Which Turbos Should I Get For My Standard R33 Gtr?

[Piggaz]

Gcg.com.au....$1070 a set of 5's, -SAU discount of 10%..

[Piggaz]

Shit. I mean per turbo!!! $1070 per turbo. Can't edit from I phone.

[Piggaz]

Grant. As good of a result that people have good power with stock dumps...there would have to be more to be made with a larger... Ie tomei, midori dump pipe.

How do I get the sau discount?

Best street combination for stock motor IMHO, much better than -7s.

Bollocks A *little* better than -7s when you're over 300kws otherwise SFA difference.

I'm 305kw @17psi with -7s.

OP;

- turbos are key part of the equation, no sense in getting -5s just because they're cheaper. You get them if you want 380kws. For 300 they're a bad choice.

- if you're ever going to do dumps, do them now, but you could just as well not bother. If you look at cost/benefit, -7s without dumps will be much better than -5s with dumps for around the same cost.

- when i checked pricing, -7s were $400 cheaper for the pair than -9s with new actuators. Dont use old actuators....

- you're thinking about cams (waste) but maybe buying -5s to save a little money? That doesn't make sense. You need to let us know how tight the money is and what results you want.

Option 1 - 280kw - cheap; -7s, cam gears, stock dumps, injectors, AFMs

Option 2 - 330kw - medium; -9s, cam gears, 550 injectors, nismo AFMs

Option 3 - 380kw - exxy; -5s, cam gears, 700 injectors, nismo AFMs, dumps, oh and BUILT MOTOR and gearbox upgrade to keep 3rd gear in one piece....

And Nismoid's exhaust rule;

300kw = 3 in

350kw = 3.5 in

400kw = 4 in

True, but kinda pointless if you only want 300rwkw or so, which I've done with success before.

But next time I may go for a pair of a/m dumps and see if it make any difference.

To much MrStabby thats uesfull stuff

Lets say your running 300kw on -9s and the engine goes after a year,then a rebuild is taken place, forged bottom end.and you wanna run 400kw that means you gotta buy -5s and sell of your -9 in away your loseing money ?so is it better of to get -5s striaght away?

[R33GTRNZ]

Money is a bit tight but I could possibly go with option 2 if I can find a good deal on some -9s.

Would Z32 AFMs be alright instead of Nismo AFMs?

[paulr33]

its basically the same thing

the nismo is z32 hotwire inside 65mm shell

the z32 is 80mm z32 airflow meter

so more or less the same

but in a twin setup the twin nismos will give you more resolution in low load area as the snout is smaller

I'd buy -9s and enjoy while it's there.

Buy -5s when the motor is out, people still will buy -9s even if used.

Pretty sure Ash will say the same.

Hey R33GTRNZ i think we;re on the same boat im from NZ to,im after a pair of -9s,was looking at some 2nd hand N1 turbos might be the cheaper option,i do wanna run 400kw but not with the stock motor and also dont wanna rebuild a perfect running engine

[Count Grantleyish]

Make sure the ID tags are 707160 -7.

[R33GTRNZ]

I'm from Auckland. I've heard that the rebuild costs for those turbos is almost 90% of the price of new -7's (N1 R34 equivalent)

[nitestage32]

Depends on what you want and stuff mate.

Nothing wrong with running -9s on a built motor. It'll make a solid 330rwkw, be responsive as all buggery and be an absolute street weapon. So if thats all you want then you'll not need to change turbos!

I've got 370rwkw now with -5s... I'd rather the response of -9s and 330-340rwkw. Admittedly I'm running less boost on the -5s than i could but response is king for a street car and makes it so much nicer to drive.

I don't dislike my -5 setup. However nothing really happens until 150km/h where the -9s were much more exciting between 60-150km/h

[waxracing]

n1 turbos on the r34 are ball bearing turbos and so are not worth while fixing.

forget them and buy new

[nitestage32]

i rang up redlineperformance today an quoted me $3061 for -5 and $3061for -9 both the same price.cheers for the help guys
