Good evening everyone,

Have a few questions regarding sizing and drivability. I use my truck for hot shot and I’m looking to do a gen 2 kit. My question is, should I go with a kit are piece together my own. Also, should I get a manifold with an external wastegate?? My main goal is to keep DP down as well as egt’s. Right now I’m in the process of installing 625 head studs. Will I be ok with stock fuel for awhile??

I’ve recently looked at the steed speed manifold as well as stainless diesels. Any other kits I should take a look at?? How about 464 turbo....to big ?? Graciaaaas
