2.5 NA block unknown year
NA crank I think
Borla header with custom up and down pipes, 2 1/2 and 3" exhaust
NA intake manifold
800cc sidefeed injectors
Blow through Modded JECS MAF
EBAY T3/T4 turbo
Dyno sheet for 15 psi.. Now hitting 22 psi or so in 4th and 5th gears....
I have made 400 whp on an phase 1 block as well, but due to advanced timing, lost pistons a few times in that one.
Not saying the NA block is the best, just that is can be done reliably.
