I know.. I just cant decide.

We are only talking a difference of 3-4 years (at least in my case). I am looking at a 93 idi or a 96 stroke.
On one hand I like that the idi can be fixed with basic tools....simple and easy.
On the other hand I like that I can slap a chip on the PSD and be ready to rock.

At this point, Im leaning more towards the IDI because I wont be towing any super heavy loads and the truck will be used for road trips and to play off-road.

I really do want a PSD but Im afraid I dont have the income (work for a small rural sheriffs office) to repair such a vehicle should something large go out.

thoughts? GO!

7.3 psds really dont have much go out if kept stock or just a chip.

play off road? lol. something is gonna break anyway, reguardless of year. road queens are best with less wear.

Id trade my 95 for a 93-94 IDI in a heartbeat. My IDI towed loads just as heavy and just as well as my PSD, albeit a little slower, but beats my PSD any day of the week on low end grunt right when you put the foot to it. I absolutely loved my IDI, and was very upset to see it go. Plus they sound absolutely incredible straight piped. There is an IDI that runs around here with dual miters, and it sounds just great. my choice would be the IDI

ya our idi has done well. and the towing too.

Shoot man good luck I'm thinking about going from.a built cummins to an idi talk about a lose of power Haha.

I ended up with an IDI and love it!

let me know when you are in town so i can blow by ya in a 6oh....




pics man!

The idle validation switch must not have been adjusted right because the PSD is WAY stronger and more responsive than the IDI motor.

With adjustment of the idle validation switch, PSD's can almost be too snappy on the bottom end.




.

OBS PSD's have large exhaust housings, and take some rpm's for the turbo's to spool. Couple that with compression around 17.5:1, and the IDI with 21.5:1 compression allows the IDI to eat an OBS on the bottom end. The PSD's lower compression is offset by higher boost pressures, but because of the large exhaust housing, it takes a second for the turbo to fully spool up.

N/A Diesel's will always have snappy off idle performance due to their compression.

Anymore this is how I think of the 7.3IDI vs. PSD debate goes for me. If I wanted a truck that I would use for work (think like ranch truck, always has crap in the bed, dont care about body, etc) I would get the IDI. If I wanted a truck that has a potential to make good power, I would go for the PSD. If I did buy a PSD, I would buy a nice one, therefore not use it for work (hauling is ok, but not like the work above^^^). I feel IDI's can take much more abuse and keep going than a PSD. And even if they cant, used IDI engines can be found for way less than a grand.

lol but you wont be able to sneak up on me...I will be able to hear the sounds of failing head gaskets from 2mi away
