The S467 is also a great option, I have setups running those with stage 2's. They were replacing D66 turbos and from what information I have received back the turbos are spooling up about the same, just a touch slower and that is with the 1.10 housings. If running stage 2's with that setup, I would recommend head studs as well. You will be burning every bit of fuel that you can inject which makes a large difference. You will also see a dramatic drop in EGT's with that turbo as the flow is very high. But be ready for a fun install on the 467 with the race cover. It is a large unit. These are just some of our experiences, hope it helps a bit!

 

what is a S467 and what is atage 2???? all i have is a Stock truck with all stock 7.3 turbo in a 2 WD in a 1996 with 146000 miles?????

 

Welcome to FTE.

You have a long way to go before you worry about this stuff. This thread is a discussion on different size turbochargers and what injector combinations they would go well with. If your wanting to learn how you should start out modding your truck, feel free to start a new thread so we can address your truck and whatever questions you may have.

Jake, I didn't realize you were on FTE. lol That's the truth on fitting an S400 frame in an OBS.

This is the only pic I have of my firewall after modding to fit just the turbo. This has nothing to do with the mods we made to fit the downpipe. That cut is long enough to clearance the firewall for the entire turbo.

 

YES I do indeed have a long way to go BUT...After I get my transmission problem resolved and my ONE injector resolved cause everything else on my truck works GREAT including ICE COLD A/C.....
Then I do INDEED want ALL the power I can get out of my 2WD BUT still keep the DEPENDABILTY of it...

 

Devil-Dog:
Stage 2 injectors are a 160cc 80 or 100% nozzle A code injector. The S467 or S468 is referring to a turbo build by Borg Warner. Basically it is and S400 framed charger but has a 67.7mm compressor wheel so it gets called a 467. Same for all there turbos, the number is just an indicator of the compressor wheel. And there are many turbine wheel options as well for the Borg units.

Strokin'
Yea, I am around here! Don't get on the forums very much lately. And the OBS trucks are a treat! And you appreciate it a lot better after the install is done than you do during the install. Porta Power and Cut off wheel are good friends when installing down pipes. We typically pull the heat shield and address the fire wall and do the massaging and sealing back up and re install the heat shield so you can't tell anything has been done.

 

Travis I just couldnt bring my self to cut the firewall like that. I got pi$$ed off when I had to cut the seam off for my DP Lol

Jake with the s366 what size turbine housing and wheel would you run. I know that I could gain more from a s400 but im not out for a full race truck just good ole reliability and fun to drive

 

With the injectors in your signature you would be very happy. Had a customer with stage 2's running the 366 with a .91 housing and he would see about 1300* max egt's, and right at 40psi of boost which is where the 366 is at peak flow. The best spool will come from the .91 housing. The .88 will flow more than the .91 as it is a single entry housing; if towing and keeping rpm's above 1800rpm's for the majority of the time the .88 will be a better performing housing. The 366 lights off around 1700rpm's. It isn't a race turbo, it is best as a daily driver towing turbo. And can still be ran hard when needed. They will hold up very well as long as boost is kept under 50psi. That is where the end of the map is for the charger. It can be ran with 238's as well but will be towards the end of its map. I do have several running them with 238's with good luck, and putting down 500+. The 366 flows 1100cfm, so it moves a good amount of air.

 

Jake, at what point in your description above does the head studs need to be changed out?

Edit: If my D66 will flow 1050cfm and the S366 flows 1100cfm's, why are my EGT's so high with the D66 compared to the S366? Just a turbo dummy asking!

 

I typically recommend studs for anything running a stage 2 injector or larger. Some may disagree and some have good luck with pushing 40 plus psi out of factory head bolts. Depends on the level of risk you want to have. But with good factory gaskets and replacing the bolts with studs you shouldn't have anything to be overly concerned about. There is risk in doing anything over stock. Nothing is 100%. That is what I recommend any how.

 

I agree with that. Go ahead and do studs and springs if you have stage 2's and a good turbo. We've blown head gaskets on a truck with 160/80% stage 2's and a stock H2E with stock head bolts before. We also had valve to piston contact (valve float).

 

Soon as I get this and my trans done I'll be doing spring an DI push rods

 

I might wanna keep my worn out turbo. Ive been babying it so much that my last two tanks were 21-22mpg

 

Lets see now: studs, springs, pushrods, turbo, DP, T4, firewall massage, injectors rebuilt, hmmmmm, am I missing any thing?? Oh, sell my D66 & pedistal, bellow uppipes and 3 1/2 DP.

 

Glenn you could get around 1100 if you sold those things

 

That would be a good figure but I don't know how you came up with it!?
