well im relatively new to diesels and im looking for the best mods to achieve at least 350 horsepower im using the truck for some towing but mostly play. I only paid a grand for the truck so i would like to keep the budget down as well. Any advice on doing this is greatly appreciated once again its for a 93 f-250 idi 7.3L mostly stock jus has the pump turned up a little according to who i bought it from.

i asked a buddy of mine with an old 7.3 idi who knows a hell of alot more about them then i do and he said you can make it till you blow it up and send the rods out the fenders. it wouldnt be a daily driver then and you would need either to start it up. if your just looking for some more power add a turbo that way you will be able to run with the first gen powerstrokes.

to make 350+ with an idi you need at least 10k my 93 idi makes 350+ with all hypermax internals $3500, banks sidewinder tubo $2500, PPE boost valve $25 for a duramax but can be used on any wastegated turbo, i can achive 20lb of boost, dp stage 2 injectors $1000 ,hypermax custom ip pump $1000,port polished heads $150, custom made arp headstuds $800, 6.0L k&n fipk intake $300 custom fitted and 6inch stacks $600 ,and a $1500 for all the other odds and ends think i mentiond everything and it is not really a daily driver. if ur truck is an automatic you better kiss it goodbuy and spend 4000 on a new built tranny and transfer case and if your truck is a zf 5 speed you need south bend clutch $1000 and a NP271 transfer case $800


in my opinon if i was u i would buy banks high ram intake, headers , dynomax exahust and tune the ip pump all for under $2000 and you will be around the same power as an early frist gen power stroke

Trying to make a lot of power with a normally-aspirated diesel doesn't make a lot of sense. Can you do it? Sure, in theory. But you're going to just burn a bunch of fuel, and probably spend more money trying to get there in the process than if you put a turbo on it. I would look into some bolt-on turbo options. But even then, the limiting factor is going to be the stock compression ratio. Normally-aspirated diesels are generally in the 20:1 range. Most turbodiesels are in the 14:1-18:1 range.

Turbo, injectors, custom pragrammed chip not something just bolt on, Exaust, and intake will take you well over 400. But dont forget tranny!!!

I'm trying to remember that old hot-rodder's saying. It's something along the lines of "How fast can I go?" to which the answer is "How much do you want to spend?"  Smile

would the turbo from a 95 96 7.3 bolt onto the naturally aspirated idi? and would the z5 trans hold upto 400 horses?

how about the whole 7.3 from a 95 or 96 would that bolt in place of the idi relatively easy?
