[Es2] 20v turbo'ing

NG/NF Block (10v High Comp)
7A Head (20v High Comp)

Those two together should yield around 8.5:1 compression if I remember
correctly.  There is loads of talk about this combination with the 034EFI
guys on that forum.  I know of one motor that is this combination on a rally
car, Paul Tingaud, and it ran quite well.  He also had a 10v turbo block and
20v 7A head combo, 6.5:1 compression and something evil like 40lbs of boost,
undrivable in any conventional way.  Personally I'd just save my pennies and
my headaches for a 20v turbo motor.
