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 :)

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 :banana:

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 :banana:

Stay tuned!

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...

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: 23659_415684987904_526132904_4767179_1362572_n.jpg

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 :cool:

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...

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!

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

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.

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.

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
