My Turbo...a Good Thing Or A Bad Thing.

[GTR_Legend]

Guys,

After being excited about my new turbo purchase...i am quite disappointed.

Would appreciate any advise.

In short, This is what i purchased as advertised. (from a supplier who ordered from another supplier i believe)

Garrett GT3071R RB25DET T3 Bolt-on Turbocharger 500hp, Dual Ball Bearing Kit - 0.82a/r

Horsepower: 500hp

Compressor Housing A/R -: 0.60a/r

Compressor Inlet -: 4"

Turbine Housing A/R -: 0.82a/r

Turbine Hsg. Attachments: Inlet: Standard 4-bolt T3 flange

Turbine Hsg. Attachments: Outlet: Nissan 6-Bolt

Oil Inlet - : Inverted Flare 7/16-24 thread

Oil Drain - : Standard 2-bolt T3 flange

Bearing Type: Dual Ball Bearing

Cooling: Water Cooled Centre

Wastegate: Integrated Wastegate

Includes:

1x Garrett GT3071R RB25DET Turbocharger, complete High Nickel Content Cast Iron Nissan Style Turbine Housing with Internal Wastegate and actuator.

Fitting Kit Includes: Oil Drain, Oil Lines, Water Lines, Turbo Gaskets, Spacer, Studs, Nuts.

Turbo was delivered direct to my tuner, who had spent approx 9 hours labor to install, and needed to purchase the following.

4x studs - apparently the ones provided were not long enough or universal instead of metric.

10m spacer as it was not included.

An earls adaptor for the water or oil line i believe. (Lines were provided with the kit)

2x turbo hoses and clamps

also something about re-aligning the compressor housing??? i think. did mention he is surprised they were not using jigs

Picked up my car today after not having it for 8 days or so.

car is making 243kw@tw on 14psi

I looked at the new turbo, and can see the following.

compressor housing .50 A/R

garret ID tag: GT2835 - 700382-003

researching the above, it is the cropped version?

So all up, i have paid for a product i was not delivered with, and spent many extra $ to make it bolt on.

PS. my tuner was not aware of the turbo being delivered, he only knew one was turning up and needed to be installed.

Anyone else had an experience like this and what have you done about it? or, what would you do in this case?

Hopefully it isnt the cropped version.The results seem good for the boost being run. IMO there is no advantage having the 4" intake as opposed to the 2.75". Pretty much all the other bits needed are common knowledge for fitment. How much was it?

def think its cropped from what i read.

$2460

[wolverine]

It's in a Nissan housing so it is a fair guess that it has been cropped.

edit: that and the tag saying GT2835 which should be a 56mm turbine to start with.

[Adriano]

I assumed it has the AVO nissan "style" exhaust housing, hence the price

[_Ryan_]

if a 2835 is cropped, what makes the avo reared 3071 so bad?

[boostn0199]

I think for a 3071 IW your about right on the power , take it up to 18psi should see 270-280kw doesnt seem like anything wrong with it

[The Dan]

The GT3071 - 20 is the same as a HKS 2835

so you got the turbo you ordered. The power is good for that booet on that turbo IMO

What exactly are you not happy about?

[GTR_Legend]

thanks for the replies guys.

the numbers are confusing the hell out of me.

I am just concerned that i have not been provided with what i ordered/paid for.

so, my turbo is a .50 compressor, turbine 700382-003. and looking at the rear it has "sonic" written on it.

looking at the sonicperformance site, they state they have a .64 turbine housing.

and on the site from which i ordered it, the specs below differ.

Compressor Housing A/R -: 0.60a/r

Compressor Inlet -: 4"

Turbine Housing A/R -: 0.82a/r

Turbine Hsg. Attachments: Inlet: Standard 4-bolt T3 flange

Turbine Hsg. Attachments: Outlet: Nissan 6-Bolt

Oil Inlet - : Inverted Flare 7/16-24 thread

Oil Drain - : Standard 2-bolt T3 flange

Bearing Type: Dual Ball Bearing

Cooling: Water Cooled Centre

Wastegate: Integrated Wastegate

he is not happy about the following...

he added Red Bull to his skyline...cost...$3.50...result...supersonic multi million dollar jet fighter.

he then tried a different turbo...cost...$2460...result...243RWKW to remove the skin off his custard.

Id be pissed too!!

Moral to the story...drink Red Bull and dont eat custard!

[NYTSKY]

Only you know what you are talking about in that post Paul

[DRD-00F]

I thought you were off the sauce paul?

[TiTAN]

that stuff is a little stronger than sauce.

Gt3071 is basically the same as the hks spec Gt2835 so going by the id no. it seems to be right.

The rear however will be cropped to fit the Nissan style flange and its highly unlikely it would be a .82

The comp housing it supposed to be .50 a/r as well for the Gt3071, the Gt3076 however comes with the .60 a/r comp

That power looks good for 14psi tho....20psi should get u up to 270ish

They don't crop the turbine to fit the housing. They machine the housing to suit the turbo.

It will be all the same specs as the 3071-3 that the ID tag says. The turbine housing A/R is 0.73.

$2460 is spot on the money considering it didn't come with spacer, studs or silicon.

Who did you buy it from?

Keep in mind that the ID tag has nothing to do with housings. It only identifies the cartridge.

All the specs I said in the above posts are accurate. I sell these as a sonic dealer myself.

[Don Dada]

Ha ha.... thats what i meant

This .73 a/r is from using the OP6 back end?

If you're referring to the VG30 back end then no, it doesn't. They are a new casting

[GTR_Legend]

thanks again guys.

i am actually happy with the power and performance of the turbo...

below is the site

http://www.tweakit.net/shop/product_info.p...9ij7uter43vvdj6

didnt come with the silicone reducer etc... which i am fine with. but think it should at least state "misc parts may be required to fit"

spacer is listed, but wasnt supplied, cost me another $30 for part + delivery. then some labor to grind.

water line and oil line was supplied, but required an adapter for some reason, cost me an extra $30

studs were supplied, but didnt fit. cost me an extra $45

also required an elbow

and as mentioned, the tuner had to re-jig the alignment...or something like that.

so a few extra $ and hours in labor i had to fork out for.

would i be correct in saying that the site is incorrect? false advertisment

paul, just because you cant use e85 in your car doesn't mean you have to drink the rest of your stock
