quick question
next year im looking to turbo my is300, im not looking for massive boost but i want to upgrade my internals just to be on the safe side, does anybody know if its true that that the turbo supras had forged internals or not? as ive come into possession shall we say of a set of con rods and pistons and a crank lol

IS200 Turbo project now just about complete ! See my thread here and leave your comments.
Now running standalone Syvecs ECU and no stock ECU !

I was/am looking at 400bhp turbo conversion with no internal mods and running on same compression ratio!

The main difference is that the GTE block has oil squirters to keep things cooler, I have read about people in the US running 600bhp without probs on stock NA internals.
