Its something a little different. Twin VNT turbos on an A12. probably wont make a lot of power. More something that looks OK. Ive always wanted to have a play with a VNT turbo.

This one will be a slow process, but ill update as it happens.

Already looks awesome!!

Variable Nozzle Turbo is not supposed to make more power, but rather to make almost the same power, yet with far less turbo lag and extended torque curve

And twin turbo is supposed to be more efficient across the range using a tuned manifold (having two cylinders feed each turbo)

So why do you say it probably won't make much power? Are the ones pictured not a good size for the engine?

How are you going to control the VNT.

It probably depends on which ECU I use. If I use the elCheapo, I'll probably use dual port wg actuators, with one side referenced to MAP and the the other to EMAP. If I use the good ECU I'll probably use servo motors. Regarding boost control, I'm tempted to vent on the cold side(if turbo speeds can be kept in check. I don't really want to have to run two wg's as well!

I've done some basic calcs DD, with two, they will probably come on at about 3800 to 4000 rpm on the A12. They are off 3 ltr diesels. I'm tempted to test one on the engine that's on the test stand to learn more about what 2 will be like. It's a lot of work to set up both properly to find out it was a waste of time.
