Best mods for 7.3?
My buddy just picked up a 1996 4x4 F250 with 7.3L PSD with 291k on it for $2700. We were talking about modding it here soon. I know we will probably go with a 4" TB exhaust, but for now i am going to cut out the cat and muffler. My questions are, what else should we do?
--tuner? what brands best? Custom tunes?
--CAI? whats the best for this year truck?
What are the stock specs on the 96? and what can we expect with the mods above? Are the head gaskets prone to blow apart like the 6.0"s?

No worries with the head gaskets till you get bunches of power.
Custom tunes are the best, Beans, TW, DP, PHP, all have good tunes. There are some others too.
Get some gauges, at least a pyro to watch the temps.
Stock hp is 225, tq is 480?? I think.
These trucks are pretty limited on making bigger hp until you change the injectors. The most you'll get is probably another 80 max hp without changing injectors.
You can do as much as your buddy's wallet will allow. Lots of power available in these motors, just takes some cash to get to it.

whats the size of the stock pipe? how big should i go?

Stock pipe is 3 1/2 inches and 4 inch should cover most mods up to 400hp.

Is it reallly worth it to go from 3.5 to 4 in? I am asking because i do not know, not to be a smart a$$

Downpipe is 3" and the exhaust is 3.5" stock. The new downpipe will still be 3", but will be a real round pipe and not some smashed down POS. That's the best mod you can do.
Yes, the 3.5-->4" exhaust is worth doing. It really opens things up. 5" is questionable, but some guys consider that worth doing, too.
Here is Clay's 6637 kit (6637 is the p/n of the filter)
Riffraff Diesel: RDP 6637 Filter Kit
Pyro gauge should be next. Before tunes.
Have your buddy read these forums. There is a mod sticky at the top. Get to it!

oh i thought that he meant the stock DP was 3.5. they are kind of a pain to get off, and being so old i dont know if it'll even come off for me. i know a 4" exhaust really makes these trucks sound good, thats for sure.
He is a mechanic and FORD gear head in training and he listens to everything i have to say, this forum just makes me sound smarter
i'll hook him up with an account on here one day and he'll be able to educate himself further when i'm not around.
