HIGH TECH TURBO - Dodge - Install
General Installation Tips:
With most turbos we provide 2 studs, 2 nuts and 2 bolts. These won't always be required.
On 99-06 installations however, your current turbo has two studs threaded into your existing turbine housing. Our HTB2/High Tech 71/HTSS Series turbos have no threads for these studs so we provide bolts to replace them. Some manifolds have 2 studs threaded in and some of these existing studs may be the wrong length for the new turbo flange so alternate studs and nuts or bolts are provided. Torque to 30 ft. lbs.
Remove and reuse your current oil inlet adapter fitting on our turbo.
If you ordered a downpipe and clamps from us, clamp up the turbo end and see where the exhaust end lines up with your current 4" exhaust pipe. On most exhaust systems you will only need to unclamp your old pipe and slip it into the new downpipe and clamp it up with the flat band clamp provided. On some systems that have previously been altered you might have to measure and cut the pipe in order to slide it into our downpipe for a perfect fit.
In rare circumstances we have seen aftermarket exhaust systems that won't extend all the way up to our downpipe. For these situations you'll need up to a 12" extension pipe.
On some applications the oil drain tube might rub against the boost pressure regulator rod. In this instance you will have to "dimple" the drain tube slightly for clearance.
03-06 Installation Tips:
Many installers find it easier to remove the entire manifold, install the turbo on manifold and reinstall the manifold / turbo combination.
Connect the oil drain tube to the turbo before installation. Often the flexible drain tube used on the 2004.5-2006 engine will aid installation on 03 and early 04 models.
With most turbos we provide 2 studs, 2 nuts and 2 bolts. For use where needed.
On auto trans trucks the transmission dipstick tube will interfere with the exhaust. You will have to unbolt and reposition this tube.
Dennis Cochran recently installed a Super Stock 62 turbo
on his 06 Dodge and has the following comments and suggestions:
I'm quite pleased with the results.
It seems that this is generally a "bolt on" item,
even if you have the pac brake installed. I have the jacobs brake
(you know, the one approved by Dodge/Cummins) and it required some grinding/filing/and bending in of the firewall slightly so that the exhaust brake could operate properly.
Right now I can hear the turbo whine which is not objectonable as well as the canister actuating when the brake is about to engage - again not a problem but a pain if descending a long grade when the brake is making/breaking continually.
Thanks Dennis!

Housing Clocking:
In rare circumstances you might find it advantageous to re-align your compressor housing (cold side) slightly in relation to your turbine housing (hot side) . or both housings in
relation to your oil drain. Re-clocking your housings won't void your warranty but might aid in the fitting of your turbocharger.
1. To change how your oil drain and oil inlet aligns, bolt the turbine housing to the
exhaust manifold. Then loosen the 4 bolts that clamp (with 2 clamps) the bearing housing tothe exhaust housing just enough to turn the housing. Position it where you'd like it and then retighten to 185 inch pounds of torque.
2. To adjust the compressor housing outlet position, simply loosen the 8 bolts (with 4 clamps) just enough to turn the housing. Position it where you'd like it and then retighten to 120 inch pounds of torque.
3. Be aware that you need to keep the oil drain as close to straight down as possible to prevent oil seal leakage.
Actuator (BPR) adjustment:
We set most of our actuators to 40 psi. There are several ways to adjust this pressure.
On our High Tech 71/HTSS Series turbos, all you have to do is turn the nut on our wastegate actuator arm to shorten it (more boost) or lengthen it (less boost). Two turns approximate a 1 lb. pressure change.
On our HTB2 series, use a pressure pump or compressed air with an adjustable regulator inline. Apply about 40 psi pressure to the diaphragm and remove the snap ring that holds the BPR rod to the wastegate lever. Shorten the rod to increase the pressure and lengthen it to decrease pressure opening. (Two turns approximate a 1 lb. pressure.) The wastegate will begin to relieve boost pressure at .015" movement from closed. Reinstall clip.
Some 2005 aftercooler tanks were plastic instead of metal so max boost on these units should be no more than 35 lbs. boost.
