Spare truck manifold, worth porting?
A buddy just put a fast intake manifold on his turbo 5.3L
Gave me the intake manifold for helping him out.
Any gains from a diy porting job on the nbs truck intake manifold? for my 5.3L
I ported my tb a while back tad bit more top end and slightly better throttle response.
If I was going to go through the trouble of doing this I would go ahead and get some 42lb injectors for future turbo build.
Is it ok to run bigger injectors 42-60lbs on N/A 5.3L with a new tune of course
I saw a thread were some body ported their ls2 manifold no deeper than 1" and gain a solid 20hp and 21tq on a LS2 though
