Asking for a friend.....
2016 RAM 3500 SRW with a 6.7 cummins with the AISIN transmission. D3leted with a Rac3m3 tuner.....4 inch turbo cat-back exhaust. AFE intake. Banks Intercooler. Lowest possible power tune at 60+HP. The truck has 99k miles and has developed a nasty exhaust manifold leak that permeates the cab. Looking for suggestions on the best replacement two or three-piece exhaust manifold upgrade so this does not happen again.
The diesel shop recommended if my friend wants to replace the turbo....now is the time to do that because its free labor because of the exhaust manifold replacement. What turbo would you recommend?
Currently....my friend is looking at a BD steel multi-piece exhaust manifold upgrade. Would you do this and keep the stock 99k turbo or upgrade?
Thoughts on replacing the stock turbo with a Fleece Performance Cheetah 63mm or 64mm turbo? It's currently hitting 33psi in boost with the stock turbo. There are no head studs done. The diesel shop refuses to install head studs without pulling the head and resurfacing it. I know many other replace the head studs one at a time and others seem to be ok. The shop he uses refuses to do this head stud install. This truck is used daily for towing enclosed trailer and towing an open car trailer. More power is always nice....but more concerned about reliability. Please advise. Thanks guys.
