ok, people i help with this one! i have most of bolts on stuff on my gp that i'm very happy with. well except headers, but that will come later. anyway this spring i'm planning to install xp hot cam from zz performance. i know you must replace the chain, springs, retainers, and gaskets. i'm thinking while the engine is tearing apart i'm gong to go ahead and replace roller lifters, valve locks, push rods, and valve seals now is this neccessary to replace these parts or it's just a waste of money? what about intercooler do i need it so i don't get kr? if i do need intercooler i'm thinking about the short stack intercooler, cause that fit my budget. last question will my stock transmission be able to handle all this power? do i need stall converter? or what kind of mod i need to do to the transmission?
