Thanks alot, I found a video and it was pretty choppy so I'm thinking I'll do a vid while turning mine up for better clarity. I have new head bolts already and my question about the NA injectors was that the NA injectors are set at 1800psi pop and TD are from 2100 to 2300psi pop. I have both...

I wanted to update this thread a bit. The motor has been inspected and all is well. There are some very small stress cracks in the combustion chambers that are presumably safe to run this way. The block was manufactured in 1998 and I found out it only has right at 25,000 miles on it after being...

So I've been pondering the idea of just going ahead and rebuilding my other 6.5 What exactly do I need to turn 1/4 of a turn on my 6.5NA IP? Other than that, I'll be good to go with a fresh overhaul so long as the cylinders & everything is good. Any suggestions for the rebuild like certain...

Well the truck has been starting fairly easy without alot of cranking so I never really had a reason to try the cold water yet. I now have another issue, I drove it for about 1 hour and shut it off after letting it idle for 3 minutes to cool. When I went to leave an hour later, it just went...

I also wanted to mention that I installed my new flywheel in about 2 & 1/2 hours by just sliding the tranny back far enough to wrench out my flywheel bolts. This is a 4X4 truck and I wanted to let people know you can R&R the flywheel without a lot of hassle and without removing the tranny. I...

I want to update a little bit here. I ended up having to actually file the starter surface to get my teeth to mesh with the flywheel. This works great & sounds good cranking. I did have to file almost 1/8 inch or maybe a little more to get a good mesh but I figured you could easily shim the...

Yes she has got a few years on her. lol It has 213,000 miles on it & the top end was rebuilt around 150,000. I made sure that the support brace is in place but it's not so much that issue as it is the teeth barely touch the flywheel. I have 2 motors, 3 flywheels, and 2 starters that I've checked...

I have a 93 6.5 TD that needed the flywheel replaced. I just installed it and diagnosed it's failure due to the gears not sinking in deep enough from the starter to the flywheel. Shimming the starter only pulls it further from the flywheel. Any ideas, maybe I need to trim the top of the starter...

UPDATED: I ended up buying a 93 with a 6.5 turbo & a 4L80E tranny and just swapped everything over to my truck because the 93 was rusted in half. Thanks again for y'alls input, now for some more questions... lol I reckon I'll start a new thread.

As far as the wiring will I just need my starter wires, IP wire for fuel shut off, wiring for the glow plug timer, and wires for my gauges? I assume the MAP sensor & the water in fuel & wires as such are not needed?

Thanks everyone for the warm welcome :thumbsup:

Thanks so much, I did read that the TPS was for the trans so I do "NOT" really need the P30 harness at all. :) My 88 only needs vacuum for the power brakes so would you recommend using the hydro assist brake system from the P30? I know the vacuum pumps in my area run about 200 bucks and I'm like...

You are correct ak diesel driver there is only a tps & fuel shut off. With this being known, will I need the ECM & complete harness from my P30 or can I run W/O the tps?

I want to edit my first post, it is a "1995" not the one mentioned. I couldn't edit it and the block number is 506.

I have a 1988 GMC 1 ton dually with a 5.7 currently getting 4.7MPG and a TH400 transmission with rear ends running 456 gear ratio. I have a 1996 P30 Box truck with a 6.5 non turbo that I am going to install in my 88 using a 5 speed standard transmission. This should be easy enough to do...

I drive an 88 GMC 3500 EXT cab 8 foot bed and a few other toys like a 91 Camaro RS, 94 Jeep Wrangler with Chevy IFS suspension, and I'm starting a 1970 Jeep Commando build with a 5.7 vortec.
