Yes, you're right, the mag ones were blowing. Seems the USDM IX turbos should be a safe bet then. I suspect you guys got the inconel ones. I have been getting a lot of feedback that upgrading to a IX turbo is a waste of money and that I should shoot for a 20G instead but the idea of going 20G and needed to spend more money on injectors just doesn't make sense to me at this point in time.
I'm running my car mostly on the A1 circuit track near my place, and will probably be looking to autocross it, so the speed and smoothness of the turbo response is a priority over big power. Given this, my mind is still on the IX turbo and Megan coilovers (I saw in your other posts that you had glowing feedback on them -- not as good as the race setup you have now, but definitely better than stock)
I think a stock IX turbo with Megans will be a great, affordable route for you to take right now. Look at me, I'm planning to compete nationally this year in both SCCA Solo II (auto-x) and NASA TTS (road racing time trials), and my goal is to trophy in both. I'll be doing this with a stock IX turbo. A 20g (the right one, there are several versions) will make more power, but it will require injectors and will spool more slowly. Otherwise, it's still a direct bolt-on, which is great.
So Warr you got the coolant lines and the outlet pipe? And if the turbo is all you get, like in the ebay listing, does the Buschur 20g-9 installation kit have everything to make it plug and play?
Yes, I got everything it needs, because mine came right off a IX upgrading to a GT35R. I told him that I required the entire kit (oil/coolant lines, compressor outlet pipe, and wga), otherwise it was no deal. He didn't really know anything about it and didn't care, so he ensured the shop (AMS) sent me everything. It all showed up as one package still connected in one piece.
If you get a 20g-9 or 20g-LT from Buschur, then yes, you need to get the installation kit for your 03. The kit they sell has everything you need, but you can also get those same parts for much less through Mitsu. I don't have the part numbers, but I can get them.
Cool. I just wanted to know what to ask for if/when I find a IX turbo for a reasonable price. Also I was asking if the 20g-9 install kit would work for the IX turbo, but it's a moot point I found a the thread on evom with the part numbers you were talking about for everything. Thanks.
So you're saying that the IX turbo is MUCH better than just upgrading the 9.8T to a 10.5T hotside then? Are you referring the to the TiAl version or the inconel one? Apparently, there are two types of IX turbos
Since you have an 05 EVO you already have the 10.5 hot side, not the 9.8.... so there is no advantage for you to buying a new hot side for your turbo unless you are looking to get a ceramic coated one and then sell your stock 10.5 housing to someone else.

Waitaminute. How do I know I have the 10.5T hotside?
A check with the dealer has revealed that the car is an MR RS, according to their records.
Definitely an MR - you can tell from the aluminum roof and the JDM DV, which is all original with the car
Definitely an RS - not in the traditional way of the RS -- my endplates for the spoiler are not black, but the door handles and wing mirrors are, the car didn't come with Recaros, has no ABS
"# The well-proven 2-liter in-line 4-cylinder 16-valve DOHC intercooler-turbocharged 4G63 engine has undergone detail improvements. The power unit retains Lancer Evolution's trademark flat torque band that kicks in from low engine speeds but now generates gutsier torque in the mid- to high-rev band.*
# The turbocharger uses a larger turbine nozzle with matching cam profile to deliver higher output at mid- to high engine speeds.*
# The turbocharger waste gate now uses two solenoids. This optimizes boost pressure control to give more stable torque in the low to mid-range and helps the powerplant to generate class-topping torque of 40.8kg-m (400N-m) at 3,500 rpm.*" -- "(* RS 5M/T excluded)"
As such, I'm really getting quite confused about whether my turbo is a 9.8T or a 10.5T. I reckon most of the USDM 05 Evos are 6-speed versions, so perhaps that explains the 10.5T?
No, only the USDM MRs are 6spd - the rest are 5spd. All 05-06s worlwide should have 10.5 hotsides. You may be able to see it written on the housing itself.
# The turbocharger uses a larger turbine nozzle with matching cam profile to deliver higher output at mid- to high engine speeds.*
That phrase right there.... larger turbin nozzle meaning it has the 10.5 hot side (turbin side) rather than the 9.8 turbin side.

PS: You can look on the turbocharger, and it will tell. Sort of hard to see with it installed, but you can use an extendable mirror to see if you can't get a direct view.

Looks like I will need to hoist and check out the turbo somehow. Do any of you guys know which side of the turbo to look at? Or do I need to dismantle the turbo?
If you take a look at the turbo in the e-bay sale at the begining of this thread you will see a flat area on the compressor housing, that is where the information about the turbo is engraved. Look for that same flat area on your turbo compressor housing.

Got it. Will check tomorrow when I head down to the garage to get a mallet job on the downpipe. Hope that 'cures' the remaining rattling and rubbing once and for all, and gives me a chance to check out the plate on the turbo. Will keep you guys posted on which turbo I have.
God, I hope I've got the 10.5T but I'm not going to hold my breath
