Just dropping in to say this thread is mostly over my head, but I'm still loving it.

Their newer variation has the VNT on the common rail engine but is electrically controlled. They hang off the NO4C-TD engine and are callled the GT2563VK ? Would be good to be able to fit a traditional vacuum or pressure capsule to them and set up a dawes valve system.

Just posing the question to someone in the know (Dougal). :D

They work excellently. Ask this guy: Gt2259

It's possible to convert any VNT to pneumatic or mechanical. But if we could acheive electronic control, that'd be even better.

Me again,

I may have my hands on what seems to be a GT3063KLV Garret. VNT, comp A/R of .44 and ex of .74. This has the electronic pizmo on the side of it and would possibly be able to be fitted with a capsule, vaccum or pressure. :D Watch this space.......

Cheers,
Brian.

I did think it was strange that it came off a 4l Hino NO4 engine. I thought it would not realy match with those numbers. It was also a bit wierd that the hino manifold outlet was a vertical rectangle (T2/3 horizontal) but the exhaust flange on the turbine housing was a circle :eek:. There is a soot shadow on the turbine housing where the exhaust gas has been running straight into a wall before re-directing itself into the circular port. Bit strange.

There's not a lot of info on that turbo. Does it match the model codes in this link? GT30V - Garrett - Catalog - TurboMaster

It has the code 765870-1 which must be one of the superceeded models as all the ones on that page have 765870-00 something.

Unless its the equivalent to the one on the first line and they just diddn't include the 3 zero's.
