3071 Rear Housing

[Greekos]

i have a 3071 turbo that had been sitting in my garage. i sent it to gcg to get a rear housing put on as the current one developed a slight crack. the problem is that i'v been given a quote for close to 1300, does this sound normal or am i being overcharged because i can buy a new turbo for not much more.

you can grab a new rear housing, .73 size, from AVO turbo world, for $700

thats what is on the rear of my 3076

yeah i would go that housing also. you can even fit it yourself, just be careful not to damage the turbine wheel when removing and refitting the housing and it will be sweet.

did you manage to get any power out of yours

I ended up pulling mine off and going to the .82 external gate because it didnt want to make power for me

Mine also had hairline cracks around the wastegate hole but GCG told me that's normal

its just sitting here in the carport so if you wanna buy one down the track let me know

my 3071R with AVO style .73 housing made 280 rwkw on 16psi with cams, 280 on 20psi with stock cams,.

heya

ATS adelaide turbo services suggest the combo should be good for 280rwkw give or take

that'd be on a manual rwd rb25det : auto awd would lose 20kw

with auto, mine is flowing 240rwkw nice and clean, with heaps more power in it - 260wkw auto awd is the goal

fixed the issue of my fuel cut to an extent - 6500rpm is now the gear change point aka limiter; unfortunately that leaves the 3076 in the meat of its power delivery

on the dyno at 6500 the graph-curve shows it'd hit 250rwkw at 7000rpm

but then again, auto full boost quick-changing at 6500rpm right in the meat of power delivery isnt that bad. also depends on boost level/settings

got a power run on sunday 8th dec on a all-wheel drive dyno, so will see how it goes on full boost

will update the auto performance thread accordingly.

thanks guys is there any way they would have a .83 rear housing as i was have trouble controlling boost at my power level.

what housing was on it before? is it a proper 3071 or a "bolt on" 3071? they're different and cant be interchanged

[bradsm87]

That's heaps. It's easy to change yourself. Call morrie from horsepowerinabox an ask him wat his best price on that housing is. I reckon $500 max.

[hypergear]

If you can send in the CHRA we can profile a .82 internally gated rear housing to suit it that bolt on to your stock manifold and dump for $500. This housing is capable of holding 22psi of boost on internal gate.

[JonnoHR31]

if he already has a proper garrett housing and dump to suit that'd be a step backwards. but it all depends on what he has
