So I know you can't use a 6.5 turbo setup on a 6.2 if you want to keep AC. I am not familiar at all with either engine. What I was wondering if anyone has moved the turbo (what I understand to be in the way) on a 6.5.

It is too much work to do. Custom piping for the turbo is not a big deal.

Anyone ever done or looked at doing this. Let me know
 
I think the problem is the passenger side exhaust manifold, the turbo bolts up straight to it and is in the way, you would have to modify the manifold.
 
If you want to retain the stock A/C setup in an 80's truck you have two options, either get a banks manifold or build your own. Stans headers does make exhaust flanges for the 6.2 as they make headers for it as well. The banks part pushes the turbo to the very front to the engine. The link shows the install fourwheeler did a number of years of a complete banks turbo setup.

If you have the turbo you want to run and the welding skill you can make your own. But if you're only going to run a stock GM turbo just run the banks one if you can find it. Would save yourself a lot of time. Also remember that if you're going for big (for a 6.2 at least) power, over 250hp, I HIGHLY recommend an intercooler. The 6.2 has a stock compression of 21:1 so anything over 12lbs boost and no intercooler WILL melt the pistons. With an intercooler you can push it to ~17lbs boost. That's at stock compression, if you build the engine with low comp pistons, around 19:1 and use head studs you can push the boost into the upper 20's.

These numbers are sustained not peak. My truck for comparison runs around 23lbs of boost but I'm at 18:1, head studs and a duramax intercooler. So the egts easily stay in check. I'm also running as stock 6.5 setup so I removed my stock A/C( stupid me :doah:) and installed a vintage air unit that puts everything under the dash. That's a GM8 turbo, the largest GM every put on the 6.5 from the factory. The filter is 8" long and the ic piping is 3.5od, just to give you an idea on space available. And yes the intercooler does fit but with some pretty serious mods, but very well worth it.

Hope that answers you question, probably gave you a bunch more though :haha:.

That is seriously cool, is that a Cummins grid heater I spy there and is it functional??If so did you get rid of the glow plugs? What kinda power you putting out? Thanks for the pictures.
 
thanks Kirsl, I will probably run the A team turbo. Those guys are in Boise so almost local to me.

Not really looking to make a ton of power really, the turbo just makes sense on a diesel thats all. I would like a some more power for sure for long trips and steep hills but I am not going to over do it. It will depend but I will more than likely keep the boost pretty low to maintain dependability. In the future things may change but that will be a while when I can afford to go through the motor myself.

When I do that I will use a newer 6.5 though more than likely.

I actually planned on running an intercooler for a couple reasons. There plenty of space to put it and once again it just makes sense to run an intercooler if you have the space.
 
Sixb- Thanks. You spy correctly, that is a cummins grid heater and it does function. I'm using a momentary switch to engage the glow plug relay that's right next to the oil filters. Still have the stock glow plugs and mainly use them. The grid heater helps but I've found that it's best to use the glowplugs before start up then use the grid heater. Least that's what my engine seems to like. Power I'm guessing is around 230 at the rear wheels, at or over 300 at the flywheel. One day I'll dyno it to know for certain.

The A-team turbo seems like it should work really well for a stock comp motor. I'm planning on running the stock turbo off my 03 Cummins once I get a better one for that. The GM8 turbo is also good when used within it's limits (I'm at/beyond it limits) and they're fairly plentiful and cheap.

I would agree with knowing the complete condition of an engine before going to the limits I've gone to. Otherwise things could get expensive quickly :eek1:.

I had wanted to run a 94-02 dodge cummins intercooler but the prices were crazy on ebay when I was looking. I bought the duramax one for a 180 bucks, not too bad I price I think. Either one is going to require mods to both the intercooler and the core support.

Plenty of space huh, heres's where I had to move my oil cooler to due to lack of space. You can see I also opened up the support fro more air flow through the intercooler and radiator. I had to do a fair amount of cutting behind the lower drivers headlight too.

here's with the bumper on. It hangs down 2" from the edge of the bumper and actually ends up even with the bottom of the frame rail and goes all the way back to the first crossmember. Its made from 1/4" 6061 aluminum, very strong and wont ever rust :woot:.

