Gtt Stock Turbo At 13-14psi All Day

[R31Nismoid]

2000 is solid value when you look at the results (Which are all over this forum, searching GCG etc)

Dont the R34 turbos have nylon turbine wheels hence can only run 10psi max?

Thanks

It's not about the compressor wheel. The exhaust wheel goes.

Also my cat was not damaged at all and although I did drive home it was blowing a truckload of smoke so I guess some seals got broken when the wheel let go.

The R33 turbos have the same ceramic exhaust wheel as the R34 ones.

From what I read the R34 turbine housing is slightly larger than the R33 one. Do you think this helps the R34 turbo to shit itself easier due to more hot exhaust gases. Or do you think the bigger exhaust housing is irrelevant.

Would fitting a VG30DET exhaust housing to an R33 turbo be a good little upgrade? I believe this housing is the same as the 34 housing?

I guess its not really a good upgrade if you have to pull your turbo off to do it.

Whatwould you expect - 10-15kw gain from the bigger housing?

it would be very skeptical of any model of the turbos really dying faster than the other.

as stated, the 10psi rule is across the board.

man am i the only r34 whos compressor wheel crapped itself?

[Bass Junky]

Yes, you can fit the R34/VG30DET turbine housing to the R33 Turbo, but you wont really pick up that much.

You have run out of compressor flow well before changing the exhaust housing will have any effect.

However, should you change to the R34/VG30DET housing AND get it all high flowed, then you can pick up some serious gains.

Do a search on "Hybrid Turbo" and you'll find that a guy fitted the VG30DET housing to his R33 turbo which has been high flowed and he picked up masses of power. 25 kw top end and about 50k through the guts.

Mine came over like this

i throught it was stock but it pushes way to much kws

iv heard 800 up to get them hi flowed

wen they go in japan some times they will do this and this only

save any more problems in the future but does not make a massive difference in power i can just run high boost

[benl1981]

Miller..so yoiu think yours has just got standard ize wheels but just in steel?

If that was able to dish out about 210rwkw reliably I reckon that would be the go for me.

Have to call GCG to see how much it is. 10 psi seems to be the max for the standard turbo and 8psi on the track. Even then it could shit itself it sounds like.

With steel wheels you could probably run 12-13 psi. ANymore than that I guess you would get hot air.

one more question.

does the turbo generally blow from the hot exhaust gases or from spinning to fast? or both?

[Miller the hoon]

I have turbo back exhaust + hi flow cat

front mount with plumb bac and pod

e boost 2

i run mine on 9.7 to 10 psi max

i have an auto and on 8 i pushed 245rwhp easy

when i get fuel system, shift kit and greddy e manage with ignision harnes i recon i will get at least that

before i got a boost gauge (eboost) i would run mine soo high i would get computer cut out but i never had any turbo problems so

no 1 has looked at it out of the car yet

if it would not cost me i would let people see it

spools soo quik i mean i can do a power burn out with no brakes some times

heat

[Busky2k]

Pretty much all of them. Spin it too fast, heat it up... goes hand in hand. To be safe, I'd run it on the rich side to keep the EGTs down if you like to thrash ur car a bit..

I ran my r33 stock turbo on 15psi for 2 years without any trouble. Wasnt a standard ecu.

The turbo is still in good condition in my wardrobe.

I dont think it would have survived a track day though.

[cerci]

really? 15psi??

dosnt it feel it just had no more 2 give at that psi?

i guess different specs for different peoples cars and setups

[Zombie]

Yeah it was probably out of its efficiency, but i have a bigger one now and run 18

[noise]

I turned down the boost to about .7 bar/ 10psi and now the car feels slow

oh well at least the turbo wont blow

I will probably still pop it back up to 1 bar when I go cruising on a cool night.
