The build sounds pretty good to me… Though there are a few things I’m unsure of…
The crower cams you have are for NA, correct? They probably won’t be the best choice for going Turbo.
Secondly, what are the specs on those cams compared to a stock LS cam? If the lift/duration is significantly bigger than the stock LS cam, then you run the risk of dropping a valve. Over-lifting the cam springs are a big no-no. You usually want to match the spring to whatever cam you’re getting… IE: When you buy the crower cams, buy the crower springs… When you buy Skunk2 cams, buy the Skunk2 springs, etc.
The exhaust/header/testpipe is kind of small… 2.25"? You should run at LEAST 2.5" for turbo, if not 3" all the way back.
But for the most part it seems like you’re on the right track. Do you have any clue of what turbo you are going to run? If not, you need to decide on what kind of power you want, that will determine which turbo you want to run.
well my car is also my daily driver for now, so i want to run a single turbo at around 10 to 12 psi, thats all i really know rite now, do u have any more advice
Saying what PSI you want to run doesn’t really tell us anything at all. You need to know what kind of power you want to achieve. For instance: An HMI (DSM) t25 @ 12psi is going to be significantly different than a 60-1 (60 trim) @ 12psi. The t25 @ 20psi (not exact numbers, just trying to give you the idea of what i’m trying to say) would make the same power as the 60-1 @ 12-14psi. Also, i would ditch the NA cams. Stock LS cams have seen some pretty decent numbers. Hope this helps.
ok, thanx but i think im just going to swap my b18a1 for a b18c