Now the reason I had to move the cooler was it's an 1.5" thick, so it wouldn't fit behind the factory grill. Plus I needed and had to run the a/c condenser where the oil cooler was. I need to get some pictures of that to show how it'll mount. Still have to run the a/c lines, so I'm running out of room fast :whistle: :haha:

In case you guys haven't noticed I tend to go a little overboard when building things. :haha::screwy::woot:
 
Very nice indeed, i'm running the 1st gen dodge I/C and do have room for everything barley, mines a 5.9 CTD in a k5. That is the first hot rod 6.2 I've seen, almost makes me want to keep/build mine in my truggy instead of going with a 5.3/6.0. Thanks for the ideas and pictures you bastard!! hehe lol.
 
Modding the core support is not such a big deal to me. I plan to actually run the trans cooler in a different spot with a fan in order to free up some room for the intercooler but like I said it will be a while before I get around to doing this.

Initially I will just grab a stock turbo and plumb it in. All the intercooler and the A team turbo will come after I am happy with the turbo setup overall when I rebuild the motor.

I am also going to experiment with electric fans, not aftermarket ones, OEM models that will help free up some room.

Maybe I will build a bumper with some holes in it like the IFS 6.5s had :D

I do plan on a large plate bumper for this truck and have thought about adding a couple frame rail coolers in those to help with trans and oil. Put some inlet holes in them and that leaves more room for ac condenser intercooler and radiator.
 
Thanks. Yea it does get pretty tight :eek1: with all the stuff in there but with careful planning it all fits and looks like it belongs there too. There are some hot rod 6.2/6.5s out there but not too many, it is costly when the gains can be small. I've given a cummins conversion some serious thought a number of times over the years (I've had the truck 10 years) just haven't fully decided that is what I want. I have my dodge to do the heavy hauling duties so this truck can be little crazier. Plus I love the fact that most people don't hot rod a 6.2, which makes it cool :pimp: at least to me :D :screwy::haha:. The cummins is an awesome engine (love mine) but it's not really hard to make really good power with one. The 6.2 takes some ingenuity and it throws most folks for a loop when they see what all has been done to mine. I would totally rock a 6.2td in a buggy, would be great on fuel and give good power when needed. The only way I wouldn't run one was if I was building a full race rig but that's a whole different beast.

Just have to remember to reinforce the core support when you do cut it, can get pretty flimsy. A turbo with intercooler will make it seem like a completely different truck. I also had considered cutting holes in the bumper like the 90's truck but I decided against it mainly because I didn't think I would get the airflow that the oil cooler needs, even with the fan. Plus having the retain a front plate meant the holes would of been pretty small. I haven't used the truck in summer heat yet, but I think the oil cooler will fine under there. It's barely noticeable too unless I point it out to people. The plate bumper idea sounds pretty cool. The space that's right under the support can fit a pretty big cooler or two smaller ones.

You guys need any ideas just hit me up. You never know I might of come up with crazy idea for it already :weld::grind::screwy::haha:.

Also to me, a cummins in my blazer is just too much really, I would really gain a bunch of weight I don't want, besides that I need to put a cummins in my crew cab if I ever get a hold of one.

I would throw a 6.5 in Horton so fast it would make your head spin. Just Gotta find the right deal. Almost had a guy trade me a complete truck with a 6.5 turbo in it for Hortons engine (stock TBI 350) but he backed out.

I truly truly think in 2-4 years time gas prices are going to be near 5 bucks a gallon if not more, diesel will probably be near 5.50. Making Horton a perfect candidate to do veg oil with too. :D
 
Blazers aren't as bad as a shortbed pickup but even they're nose havey as it is. The 6.2 is right around the weight of a BBC and it bolts in with minimal changes to the chassis.

Diesel buggies/truggies are sweet :D. Running one on biodiesel and/or veggie oil makes then even cooler.

Both my toys are diesel and my tow rig is gas:doah: You SOB's have got me thinking about keeping the 6.2 with a few mods of course:woot:

Well if you do and you machine some fancy custom parts to do it, you should probably make two of every part :whistle: I'm just sayin :D

You are a little backwards David aren't you :haha:
