Hey i was wonderin if anyone has ever tried the exhaust headers made by Diesel Innovations for our 7.3 Powerstroke. Would somthin like this be worth the money. Just curious as im sure others are. Also i have a 01 powerstroke and also am curious if the Garret ball bearing turbo would be a good way to go for a turbo upgrade or is that H2E a better choice. Thanks in advance, Chase from Alaska

 

I had heard that those headers are only necessary if you are making over 500 HP. Someone can correct me but I thought that is what I had heard.

 

Wow those things are pretty.

 

The DI headers sure look cool, but I don't know how beneficial they are.

I ran them on my truck but didn't do before and after dyno runs or anything, certainly didn't notice a change in EGTs or spool-up or anything, actually.

And now the pair's on the work bench all cut up. Ever try to modify cast iron manifolds?

And on the turbo, I won't try to start a pissing contest here but (imho) the Garrett is blah. It works well as a stock replacement and compliments little injectors well. Seen alot of 400 hp 7.3s running around with good sticks and the 38r.

The H2E isn't comparable to the 38r. It's a mans turbo!
You don't want to slap one of these on a stocker. Windowed blocks by bent PMRs and blown head gaskets will come courtesy of an H2E and it takes big sticks to spool. Seen alot of 7.3s in the 500-600 hp range with the H2E. Would be my choice between the two.


What are you after?

if you think the h2e is bad take a look at swamps sledgehammer, its a beast

 

There, my friends, is the real question that must be answered truthfully by each individual. Will you really enter sledpulls? How competitive do you want to be in racing an 8000# truck? Or are you just after a big grin factor? And what really gets that for you? Once that is answered truthfully (by yourself AND your checkbook) your path is laid out. Finding the right combination of parts to attain the goal at the end of that path is the money part; not letting your ego derail you is the hard part.

 

So if I'm looking at modest power gains, a more reliable turbo, complimented with slightly larger injectors, the Garrett BB would be a good choice, no?? I just want a decent upgrade to the the stocker, without having to replace rods or put in head studs...

Oh, and sorry for the hijack!!

 

i have heard the TN BB was the best bang for the buck for up to 450 HP..

 

That's what I'm looking for, Ron. Is the TN cheaper than the Garrett BB?? Never looked, and I'm way off (hopefully -- knocking on wood) of needing a turbo.

 

Well the headers are for basically someone who has everything done to his engine and is looking for the last thing. Most people that have them are at that point in their engine build up, or they like the sound. I love the sound, it makes them sound halfway between a stock 7.3 and a straight piped 6.0, with the raspy crackly v-8 rumble.

 

the TN is a couple hundred more.. http://www.shop.blackwidowdiesel.com...&categoryId=62

not sur but i think i see 50 lb of boost here. http://video.FTEs diesel forums.com/...7601627944.htm

 

No, thats between the needles of 20 and 25 pounds.

 

Kris is the TN better then the garrett??? or is it about the same ???

 

Like it was mentioned, the DI headers are for higher HP engines. Most people won't notice the difference putting them on a mildly modified truck.

The TN BB and the Garrett BB are supposed to be very close performance wise. The Garrett can have surge issues under certain conditions. I have the Garrett and mine doesn't surge, but I have ridden in a truck that did have surge with the same turbo. However, the compressor housing on my Garrett is ported, so that may have something to do with why mine won't surge. The TN won't surge, but the BB version is a new turbo and there have been some "growing pains" with it. Those issues are fixed now, and the owner of Turbonetics even came on some forums and made a public apology for manufacturing defects found. You don't see that often.

The H2E can be run with stock injectors, but you need really good tuning and fuel control to make it work. Otherwise it will be laggy. It does handle bigger injectors and can be modified later to handle some pretty big sticks.

You can only make as much boost as your fueling allows. With stock injectors, you can't make enough boost with any turbo to cause you to need head studs or break rods. Once you upgrade injectors, then it's time to look at your power gains. Going above 400 hp usually means you're reaching 40+ lbs of boost. That 40 lbs mark is when you start needing head studs.

 

I'm assuming those turbos support boost in the 30-40 psi range, right? Right now what I'm looking at is maxing out the PMRs (safely). So bigger sticks & the eventual turbo upgrade are already planned. It's just so far out there for me that I haven't looked at turbo options yet -- just taking the opportunity to learn (hijack) from this thread...
