Hey Francelle, good to see your making progress on your motor.I agree with Richard on the lifters.Light lifters are an advantage,yes. If you insist on running the 356 lifters with turbo you will have to re-think some things.Titanium valves to reduce weight and therefore spring pressure.But how will it hold up in the long run? In your 103x88 (iirc) application you are forced to run a cam with a 1" or smaller base circle which makes the ramps steeper and harder on the valvetrain,more spring pressure is required to keep the lifter on the cam.That's one reason why I gave up on the 3 Liter turbo project and switched to a 2320cc 102x71.If I ever do decide on more power than the stock crank and rods can cope with I will just go with the same size crank but in billet from Moldex and Pauter rods.All of which is unlikely to happen...
Next question is: why do you want so much oil pressure? What do you expect to gain from it? I would concentrate more on cooling.60-70psi is plenty.
What main bearing size do you need? Std?
