parts needed to install s366 on my 99 cummins
 

Hey guys I need to make sur I have all the rite parts before I start installing the turbo and supporting upgrades. I already have the down pipe but is there anything else.

nope. long as it is a T3 housing you should be fine. t4 housing would need an adapter plate for the manifold.

Hope you have the injectors and fueling to support a turbo that large...

ok cool thanx and i have the adapter anyway just in case. and ive got 150hp injectors 150 gph supply pump edge comp with smarty. my buddy has all the same stuff but no chips cause hes p pumped his 24 valve other than the p pump everything is the same and his smokes but it controllable. im not worrried about also having it ported and polished everything should be done by next month
