Anybody done it? By my calculations a 20v head on an NG or NF block will yeald about an 8.xx:1 CR which would be perfect for turboing. I would think this would be a pretty common conversion, right? Any thoughts on what kind of fueling/timing syustems would work with this? Sounds like it could be a pretty fuss-free way to do a turbo conversion. Especially if you use a 20v head and the turbo off a 5000 TD which as in integral wastegate so you wouldn't have to use a bent control arm or relocate the battery. It would be pretty much bolt on from what I can tell. Thoughts?
