I don't think the plastic intake mani can take boost for long, i mean a boosted engine is definitely gonna be ripped a lot everyday that even 5lbs will eventually stress it to failure.my thoughts exactly....next is power mods...and yes i am thinkin turbo. looking to try to match up manifolds that have the similar bolt pattern and displacement and so far its probably gonna be a K20. i know im gonna be a pioneer with this but i think ill be ok. if a yaris can run 12lbs no problem i dont see why i cant run about 5lbs, im gonna start collecting parts now and start the build after august(gotta have money to go home so i can see my sis when shes on R&R from afghanistan)
