Already got a pro turbo kit and am gonna run it on a stock 351w for now. I want to get a single t66 ball bearing turbo and eventually get a second one in two years and adapt my single turbo kit into a compound setup. At that point I'll have a dart iron eagle block and a forged rotating assembly. Until than I just want a fast spooling turbo that I can compound with a identical second turbo to make 1200hp+. I'll probably only want 4-450hp for now cause i think thats all the stock 351w block/rotating assembly can handle.

I think the turbonetics t66 ball bearing turbo looks like a good choice for a future compound setup. First I was wondering if I should get the p or s trim style turbine wheel. And should I get the turbine wheel in the 62, 65, or 68mm diameter. Also which ar housing should I go with. My options are .58, .69, .70, .81, .96 and should I get the tangential housing? I'm just not sure what the best setup is to work for now but also work with a second turbo when I compound it with another identical turbo to make 1200hp+.

I should get the water cooled version too right? Also which wastegate would be the best choice. I need to be able to restrict the boost output to keep her under 450 so the stock 351 dosen't blow up. I'll be using a cheap manual wastegate controller. It'll have a water cooled aftercooler with a meziere pump. I'll have 20gallon tank in the trunk to hold the ice and coolant. This is going in a 84 mustang lx hatchback and emissions is no concern cause the car no longer has to pass emission standards in my area.

Do I have to still use antifreeze for the aftercooler coolant if I use this additive and if so at what ratio to the water?

On one last note what psi should I run to keep her at 450 and under. 351w was just rebuilt bored .030 over with dished hyp. aluminum pistons. GT40p heads for now and a edlebrock jr. victor converted to efi. Thanks guys any help would be greatly appreciated

ok first off what is the car gonna b used for, mostly street and some strip? mostly strip and some street?
Did you mean a twin setup or compound, small difference?
As far as your exhaust housing a .81 is good! pulls like a freight train mid to higher rpm. I see full boost around 4500 i think.
If you want to go with a water cooled version thats up to you. As far as wastegates contact a turbonetics dealer b4 hand and they will be able to help you on what they recommend. I think you will be fine with a 44mm wastegate.
Its always good to look at the compressor maps and see if that turbo is right for your setup, or future setup

a T66 is gone to be just to small for a 351. I know you said you are gone to run a future compound set up but why not just do a bigger single or maybe twins compounds are really not needed in this case. but to each his own.

Its going in a 84 lx and it'll mostly be a street demon and like I said before emissions standards are of no concern cause I no longer need to meet them. I think I'll get something like a tial 44mm wastegate too. Do you see a lot of lag with the .81 housing in the 1-3000 range. I mean if thats what you think a good ratio is I trust you I can always switch the housing out. I was talking about compound turbocharging where one turbo is fed off the downpipe of the other. The reason I want to use this method is that I can locate the future second turbo where the smog pump used to be and utilize the my exisiting exhaust piping kit. I already have a pro turbo kit meant for mounting one turbo on the passenger side and then as soon as I get my dart block and forged rotating assembly I can add a second turbo. Thanks for the help man

So the t66 would be too small for a stock 351w? I have the turbo kit but I haven't bought the turbo yet. Do you think the t70 would be a good match? I'll take whatever suggestions you have to give me. The reason I want to run a compound setup is that I already have a pro turbo kit meant for a single turbo. I could easily weld a t4 flange onto the downpipe of the first turbo and run twin turbos when I get a engine that can handle more the 450hp. I need to keep my power levels below 450 for now to be safe on my stock rebuilt 351w until the year after next when I get my dart iron eagle.

Dosen't a compound setup basically do the same thing as a twin setup? I mean I really don't want to scrap my existing $1500 turbo hot parts kit so that's the reason behind the compound idea. I figure when I do this in a couple years that a compound setup would probably create less lag than a big t91-98 thumper. Plus I'd just have to buy a extra t70($1500) instead of a almost $4000 thumper unit and I'd make just as much if not more power with two t70s vs. a t91-98.

