The other cool thing is the response, its dead smooth and can easily be manipulated through some turns without that big turbo SMACK. I am usually not impressed by anything Subaru anymore, this stuff was AMAZING. On e85 this setup would KILL, I cant wait to see the GR kit that doesn't have the room restrictions."


Just for a comparison to a regular rotated gtx35, mine hits 20psi by 4500rpm.....so thats a solid 700rpm faster spool. Thats pretty damn impressive.
The gains are in the spool are from lack of heat loss, "short runner" manifolds are great for spool. I wish I could share some ideas I have, pm me if you wana to hear some "theories" .

Oh yah, big ups to kb and jrtuned for a very sick powerband/build.

Agreed this a damn reasonable price for a 321SS header, Ron Davis radiator and the FMIC with all attendant accoutrement. No reason to go smaller than GT35 either.

Anyone going race gas or E85 + head work and cams will see an easy 600whp. Easy.

Looks like the new standard. Congrats.

The GTX3576 is actually a GTX30 compressor with a 35R exhaust wheel. Put a 35R size compressor wheel in there and it will really shine.

That's not a bad idea...

A GTX3576 is actually a 76mm compressor with the 35R turbine wheel There is nothing specific about the 76mm compressor wheel that says it has to be on a GT30 size turbine. Someone could make a GTX3776 if they wanted to, or a GTX2876. Not saying those would be good ideas, but it could be done.

As per Garretts website, the gtx 3576 has a 76mm compressor wheel and a 68mm exducer on the turbine, which is what the Gt35xx turbos have. So Kelly is right.

The gtx30 turbos have a 60mm turbine exducer.

Thanks for the kid words! The radiator is not a Ron Davis, it is a Killer B design

The larger compressor will not fit as-is. It would go from a true "bolt-on" to "some hammering and cutting required". The OEM lower radiator support would need to be tweaks as would the side support. The metal is all thin in those areas. I would estimate a max of 10 whacks with a BFH would do the trick and quick trim with a set of tin snips.

We've been telling folks on here about the great characteristics of these headers, even in the stock location or rotated stock location. People seem to want to doubt or debate this based on prior older designs and theories but results speak to their efficiency. They do change the VE of our motors in a very positive way and I'm sure Junior can elaborate on this if he likes based on the tuning he's done with them.

I (or any other owners) and Junior can tell you they are amazing headers because of what they can flow and how quickly they flow and the great heat retention of the 321 tubing! The spool up with them is very very good, I've run them with a VF48 37lb/ min and now the Dom 3.5 58 lb/ min turbos and they both spooled very quickly with this header.

This kit even further improves on the efficiency by further shortening the pre turbo exhaust tract as well as the post turbo charge path.

Killer (haha) job here Chris and great tuning Junior!

Damn though...I may have to put this kit on my XTI, I do like how my car is running now but this would be even better!

My car would be a good test bed for these Chris!!

I'll bet a little bit of work with a BFH, a nibbler and maybe some reinforcement/ gusset type welding would make short work of this fitment.

Beta please

I would buy a 04-07 car just to beta test this stuff for you. 93 results, e85 results... ESPECIALLY TRACK RESULTS

As for being able to put a bigger turbo on the setup. This setup with a 6466 would be the ULTIMATE kit. From my Experience the 6466 and GTX35r spool very similar, the 64 being about 200rpm lazier. Only real issue would be the fact that the PTE is a little longer compared to the Garret cartridges. Being that Chris made this kit to be 10000% clean and cutting free, a little trimming I dont see the bigger PTE stuff being a problem to install.

GT30 = 60mm turbine wheel. GT35 = 68mm turbine wheel. The frame sizes refer to the turbine side only. That's it.

You could make a GT3571 if you wanted, or a GT3082 (which actually was made back in the day).

76mm compressor does not automatically mean GT30 as Kelly implied.

The true beauty of this kit is this.. Your average enthusiast can install as a 'simple' bolt on and have a large turbo like the GTX3576R fit like a glove(and that power band is just pure awesome - but it's begging for E85 and a 8.5k redline ).
While your can't-let-well-enough-alone tinkerer will, with little effort, make an even larger turbo work.

I still think(especially after seeing your results) I'll stick with the X3576 once you release the kit but the 82 is tempting.

I can attest to that!
I bought a GT52 used a year or so ago for pretty cheap to replace my 16G. When I told my tuner(Mikey) he expressed his disappointment with the turbo as it performed poorly on a previous car he tuned(slow spool and fell of too quickly).
Well he and I were both extremely impressed with it's VF39 like spool and solid top end.
I'd say the money spent on KillerB headers was well worth it.

Now to impatiently wait for the low mount kit to be released...

What kind of crazy person would do this!?! Muahahaha!

Our latest Killer B play thing; Round to Divided (Twin Scroll) T3 with a Divided Wastegate made from Cast 321 Stainless Steel... I suppose I need to think of a name for this thing too?







Special thanks to Garrett for coming out with an awesome new performance oriented TS Turbine Housing. Looking forward to testing this out!

WANT!!!!

Will you have to weld right to the cast I take it? Looks amazing, the single gate is going to catch grief by some but I imagine right there the losses are so minimal it wont matter. I'm sure garrett did their home work.

Can you show a pic of how the EWG transitions to the runners? Is there a divider plate all the way up to the EWG seat?

There is no plate per-se, it's all part of the casting, but yes it goes right to the gate's valve

They messed up by not putting vbands on there. Hopefully it is an option at time of purchase, I understand a lot of custom work will be done initially so it won't be a huge deal to weld one on

Yea but which one? Tial 38? Tial 44? Another manufacturer? Better to leave it off.

It's cast so building in the vband flange would necessitate machining and cost for KB as well as lock you into a certain gate. At least that's how I see it.

V-bands where, WG? The housing adapter requires welding anyway, to the secondaries.

Putting them ON the casting would make the casting tooling significantly more complicated/expensive, would require a secondary process (machining), and you'd be throwing away the WG flange that is already included with the WG.
