Turbo questions

[orion_134]

I am fabbing a 96 Van turbo into my Mustang and have some questions. Will a -4 oil supply line and a -8 return be adequate? Also, is there a difference in exhaust outlet size between the .84 and the 1.10 exhaust A/R housings? Lastly, does anyone know where I can get a .84 A/R van exhaust housing?
Thanks,
Jesse

First of all

Thank you for your service, though it might from some, it doesn't go unappreciated by my family and I.

The exhaust outlets are the same. I don't know for sure about the line size, I know in the factory setup on my truck the feed is about 1\2" or a little less, and the return port is 5/8" I would guess, been a while since I had it off. Are you gonna cnc a manifold to fit the center section? I don't know how you are planning on plumbing it to the factory center section.

Wether van or truck the turbine housing are the same I think, the vans just didn't use the ebpv, but that is not part of the turbine housing, it is in the turbine outlet, so change the housing, use your outlet you have.

You can get the .84 a/r, or the 1.0 a/r housing from gts motorsports
But good luck getting ahold of him.

Thanks for the support, it's good to know there's some out there who stand behind us. I will be cutting the pedestal off about 1.5-2" away from the mounting flange and tapping in AN fittings. So both housings use the same v-band and bolt up the same?

You're welcome.
My brother was army airbourne.
Lots of my Dad's genreration was in the military.
My boss at work was a Marine.
One of the biggest regrets in my life is letting my Dad talk me out of joining, before I had a family at home and such.

I see, was wondering how to plumb it.
Yes the housing's will bolt up and all the same. The v-band actually clamps onto the exhast mounting flange which is part of the extension housing, not the same as the turbine housing, it bolts onto the turbine housing. The only difference between em is the amount of exhaust gases that are allowed to go around the turbine, instead of through it, smaller housing, more exhaust forced through it. I can't recommend a size though, I don't know a whole lot about gas applications for turbo.

AWESOME!
first a warning- make sure that you mount the turbo high enough so the oil will drain down into the pan, or you will need to install a pump and check valve to evacuate the return oil. this is a common problem when putting a turbo on a previously N/A'd car.

the -4 might be ok, but if you arent married to it i would go with -6 to be safe, and dont use 90* fittings, use sweeps. a 90* fitting is equivelant to adding an extra 7' of line.

as far as the exhaust housing goes:
1- what engine is it going on, what displacement is it, and how fast do you intend on turning it?
2- how much boost pressure do you plan on running?
3- are you building the car for drag racing, or street racing?

 

[orion_134]

Yeah, researched enough to know about the plumbing.
1) 306 head/cam/intake car turned to 6k
2) 18
3) drag racing, street reliable
The 1.1 exhaust housing won't give me any useable boost until 3k+ so it's either find an .84 housing, block off one side of the divided T4 flange (but will be giving the wastegate a work out with a .55 a/r) or don't use the turbo

is this in a fox body?
i want pics if you go through with it!
18 is a big number.....should make some serious power!
pm 79broncoidi...im not sure if he is looking to sell it or not but he has an ats turbo housing (wastegated) that he might want to get rid of because he is looking to go to the 1.0 housing.

 

[orion_134]

Unfortunately, I don't know what it would take to make a wastegated housing work non-wastgated. Yes, this is going in a Fox.

the waste gate is adjustable, i would recommend it in your application to prevent over boosting, leaning out and popping the precious 306. its just like adjusting the vacuum secondaries on a holley. you can essentially turn the tension up so high that the gate would never open if you prefer, but if you are shooting for 18, i would set it to open and maintain 18 psi. don't confuse the waste gate with the EBPV, the big ugly flap that covers the outlet.
