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? :humm:

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

no idi from the factory was down at 17:1 comp. the full run of idi from 84-94 ran 20:1 to 21.5:1

the turbocharged IDI's were

they wouldnt run. way to low for an idi. would never start below 50 degrees.

The Plot thickens :pca1:

u dodge boys need to go back upstairs, let us rest down here at the bottom of the forum. lol

So what, Don't tread on your thread ? :moon::moon::moon:

Suit yourself, I have only owned 2 NA IDI trucks and 1 Turbo IDI truck.... what does this silly dodge boy know besides he wasted time and money on them old junk fords.:moon:

if u dropped compression down to 17:1, the engine will still start. but it would need to be above 50 degrees. and lots of cranking. one company did this, they did have a video of starting the truck at 50 degrees. took 1.5 mins of cranking to start without ether.

they NEVER came from the factory with 17:1 comp.

the first gen powerstroke 7.3 was 17.5:1 comp.

To the original poster, Yes you can, I have had the stock turbo set up off a 94 IDI on my 92 for almost 10,000 miles now with no problems, and I love it... I would sugest getting a new downpipe as the factory one sucks, get some gauges, turn up your fuel, and adjust the wastegate, they're set to 5 or 6 lbs from the factory I'm set to 8 now. To adjust it you need to remove it because the turnbuckle is pinned from the factory so it needs to come off and have a tap run through it, then put it back on the shaft to where it was and roughly 9 turns will get you to 8 lbs, ATS claims 3 turns per pound. Try not to lose the clip that keeps the actuator rod on the waste gate, it will fall off then you will have no boost and a LOT of black smoke (don't ask how I know).

deieslcawler and rjjp are both right. I'm still not quite use't to turbo straight pipe whistle but then I never turn on the radio either.

He im new to the board and rjjp spoke about a new downpipe for the turbo install on an IDI. Does anyone know where to find one or do you weld one up yourself.
