Well, im a noob and im thinking about boosting my BONE stock Ls..also wondering about how much it'll cost(3-4g?)..im wanting to get a t3/t4oe kit(probably used), and i plan on boosting stock block, looking around 250-300whp, plan on getting a good tune.

i did a compression test and it help 155-160..havent done a leak down test yet.
car has about 145k miles, hasn't been ragged on, stock clutch still pretty good.

also besides the kit, what eles would i need, like..clutch, fuel rail, injectors, intercooler, etc.
thanks
