New to IDI

[Powersmokein]

Hey guys some of u might know me I have been on the .org awhile now ,I had a '97 F250 powerstroke that burned up (and burned my house down)in Feb., WELL now Iam looking at a 1990 F250 ext. cab 7.3L IDI , I basically know NOTHING about the IDI's and what you can do with them. Can you turn the pump up like on a common rail cummins? how hard is it to drop a turbo and intercooler on 1? do they have performance injectors for a IDI like a powerstroke?? these r just some of the questions going through my head. ANY info is welcome, thanks.

You can turn the fuel up. But I heard it can lead to head gasket failures.

Yes you can turn up the fuel like a p-pumped cummins, but the Stanadyne pump is fairly weak, so you wont see a crazy gain in power.
Since these trucks are IDIs and fuel goes through a swirl chamber they just dont have the same high-power potential as Direct Injection engines have.
Turbo kits are a bit pricey and they only give you about 10psi of boost.
I dont know of anyone who sells of has installed an intercooler on an IDI, but i'd imagine you'd have to fab up your own pipes.
The IDI will never be able to run with an OBS PSD, but it will make a strong reliable truck. Plus the 7.3l IDIs sound mean straight piped without a turbo.

I absolutely loved my IDI, and wish I could have found a nicer one when I was looking, I'da bought another IDI before my stroke.......You can turn up the pumps, get some bigger injectors and slap a banks ( i know) or ATS turbo kit, and you'll have a strong truck. IMHO, i'd go NA and run fuel only...... My old IDI had much more bottom end grunt than my stroke.....power right off idle, no spool up needed. I miss my 93....

So you wouldnt drop a turbo on it? hmmmm, what'd it sound like? I dont think I have ever really heard a IDI

I love the way my IDI sounded, straight piped was awesome.....and I love the simplicity of them.......and me personally, no I wouldn't drop a turbo on it.......I like the throttle response of N/A engines.....

so it was quicker throttle response without a turbo? what about pulling?
