This thread is now delivering f**k yea Can we have a dyno graph with a single, twins and a third axis for bench press weigh for comparison

Twins on a RB will always be shit, all of a sudden the Muricans and Canadians are experts with RBs.

Look guys, I'm the guy who had the white 34 with 2863's in -5 housings, it made 489kwatw but at 33psi. It was a mental track car, I actually never got a proper time with that power figure on new tyres

here are some pics of a local newcastle engine builder & his latest project.

gtx snails with a few other goodies...take note of the intake plenum & flux capacitor. absolutely awesome fabrication work!

Hey Marko,

did that engine or intake and cylinder head come from VIC?

some very familiar parts on there ? :)

I'm just about to do a cartridge drop of a pair of GTX 2863's into my -5's next week with the modified front -5 housing, I have seen GCG have said it wouldn't work? but I'm pretty sure you can't go backwards than having plain -5's.
I am running this on an RB28 HKS engine, and was even looking at the 2867's, but I'm not very confident I need the extra power, and the response would start to suffer a bit.
My -5's have a slight oil leak developing and this is the reason for the change, but I was worried about the 2" -5 housing as opposed to the 3" one on the complete turbo, do you any of you really see the benefit of changing the whole turbo over when the -5 mods looks very viable, especially with a drop in type approach by comparison?
It looks like status saw some good results from this approach, has anyone else done the -5 rebuild with GTX cartridges?
I seriously this needs to be looked at, because it would be great for people with -5's to upgrade far easier and cheaper than the other way.
Sean's job looks great though, and would be the other way I would do it with a complete GTX item, bar the exhaust housing.

Just got my car back with the GTX2863's in my -5 housings, and it is heaps better, I have 30psi with 638hp at the wheels on E85 now, and the response and power in the mid range picked up heaps.

Cams are now 272/ 9.7's I would probably go back to 260's for a perfect combo, but even the big overlap with this GTX upgrade it feels pretty darn near perfect for response and power. I went to the track yesterday, and the corner exits were pretty much bang on, even with 2nd gear short shifted into 3rd it still had plenty of mid range to keep it pulling really well.
The green graph was the power level I had last time, and now this is the new figures. I unfortunately had coil pack failures on the 3rd lap into my day, and the power level had to be dialed back down. I was trying to break the lap record for fastest street car record in QLD and I only had 2/10's of a second to have it. With the extra 80hp I was sure to have it, and the laps where everything was fine, I was driving pretty carefully whilst monitoring temps etc from my recent head gasket change and turbo upgrades. I am now selling my car and don't know if I will have a chance to try again. The potential for this thing now is truly getting crazy, it has been an amazing car.

      R33 GTR running -9 with no tune

      You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.

      Definitely a hearty eater when we go out, I consider these meals my cheat day as I've been watching my calories in and calories out pretty hard since my little fun size stroke, I've gone from a fat boy of 89 Kg, I'm only 165cm tall/short, down to a almost semi lean 73 Kg over the last few years, I'm currently around 17% body fat which my doctor is very happy with, but, my goal is to slowly get down to and maintain 15%,so yeah, I want all of the protein, carbs, fats and sugars when I go out for a binge

      There was a great one on Victoria Rd in Gladesville too back in the day. I can only assume GTSBoy is thinking of the mill up on the wollondilly, no restaurant there any more but they have restored the original steam engine on site and run it every few months, have an annual steampunk festival etc @The Bogan, you came to the wrong town for restaurants. we have a few reasonable asian and indian options but the Paragon is as good as it gets otherwise. That brewery is apparently just opened, been meaning to give it a go some time. The Highlands have plenty of fancy options but I suspect you are more a hearty eater than fancy eater
