Driveshafts will fit.

You will need a 208 Transfer case that came from behind a 700r4 or Th350 for the output shaft to fit, the TV cable and a TV cable pracket for a 6.2.

That said a 700r4 isn't much of an advantage in a 1009 with the 3.08 gears.

The turbo will also be in the way of the TV linkage, it would have to be fabricated for certain.

Unless you know that the glow plugs are brand new, I'd just get new ones. They are easy to do while you have the engine out and much more difficult with the engine in.

To do a side mount turbo wouldn't be a bad job, couldn't you just use your J code 6.2 heads (with 6.5 head gaskets) and go to a junk yard and find the "f" code intake manifold (remember, it comes in 2 pieces) and make it work?

That seems like it would be significantly easier.

i just bought them from napa, the (glowplugs), i bought them for the 6.2 but the 6.2 i bought turned out to be bad, so i didnt want to return them

i want to go with the center mount to be different, and also because i already bought it and at my pay, its expensive, im rolling with what ive got

UPDATE:
im posting pics tonight, turned over the 6.5 feels smoothe looked all over for cracks found none, the 6.5 is a 1997 GM, a lot of the components look brand new but seems it had sat out for a while, and flash rusted, you know just bearly over the surface, i also took the 90 degree adapter off the oil filter mount, took out all the glowplugs that were in it, they were all in really good shapeim also scrapping out the other engine as ive stripped out all the parts off it, intrestingly enough all the plugs were on it

You can do whatever you want, it is your truck! Sounds like your glow plugs are new, so go with them!

Whatever you decide, certainly post progress pictures.

[EODTECH90]

these are old but im working on it

 

[EODTECH90]

the engine is painted cummins beige, im getting a new power steering bracket with pump, working on this oil cooler situation, the cooler you see in the pic is for the trans, cooler for oil is on the other side,the dash is off and im in search of another, i need to groundhop the motor as it has a new gear reduction starter on it, it will have a 700r4 tranny behind it as soon as i can get this thing goin as it is under its own power, need bolts for the bell housing, going to get new alternators. can you guys give me napa part numbers for the driver an pass side? sorry its taken so god dang long, this is just hard on E-4 pay

 

[EODTECH90]

can i get more info on that oil pan thing i think you are right ALA2 now that i think about it

 

[chevyCUCV]

Awesome build, I love the centre mount turbo's.
I would prefer it over the sidemount because it will equalize pressure between both side of the engine. Most diesels use centermount turbo.
I have also read that they flow a lot better than the othe gm turbos

Cant wait to see it buttoned up, good luck with the firewall

 

[Stonepicker1]

Good luck on your project. Make sure you run it outside in the can first. Hate to see you do all this work just to pull again because of a problem. Better to fix it before the install.

[EODTECH90]

havent seen any cracks, i got to ground hop it but really want the **** thing put together, worst case im just gonna work on the rest of the thing and if the engines bad ill put a 4bt in. ive searched allover the block no cracks so far but ill keep working on it, besides im more concerned with the rest of the truck (lift, tires, interior, lights, chassis, alternators, trans) and other stuff ill keep up with the motor tho, if you guys could help with the wiring on the top of the ip(what wires to plug into it and at what voltages) and advice with what to do with the darn HVAC because its too fat and i want to install A/C eventually, any advice about the oil pan will the 6.2 oil pan that came off the original motor from the 1028 fit on the 6.5 and clear the axel it seems uncomfortably close down there... anyone that has pics of this swap please chime in

 

[EODTECH90]

PLEASE HELP WITH A REPLACEMENT DASH!!!!!! i need one lol

 

[EODTECH90]
