Is the Buschur 20G-9-5 the same as the 50R? I assume that is what the "5" refers to.
And is it that much different than the stock IX turbo - I pretty much presumed the 20g-9 would net about 30whp over the stock IX. So the 20g-9-5 much be vastly different.

This improved version has recorded trap speeds about 4 mph higher than the original 20G-9-5. He claims that it reaches 20# by about 3500 RPM. It sounds mighty promising and is probably the way I'll go if I decide to upgrade my TiAl RS turbo.
Edit: FYI, this latest version is not yet finalized and is currently undergoing last minute tweaks and testing. There are no production units yet so we don't know the specifics of how it differs from the current BR 20G. Obviously no dyno numbers yet either. But the increased trap speeds do give an indication of its power giving potential.

Maybe a 50trim is a better option. The ATP 3076R kit I've been talking about is $1800. Stock manifold. Just the turbo, E/WG, exh piping, etc. Basically bolt on stuff. I thought it would be a somewhat cheap upgrade.
Better you do a thorough search on the ATP 3076 kit. If I'm not mistaken, that particular setup is not quite cutting edge and the performance leaves a lot to be desired. I agree that $1800 seems cheap, but......don't go and throw away your hard earned clams.
Man, those are impressive torque #'s with that IX turbo on 100 octane! I gather that you'd like those torque numbers on 93 for your DD chores and a bit more for the track. Probably, as others have stated, the fastest spooling 400 WHP/400 WTQ pump gas kit is going to be an AMS or TT 50-Trim. Then there is the 3076/3037 Vishnu kit. There are still some Apexi-IHI kits out there which wouldn't be bad for road racing either.
These high quality kits are mostly $4000+. Sure, they are ultimately superior for road racing than a bolt on turbo but they'll cost about double and you'll need to go to bigger injectors. If you want street torque and good spool and 400+potential when you go to the track, then the 50-Trims are hard to beat. The 3076/3037 and the IHI are good choices as well. It just gets down to how much you're willing to spend.

Yea ... Im running a gt 3076r and the snail is good on the street ...good mid range torque and high end boost. If its for road race I would definitely stay in the 30 series turbo range....great response and boost starts building WOT at around 3200..until full boost at around 4k-4200...great great turbo....

OK, my take....
I just bought the 3076 instead of the 3071 and 50 trim.
50 trim (many many many diff configs/housings) basic upgrade from the stock turbo. Moderate gains on pump gas. Nothing earth shattering. (NOMEX underwear on!) Little noticeable lag over stock turbo. Falls off up top.
3071 next step up over 50 trim. Pump gas monster. About as big as you want to go on the stock bottom end with pump gas. Rod bolts would be wise. Little noticeable lag over stock turbo. Falls off up top.
3076 not worth it on 91 questionable on 93. Definitely not an autocross pump gas turbo. It is like a 3071 with top end. Pump + meth or race gas will make this turbo come alive. For 100% pump only, get a 3071. 3076 has Noticeable lag over stock turbo, not like a GT35 lag, but more like 4K spool vs 3.5K. Does not fall off up top.
I run meth so I went Vishnu V500 stage 2 3076 (3037 - same turbo). Pump gas get a 3071. Plus their kit comes with all the needed bits.
No I didn't make all this up. No I don't have a shop where I tested all this out. I have talked to several people that have the different kits from AMS/Vishnu/others.. and I have read on here a LOT! I am not an expert or a retard, I am somewhere in the middle and I don't have money to waste. So, I am kind of a well informed consumer.
Good luck with you decision.

Lot's of good info. Essentially, everyone seems to have a slightly different take on the 3076. Some say its old news - and the 50 trim is hot. Others saying the soon to be released 9g-5 Buschur is whats happening.
Also read up on the 6-blade conspiracy v. 5 blade. Everyone's got an opinion there, too.
In the end - it came down to price over performance. Can my IX get to 400wtq and be a DD? Yes - i think so. The dyno's I've found shown the GT3076R to hit full song before 4K - which, when you think about it, is typically where I am at on the road course. If I miss shift or leave the brakes on longer than I should, I could fall out of the power. But it probably wont be that likely. All 7K upshifts kick down above 4K in the next gear.
I talked the guy down to $1,550 - for the complete set up. Brand new in the wrapper. It came with Garrett GT Ball Bearing turbo w/ATP Proprietary Housing with GT inspired High-Flowing Valute, Tial 38mm External Wastegate, stainless wastegate discharge tube with downpipe re-route, all mounting hardware, gaskets and CNC machined fittings. Even comes with an inline MSD fuel pump. Which I may ditch for an in-tank.
For the money - it seemed like the cheapest option p/hp gain out there.
I'll post some pics and comparison to my current dyno #'s at the same boost level.

Here are my currently supported numbers. I've overlayed the 93oct curve with the 100oct curve. The boost was 21 for 93, and 26 for 100.
No power up top and spool up is terrible.

The turbine housing on the ATP is a known problem (considering what the turbo could really put out). You can do a search. Vishnu was going to carry the ATP kitsuntil testing proved they weren't living up to expectations.
IIMO, the best (stock looking) GT3076R kit out there right now is the RRE kit. I like it better than the Vishnu kit because the wastegate is easier to get to and it has it's own cast manifold, thus not requiring an adaptor plate.

Price is 3195 and same for every ~GT35R kit.

I ran a old style gt30 from BR with a .48 hot side and it spooled pretty well and trapped 123mph on pump, alky, and 26psi. I think it would have gone 11.30's no problem but I did not want to push and get banned from the strip.
The new BR kits are really nice for the money.
