Sounds good, however: is the engine is probably worth $10,000 knowing the
Jap tuning shops, and 11.7:1 is definately aviation fuel territory. The
VG30DE would probably be a better choice for all-out naturally aspirated
grunt since the US guys get upwards of 250hp from these motors (pretty stock
too). Not a cheap conversion though! It's much more cost-effective to go
with forced induction for big power.

powered by SR20DE, tuned up to 200ps@7200rpm, 21.8kgm@4800rpm, linked to a 6
speed close ratio transmission with 4.08 final gear ratio in a 1420kg

Throttle response of such NA motor might be appreciated by discriminating
drivers.
