The best way I can describe it Billy is its like trying to ride your bicycle up a hill in 10th gear. Kinda hard right?? , drop it down to 3rd gear now it's no problem.lol

Going to bring this back to the top guys.

I have a new question. I have a billet s366 currently, just towed across the country with it and was happy with the truck but not thrilled with the turbo. Was def under the turbo most of the way, barely registered boost on the flats. 366 was great and fun on the big end, but the truck is now a designated tow truck, and wont see WOT throttle anymore.

Anyways, Irate Diesel has the SXE for sale

This is a 'super core'. Can you order this turbo without an exhaust housing? And if so, are the exhuast housings the same between the previous 300 series BW and the new SXE line? Considering saving on the new and using my current exhaust housing vs dealing with selling the 366. Anyone know the deal with this?

Swaan · Apr 26, 2016

Yes . A super core is just a compleat turbo with out an exaust housing.
Order a 64.5 sxe supercore core with the 74/80 exaust turbine. This will go right into your exaust housing you have now. No need to even unbolt your turbine housing. Just re&re the super cores.
This will be way better then your 366 and put you right in the meat of the turbo when towing.
The 366 is a smokey hot dog below 2000 rpm , been there done that.

No joke! I want one of those sxe turbos some kind of bad, but my other projects keep getting in the way.

If I had the cash I would like to try a sxe366 and see how it compares to the s364.5.

Injectors are 175/80's from PIS.

Swaan · Apr 27, 2016

I've got the same injectors . I also had the same s366 as you so I feel your pain bro.
I'm assuming you have the .91 housing on your s366? If so then yes just buy that super core in that irate link you posted and it will drop right in to your exaust housing.
It will be night and day diffrence while towing.
Cooler EGTS and faster spool , more boost down low.
Perty much just way better drivabillity with more powwwwwaaaa everywhere.

Will he need tune revision or just rock out?

His truck is lifted and has the big tires. Its probably one of the nicest trucks out there. Period. Bar none. Not for an obs or super duty. Im talking all brands and all versions. Its a bamf truck. If you havent seen swaan search for his build thread. Its impressive. He even built his own coil, ala, etc setup.

Swaan · Apr 27, 2016

Well if this is the same Krause that had a 6.0 , I remember him from back then. He had a real nice truck then too.!!.

No need for tune revision. He will be building boost sooner so no need to pull fuel or anything.

Out of curiosity what gears are you running Krause and what trans and tire size??

TyCorr · Apr 27, 2016

I have two fiddy two hunnits but im reeeeeeally eyeballing that 364.5 sxe kit and mount from irate. Its a waste of that much fuel but this ***ker has to tow or its no use.

I wanna talk about gn hitches and airbags, where do you guys want me to start a thread? Towrig or general?

I knew you would eventually sucomb to the lure of the sxe turbos. Lol! I really wanted to see someone run that 364.5 with some 200% nozzle'd hybrids and you are just the man for the task.

Haha agreed!

mtsnowrunner · Apr 27, 2016

I run 250/100 and a BASB and couldn't be happier. Every injector builder I talked to recommended staying away from the 200's for DD and towing. I wonder why that is when so many people are running them? I thought 250/200 and a 467 would be badass. The Fleece billet 467 supposedly spools real quick and would maybe be a good low spooling setup?

I think my bigger tunes might over fuel my turbo, seems like the little bit smaller tune is just as fast and better down low for sure.

superpsd · Apr 28, 2016

200% nozzles need more precise tuning as in logging and going back and forth with a tuner and or live tuning or self tuning. They are streetable nozzles but correct tuning is critical. As for chargers I went with a S369sxe for my setup I am still waiting to install it.

mtsnowrunner · Apr 28, 2016

200's and the 369 should work great. I'm interested to hear how that works. Mine spools really low and egt's are low. I tow daily so that's important, and it hauls ass empty so I've been pretty happy. Good luck on getting yours done.

cjfarm111 · Apr 28, 2016

Please keep us posted superpsd. It's good to hear that people are giving positive feedback
On the sxe line

Thank you for the kind words on the truck. There are an awful lot of nice trucks out there, but this one still gets it done I guess.

Not the same Krause, have not touched a 6L yet that I can remember? Here is the build thread in case you fancy taking a read.

I am running 3.73 with 35inch tires (a metric equivalent), 18" rims.

So just to confirm; it sounds like the exhaust housings are interchangeable, that is great news! Are they identical? I dont wan to re-use exhuast housing if there was some small revision by BW for the SXE exhaust housing that is part of the efficiency increase.

Oh and yes it is a .91 housing currently

Swaan · Apr 28, 2016

Yes the exaust housings are the same and completely interchangeable. The only changed the turbine wheel itself in the sxe line but not the housing.As long as your turbine wheel size is the same they will interchange. I would stick with your .91 with the 74/80 turbine
