Just have to gather all the parts but you can for sure convert it back to turbo. Hopefully the other engine is the turbo engine. You may have some of the parts to convert it back if you got parts with it. The exhaust manifolds, fluid tank, air cleaner, valve covers, and turbo system can be located if you don’t have them. I have not got a quote yet for the intake. I do have a turbo exhaust manifold if you find you need one.

Hi Pere,
The simple answer is yes. You could replace the 4 barrel carburetor system with a turbocharged intake and induction system. As Eric stated, it would require all the parts unique to a Jetfire engine to be found and installed. Not being sure of your intentions, you have all of these parts on your Jetfire engine on the white car and could remove and use those parts.
The Jetfire engine block has longer bolts (stronger) used for the main shaft bearing caps to hold the crankshaft in place stronger connection rods and different pistons to achieve higher compression ratio of 10.25 to 1 for an automatic transmission set up and 10.75 to 1 for a 4-speed manual transmission set up and special bearings. The heads (T) for a Jetfire are different with aluminized valves and a smaller dome cavity size to increase the compression ratio. This all adds up to a stronger engine to handle the 6-1/2# to 8# boost added by the turbocharger.
If you really wanted to just add the parts to your 1961 F-85 (not Cutlass) engine installed in this 1962 red Jetfire body, they will all fit and work. You would be sacrificing some ultimate power and engine strength offered by the Jetfire engine, but it would work/run. It would just be not as offered by Oldsmobile.

Looks like that one is not a Jetfire engine either. You may post a picture of all the parts. Maybe we could point out some Jetfire specific parts if there are any? I guess you may already know what you are looking for since you have another Jetfire.
Hi Pere,
Sad to report, like Eric said, this engine has heads from a 1962 two barrel carburetor, low compression, plain F-85 engine, not a Cutlass or Jetfire. I don’t believe the block is Jetfire either. Is this the extra engine you bought with the red Jetfire or the engine in the white Jetfire?
