Default piston and injector question?

are the pistons in the 1st generation v8's forged? i'm trying to determine how much nitrous i'm going to shoot. also are the fuel injectors the same type as a ford or chevy? i don't mean the same flow rating, but are they the same general size physically? thanks.

It's been a while since I studied the 1UZ-FE. PM Todd @ TM Engineering (DoubleWhoosh). He has experience with nitrous for the SC400 and LS400's.

The pistons are high quality castings. The injectors are not interchangeable with Ford or GM parts. www.lextreme.com can help you with injectors.
