So my dad's had a 240D for years and now we're making the car he always wanted, a 300D Turbo with a manual transmission. Engine is now in the car but we are having to sort out the turbo as none of the multiple spares I have are rebuildable. One thing my dad is worried about is low end power. He didn't like the turbo lag in his friend's 87 300TD and wants to figure out if we can do something about that for this car.

What options do we have?

We've thought about putting in a Sprinter turbo but don't really know how exactly that would be accomplished. Are there simpler solutions?

We're not trying to make the engine significantly more powerful, just want better low end.
