We finally throw an exhaust on the 1992 7.3 f350 one step closer to being a daily driver again!

Great to see people making good content on IDI’s would like to know more about the turbo so I can put it on my 93-94 but in the passenger side wheel well, keep up the good work!

[@Grewsum2Sum]

Hx35 wicked wheel coldside, hotside is 10 blade hx40 with 18cm (1.0 A/R) exhaust housing. So basically tweaked hx35/40 hybrid lol

[@mikecorleone6797]

That’s funny my 1990 f350 7.3 crew cab 4x4 is named *Blue Chungus* 😂

[@BRIANVANDUYN]

Hahaha nj is seattle lol love the build so far !

[@darjohnsom9368]

I love that truck, Id love to have it

[@tractorboy31]

Wow such a wimpy exhaust. This spring when my trans went out on my 97 7.3 i had the shop put my 5 inch system on. The fun part is its for f250 and f350 pu not the cab n chassis. Well mine is a c. n c. so its axle dumping for now. I had to get a new downpipe since i couldnt save it from my 94 7.3 ps f350 that got totaled. Im starting to get the elbows to build a tailpipe. I love the cab n chassis so much better than a pu. 11 ft bed but only a standard cab. Its a 4x4 dually which wasnt available as a dually pu

[@wreckerjonny6144]

My f450 exhaust is true dual exhaust . It does not have a turbo which is bad lol. But plan on running that for awhile til I get the other engine ready to go . That's going to be inter cooled and has that Cummins turbo on it

[@Grewsum2Sum]

Nice just watch out if it's a stock hx35 the hotside will actually choke an idi because it wont let it flow enough

[@johnnyohness6610]

Love the hell out of your guys' videos. I hAVE A 94 idi TURBO that I would love to bring to you and let you do what you did on your truck. Would have loved to see how you made room for the exhaust down pipe and see what a difference it made in the interior floor. My 250 is a nice clean piece, but 100% stock automatic. I've seen purists say over and over don't try and stretch these engines, but you seem to have it all buttoned down. It's been some time since you did your upgrades and this is the third or fourth time I've watched your vids. You are truly an inspiration to me. Just wondering though now that you have a few years on the build, have you had any problems? Just wondering. Your Centurion looks so awesome have always loved those chrome pull handles on the outside. Mine is just an XLT with a single cab, but that's what I have to work with. If you were doing it all over again would you do anything different besides leaving the trans attached to the engine on the pull? Has the truck been as reliable as you had hoped it would be? I'm assuming you did all your dealings with R&D remotely, instead of taking your rig to Washington. I've called them a time or two but never get through to them. Would love to hear how your build is holding up. Would appreciate any comments.

[@Grewsum2Sum]

Build is holding up great! No problems except the clutch can't handle the power ! I will be building it up even better very shortly

[@BRIANVANDUYN]

Just bought a 89 idi f350 check it out on my channel i plan on doing 40 over injectors and a turbo soon

[@classictruck.confidential]

Awesome build man, I’d like to talk to you more about the motor if I could?

[@Grewsum2Sum]

Go for it what would you like to know

[@classictruck.confidential]

Grewsum 2Sum what’s it cost roughly to build a motor like that? Also what’s your mpg like and how’s it stack up to a 7.3 or 6.0 ?

[@airstreamxtreme5838]

Looks great. Can you explain a little bit more about the CDR Valve replacement? Won't it get dirty with only the pipe? Oh-... you ever thought about a dyno run? I'm curious how much power you got!

[@Grewsum2Sum]

What's gunna get dirty? Lol a bug may crawl up the tube if they dare, but I dont think anything else could really get up in it

[@Grewsum2Sum]

And yes dyno will hopefully happen this summer

[@TanNguyen-vo9nz]

Hi there is your truck have powerstro?I have my 1993 Ford f350 turbo but no strol

[@trevorrisley5419]

Alright, man, I’ve learned that my dream truck is a ‘94 F350 Turbo 7.3L iDi with a 5-speed and extended cab. But what I don’t know is a damn thing about workin’ on diesels. Or even how diesels are different than gas engines. Besides watchin’ all of your videos, which I am and will, do you have any specific recommendations for an elementary level learning for diesel mechanics then going up from there? Thanks, dude!

[@Grewsum2Sum]

Just watch a bunch of videos and read some stuff on the internet about how mechanical diesels work. But the best way to learn, (just like how I learned) is by forcing yourself to do something you don't know how to do and figuring it out in the process. When we first got this truck, we had just about the same knowledge as you do when it came to diesels

[@vee950]

She's PIPED LMMFAO 😭😭😭😭😭

[@camelotdream]

Any plans to address the hot air intake? There is some efficiency to be had by not sucking in air thats well over 200 degrees off the back of the rad/intercooler. Not a lot of room left but just wondering if anyone else has some ideas to get the intake to a cooler place or if you would use baffles/shields to direct cool air up there?

[@Grewsum2Sum]

Might play around with that when I do my fuel system and re route my charge pipea once the stock filter head is out of the way

[@camelotdream]

@@Grewsum2Sum Cool, just was wondering what you where thinkin. When I go turbo on my truck I want to think of how to do that to get better power and keep those EGT temps down. Your truck sure burns clean for a IDI. Did you notice an improvement (less black smoke) with the better breathing fromt he turbo? We did water/meth injection of our Maxxforce POS's at work and that eliminated tail pipe smoke and improved fuel economy enough to make a difference in fleet costs.

[@Grewsum2Sum]

@@camelotdream watch our dyno video she doesnt burn that clean lol

[@jeffflanagan2814]

You have a link for the exhaust kits?

[@Grewsum2Sum]

I just found the cheapest downpipe back kit online for a powerstroke and made it work for my truck

[@johnnyohness6610]

@@Grewsum2Sum What did you use to open the path for the larger downpipe? Hydraulics...or just beat it open? What difference did it make in the floorboard on the passenger side. Maybe not much at all? Can the stretching/opening to accommodate the new downpipe be done with the engine intact...or does one have to remove the engine?

[@tommybragalone7943]

Why the muffler?

[@Grewsum2Sum]

Idk I like the stealth, sounds stock

[@tommybragalone7943]

Grewsum 2Sum ah. This is one of the cleanest idis I have ever seen. Very nice truck. You better keep it forever lol

[@Grewsum2Sum]

@@tommybragalone7943 oh I plan on itt lol

[@offroadspecialties7383]

IDI's sound terrible without an muffler. They get all poppy at high RPM under load.

[@camelotdream]

@@offroadspecialties7383 Any diesel ESPECIALLY a Cummins just sounds like mechanical barfing without a muffler.
