89 crew cab k20 4wd twin turbo cummins swap

[eric28miller]

So after months of research and purchasing parts i'm finally digging in. I first got the motor a few years back from a Case IH agriculture sprayer that i bought and stripped after it had been hit by a train. The sprayer flew 90 feet and amazingly the motor was fine, except for the oil pan, pickup tube, and injector lines. I've been wanting to drop the motor into something for a long time. I finally bought a 6" lifted 84 crew cab chevy with the frame already shortened rust free box cab and 1990 suburban power doors and front clip and 468 big block. But i ran into a big problem.. The vin tag for the dash got lost because a new surburban dash was swapped in and the old one was cut out and, well, it disappeared... Then lucky for me a different guy in town was selling his 89 crew cab chevy with 45k original miles that he bought from the Arizona swat force. He removed the bombproof swat center room whatever you wanna call it and installed a flatbed. What's great is it's never seen salt so it's in fantastic condition, inside and out. I sold the bed for $2000 and the engine for $1500 so i don't have much invested in it. Anyway i'm pretty new to these forums so bear with me as i try to get my pics uploaded and more details will come soon.

Finished motor!


Compound turbo kit is a massive S474 over a phatshaft 62 from industrial injection with a 3 piece manifold. I went with this kit because it's supposed to , as they told me, spool like a mother fuc**er and it looks like it would fit perfect in the c/k body with the large turbo up in front rather then down under the smaller turbo.

The whole truck will be painted chevy volt pearl white. I painted the engine red because it's cummins national color and it came from a CaseIH and it just looks awsome! I picked up the p-pump from a pullin truck that was gettin upgraded to a 13mm, so it already has all the goodies. The original AG pump wouldn't work because it didn't have an automotive governor. The old lines were mangled so i got .093 stainless lines to give it some lope. The injectors are SAC 7x14's should be plenty to fuel the turbos. I am building a little motor to connect to the manual fuel plate so i can adjust it on the fly inside the truck so it will be streetable since it will be my everyday driver. I put an adjustable timing gear on the injection pump to help tune things in easier with a custom made billet cover.
I polished all the chrome work myself, just took it to a guy i know to have it all dipped. It's very cheap if its prepped and ready to be plated. The clutch is a south bend stage 2 which will be bolted to the dodge nv4500 with a billet 1 3/8"'s input shaft and a 1st gen reman dodge 205 with extreme duty bearings and chevy outputs. I'll get pics of it up later.
As for the internals the cylinders have been bored 40 over and fitted with oversized low compression marine pistons. All new bottom end bearings and main and rods bolted together with ARP bolts and studs held together with a girdle. I sent the head out for fire ringing, 60lbs valve springs and titanium retainers and keepers.
Here you can see where the old motor mounts broke off the block when the sprayer was struck by the train, lucky for me i don't need those holes. You can see the article of the accident here: http://www.kcrg.com/news/local/3191126.html

wow lots a work....all worth it cause your gonna have a killer truck when finished......love it....

[eric28miller]

Used a hot pressure washer/sand blaster to strip the frame, then sprayed the frame with a rust converter, then with a rust inhibitor primer, then with gloss black urethane enamel.















While i was waiting for the frame to dry i worked on installing the 2nd gen dodge intercooler. Took a lot of trimming but it fits.

[Devillusion]

SICK BUILD! Pretty much exactly what I want to build.......but never will get to that point I'm sure. Nice work thus far......impressed.

[stepside83]

this thing is sick, cant wait to see more, id love to this some day

[6772owner]

Love how well the intercooler fits/fills up the grille, awesome build.

[odee]

did you do anything to the park-turn signal lens to fit the i/c there? build is great.

[eric28miller]

Here's an update, installed an all aluminum 3 row radiator mounted and a dual feed fuel line for the injection pump.

[eric28miller]

yea i had to cut out some of the turn signal. The intercooler goes inside the light about 2 inches. I"ll have to fiberglass the hole shut when i'm done.

[Mattman2010]

This is turning out awesome. What style intercooler did you use?

[V3500KING]

This truck will sure be sweet when its done. I am interested in how those twins sound when they spool. How many inches did those sulastic shackles add to your lift?

[AllenMC10]

This looks like it oughtta turn out good, keep at it brother, wont be long now... if you ever need any weird or odd parts, i own about 13 untitled but decent trucks, those years like that, ill sell em to ya at a super low price, or hell! Dependin' on what it is, i might give it to you, just ask, or pm me! keep postin pics

[str8axle55]

This truck is going to be sick, when done. Awesome work so far, engine looks amazing.
