Hi Guys,

just wanted to know what is teh difference on the turbos for GTR33??

I was looking at this one below from ebay; http://cgi.ebay.com.au/R33-GTR-Turbos-N1-Steel-Turbine-RB26-R32-R34-changeover-/120487485104?pt=AU_Car_Parts_Accessories&hash=item1c0d9d1eb0

R33 GTR Turbos N1 Steel Turbine RB26 R32 R34

and comparing to the -5 or -7

my aim is to get about 300kW on standard engine, power FC, adj cams and bleed valve....atm it is doing 265kW

help me guys, im confused....reason i want to go with the "R33 GTR Turbos N1 Steel Turbine RB26 R32 R34" is because they are cheap.....

Mind you to get a set of -9 with actuators you would be looking at $2700 being more than double the $1250.

Sure they might be a bit laggier than stock but I would think they could put down around 280-300rwkw without too much hassle.

I dunno I am curious too hear about these. I have a set of -9's waiting to go in but I was seriously considering these initially.

When could you expect 1 bar boost with these? around 4500-5000 rpm?

Basically -5 response (4500rpm before anything really happens)

With -7 power

Pretty poor IMO when the -7s are on almost 1000rpm sooner

1000rpm less response with 60-80rwkw less… The extra 1500 is worth it. Best value for money modification.

It’s also power delivery in/out of gears as well. Not what it makes on a loaded up dyno run.

Hey Ash, you always seem to know the g-o with forced air induction. I'm currently getting my 31 worked on at Chasers. It's a stock RB30ET using stock intake manifold, getting a new GT-3586, 45mm ext. wastegate, 3" exhaust, running a gtr cooler (not sure exact dimensions but big). I know i'm going to be making good power but what sort of spool time / response / lag do you think I will be looking at?

Cheers,

James

have a look at calaisturbo.com dude, that's pretty much the standard combo over there ;)

been 8years since I've really looked at 30et results.

stock exhaust manifold and cams will be your issues though with that turbo/motor combo. you need a bit of cam to get the ole SOHC working with a 35

Ook, cool, cheers. I didn't pick the turbo as I have no idea.....also getting ecu and fuel upgrades atm......plans to DET in future with 30 bottom end.

Not even sure of the turbo I blew up (bent shaft), people told me it looked like a factory 33gtr. Used to be spooled up @ 2000rpm in 2nd, 2800 in 4th, and pulled quite hard at 14lbs to redline, where possible, within limits of course. So quite punchy, and nice to drive. I'm worried it's gonna lag like a pig atm, but Chasers think that it'll be fine once tuned.

Thanks for your input.

Power vs lag = it'll be laggy with that turbo. No two ways around it regardless of what people tell you.

You can't bolt on a 700hp turbo and expect response :)

If you had some head work, cam, exhaust manifold and a 3.5-4" exhaust you'd make 350-370rwkw and this would obviously offset the lag in that respect. However my stab in the dark will be 300rwkw depending on how much boost can be wound in. Which is what a 3076 would have done :)

See how it goes either way.

Sweet, will do. If all goes to plan, you should see it next Sunday, providing its all together by then. The Haltech Sports 2000 is in and wired up, just stuffing around with cooler, exhaust & dump pipe, then tune. Worried that clutch won't hold up for dyno tune, if so my car wont be there.

Hey mate, did you used to hang around reservoir in the last couple of years. I have seen another orange 33 looks identical from what I remember. Haven't seen the car in over 18months. Not sure what the plates were, but basically, used to 'CR33M' every time I seen it. Coincidence? (havent seen any other orange 33's)

Wasn't me mate. There is some guy up there that has a similar looking car to me. But think he has a top secret kit, no carbon lip spoiler and had a orange bonnet.

      I did not go to GTR Festival. It's quite a long drive and the car wasn't dialed in yet. I also wanted to see how the racing portion went before going. From what I can tell the classes were not heads up, index, or bracket - just whoever has the quickest ET wins. Never heard of that sort of thing before and maybe some people like it but it's not my cup of tea. I don't suspect I'll go if that is how the racing is done. I did get the car out three times and had issues each time. Some were my error - haven't raced the car in over two years - and others were parts. Had trouble getting the clutch to slip correctly and remembering how it was set up in the Haltech. Broke some drivetrain parts as well that couldn't be fixed in a couple days to get back out. Season definitely didn't end the way I wanted but at least the bearings are still fine! Not a fleck of material in the filter. Really hoping next year is the year I can actually test this car properly.

      find it funny everyone claims different fuel chains, do different things with their fuel blah blah blah. We don't have that many fuel terminals in Australia. The fuel tanker trucks drive into the terminal, fill up, and drive directly to the service station and dump out. The majority of fuel you get, is coming out of the same terminals. The variation is actually at the individual service stations and how good their tanks are, as well as how much turn over they actually have. Older fuel stations, that haven't had their tanks replaced are going to end up with the worst fuel. Also a lot of older stations have shit design, and shit maintenance, and end up with more water absorption into the tank. This is when you then get a bad batch of fuel. Other shit things happen, like tanker drivers have a f**k up, and starting to unload the wrong compartment on their truck into the wrong tank.
