      I'll snap up some photos when I'm back home, in the office today meeting my "in the office" quota. Have 2x Teams calls scheduled in, office culture they reckon.   I've never owned a proper off the shelf sub, I've always made or modified broken ones with Jaycar plate amps and/or car subwoofer drivers. The current (and broken) subwoofer has a proper home driver in it, Dayton driver, thos one https://www.daytonaudio.com/product/118/rss265hf-4-10-reference-hf-subwoofer-4-ohm FS of 25Hz, which is low but not low enough. Yeah, I think they were brought out to the market to compete with SVS. I would love a SVS PB-3000 but they're not cheap, especially after their price hike. From reviews online, it does look like the Tonewinner D6000 would destroy and with good amount of money saved too.

      yeah, that happens too.  I'm really enjoying 4WDing at the moment, seen a few beautiful spots and want to go explore more of this enormous country.  The 370Z got a clutch LSD in it and a track day, great fun.  Getting the back end sorted out really rejuvenated my enthusiasm for driving it hard, the viscous one is poo especially in such a short and wide chassis.  The VLSD unpredictability was more benign in a long and skinny Skyline.

      With my pre/power I use a remote trigger cable(3.5mm jack each end). I turn tv on, it turns both on via ARC. Or, just the pre with the remote or its streaming software, turns on both. Not that difficult at all. Obviously,  you would also want to actually update/upgrade over other factors in your life(bills, family, other hobbies, etc)

      Yeah, nightfall was very "meh". And I'm crap at pvp, so feels like everyone has cheats(it's just my lack of skill). Final shape has been pretty good. New raid and dungeon are pretty good. If you want to give it a go, probably wait until it's on sale. But, as usual, most of it feels very familiar.

      This morning was Kingswood's Microscopic Wars. It is the album's 10 year anniversary this year and we went to see them play the whole album as a special show a couple of months back. Was pretty spectacular.
