The engine. Forged Pistons do not have the hole to utilize a TT oil squirter, not to mention a forged piston will contact the TT oil squirter. The non turbo squirters squirt oil at the bottom of the piston and non turbo Pistons like forged Pistons do not have the same oil hole as the TT Pistons. So since the piston is not utilizing the hot oil being squirted at it, is it really needed, or would the engine benefit more from higher oil pressure.
