I have heard both stories but can a naturally aspirated 7.3 IDI be turbocharged by using the turbo setup off of a 7.3 IDI turbo from FORD? Is the compression ratio or fuel delivery different or why would this be different than adding an after-market ... JOIN NOW TO REMOVE TRACER

Default 7.3 IDI Natural to 7.3 IDI Turbo

I have heard both stories but can a naturally aspirated 7.3 IDI be turbocharged by using the turbo setup off of a 7.3 IDI turbo from FORD? Is the compression ratio or fuel delivery different or why would this be different than adding an after-market turbo?

the setup off any idi will work. my turbo is off a 7.3 idi turboed motor from a 94 f350.

once u get gauges on it, u can turn it up.

Yes it can a buddy of mine bought a non turbo motor to replace his blown up turbo motor. I think all he had to do was use the Manifolds from the turbo motor.

nope, manifolds are the same. the turbos use a dual uppipe that bolts to the factory manifolds.

N/A IDI's were 22:1 compression, Turbocharged 93-94 IDI's were 17:1 compression, over 10 pounds of boost reliability becomes a concern on the N/A motors, Just a FYI
