Possible Engine Build for my 93 Truck

[dbrannon79]

Ran across this marketplace post with a 6.2 for sale locally for $250. Supposedly the vehicle caught fire in the cab and has sat for 10+ years since. What do yall think? Would this possibly be a good investment to get an engine for my 93?

It might be worth a try. It wouldn't take much wiring to give it a try. I'd probably wire in an electric lift pump before trying.

That's got to be, not a whole lot more than scrap price. If it's a no go, scrap it and get a good portion of your money back

 

[Paveltolz]

If it turns over and you can at check with compression tester before you drop the money, it could be worth a shot. Won’t know unless you try…“He who dares, wins!”

I figure it must have one heck of an oil pump! the video in the post shows the guy turning it with a ratchet and oil coming out from the cooler line. if it's been sitting for that long I would think the pickup tube would have drained out and need to be spun faster to get any oil movement.

Sent a message. we will see what the fella says

 

[dbrannon79]

curiosity has me though. if the engine is good, what all i would need to do to swap. since mine has a turbo and iirc NA engines don't have the proper pistons or coatings for running a turbo. mine also uses the crank sensor on the front like the newer ones for the TCM, will the timing cover from my 6.5 fit along with the sensor wheel that's under it.

I know it will be a downgrade on power going from a 6.5 to a 6.2, but I would think that's like the difference between a 305 and 350 which is not much. I don't need a power house, just want a good running dependable rig!

You'll be fine without the coating as long as you don't get crazy with egt. Everything else will interchange.

6.5 is just a bored out 6.2. most don't report noticing any power difference. If it's in good shape might even see a power increase.

That is what I was thinking! mine is so worn out that this 6.2 might dance circles around it LOL

Balanced injectors vs unbalanced are a far bigger impact to power than 6.2 vs 6.5.

I wished when GEP started casting they went back to the 6.2.

Bring some old oil incase he doesn’t have enough in there and a compression tester.

 

[Paveltolz]

My engine is a 6.2 N/A 599 block bored 30 over. 6.5 heads. Mine didn’t have ports for either the OPS in the valley or front of the block for turbo oil feed. If the one you’re looking at is the same, you’ll need to make a T-Block fitting for the OPS and Turbo Oil Feed line using the oil port at the back of the block. I used brass to ensure proper ground for the OPS.

 

[dbrannon79]

Yeah, that is the same as the cracked 6.2 that i picked up a couple year ago. there is some sort of restrictor fitting in the block there that's tee'd off to the turbo on it. did you need a restrictor on there not to get full flow or pressure to the turbo?

 

[Paveltolz]

No restrictor was used. You're the first one to mention it. Given the OPS port isn't restricted and, so far as I know, the Turbo's Oil Feed Line on the 6.5 isn't restricted given the amount of oil that came out of my old 6.5 engine's port when left open once (no I don't want to discuss it).

 

[jrsavoie]

The bypass filters I've used were all restricted.

one other thing I just thought of, that came out of a square body. I believe the pan is different to fit the IFS. you'd need to source (or make) a pan to fit.

 

[dbrannon79]

Would the pan on my current 6.5 fit on that block? I have the other 6.2 that has the cracked main webs also that is complete with a pan. hoping this engine turns out good, once I get it all together and ready to install, I can post up all the remaining parts if someone needs them.

if the pan that's on the engine will work, I will leave it and the current 6.5 intact, inspect the 6.5 to see if it's a viable rebuilder. might be good to fix up for a spare drop in engine.

 

[ak diesel driver]

The issue is 2 piece rear main seal vs 1 piece.

 

[ak diesel driver]

IIRC there was 3-4 years they used the 2 piece with the IFS

 

[dbrannon79]

Yea I forgot about that. the 6.2 I have that's cracked is a two piece rear main. Hopefully the pan will clear the cross member. the burb it's in I believe is a 2wd, so is my 93.

 

[dbrannon79]

I guess Once I get the engine home and all, I need to start making plans to have the IP rebuilt and ready. not sure who I should use. if all works out, I would like to get one rebuilt, then later get the one that's on the 6.5 done too. with this engine coming home with me, I will have a total of three DB2 IP's. wonder if someone can rebuild one and have it ready for the 6.2 and maybe have some instructions on what to do or how much to turn the fuel screw so it can be spec'd for a 6.5 later down the road.

Maybe it would be cheaper on my end to send all three in to get two good ones back with them keeping one for them to rebuild and sell.
