I'd really like to see some pics of this TD04HL-15T/7 when it turns up , just for the record the HL (which is a turbine size/type in the Mitsy turbo world ) is the largest of the the four TD04 family of turbines and its exducer tip height is quite wide .

There is a little known of turbo in the Impreza Rex world that's quite effective on sleeper Rexes . Its called the TD04HL-15T/6 meaning TD04HL turbine + their 15T compressor in a 6cm turbine housing . At a glance it looks virtually identical to the garden variety USDM/ADM WRX TD04L-13T/6 - but internally ...
I searched the net last year looking for info on this rare JDM Rex unit and best I can tell it was OEM on WRX auto wagons with the EJ205 ? engine .
For the record the USDM/ADM Rex TD04L uses the second smallest or "L" turbine in the TD04 range and thats why EJ20's have off idle response and choke early on their hot sides . Very poor choice .

TD04HL's have been used on Volvos and SAABs at times with either 6 or 7 cm turbine housings .
Mitsy also does a twin scroll version for Subie TS EJ20s and it called TD04HLA-19T/8.5 .
From what I remember reading Mitsys 19T compressor wheel is the largest in the TD04 range and pushes more than the 15T .

Stateside Melett is a good site to search for Mitsy turbo specs so if interested look there .

A TD04HL may not be as bad as some people think , a 7cm turbine housing is a step in the right direction and compressor upgrades within the TD04 range are really easy .

Granted it's not a TS Evo set up but you want to think yourselves lucky if the Evo 10 bits do go bolt , not all manufacturers make it that easy .

How much do you want to spend , cheers A .

 

Does anyone know how much air this turbo pushes per min?

 

You are going to need a compressor map to work that one out .
Some of the Subaru boards like NASIOC have links to Mitsy maps but alot depends on the diffuser size and A/R ratio of the compressor housing itself .

I'll see what I can find tomorrow .

Cheers A .

 

We are impressed so far with this turbo. 252whp/286wtq up from 214/241 so far on some mild tunes.

 

Hi all , in this thred at NASIOC I posted most of what I could find out at the time on the TD04 family of turbines and compressors . My interest was in the rare JDM spec TD04HL-15T/6 , if you go to the first page of that string Soobaviatory kindly posted pics showing the difference between the garden variety TD04L turbine and the much healthier TD04HL one .

That aside the 15T compressor wheel is towards the smaller end of the TD04HL turbines wheel family with 16T , 17T , 18T and 19T all readily available .

Of the top of my heat the 16/17/18T compressors are the same major or OD with the inducer diameter , or trim size , increasing .
Would be so easy to swap in a slightly larger trim compressor and profile machine the compressor housing to suit , externally you'd never know it wasn't std .

I'm getting mixed messages on the 15T wheels capacity , some say 29 lbs/min , some say 450 cfm .
So much depends on how hard bitsafishy tried with the comp cover .

Pics please , cheers A .

 

if the problem is the battery why not move the bat to trunk to then not have it be an issue.

FP was taking stock WRX cores and upgrading them with 18T comp. wheels. I dont see why they couldn't start offering this as an option for the RA if there was enough demand.
