Picked up a 99 rcsb with a 4.8 looking to do a turbo build probably around 8psi what supporting engine work should I do to hold it

I wanna say all you need is a tune and more fuel, but I'd feel guilty if you butt a ring, how many miles on the engine?

ChrisJohnson

Don't know exact but it is a higher mileage engine closer to 200k

I think a walbro 255 and some 60lb injectors+ an aeromotive regulator and a good tune and youre good to go.

Probably gonna have to do some work on the 4l60 depending on your luck, probably easier and cheaper to go 4l80/th400 or just pick a new 4l60 than to try and make one live forever

Is it worth grabbing a cam of a different ls motor ? Also I have a buddy with trans shop so I was gonna send it out
