Military 6.5 na

Hi all, can I install the manifold and crossover pipe to make a nonturbo a turbo? Found one doesnt look like its been started. It's inside one of those metal crates.

You want to change the precups out to the turbo precups. Large turbos vs. the Asthma Attack factory turbo's will make the NA precups smoke bad. The smoke is manageable on a factory GMx turbo, but, still smoke more than turbo precups.

Minor things otherwise to drop it in.

What's involved in changing the precups? Would I have to do that on a teds engine that was a turbo? I found a 98 gm 6.5 rebuild by the military. Found a couple of other military 6.5s they look like new, but they're calling them rebuildable. I looked at the company's web site that builds the new 6.5 for the military. They're the ones who build the optimizer 6500? So if teds engins have double diamonds they're optimizers?

You have to pull the heads to change the precups, but then you can put on arp head studs. I think a 98 will be a regular gm 6.5, not a GEP optimizer.

My Teds engine had the turbo precups already. It is an optimizer. I think the engines are assembled with what parts onhand. It was definatly a NA engine, as the turbo oil return had the part that ran the mech fuel pump. Maybe I got lucky, but love that Teds engine with the ATT ect.

Pull heads. Pop out precups with a wooden dowel through the injector hole. Pop in turbo precups - if needed. You will have to see what the engine has first.

Or if you have time send the precups out to get bored to turbo spec. Slim knows a guy that does it
