Mitcho_7 Posted June 29, 2012 Share Posted June 29, 2012 (edited) 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 Edited June 29, 2012 by Mitcho_7 Link to comment https://www.sau.com.au/forums/topic/403526-rb25-gt3076r-turbine-housing-size/page/3/#findComment-6422251 Share on other sites More sharing options...

OoskylineoO Posted June 29, 2012 Share Posted June 29, 2012 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 Link to comment https://www.sau.com.au/forums/topic/403526-rb25-gt3076r-turbine-housing-size/page/3/#findComment-6422468 Share on other sites More sharing options...
GTScotT Posted June 29, 2012 Share Posted June 29, 2012 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............................... http://www.atpturbo.com/mm5/merchant.mvc?Screen=PROD&Store_Code=tp&Product_Code=ATP-HSG-037&Category_Code=GTH Same genuine item, with a realistic cost (still a lot of money but its swallowable).

OoskylineoO Posted June 29, 2012 Share Posted June 29, 2012 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 Link to comment https://www.sau.com.au/forums/topic/403526-rb25-gt3076r-turbine-housing-size/page/3/#findComment-6422866 Share on other sites More sharing options...

Jap_star Posted June 29, 2012 Share Posted June 29, 2012 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 Link to comment https://www.sau.com.au/forums/topic/403526-rb25-gt3076r-turbine-housing-size/page/3/#findComment-6422873 Share on other sites More sharing options...

Jap_star Posted June 30, 2012 Share Posted June 30, 2012 Which do you prefer? Do you have a build thread etc? Interesting to hear the differences between the housings yeah id like to know what was preferred most also 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 Josh Link to comment https://www.sau.com.au/forums/topic/403526-rb25-gt3076r-turbine-housing-size/page/3/#findComment-6423502 Share on other sites More sharing options...

AngryRB Posted June 30, 2012 Share Posted June 30, 2012 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?

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 Posted June 30, 2012 Share Posted June 30, 2012 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, Link to comment https://www.sau.com.au/forums/topic/403526-rb25-gt3076r-turbine-housing-size/page/3/#findComment-6424018 Share on other sites More sharing options...
