I've been contemplating a turbo for my 300, but I don't know which one. Keep in mind that this is just an idea for now. If this is a terrible idea, tell me now. I've never messed with them before so I'm not 100% familiar with what's out there but I have a decent understanding of how they work. My diesel buddy is suggesting a Holset HE351CW off a Cummins or another similar 60mm turbo, which I think would be a good choice, but I can't help but wonder if excessive wastegate mods would have to be done to tune down that turbo. I want to run low pressure in the 5-6psi area. (?) Whatever is low enough to keep it on no more than 94 octane and not destroy things.
What turbos are everyone else using? Here's my build so far. It's just a parts collection. I haven't had any machine work done yet.
300 block
240 head if NA or 300 head if boosted. (I have both at my disposal)
240 C5AE non oil hole rods.
Probe 11938 forged pistons with a 20.1cc dish. (CR with 300 head with unmodified combustion chamber is 8.38)
3/8" pushrods.
Crower 19212 camshaft.
Roller rockers.
Cloyes timing gear set.
Full internal balance.
Offenhauser C series intake
F600 HD exhaust manifold
And a Holley throttle body EFI (boost compatible) that I have yet to buy.
