I'm going to be going to pickup a 91 CTD 4x4 727 with just under 200K. It's not intercooled. I wanted to find an intercooled model but I cant pass up the price on this one. It looks like its pretty well cared for and I've already got him down to 1,500. What's it like trying to get a little extra power out of these. I know the heads are differant. I've read about puttinga PS intercooler in and I've already found one. What should I know about this motor.
Thanks, JJ

 

most non ic trucks will run circles around ic'ed trucks.

Stock for stock of course.

 

I've heard they are real good, easier to get a little more pwr being they come stock with bigger injectors than the I/C models... For 1500 bones, sounds like a steal.. Just get some guages first then start adding the fuel. A p/s intercooler would be a great addition..

 

Very easy. They will run circles around intercooled trucks with stock injectors.

 

i like mine, with a tuned pump and 60 comp wheel i can pull several lengths ahead of my dads 01 with an edge ez. both manuels, his 3.53, my 4.10s.. They will get toast very quickly. needs an intercooler or water.

 

How do you guys think the D60 rear will hold up in the crew cab. I dont plan on going wild with this thing. It's going to be more so for the wife to drive.

 

I was gonna let my wife drive mine all the time too.... untill I got it done!!!

The 60 should hold up good, they are pretty strong axles.. Never had a problem with mine running 44" boggers..

 

I have one of each; my stock non i/c will run circles around my lightly modded i/c 93...

 

Not only do you get big injectors in the non i/c trucks but I SWEAR 727's have tighter converters then the 91.5-93 A-518's..

You'll love the truck even more once/if you add an intercooler,cuz then you can do more tweaking., dont forget you could always add a factory i/c setup from a 91.5-93. you have a 91 with the newer grille so it can be done.

stock non i/c injectors are good for up to 350HP+ they just need air/exhuast to do it.

 

absolutely love it rips plenty of power and fuel

 

Thanks for the info guys. Keep it coming.

 

A modded N/IC truck with an I/C make for a very fun truck

 

ive been meaning to ask you about this, how fun and what improvements did it make on egt's, lookin to put a ps intercooler in mine and want to know where you got your 24v intake horn???

 

i'm interested in hearing more. i have a non I/C'd that now has an I/C in it. my 4" exhaust will have to wait til next weekend and my intake will follow soon. i only have the pump tweaked about 3/4 of a turn though. i wonder how it would perform with a denny t stage 2??? i bet it would spin the duals

 

I Don't know if I can put a measurement on fun but the fun does last longer

Before the I/C I could bury the pyro in the blink of an eye, now the egt rize a lot slower and sort of level off at 1400 but do creep up slowly after that, this is all with my winter tune, we'll see what happens when I put the big sticks back in and fart with the pump again

Improvments were a 200ish degree drop at wot, 100* at cruiseing speed and 50* at idle

If your truck is originally a N/IC truck I've heard that a 2nd gen cooler fits a little better than the PS cooler, The PS ooler fits btter in a I/C'd truck

I got my 24v horn from a guy on this forum named Papecat, he also bought my old crossover that rbrettctd made

Within the nextfew weeks I'm gonna try to wedge a 2nd gen cooler behind my Old style grille
