[QUOTE=67_C-30;2895674]If it is a cylinder truck (like mine was) the tranny crossmember will have to come forward and the front driveshaft would have to be from a V8 truck. QUOTE]

What does that mean?

**Palf70Step** · 09-19-2008, 04:24 PM

I think he meant 6-cylinder truck. They have the tranny/clutch housing mounts back further that the V8 trucks do.

67_C-30 · 09-19-2008, 07:38 PM

Duh! Sorry about that! Palf70step is right, I meant 6 cylinder truck!

djw32 · 09-21-2008, 11:00 PM

Is the motor sitting in its final resting spot? If it is, did the front end sag at all from the additional weight from the diesel to the 6 cylinder? When I had the 6.2L in place of the chevy 350, the front drop about 1.5-2.5 inches... What springs do you plan on running?

thanks, David

Yes, I mounted it permanently yesterday. It did drop a little, but I'm going to change the front springs to level it out like 72Freak did on his. The BBC mounts worked out great, and it has plenty of clearance everywhere. Here's a few pics of it installed.

Good job man! Cant wait to hear it run!

djw32 · 09-23-2008, 01:55 PM

Look at that! Good job. This is a 6.2 with the turbo parts from a 6.5L, right? Keep up the good work.

Yes, it is '86 J code 6.2L from a military CUCV with '93 6.5TD parts on it.

djw32 · 09-24-2008, 01:49 PM

Are you going to run the 86 drive assy, or are you going to upgrade to the 89 serpentine system? Thanks for the pics.

For time being I'm going to run the V belts just for the fan and alternator. The military set-up is different that civilian, and I'm going to run dual belts on the alternator. I have a serpentine set-up from a '97 6.5TD that I'm going to put on it when I put on the A/C and the hydroboost setup.

67_C-30 · 09-26-2008, 08:10 PM

I started building my exhaust this evening. I am going to run a 4" mandrel bent custom system from the turbo back with the Warpspeed straight- through design muffler. The factory exhaust housing on the rear of the turbo is restrictive and causes a lot of back pressure on these GM-X series turbos. The inside of the casting measures a touch under 2.600" at the outlet and is more restricted than the where the 90 degree bend is. I decided to build a custom system that will be 4" from the turbine housing back. I machined the flange at work on the CNC, and I'm building the pipe from pre-bent 90 and 45 degree pipes that I will have to cut and butt-weld to the straight lengths. I am going to run outside of the frame rail due the position of the turbo and the narrower frame on these year trucks vs the newer ones that the 6.5TD were designed for. I'm planning on turning it out right before the rear wheels on the passenger side. Here's a few mock-up shots.

thirdstreettito · 09-26-2008, 09:06 PM

Good work! But no stacks?!?!

Spray-Bomb · 09-27-2008, 01:58 AM

Where in Alabama do you live ???
I think I need a vacation & would love to come work on your truck

We have to do some black smoke pics

djw32 · 09-27-2008, 07:16 PM

Looks good.

djw32 · 10-06-2008, 06:30 PM

Any updates?

67_C-30 · 10-06-2008, 07:05 PM

Yes, I was actually about to post this. I finished up the down pipe today. I FINALLY got the pipe fitted and welded top the flange. It took quite a bit of persuasion to make it fit all the way around due to odd shape of rear exit of the turbo. The opening is bigger than the factory opening so there is no overhang. The ended up being a little over 4.5" at it widest point and around 3.5" at its smallest. It is still WAY bigger than the inside of the cast. The last shot shows how wide open the exit is. It makes a nice smooth transistion down for a 90 degree turn. The rest of the exhaust should be pretty straight forward.

LOW DOUGH · 10-16-2008, 04:33 PM

nice

djw32 · 10-21-2008, 11:31 AM

I was looking over the pics again...this is one clean build. Whats new in the south? any updates?

thirdstreettito · 11-19-2008, 08:43 PM

Updates?

67_C-30 · 11-19-2008, 11:20 PM

I have to do a few little things before its up and running, but its close. I always slack a little during football season. We have been real busy at work and my side business and I've spent several weekends over the last couple of months in Tuscaloosa cheering on the Tide!!!

missmy72k20 · 11-25-2008, 12:05 AM

Awesome truck, hopefully I will be following in your footsteps.

Keep up the good work!!!!
