6.7 C/R to VE conversion OBSERVATIONS.

[AHineman]

What do you guys think about the Borg Warner part # 177283 63/68/.88 AR ?



#177281 66/73/.88 AR ?


#177275 66/73/.91 AR ?



All non wastegated T4 turbos. Not normally liked by the 1st gen crowd, but how many people have a VE powered 6.7?



Any of these could be ordered from Turbosupply for pretty cheap compared to a T3 wastegated job. Would any of these be ideal for the 6.7? I know you've got the added displacement, but you're still short on high rpm fueling. Any one have any thoughts?

I would not at all be afraid of that charger! The 73 wheel flows better than the 71 (like the 68 flows better than the 65)
The "14cm" housing is actually a .80 a .88 can't be THAT different
The 62, 64 and 66 aren't that big of jumps either
I'd say I'd run just fine
I love the 68 and 73 turbines and wouldn't ever consider buying a 300 without one of them having owned the 65&71

[Tacoclaw]

HX52's may be a decent charger, odd flange, but if you're looking at T4 anyways then it wouldn't be too bad. They're not too bad used, I think I got mine for $4-600.

[AHineman]

I'm just throwing some ideas out there for Mark. I think the whole vibe of this build is "budget hoss cat" . If that's what he's shooting for I figure those turbos could be had for $750 or less new (just a guess). Still a little chunk of money, but cheaper than most.

^^^^^^^^^^^^this one^^^^^^^^^^^^^^^ put that with a t4 exhaust manifold and it would be a pretty awesome deal, IMO.

Also, that turbo is CHEAP when comparing to the "normal" "Cummins" turbos.

T3 vs T4, but I think the T4 would be ok with the 6.7. IDK.

I'm looking for a machine shop I can trust to listen to what I need for basic machine work.
I want to freshen the surface the head and the deck of the block, plus swap cam and crank gears around,

There's a race engine builder 2 towns west that I used to trust with my V-8 Mopar block and head work, but I don't know if he will touch diesel stuff and he doesn't do crank work.

FYI, I got to looking and I have a smaller set of injectors that might make a smaller turbo more practical.
I believe they are a "Mach" injector, though they are an 8 holer, they are small holes.

Don't puss out on us now.


I've never heard anything good about 8 hole injectors and VEs....

but since you've got them, why not try both sets and see what works.

[RCCUMMINS89]

I've heard of a few guys (guys that know more than any of us even wish to know) that have ran those t4 turbos a long with an "actual t4 manifold" that say they work great, even on a ve pump.

Have made ridiculous numbers too. (brad ponci is one).

Also, those turbos work great on common rail trucks.........I honestly can't see it not working well with a 6.7 ve truck.

[Mark Nixon]

You guys are seriously pushing this.
I appreciate that.
I have 2 trucks I could stick this in, but I am a LONG way off.
I still need to get the block face drilled, but Michael Miller has graciously offered the use of a sweet drilling set-up that should work awesome to achieve this.

Mark.

I run a 64/68/14 on a stockish ve with 7/10 sticks it spools fast and I have out grown it I'm stepping up to a s400 that's a 72/74.90 in the next few weeks
There is no way I'd run less than a 73 turbine on a 6.7 of any sort IMHO

[Kasper Cummins]

I run a 66/73/1.00ar t4 and it's slow to spool. That's with a mild pump tuning and 5x14s. It can be driven smoke free pushing 30+ psi but would suck for towing. A 62 would be my pick for a 6.7 VE. Also the 66 is an ebay junker, so far it has 2000miles and still like new, not bad for $400.

[SuperiorRam]

Ok I wouldnt run that combo on a little 12er Unless I'm spraying the living hell out of it ALL the time

The 6.7 is a hole nother animal period ve pump or twin cp3 I've OWNED and built one talked to others that built them and what they did. There is a reason the he351cw opens up to what 32 cm

Not that it matters anyway mark apparently can't log on here anymore, my GUESS is cause he speeks his mind. A damn shame another guy who actually knows his stuff gone. Another scenario where the journeyman can't teach the apprentice. Bad call

[Tacoclaw]

He's not gone forever, don't cry too hard.
Maybe if his spoken mind was a little more funny and less offensive and vague then he wouldn't have these little vacation problems. Anyone with a brain knows they're going to get in trouble starting a huh? like that in an innocent thread.


I do find it funny that this thread has gotten this active when Mark's not here too see it.



Also, I run a 67/71/16 HX52 on my truck and even with my mods it's borderline for DD duties, no way I would expect the thing to actually tow without keeping it really wound up.

[oldestof11]

Mark, the cubes on a 6.7 can spool, as a single mind you, what most are running for sn.atmosphere turbo on compound setups. I would not do less than a HX50 series turbo.
