Hey guys i have been looking around for a 94-97 'toy' with cummins power for about a year now and i dont have an abundance of cash to play with but i found a 2WD, Rc, 91 CTD /5speed thats in my $3000 and below price range. Of course the body is beat up (not rusty)in that price range and i was not expecting to find a jewel but i may have found a true diamond in the rough anyway?? this pup only has 130K on it also so I'll be willing to bolt on a few fenders and find a bed. I know nothing about a 91 and the VR?? style pumps but is this 91 even intercooled??
I know a 91 has the huge 21Cm housing and a 16 cm is the cheapest all around alternative and relatively cheap if i remember.
I read Dave's (Wannadiesel) signature and I think i would be happy with 400 HP in the end. wannadiesel says he needs more air now and does that mean a bigger intercooler? turbo? both?
Without reading through every thread on DTR about bombing early CTD's and the arguments involved (errr I meant opinions) is there a good step by step way to bomb a 91. I mean if you are basically starting from a good longblock, that you DONT want to remove the head on, then where do you start besides having dave kill the KDP that is :-). how about some idea on pricing.
Also i did a little research and found that the fenders and hood on a 91 are the same as the 81-up. I was wondering how tough it would be to go to the 86-90 style grille(personal preference and it needs it anyway). anyone done this swap?? a donor front clip is most likely the easiest and they shoudn't be too tough to find in a U-pull-it. thats enough questions for one thread, thanx DAVE CROSS
BTW- can anyone tell me why i don't get the thread notifications at my home email?? i have the correct boxes checked off?

 

91 was the split year. First half was non intercooled, second half was intercooled, so you'll have to physically look under the hood to tell. If it is intercooled, you won't be able to revert to the old style grill because the intercooler physically won't fit behind it. If it's non-intercooled and you're looking for 400 HP on a budget, you might better keep looking, 'cause you're gonna need some sort of cooling for sure. In any event, POD's, pump tweeks and a hybrid turbo will have you knocking on 300+ at the rear wheels. 400hp is gonna cost 'ya.

Make sure it's intercooled if you want to make 400hp. Email- could be your ISP not allowing instant notification.

 

thanx.
In the pic i was sent the air intake to the turbo runs right over into the right fender so i have to assum that there is no intercooler. From what you are saying though if i leave the 91 style nose alone I have the room to add a factory intercooler . I see large intercooler for sale all the time from later trucks and it has NO A/C and with my fabbing skills i should be able to make mounts.
Wannadiesels sig states that he has POD's, 3200 RPM spring, AFC lever ground, AFC pin butchered, HTT Stage IV/14 wg turbo, Snow Stage II water/meth injection - and one 5" stack and that he gets 328 HP so i have to assume thats about it for this style of 5.9 engine(type of pump) even with an intercooler cause his is a 93
thanx for the input, DAVE.

 

If it's NON-intercooled, there will be a crossover pipe connectiong the turbo outlet to the intake manifold that goes directly over the top of the rocker covers. It's hard to miss, as it says Dodge Cummins Turbo Diesel on it and is the first thing you see when you open the hood. An intercooled truck kind of hides the outlet of the turbo down near the passenger side fenderwell and sends the charge air to the IC from there. While nobody can argue that it's easier and (somewhat) cheaper to get big numbers out of a p-pumped 12 valve (94-98 model years) don't tell that to the handful of folks putting well over 600 HP to the rear wheels with our little VE pump as the heart of the machine. Also, don't rule out that torque value--850 ft/lbs will get most anybodys attention

 

I have personally ridden (sp) with Dave , and those numbers are LOW IMHO . Those numbers are from a non load dyno. I have smacked my head on his rear window when he touched the loud pedal in 5th @ 50+mph

I would love to have a set up like his. OK enough kissing up for now, but Man, what a cool truck he has

It's the torque that does it. The dyno doesn't lie.

 

wannadiesel, since i can't post pics here can you send a pic of the top of your engine to my all4trux@snip.net email address. .
I'm prolly going to look at tthis some time tomorrow if it's intercooled. thanx, crossy

 

Why can't you post pics here? There's no rule against it.

There are pics of the engine in my gallery. Right click on whatever one you want and select "save as" and you'll have it.

 

This is BOATNIK's engine- this is with a cooler, this is what you want.

-thanks boatnik

Michael

 

That sentence alone makes me want to spend money...

 

To compare with the picture above, This is a 91 cummins WITHOUT innercooling.

 

It is definetly W/O intercooling but that doesn't mean i can't make noise & black smoke :-) . I guess the basic tweaks are the same it's just that i won't get the same 'net' results?? at the rear wheels and much more limited to overall bombing. I'm sure the truck is a bargain for what is available in my price range . The only question i still have unanswered from you guys is whether the intercooler can be added or was everything different on the N/I CTD? thanx again , crossy.

 

All it takes is some money and good fabrication skills to add an intercooler. Or just a whole lot of money.

 

No I/C = No problem, just one more item to add to the BOMB list !
