I'm still not sure what this turbo is in terms of trim, but I have the part number from Mitsubishi

1515A055

No pricing or additional information was available at this time.

 

does the USDM evo9 have the same turbo as the JDM evo9??

 

Not sure on that one, I do know that this is a completely different part # from the 2003 and 2004 cars. 2005 had its own part # and this new one is different than the 2005. I don't have anymore info yet, but I'm hoping to get the details soon.

 

Heard that once u turn boost above stock levels the magnisum wheel explods, causing damage to engine?? But they are currently engineering some fix for it...heard this from a mechanic who deal directly with Japan Tuners.

But I heard it, didn't see it.

 

Wow. I'd really like to know more about this too. I've heard of problems with the Evo IX turbos in Japan, but have they not been addressed? I'm probably going to get an Evo IX turbo very soon, and am wondering if I want to risk getting the JDM version.

Here's what I know:

US-Spec Evo IX (All Models) Turbocharger: 1515A055
- O2 Housing is the same as 03-05
- Uses 10.5 Hotside like 05s do
- Has a different CHRA than 05
- Has a different compressor housing than 05
- Dealer list price is $1795

JDM Evo IX (GSR/LS Models) Turbocharger: 1515A054
- Utilizes a magnesium compressor wheel
- inconel shaft

JDM Evo IX (RS Model) Turbocharger: 1515A059
- Utilizes a magnesium compressor wheel
- TiAL shaft

I can only assume that the JDM versions have the same O2 housing and 10.5 hotside, but I've not been able to confirm this as of yet. I would really like to know exactly what is inside the US-Spec Evo IX turbo (Mg wheel?). I'm guessing they just revised the compressor housing and kept the inconel shaft like they did in 05 models.

Can anyone provide insight into the Mg wheel issues? The TiAL shafts seem to be a great idea, but obviously nobody wants to sacrafice reliability with the Mg compressor wheel.

 

Easy peeps! This report came from the UK. lan Evo forum. .. I'll try and find a link... it's on here somwhere.

Anyway, the mag wheel only let loose on rally cars running over 1.5bar, possibly with ALS. This is not even what reportedly caused the faliure. It turned out to be a lean spot in the A/F mapping. Why this took out the compressor wheel, I'm not sure but maybe the turbine let lose first.

Suposedly fixed

 

JDM EVO 9 turbo part numbers:
TD05HRA-16G6mC-10.5T: 1515A059 (RS model)
TD05HRA-155G6mC-10.5T: 1515A128 (MR RS model)
TD05HRA-155G6C-10.5T: 1515A130 (MR GSR model)
I verified these part numbers off my Japanese Mitsu ASA prog.

 

Another newbie brings it back from the DEAD again.
