7.3 VGT Turbo conversion.

Hey guys, i was wondering how complex it is to install a VGT turbo either the 14 Vane 6.0 03 turbo or the HE351VE out of the 6.7 cummins

Theres a guy who did it to a 7.3 IDI and man it sounds likea jet.

Ive been wanting a 6.0 but i only want that jet turbine sound.

i know it can be done to the 7.3 powerstroke im just wondering if anyone has done it and has a write up!

If you do a search you should come up with a couple threads about putting a 6.0 VGT turbo on a 7.3, IIRC, it is somewhat complicated, involving complicated wiring.

he is the issue gabe... the 6.0 turbos and 6.7 turbos dont flow air in the right areas for a 7.3....the compressor maps are all worng and run out of air up top. the 6.7 turbo is a better choice as u can use a modded wategate to control the slide on the turbo so as it builds boost, it opens up the vains. the 6.0 turbo will require a complex circuit to controll the nozzels in a 6.0 turbo.

other options are VNTs, or VGT's out of big rigs like a detroit, CAT, or freightliner. they will require a T-4 or T-6 mount most of them operate on boost also. turbos like a gta4294s, or a Schwitzer s410t.

the other good thing about the cummins 6.7 turbo is it has an option for a turbo brake which is just supplying 12v to one wire! my best guess is find someone who modds the HE351VE to flow more and be more applicable for the 7.3 application.

Yeah id rather use the 6.7 turbo. It doesn't.look hard . I'll probably just keep factory turbo on there and then use the 6.7 turbo for compound set up Running the 6.7 turbo for the passenger side manifold reversed withl a Tv flange. so the factory turbo would power the secondary turbo.
Is the HE351vef350 holset controled mechanically or electronically. Cuz I've seen some guys do it with a spring

why would u use a larger turbo to spool a smaller turbo that runs out of air up top????

the point of compounding is to use a small turbo that spools quickly to spool a larger turbo that takes a long time to spool under normal drive pressures... so now it has boosted drive pressues

The Holset is electronically controlled as well, but there is conversion kits for sale or for DIY.

Look on CompD and search for HE351VE for some DIY boost referenced actuators.
