Alright so im putting a twin turbo kit on my 91 gta with a 350 tpi. I was wondering what to do as far as internals in my engine. I want to know if a forged steel crank will last or if I need something stronger. I want to push about 14 to 16 lbs of boost total. I think as far as rings, pushrods, valves, valve springs Im going to put in titanium. Also are forged pistons and rods good enough? If I wanted to push full boost which is 27 lbs what would be the best internal setup to achieve proficiency ?

 

This is impossible to answer because no particular detail was given regarding application and usage, rpm and power goals, etc

Where did the boost numbers come from? What about 14-16 lbs or 27 lbs is special?

Everything will be determined based on a set hp and rpm goal. From there the system can be spec'd out and parts selected
