EVO 11.5 Hotside, anybody try it?
Id say some of the greatest evidence on here against the 11.5 hotside was what 211ratsbud stated about the metallurgy of it when he was cutting it. That's a big difference between the two if it cut that much easier. Id gladly take whatever small percentage of gains is had from 11.5 to have a 10.5 that will actually hold up.
FWIW, I thought I saw a website from a shop out in Australia that supposedly uses 11.5 hotsides. I don't know if they are using the same Chinese knockoffs or if there's is somehow better.

The housing is no different. Bought one, blew turbo, cut the housing up and comparee to my oem housing the only discernable difference was in cutting the pieces. The 11.5 cut like butter and the OEM ate my blade. a 14 tpi band saw blade. FP has noted that had a high quality aftermarket housing exist, they woud use it.
Its a clone of another mits part with AN3 stamped on it to make the spec nerds go crazy.
Im sorry but I had hoped this thread was dead for good: Lets look at the cost this thing incurred me:
Bought housing to be installed by FP when my FP white rabbit was toast. 200$ +....
Rebuilt turbo not fault of housing fault of abuse
recieve turbo and install. primed and warmed up the turbo takes a dump.
FP gets turbo says housing was incorrectly made
rebuild turbo 400 +
buy OEM housing because original was junk, and kinugawa was junk 325 +
back to square one. Turbo has been running for 2ish years since then.
cliff notes. FP knows a thinkg or two about turbos.
when it oxidized in my garage there was even a good amount of difference in the rust color in comparision

Where were you able to find an oem 10.5 hotside? It seems like lately, a new, Genuine Mitsu hotside, is hard to find without buying the whole turbo. Well, apart from buying from Mitsu. I remember a few years ago, Buschur,FP, would all sell these for reasonably priced. Not anymore. Whats the deal with this shortage of hotsides

I don't think MHI sells the hotside alone any more, and the divider between the volutes tends to crack after a while where it ends at the turbine wheel.
FP has finally decided to make their own hotside now, but for whatever reason, they decided to go with an EWG design. I hope they can come up with an IWG hotside that will be less expensive because I can only imagine that their EWG hotside + EWG is going to add another $800 to the price of their stock frame turbos. Hard to rationalize buying a stock frame turbo at that point.

That may be one advantage someone will go for a stock framed setup vs T3, well, at least in California that is.

Stock framed turbos will always have a visual advantage for smog inspections out here in California. T3 setups, EWG, and tubular manifolds throw a red flag. Some of these smog guys are fanatical to try and fail you. The last smog guy was giving me hell about my ETS intercooler pipes asking for a carb sticker. I showed him how I still had the stock intake, but he wasn't believing me. I would hate to try and pass visual on a T3 setup.

Yeak huh I'm not trying to be youdisrespectful and if you're happy with that turbo then more power to you, or possibly less power to you? Lol jk. To each their own and again I'm glad it has worked out for you. Personally I just wouldn't want to put a $900 turbo on a $35k-$40k car. It's like putting a pig on perfume, ya backwards on purpose.
I'd hate to get in a pissing match with someone like you.
With your pretzle logic...so I need to spend what 1500-2000 and then its all good? So keep the $400 stock turbo?
How stupid...if it works then great if not oh well...but just to sit there and judge because its not the correct name. Well that's just close minded. As far as pigs and perfume I'm thinking you may need more purfume then my turbo...you have zero manners and what makes you such a great athourity?
I'm gussing nothing....so enjoy your set-up and ill enjoy mine...
LOL..JK*

No one is ragging on you personally(At least not I). If you are running the stock TD05H turbine wheel, then that 11.5 housing should be fine. The problem FP encountered was only when they machined the housing for their proprietary, larger than stock diameter turbine wheels.
Ramses, runs an 11.5 with great success on a stock IX turbo coupled with an FP flow-advancement compressor housing. The 11.5 has advantages including lower back pressure, higher peak power potential and an apparently improved bypass port design with a larger diameter flapper valve.
As others have stated even the stock MHI 10.5 housings are prone to failure. Mostly in the divider wall area. But, this is an inherently weak area in most divided, or twin scroll housings regardless of manufacture.

Just to what 11.5 cm2 is specifying, the product on ebay saying it is 10.5 ported.. So no diffecence except the nozzle area inside the housing (narrowest area between turbine wheel and -end- of the scroll) and of course the material/form copy..
I believe it can be ported thus enlarging this "circular flow dump" area, but the design is still 10.5.
Nice explanation (that helped me to finally understand difference between 10.5 and 9.8 etc.) you can find from SaabTuner here:

still have it
all kinagawa set up
this was all I could afford.
and maybe im lucky
2 yrs later it run great and I am happy.
If I was single w no kids maybe I be always looking for more power.
but ive never just bought for a name.
this system works great. It dosent matter if you agree...im just letting you all know it is possible to have your cake and eat it too.
spent the savings on a vacation w my family......
I read the entire thread. Definitely interesting. In the end I have been looking for an Evo IX turbo and all that I have come across are either a million miles old or look like they should be. The good ones have already been scooped up.
That left me with being able to buy a OEM Evo IX turbo minus the turbine housing. After reading--- I just cannot bring myself to do it, so I spent a bit more and bought a new stock turbo. I know I had other choices, but for me this made the most sense.
