I'm going to buy a F54 shortblock assembly to buildup. Since this is going in a turbo car, I want to use a more durable piston (forged). The goal is about 350 hp. What else should I concentrate on for durability? BTW, the price I got quoted at the quick and easy junkyard is 125.00. Could find one cheaper but it seems like a fair price without having to wait. I'm going with the T03/T04b super "H" additive and a Starion intercooler to start with.
