7MGTE and 7MGE engine blocks ???????????

You are right about the oiling systems in the engines, they are good. The thing with the oil squirters in the turbo engine is that they are used for cooling the pistons even more than the oil holes in the rods. The cooler and the lines help keep the oil cooler ever so slightly and really are there to help transfer some of the heat from the pistons under long boosts or hard boosts.

Use a synthetic oil in the engine and that will help too. I try to use the old 10 psi per 1000 rpms guage with oil pressures. Everyday driver cars usually don't quite make it, but should be close. A manual guage is best for keeping track of that.

Suprra girl told of an N/A with a turbo and stock N/A compression. Just keep the max boost down a little more. Instead of 15, go for 8. The N/A revs up so much quicker because of the compresion, but I just don't know if the stock N/A pistons can handle the abuse. Maybe a quality aftermarket piston, but most go for lower initial compression, but it is not a rule. More compression equals more power, just watch for detonation and use very good fuel and make sure your knock sensors are working. That is why the turbo engine has 2 of them and the N/A only has 1.
