#1  How hard is it to install a turbo on my 2.2 carb, 2.2/2.5 TBI automobile?


If you're starting from a carburated application it's the worst- just for the work to the body of the car you have to get an EFI fuel tank, turbo fuel pump, modify the wiring harness in the car for the pump, change the vehicles front wiring harness (usually something from a model that has a turbo that's close to yours) knock holes in the firewall for harness runs (logic module) and that's before you even started looking at the motor!  Turbo engines share very little part numbers with their non turbo counterparts.

Here is a list of parts that are the same (depending on year of course)

Intake valve
Connecting rods
Cam/crank sprockets (NOT ALL, see this page for a breakdown)
Crankshaft (not same part number but interchangeable)

That's about it as far as parts that are the same!  Even the transmission, suspension and brakes are different!

If you really wanted to swap over your current motor to a turbo and skip doing it right you would still have to get a turbo, intake and hardware (throttle/kickdown cables & vacuum hoses) turbo exhaust manifold, turbo camshaft and springs, turbo exhaust valves (carb/TBI exhaust valves will burn up in as little as 6 months) and bore holes in the back of the block for oil & coolant returns from the turbo.  After that you would have to lower the compression of the motor by stacking headgasket shims which will throw your cam timing off (or change to turbo pistons and rings.)

If you REALLY have your heart set on swapping a particular car over to turbo power the best thing to do is buy a turbo wreck that's close to your car model and year wise and swap out all the parts.

Reliant & Aries
400/600 & Lebaron sedan 
Omni, 024, Rampage
GLH & Shelby Charger
Shadow & Sundance
Shadow ES & Sundance RS
Caravan & Voyager
Caravan Turbo

Please note that this list isn't all inclusive, just a rough guideline to give you ideas!  (I know not all Shadows, Sundances, etc.. are non-turbos)  You can use the turbo motor & trans from another body (If your lucky enough to get your wiring done), they are all pretty much the same except for the Omni/Chargers (L-bodies) which have unique axles, shifters and motor mounts due to their narrower bodies.

I know I swapped the k-car over to a turbo engine and make it sound easy but I have YEARS of experience working on FWD mopars not to mention a garage full of parts to pull it off.  Even then I was working with an EFI model car (If it was a carburated car I would not even have attempted it)  which already has the EFI fuel tank, firewall knockouts for the computer wiring and other odds n' ends that make the job easier.  I still had to swap over brakes and suspension from my wrecked Daytona so the job was done "right"  (I ended up cutting coils off the front springs because of the weight difference between the two cars, the Reliant used to sit up like a 4x4 in the front)

I'm not trying pee on anyone's parade but it's much less time consuming and cost effective to find an existing turbo car and go from there.

#2  How hard is it to install factory EFI on my 2.2 carburated car?

See above. Your pretty much in the same boat as trying to swap over to a turbocharger except you can use everything on your current carb motor except for the intake manifold.

#3 Is there any books or literature on how to do a swap like this? (see question 1 & 2)


Ths Mopar Performance 2.2 book doesn't cover it at all and the factory service manuals do not either.
