So im purchasing a trick 76/75 turbo kit. Will LSA 52# inj be enough for what I need? its a 5.7LS and will only see 10#.

 

Go bigger.

10lbs doesn't really mean anything. An engine with 7psi could use the same amount of fuel than a engine running 10lbs is, it's all in the tuning. You'd rather have more headroom instead of running it to the edge.

Think 60-70lb/hr to give you an extra 80-100hp of room to work with.

 

Thanks for the info. ended up going with 72#
