Turbo Difference.....

[lav]

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.....

[R31Nismoid]

They do not compare to -7s or -9s simply because they are bush bearing, laggy pieces of junk.

cheap = bad.

Thats one good reply...thanks R31Nismoid......

It clears my confuse now on the turbos....

u guys are the best in all this

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?

[R31Nismoid]

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.

I agree with Ash.

Don't skimp out becasue you want to save 500 bucks. Spend what is needed and get a much much better result. It will make for a far more enjoyable car to drive!

[gtr fan]

It’s also power delivery in/out of gears as well.

Absolutley agree with that point as thats why I swapped my -5's for -9's.

[pistol-pete]

dont try and skimp on these tings. the words 'cheap' and 'gtr' dont appear on the same sentence, in time youll learn this

fast,cheap,reliable.................... pick two

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

[R31Nismoid]

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

[R31Nismoid]

also exhaust is a bit small.

a 3076 would've been a better choice for your current mod levels.

[AussieR31]

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.

[R31Nismoid]

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.

[AussieR31]

Cheers, thanks for you support. I am building for power & speed, lag isn't too much of an issue, I was expecting some, but sounds like a little more than I expected. Will see how it goes, might be ready for dr. drift dyno day.

[AussieR31]

Oh yeah, getting it tuned to about 300rwkw also, good stab

[krzysiu]

My mate with a r31 rb30et with a 3582 pulled 265rwkw with a bit of lag. But kept up at my rear quarter panel with my rb25 with a 3076 at 281kw. All in the weight haha

Let us know your results

[AussieR31]

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.
