hi pop injectors, intercoolers and gauges

[doncannon]

Hello all,
I have read about the hi pop injectors and I would like to purchase a set, because I am in the middle of my turbo installation. According to the 1997 feature articles and product reviews book page 53 Jim Bigley suggests replacement if over 100k (I purchased from the DP). I have 176k on the truck (8k from me) and I would like not to have any problems after the turbo install. I want to install gauges, where is a good place to buy gauges? Also where can I get an intercooler? if on ebay are they hard to hook up? does anyone have a direct bolt in unit?
Thank you again in advance,
Don Cannon

Hi Don,

Since you say you are in the middle of a turbo install, you must have an older truck, like between 1982 and 1990. I am not aware of a bolt-in intercooler kit for the old body style (1982-1987 pickup trucks - a few more years in 'Burbs and Blazers).

With the extra air you are getting from the turbo, your engine would like to have lots of fuel, crisply and quickly delivered to the combustion chambers. The best pump would be the DB2-4911, with 6.5LTD injectors. Hi-pop will give better atomization and better and faster combustion, and more power.

Several of TheDieselPage advertisers sell gauges for our diesels - click on the link ADVERTISER'S SECTION (http://www.thedieselpage.com/vendors/main.htm) toward the top of this page.

Hooking up an intercooler on an older truck is a matter of lots of complex plumbing in very limited space. If you are NOT going off-highway, you can mount the intercooler below the front bumper - study the story of TheDieselPage's 300 HP Project Truck for ideas.

Keep asking questions, and you will get lots of help from those who have gone before.

I've noticed a lot of people talk about adding an inter-cooler to their turbo truck. It might just be my particular setup but I don't really find it all that necessary. I drive anywhere from see level up to 3,000 feet in a day where I live and find that I do just fine with out a turbo. I see boost up to 15 psi daily with out pushing too hard. EGT never above 900 rarely above 700. I do not tow; I just have fun with my truck. At most stop lights I can give most people a good run for their money. I have a really hard time producing any noticeable smoke, the most I can make is a faint brown cloud and that is from a dead stop with WOT. Do I plan on adding an inter-cooler?, Yes, but I also plan on building a 300HP 6.2. But my current setup could survive with out but If I started spending my time above 3,000 feet I think it would help a lot to create a cooler denser charge. I've also been out on some days where the temps where about 95. My biggest problem is coolant temps not lack of power because of intake temps. I'm not saying don't add a inter-cooler just try it with out and go from there, have fun with your setup. :D

Thank you both,
Are these hi pop injectors different or are they just 6.5 injectors?
I almost forgot I read that aux oil and trans coolers should be relocated from the front of the radiator. Where is a good location? Also, with the external oil cooler how can I plumb the turbo supply oil line, because I believe that is the location I need? Should I just put in a tee?
Thanks again guys for all your help,
Will check the 300hp project,
Don

I was hoping someone else would jump in and answer your questions, it is the weekend and most people me included where out having a good time.
I honestly don't know where to put aux oil and tran coolers. I had a good idea before I installed the turbo, but now the air cleaner box is in the way. I have two tran coolers in-front of my radiator and they don't seem to cause any problems. I also plan on reworking my whole radiator support because it does a good job at blocking air flow through the radiator. So when I do that I imagine the only thing in-front of my radiator will be a cummins' inter-cooler and the radiator will probably become a big aluminum one.
The injectors on my truck are just standard 6.5L TD injectors (brand new) there are ones with higher pop pressures. You'll have to ask Britannic why he choose to go with standard 6.5L TD injectors, because my engine used to reside in his truck until it found a better home. ;)
I'll let some one else pipe in with the rest of the answers to your questions, I'd have to think harder and look under the hood of my truck to answer them and I need SLEEP tongue.gif , but there is an easy answer and solution to your questions.

Don 6.2L long style injectors are designed to pop at 1800 psi, and that is just fine for those that are injecting lower amounts of fuel - less than ~55 cu mm/stroke IMO. But if you're running the fuel for more power then stock 6.5TD short body injectors at 2100-2200 psi pop pressure are the ticket.

You can have injectors built to your specs by most any reputable rebuilder, and a pop pressure of 2300 psi would be very nice so long as the DB2 can handle the pressure of two injectors per cycle - that is, can the DB2 handle 4600 psi of head pressure and live a long life? Maybe.

There are also high flow/high pop injectors available, but the general consensus is that they aren't ideal for applications fueling less than 80 cu mm/stroke and making 300 hp or more.

As for the aux coolers, I run both my engine oil cooler and ATF cooler in front of the AC condenser.

When thinking of the oil supply for your turbo, you'll want a high pressure tap like the one above the oil filter. Banks uses the 1/4" NPT plug just above the oil filter for their oil supply. Late 6.2 blocks (#599) and all 6.5 blocks have an oiling port in the valley that is specifically for a turbo, and is simply plugged in non-turbo applications.

Thanks dieselboy and wthif,
That helps me a lot. I have the oil and trans cooler in front of the condenser and that is infront of the rad. SO THAT IS GREAT NEWS--I DO NOT HAVE TO MOVE THEM! So you say why the post? Just thought while I am moving fuel lines, trans lines and exhaust may as well move something else.
Thanks again,
Don Cannon

Hello all,
What if I do not have the $$ for the Injection pump and the Injectors. Do you think it will run ok with the old ones for now? If you feel strongly about it I could use plastic, but you all know how that is.
Thanks everyone for all your help,
Don
