I went with STI block, STI forged crank, ARP studs, factory gasket kit, factory STI timing belt, JE pistons, 11 MM STI oil pump. Rods were Crower/Cobb rods.
Killer B PU

If I did it over again I would have put Mahle 4032 forged pistons in. If I remember correctly that is what they use for most of their builds.

Cobb Plano built my motor and most of what I did was recommended by them, other than the JE pistons.

They use the Mahle pistons in their builds. I saw a over 400 whp car they tuned with those in it and it was quiet as stock.

My motor until warm is pretty noisey from piston slap because of the more loose tolerances needed for the 2618 alloy.

Cobb Plano uses Watts Shop for all machine work in their builds and if you don't know who that is search around.

They broke my motor in on the dyno for 2-3 hours up and down the RPM range and at 10K on it now and 22-24 PSI it uses no oil at all until the last 500 miles of a 3500 mile oil change with Rotella T6 5-40
