1986 Turbo K5
5 Attachment(s)
I've had a few request to start a build thread on my K5 I recently built. So here it goes. I acquired the K5 from a family member about 2 years ago, so it's been a slow build. It was originally suppose to be a run about ride for the wife to carry our two dogs. Well that quickly snowballed after I decided to add a turbo to the mix. I tried to make a quick rundown of the parts below. Feel free to ask anything. Thanks for looking!

She's in! It fit really nice. I forgot to mention earlier, I used Dirty Dingo engine mounts. The intercooler shot has got to be one of my favorites. The coldside piping is also starting to come together.

DEI carbon fiber header wrap to help cool things down a bit in the engine bay. Also the fabrication of the anaconda size down pipe. The inner fenderwell wasn't installed in the pic, but is later modified to completely hide the downpipe.

Downpipe wrapped and installed. The blow-off valve and wastegate sensing lines are ran in s/s tubing. The header wrap isn't that shiny, must have been the flash. Cold-side piping painted in wrinkle black paint. If you notice there is a MAF currently installed. This is taken out later on in the build to just use speed density.

Gotta love the Rally wheels. Grille fitment came out good. We only had to take it off about 34 times. :waah:. Fresh rebuild of the NP208 transfer case. We had to install a 32 spline input shaft to be able to slide it onto the 4L80E, so we did a complete rebuild and cleaned it up. New front spoiler also.

Turbo peeking through the grill. It now has a filter on it. 2012 Mustang seat fitment. My old man and my wiring bud helping out with getting it cranked. Last two are of it's first time pulling out under it's own power.

Maiden voyage to a buddies house with the top off of course. Shortly thereafter the roll cage started to be fabbed.

Cleaned up the dash with new trim and some LSX flare. Dakota digital gauges w/ A/F ratio and boost digital readout. Also installed new door panels. Soft top finally installed.

Top rolled up. It was perfect for Crusin' the Coast. Plenty of breeze, but still open to hear all of the cars. For some reason I don't have a pic of the truck tailgate on it. We put a truck tailgate, and installed the blazer trim so it looks like we shaved the grab handle. I'll have to get a pic of it later.

Pop's 53 and my K5 at Crusin' the Coast. Dakota gauges all lit up, the check engine goes away after it starts. Helicopter seat belts. Truck tailgate with blazer trim. Rear seat cover.

After Crusin' I decided to install the 14 bolt I had laying around. It's a 1996 14 bolt semi-floating. It has 3.73 gears with gov-lock. Lugnut 4x4 supplied the brake conversion. That is a Blue Torch Fabrication diff cover also.

Converted the truck to speed density tune, so we had to modify the intake pipe to do away with the MAF. It cleans up the engine bay a bit. Also scored a carbon fiber engine cover. Cleaned up the under carriage a bit.

Gotta represent the Tigers. Took it to work early a few times. Installed N-Fab steps for the wife. (Also helps hide the downpipe) If you have any questions about anything, just PM me. I don't get on here daily, so please be patient. Thanks for checking out my ride! :chevy:

I remember your truck, I think you posted a pic of it once is a Softtopper thread. Beautiful truck and work, thanks for posting details.
|
Yep I posted awhile back about the top.

Re: 1986 Turbo K5
Excellent build, thanks for sharing! On last photo, notice a lot of slip yoke exposed. Do you have enough spline engagement for your driveshaft into the t-case?
|
Yeah believe it or not it actually has a lot more inside the seal. It was a special yoke I ordered for it. I was going to get a cv joint driveshaft but I never had a vibration problem, so I just got the extra long yoke.
