Sorry to bump an old thread;

What exactly is the difference between a T67 and a TD06SL2-25G using Mitsubishi Nomenclature would they be the same thing? don't think that Greddy/Trust or Mitsubishi ever marketed a TD06SL2-25G though.

I know for what Trent said in the past the housings aren't interchangeable (the mating flange is different on the Core or something like that?), so you couldn't use a 8cm TD06SL2 housing on a T67. But as far as the wheels go they are the same thing, and would flow the same?

Well a 25G wheel is a 25G wheel, there are a few different comp covers avaliable for them, but the only real difference between them ins the size of the inlet snout.

T67 runs the L2 turbine wheel, once again a few different housings around, but no major differences there either.

Have a look at the table here: http://www.supraforums.com.au/forum/under-bonnet/37485-td06-25g-turbo-kit.html

There's a:

TD06SL2-20g

T67-25g

TD06SH-25g

I've can't recall seeing a TD06SL2-25G. According to that table the TD06SL2 has a smaller compressor wheel than a T67.

TD06SL2 depicts no compressor wheel what so ever, it is the figure after that which tells you what compressor it has. IE 20g or 25g.

From what I know, T67 is simply the marketed name TRUST used to sell the TD06SL2-25G. As stated, on paper they are the same.

As people have said, TD06SL2 refers to the ass end of the turbo and 25g refers to the compressor wheel...

A "T67" refers to a TD06SL2 25g

Yes your're right.

Although, never it labelled as a TD06SL2-25g, only have seen TD06SL2-20g & T67-25g

I haven't read the whole thread so far but I will later .

With Mitsubishi , or MHI if you like , they call basic turbo sizes by turbine families just like Garrett does .

Instead of being GT28/GT30/GT35/GT37/GT40 etc MHIs will be TD04/TD05/TD06/TD07 etc .

From what I read a MHI T67 is a hybrid of a TD06 turbine with one of the compressors normally intended for a TD07 turbine based turbo .

The TD06SL2 turbine is some sort of ground/altered turbine I believe originally made for Trust to get a bit more flow than the TD05H turbine can give . Its basically made to fit in between the largest TD05 and smallest TD06 turbines - Hi Flow turbine for TD05 turbos like the OE Evo 4G63T ones .

They are probably not a bad thing on RB20's but I think something in the TD06 family would be better on an RB25 or larger engine .

I think I posted diagrams of the TD06SL2 and a few of the other TD06 turbines in the last MHI turbo thread here .

Did Sir Stripey Horse even buy a TD06? It's the first Ive heard of it... And were both 1JZ boys.

I think these T67 items are a set result really, quite predictable.. The one making 260rwkw is on 17psi, which is relative IMO.

Zebra, what did you get and how dare you keep it from me :(

Decided on the 25G after looking a a heap of different results on 2.5L motors,

the 25G makes full boost a bit later in the rev range, but doest come on as hard and sudden as the T67, seems a bit more progressive.

Idealy I will get both the 25G and the T67 and go back to back to see which one I like more.

As I said earlier though, If I stumble accross the right RX6 I'll nab it instead of the TD06

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
