Re: non turbo 7.3 vs. reg. 7.3

Want to say something inside the turboed motors is suppost to be beefed up. Diffrent injectors & pump. In all truth though I would trust a NA motor with a turbo more then a factory turbo motor. Can't remember what it was but something they tryed to beef up didn't work so well & have been known to spin a bearing in the bottom end.

IDI & HEUI don't go together.

Re: non turbo 7.3 vs. reg. 7.3

NA 7.3 IDI was 21.5:1 compression ratio.
turbo 7.3 IDI was 19:1 compression ratio.
powerstroke was a whole different engine.

Re: non turbo 7.3 vs. reg. 7.3

For all this time I was under the impression that the factory turbo trucks had better rods, but this got me thinking and questioning myself, so I did some digging.

Found this...

The biggest improvement and most sought after option for 1993 was the introduction of the first factory turbo option. This option was available for the two remaining years of IDI production and is significant for several reasons. From the very beginning of the 6.9 liter production, a turbocharger was considered, but the normally aspirated engine was already a $2000 option and the addition of the turbo would nearly double that figure. Many believed that the extra amount on the sticker in the mid ‘80’s would put it over the edge price wise. Luckily, companies such as Gale Banks Engineering, Advanced Turbo Systems (ATS), and Hypermax saw this as an opportunity. ATS was chosen as the turbo system provider for the new factory turbo option and Ford/Navistar implemented other engine upgrades to compliment the addition of the turbo. Trucks equipped with this engine option can be identified by the small “Turbo Diesel” emblem under the F250/350 front fender badges.

The additional engine changes are as follows:

Cylinder head gasket heavier ring and armor wrap

Increased wrist pin bore on connecting rods

Larger wrist pin

Anodized piston head

Keystone design top and intermediate piston rings

Increased number of oil passages in oil cooler (30 fin/inch vs. 24 on NA)

Turbo specific flywheel

Turbo specific vibration dampener

Turbo injector pump

Turbo injectors

Modified injector fuel return line routing

Modified E4OD dipstick

Modified E4OD turbo micro processor

Turbo specific cooling fan clutch

Lower restriction exhaust

Additionally, the truck received a slotted front bumper and an air dam below the radiator. These improvements conservatively raised the power output to 185hp and 360ft/lbs of torque. These numbers are believed to be under-inflated so as not to downplay the mid year introduction of the new diesel engine.
