Turbo X-trail

[StealthX]

This might've been asked already but were you able to keep the A/C?

Nah no ones asked it before!

lol yeh i kept it. Full climate control system works perfect. I had to bend one of the aircon lines out of the way of the dump pipe, but other than that, didnt touch the A/C system...

The only thing ive lost is cruise control due to the mechanical throttle conversion. But I think i can live with that

[StealthX]

Hey guys.

Took the car back to Andrew for a touch up tune.

My car was cruising a bit lean so he put a bit of fuel in those load points, then took some out under load cos it was a bit rich.

As normal its not accepting much ignition timing at all... This is prob cos of the heat that this crappy turbo is generating.

here's the maps of the boost vs power and AFR and power:

*note the wastegate that cant control boost, the wastegate is set @ 6psi, but it rises to 11psi!

its not an issue though cos its tuned for 11psi and never spikes more than that...

So I'm still making 190hp with a blown turbo! haha

I've lost about 25hp from the initial run of 212hp.

The important thing is, its making 140kw at the wheels, where stock it makes 80kw (tested by some guys in sydney) thats still a 75% increase in power over stock

RE: new turbo: I've settled on a GT2860r -7 commonly known as the great disco potato

They are rated @ 180-310hp and ill aim to run 8psi and make 220-230whp or 170kw

Should have it in a few weeks then I'll go back to Andrew (again!) and have another power run

Stay tuned!

Nice man, this is nearly completed! So when is the world going to see this thing in the flesh?

[StealthX]

What ya mean whens the world gonna see it!? Ive bin boosting around for the last 4 months!

I'm planning to rock along to the next SAUWA cruise, im keeping an eye on the events section!

As for whoop ass wednesday, im not too sure...

I just dont have the money to replace things if anything goes bang...

having said that i have been giving it a raping on the street and apart from the turbo, it hasnt looked once like its gonna give up!

So it should be ok for a run or two at motorplex, ill just have to wait till the new turbo is on, tuned and ran in etc...

[StealthX]

Hey guys. Just wanted to put up a few pics of a recent cruise.

Thanks for the photos Rhys!

(yay for the worm turbo bearings!)

[NA_Goodness]

Those photos are fantastic!! Oh wait, their mine The car looks great in person man, you've done very, very well! Well done

[StealthX]

Hey. Update time...

My turbo is well and truly shagged. Blowing more and more smoke by the day...

Not to worry though! Mr. Garrett to the rescue:

That's a 350hp GT2860rs with a 0.64 A/R.

I'm predicting the response and midrange on the QR25 2.5L is gonna be off the scale.

Hoping i can still make north of 250hp on not much more than 10psi.

It's making 212hp on 11psi when it first got tuned, on a tiny, crappy VG30 turbo... Hopefully with a bigger one turbo ill pick up a bit extra due to better exhaust flow, and less charge heat will allow andrew to add in some decent timing as opposed to the <5 deg that ive got atm under load

For the conversion, so far ive got: t28 and 5bolt dump flanges, gaskets, cooler pipe couplers, oil drain flange, oil fitting to fit existing line and GT28 turbo and water lines.

From here all I need to do is:

-rip off the old turbo and manifold

-get t28 flange welded onto current manifold

-get dump modified for 5bolt flange, where a 4bolt sits now.

-modify oil drain to suit new turbo

-install water lines and tee into heater hoses

-source 480009 - 9 (7psi) actuator (stock one is for 13psi - too much for now)

-install boost controller and set to 10psi

-tune

I'll post updates as i get them, cos THIS is what i should have done in the first place instead of this VG30 fail of a turbo...

GOOD Turbo X-trail

New turbo 2871RS?

Good 3076 yes!

[StealthX]

Thanks mate!

My new turbo is a 2860rs

for what i need, 2817 and 3076 are too big...

How are you finding the tuneability of the EMS ECU? you are using the stinger or the 4860?

[StealthX]

Stinger 4424.

I love it. Havn't had any dramas at all! It was a dream to install, got everything working first time, felt very compatible.

Only thing is the electronic throttle fvcked up, but i knew what that was...

Andrew from Hyperdrive has been doing it all, hes the one who recommended this ECU.

From what I've seen/tuned/adjusted its great!

The softwares easy to use, the datalogging more so, havn't had an inch of tune drift or anything wrong tune wise.

That's more a credit to Andrew though...

Why do you ask? I've heard a few ppl bag them out, but I'd use again!

[zebra]

Cool, good to hear.

I ask becuase the 6860 is on the list of potentials for my race car..just gott weigh up whether buying the ECU and then having to buy ignitors and even the loom seperatly is worth it compared to paying a few bucks more for a haltech PS2000 or wolf v500

[StealthX]

Yeah the motorsport series are even better than the Stinger, more features and better resolution maps. the depth of tune is pretty amazing!

Plus theyve got wideband input too, which makes them that much easier a to tune and analyse.

I dont know about Volf computers, i didnt look into them much when i was searching...

What engine is in your race car?

Have a look around some forums and see which computer suits to your engine well, and what others have done...

Most people wait at least a year before they upgrade their turbo Jks mate.

How long will that take to get to get it up and running, man? Hopefully you can get it to Kwinana before they close for winter! With any luck (and my license back) I'll be able to get down there myself.

im hoping 2 weeks rhys...

all i need to do really is modify the exhaust mani and the dump. the rest i can knock off in half a day...

then hyperdrive can do the tuning, thats it!

still gotta sort out a wastegate actuator though, need a garrett low pressure one, not the high pressure one thats on it now...

as for kwinana, im not really that keen until EVERYTHING's 100%, im still a while off yet.

Ok, seriously, is my car THAT hated by everyone or am I going crazy?

I just had some guy (who will remain name-less for his sake - and because i have maturity) just PMd me, and said: (i quote) "you car is gay , im thinking of putting a turbo on my mums car as well ." (unquote)

I didn't know my car was hated that much that someone would go out of their way to express that.

And he owns a GTR too, no shit your car is better than mine, you don't have to exclaim it to the world.

Interesting to say the least.

This gives a whole new meaning to sleeper

Dont worry about those guys...snotty nosed GTR owners are a bunch of poofs anyhow

LOL.

Name & Shame + Report Abuse.

Don't worry about these tossers man, I get it all the time "bunky" - "thats ALOT of work man, not even worth it", peice of shit, my bog stock r33 "gtr" (gtr, gtst, same same) is fasterrrrrz lolz. These morons don't even work on their own cars. Fully sick workshop stickers on my quater panel ulleh, more horsepower.

If this guy had a GTR, or balls, he'd post it, not PM you.

pft, who cares if people say stuff like that. I used to have an Xtrail for a work car, they are sweet!
