Re: Possible to turbo a 3.0L Duratac DOHC 24V?
If you want to add a turbo to an engine that's not designed for it, throw cost out the window as it will be a custom modification. That said, unless you want to do some major mods, leaving the engine stock you'll only be able to run 3-4psi of boost safely without causing engine damage. The pro's aren't worth the cons in this case, but yes, it can be done. Most supercharger/turbo packages add around 8-9psi of boost and claim no engine modifications are necessary. It's one thing to run boost, and it's another to run boost safely.
If you were expecting 10-15psi of boost, you'd have to tear down the engine and upgrade the pistons, injectors, fuel pump, upgrade engine cooling, head gasket for sure, I know I've left some parts out but those are the most costly. On top of that, you'll have to recalibrate the computer and the transmission will have to be upgraded to handle the additional torque. Another wise choice would be to slightly stiffen the front suspension so as to better put the power to the pavement with as little wheel hop as possible (read: torque steer).
The 24V is a good engine but I don't think adding a turbo would be worth spending thousands of dollars on, even if you want to do the work yourself.
