2.3 NF block with MC-1 head?

[Mihnea Cotet]

Oh right, he was talking about making a turbo 2.3 10v.... bad idea indeed,
only maximum 5 psi are possible with some very high octane fuel and much
retarded ignition timing... However, lowering the CR a tad to say 9.5:1 and
a pretty good ignition control system would allow him to have a setup
similar to the 20vt... not a very bad idea! I'll try to look into making a
9:1 CR 10vt with a good ignition system (accurate is the word, I have the
timing values for 20vt engines so transposing these values on the 10v
engine won't be the issue, accuracy of the spark control will instead) and
a nice turbo as well... sounds like fun anyway!
