The pistons you mentioned are forged replacements, stockers are cast, good choice but make sure C/R is down to 7.5 to 1 or so for detonation protection.
You will need a modified intake manifold to add intercooling and FI already know this probably. Probably easier to start with a 3.2 Carrera manifold unit as mentioned above.
You are gonna need alot of oil cooling so get a front mount cooler that mounts below front bumper. Everything else will not get enough airflow to cool properly.
I assume your reference to valve spring replacement is to use a stiffer spring and properly shimming them.
Does the Carerra manifold set up bolt up to my engine, or can it be modified (as I own a machine shop)?
I assume most people add the front oil cooler and retain the wheel well cooler?
