IDI stood for indirect injection - a type of combustion chamber. DI is the direct injection that ford ih and cat developed with the high pressure oil pump, to shove the fuel out of the injectors at super high psi (16,000 psi iirc)
Thats when ford coined the powerstroke term. Made it in some '94s, but considered to start in '95.
'83 6.9 started with 160 hp, and 307 tq. Last year of 7.3 IDI turbo'd was up to 190/400.
Last year of the similar 7.3 powerstroke ('03) was up to what? Double a '83 6.9?
I think they were 275 / 550 at their peak. Maybe 250 but can't remember for sure. Autos got one rating and manuals another.

The banks kit is apparently still available for $3500.

Also, addressing the IDI vs the 7.3 powerstrokes and power:
A turbocharged IDI will run dead even with a STOCK early 7.3 powerstroke. The factory turbo '94 IDIT's will not, however due to the fact that they were watered down from the factory. The theory (and probably fact) is that Ford didn't want to take away from the glory of the powerstroke coming out a year later. An aftermarket turbocharged IDI feels sportier than a stock PSD.
My '88 with a banks sidewinder would pull a similar load right with an early powerstroke. I had the fuel dialed in to where you could flat foot it eternally and it would sit at 13 PSI and 1200 deg on the pryro.

Stock for stock, correct. And correct on the reason.
Aftermarket to stock; sort of true, and there are reasons to stay with a hopped up IDI.
But considering what the aftermarket could do with a DI, no comparison.
Looks like it disappeared from it's spot but it's also firewood season so it might be back
Speaking of strokes, holy Berkeley do people still hold them dear. The very newest ones are almost 20 years old but a lot of their following are dudes not even that old themselves. I guess it's the sound?
