I emailed these people a while back about this.

I was told that after hi flowing they can do about 270rwkw.

They also said they can do the GT3071R CHRA into our housings for $1750 including machining and oil feed/drain lines which i believe is a whole lot cheaper than GCG.

they quote 450hp using their ART28 with a G3 profile using the standard compressor and turbine housing. They also said that it would be unlikely to see much more HP using the gt3071r CHRA but rather a slight increase in response.

Well so long as it's more responsive than the factory turbo, and more power handling with the GT3071r, that's great.

the CT15 housings are to restrictive to fit the GT30 internals to.

Theres an CAD drawing on here somewhree of an adaptor plate to bolt a GT30 straight to the factory manifold etc, which will be a much more efficient and larger gains

nice. one thing tho. the plasma cutter doesnt like holes smaller than 11mm on 10mm plate. and i can do tons of these in mild steel or wear plate.

is this to bolt up to factory 1jz manifolds? cause i'm not seeing the 3 bolt pattern. what does a ct15b usually reside in? vvti?

Which housing, the turbine or compressor housing? The turbine housing is machine to fit the gt30 internals. I'm not sure if they can machine to a specific A/R ratio though. eg ask for a .86ar or a 1.06ar.

I think even if we used the adapter plate with the gt30 turbine housing, you would have to modify the dump/exhaust to fit. If you were to also use the gt30 compressor housing you would have to modify the intake and intercooler piping to it. The costs start to add up!

This is a really really cheap alternative to the stock turbo which in itself it capable of 200rwkw. So i guess providing your not looking for 300rwkw this is quite a viable option

Jacob , Have a read of the VVTi specific section regarding your questions as its all answered in there.

I would be going for an adapter plate option and a T3 style garret if it were me and not stuffing around with an existing turbo.
Just sell the stocko for a couple of hundred bucks and use that money towards your NEW turbo!

So just the exhaust housing is bored out and exhaust wheel replaced, compressor left alone?

The comp will be replaced aswell,

Most high-flow turbos are prone to compressor surge, So its somthing to watch out for, A lot of guys have dramas with Staos High flows not holding boost, and he has some nasty ugly ways of getting around it.

I have a hypergear turbo but no a highflow.

If I were to do it i would buy a GT3076 without the turbine housing and get stao to fit the CT15 turbine housing to it, wont be anywhere as good as a true Gt3076 but will be ok for anound 250-260rwkws where as a proper gt3076 can make upwards of 350, and do it will less stress on the engine, than a bastarised highflow.

I think there's a mix up. Hypergear dont highflow the CT15 turbo. They replace the whole CHRA (core) with a gt3071 or atr28 and just machine our housings to fit.

Still classed as highflowing, just not a direct bolt on one like GCG or MTQ can do.

the rear housings and front compressor housing will cause a restriction, there just to small a housing for the GT30 cartridges, look at a standard GT30 front housing then compare it to the CT15 housing and rear housing.

Hypergear not a direct bolt on? As in you cant put the turbo back on? why not

While It will bolt on to the manifold flange, All the oil and water lines will need to be custom, As we have said much easier to go straight to a proper GT3076 (with the 6 blade comp wheel) and port shrouded comp cover, Dont bother with the 3071, the minute gain in response you will get will be offset by comp surge and it will fall 40-50kws short.

While im not a fan of adaptor plates, It would be the easiest option, just not the most effective, Best option would be a 3076 with ATP's twin scroll T4 .82a/r turbine housing on a twin scroll/twin gate manifold (6-Boost, ETM, or Full Race)

Would make full boost at around 3000revs and make upwards of 500rwhp (375rwkws)
But a setup like that is big bucks, but well worth it if you want the ultimate setup.

any way ive rambled on enough lol

i'd have to agree with you andrew, but i'm thinking this hypergear alternative is a cheap effective option to replacing a busted/old ct15b with something thats going to give you reliable power in the 200kw range without requiring excessive mods the 3076r would.

Personally i'm not after a dyno queen or something with 375kw. I want a city driver with something around the 200-220kw thats reliable day in day out and i dont have to rev the guts off it to be in the powerband.

Ok cool, that makes it simple, go for the atr28 high flow, the atr43 will be overkill for 220rwkws (and the standard housings)

I have a ct15B. Judging by the markings, my rear housing is .86 or was it .82 lol.

I honestly wouldnt bother with Hypergear
