Reply With QuoteThey work excellently. Ask this guy: Gt2259Originally Posted by goanna_shire
This turbo gt2259 from a hino NO4 has compressor A/R of 61 and ex side of 47. What sort of map wouls apply to that sised turbine. Would that size end up spinning the comp out of eficiency too early and turn into exhaust brake? Is it too small for our engines? They run them in the NO4 hino's at work wich are 4lr 4cyl engines. 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).
Cheers,

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