Here are few more Photos of Powered Up high flowed R33 turbo with 2IU turbine housing:

Note the difference in volume of modifed turbine housing on the right:

Thats some cool modifications and porting to the housing.

Hi

Whats the response difference or lag difference between the G2 and the GT3040?

I have a R34 GTT Auto, a brought a GT3040(GT3082) with a .82 rear housing a while ago to put on. Now i think it might lag to much with the auto.

Am thinking of selling, to get the ATR43 G2 or get the original Skyline turbo high flowed.

PS. Only just found this forum topic and have just joined SAU

Hi there. If you are looks to make around 230rwkws with excellent street driving ability I can high flow your stock turbo to same spec as a 2530.

On GT3040, boost wouldnt come on at all under 3500 (which when driving normally is annoying) with G2 turbo comes on about 2700 (only couple of pounds which count when your trying to over take). Full boost 3500 rpm.

LAG:

On gt3040 i would have full boost at around 4500

G2 1st gear 4000, 2nd gear 3500, 3rd gear 3400 5th 3200 rpm.

My opinion:

I was supposed to go for G2 from the start, and mates talked me into getting 3040 instead (M I S T A K E). Unwanted attention, got put off the road. canary.

G2 is better or as good up to 5000RPM, after that not as good but very close to GT3040 IMO. Fully legal, i recommend G2.

do you guys do replacment for standard turbos on a r33 gtr? what specs are they and how much power would the rebuilt turbos make? also how much would they cost? sorry couldnt find anythin reading through the pages only found rb25 upgrades nothing for the rb26.

Hi

Thanks for the info. I will look at selling the GT3082

With RB26 we normally high flow them to 2860RS spec. which works out to be the -9 configurations in your stock turbine and comp housings. they would be ok for up to 320rwkws before you need bigger turbine housings. Response wise they feels like the N1 steel wheel turbos. Not as responsive as the stock cermaic wheels.

We can build custom .60 A/R comp and .64 / .86 turbine with OEM boltup pattern for those if required.

ATR43G2 .63 with high pressure actautor and braided oil feeding line we can do for $1530.

To high flow your stock R34 turbo cost $960 including braided oil feeding line. high pressure actautor is additional at $150 each.

I'm curious as to whether you have done one of these custom turbo's for a GTR yet and if so any dyno graphs or similar or info

Have done few. Not as many as other turbos thou. Have also driven one. Un-tuned, car pulled hard after 4500RPM but have lost fairbit of response to stock ceramic turbos. its about 300RPM laggier then stock N1 turbos.

how are the variable turbo's coming along?

something i found on youtube to give people an idea...

Sounds very interesting, what is the price on this for an R34 OP6 turbo?

how turbo works for beginners like me lol

Convert that into OP6 R34 turbo cost $1000 including braided oil feeding line and oil drain adaptor.

To do this we have to modify T28 bearing housing to suit a T3x pring turbine housing.

I was thinking if you could use the new VARA turbo's that your making in a GTR...maybe not

Probably not at this stage. They are too small to work with.

Hi guys just want to know roughly a price of highflowing a rb25 turbo thanks..

[hypergear]

Standard from $800 + GST + oil line $80 = $960

Powered up high flow from $1100 + Oil line $80 + $150 High pressure actautor = $1310

This might be a silly question but is it possible to just replace the standard ceramic turbo wheel with a steel turbo wheel so that boost can be raised safely above 12psi? Do you offer a price for that? Would it still require a different oil line?

[hypergear]

We actually build a brand new turbo core with bigger wheels, then machine your stock housings to suit it. We only use steel turbine wheels. So are you actually getting back a brand new turbo inside your factory housings.
