Rb25 Gt3076R Turbine Housing Size

[Mitcho_7]

Get it through street to track. He gets them from ATP turbo in the states an I reckon it would be half the price including postage to your door, compared to the gcg link.

The dollar is pretty decent at the moment as well

yeah GCG are taking the mickey if anything, dunno how they stay afloat with prices like that

[OoskylineoO]

wow expensive yes!, but then again that is a genuine Garrett housing and EVERYTHING else is aftermarket, they are apparently cast with different materials as well, some high nickel ni-resist material something or rather =S

[GTScotT]

More or less true yes, but its not worth 900.

Like someone said already itd be worth half that out of the states. Actually let me confirm that...............................

Same genuine item, with a realistic cost (still a lot of money but its swallowable).

I hope that helps.

So this will fit the GTX3076R as well?

[OoskylineoO]

different units, different part numbers GCG listing is the dearer version with upgraded wastegate valve.

Still doesn't matter, with the way the dollar is now why wouldn't u buy one overseas hahaha xD

On a different note, +1 on something wrong with set up hahah, blocked/restrictive cat perhaps? you can still make that same power with a 0.63a/r + more, will just run a bit hotter, don't necessarily need a 0.82a/r

They are interchangeable, only thing that changes in a GTX unit is compressor wheel and surge slotted comp cover

I had the .82 IW garret on mine, then the .63 external now the .82 external.

.82 was a bit laggy, full boost around 4200, .63 full boost by 3500, .82 external at 3800.

all different to drive

Which do you prefer? Do you have a build thread etc? Interesting to hear the differences between the housings

[GTScotT]

yeah id like to know what was preferred most also

I thought gt3076 had a port shrouded compressor inlet as well?

Maybe it was just a pic of the gtx advertised a the gt that I have seen...

You can have it with or without... Mine has the 4in inlet and surge slots, sounds mental too...

No build thread, sadly a bit too muchtime and effort these days. mostly just spam my Facebook with update pics

The .82 internal did its job, but the control of the internal gate is destroyed by external. From that experience if i was to put a large turbo on a car again, IW wouldnt even cross my mind.

the .63 was good, and to be honest it would probably still be on the car if it wasnt for an issue we thought i was having when i put the .63 in there. (turned out not to be the turbo) which was good but id had already bought the .82 to try and solve the issue.

the .82 external isnt very laggy imo, full boost in 4th is around the 3800 mark (19psi) and im pretty happy with that for what it is. overlaying the .63 and the .82 on the dyno the .63 is on about 300-400rpm earlier, but did make a little less in the top end, In saying that 2 mates have the same set up but with a .63 on their neo motor and didnt see the fall in the top end that my 33 did

End of the day car is a daily that sees a bit of track work, so for that effort the .82 is staying on.

the last 2 times we went to do a power run on 19psi turned out to be 40+ degree days. so we never got a proper run. since then ive had a low mount manifold made and installed, and tomorrow ill be going from 3" stainless steel to 4: titanium, so ill try and get some kind of power run in next week

Cheers for the info Josh

What pressure springs are you guys using in your wastegates, for the earliest response is it best to run as close to the pressure you want

for example, a tial44mm external and want to run say 20psi, what spring pressure would you want ( assuming you have an electronic boost controller)

pretty sure the one in mine is a 12psi spring, so wondering if it would get better response with a 16psi spring in there?

[Jap_star]

I ditched the ebc and run off the gate. I found it to work better.

I run 1 bar of spring, then use the mac valve to push boost pressure on to the top of the gate, helping hold it down. Works better with a 5 port mac valve like mine but the 3 port ones can be setup like that too. I can hold any boost now.

[AngryRB]

looking at my boost curve seems like the spring or the duty cycle was not done right, maybe resulting in a lazy boost curve etc.. looks like its heading for full boost at or before 4000rpm which is whats the norm round here but then take a further 500rpm or more to get from 15 to 18psi, so yeah i think the spring may need changed to a 1 bar spring and the controller adjusted for a more aggressive build up,
