The h23a1 is a decent motor to boost.
*8 lbs is close to its limit for safe reliable driving
*10 lbs can be done but your pushing it
*Don't use and fmu/missing link
*Programmable ecu and injectors is the only way to go
*You don't need a socketed p28 either, a p05/p06 is cheaper/easier to find and works great.

Good luck. L8r