And to reinterate I already own a ptk single turbo kit. That is my reasoning behind the compound idea so I can just modify my existing kit since the kit was $1500 and I'm not just gonna sell it or toss it out. I don't think I can run a big thumper for now on the stock 351w and stay under 450hp. If I could I'd probably have a crap load of lag and that wouldn't be good for street driven which this car will be doing a lot of.

I got a quarterhorse tuner to tune the sn95 t4m0 pcm I'm using so I can switch settings on it to make it street friendly even when I get the dart engine in two years. I figure I can install a second bank of fuel injectors a little higher on the jr. victors runners when that happens. I could stick 96lb injectors in the secondary bank and use a injector driver to power them. Got the idea from someone on turbo forums who said that with this method the second bank can be switched on and off so that the car can be driven on the street with low boost without running too rich. Cause if you just stick 150lbers they'd always be putting out a crap load of fuel and it would'nt be street friendly.

[ryan7662]

Would a t76 be too big? I'll be using a 3psi spring in my my wastegate to keep my boost levels low so I don't go higher than 450hp. I'll have a manual wastegate controller so I can turn it up a little but I'll have to be careful cause I need the stock 351w to last until I can get the dart block in two years. I'd rather save my money for the dart block and its stroker kit than spend it trying to beef up a stock 351w. By the way it'll be a 383 or 408 stroker when I get the dart iron eagle so I'm thinking two t76's might be a good match? Let me know if I'm right in thinking this or if you guys have a better idea on which size for my compound setup. Thanks again for the input and help I really do appreciate it

[ryan7662]

And I know it sounds like a lot of power for the street but if I can do it......why not? I'm sure I'll take it to the track but I'll also be driving on the street most of the time. With a quarterhorse tuner, secondary fuel injectors, and a good wastegate I should have the ability to go from 500-1300hp with a few knobs here and a couple switchs there should I not?

[ryan7662]

And yes I've pretty much decided to go with aftercooling since ambient air temps down here are routinely in the 100's for a big chunk of the year and this will be a street car. I'll maybe add a snow methanol injection kit when I compound turbo it too. I'm getting one of those 1000hp ebay aftercoolers that most people I talk too say are actually bad ass and high quality. They can be had for around 80 bucks. Heres a link to what I'm talking about
Liquid Water to Air Intercooler 3" HUGE Drag 1000HP:eBay Motors (item 230373922273 end time Sep-09-09 21:03:25 PDT)
I'll have a big 15-20gallon tank in the trunk to hold my coolant as well as a crap load of ice. The 20gpm meziere pump should easily circulate the coolant back and forth to the front of the car. I'll put a single core radiator angled in the front of the custom bumper to act as the primary heat exchanger after the aftercooler. I'll probably add a couple small trans coolers under the car to further cool the coolant on its way back to the resivoir in the trunk. I'll add a additive like this one along with a 10% antifreeze mixture.

Correct me if I'm wrong but I think I'd still need 10% antifreeze to keep the lines from freezing and to stop corrosion. If not or if I should run a different ratio please tell me. Thanks again for any help or input on this guys

what is your reasoning behind the compound turbo.twins and compound turbos are not the same. over just running a single that your setup for already? a 76mm on a 351 can make upwards of 1000 hp if built right and would spool very good. How fast do you want to go and what kind of HP are you looking to make is the questions you really need to look at. how much $$$$ you got to spend I will tell you this it wont stop at the block you got to have a fuel pump to feed this thing and a suspension to hold all the HP.

[ryan7662]

Oh yeah I know I'll need a pump to feed it. I'll add a second inline pump along with the walboro 255. I know about the suspension too. And I'll be getting a lenco st1200 and a 9inch rear end eventually and yes I will be building up the suspension. In the process of making and welding a 12 point roll cage and subframes for it. I'm shooting for a 1200hp goal when I get the dart block. I didn't know the t76 was good for a thousand. If thats the case than yeah I'll just ditch the compound idea and get a t76 or a t78 street turbo from turbonetics.

[ryan7662]

Transmission in a year
Engine in two years
Suspension and 9"rear end in three years
No house/apt payment and can put 45-$5500 away each year for parts so I should have it done in three years time.

And I'm doin all the installations and engine building myself so I only have to spend money on parts and not labor fees or anything. I've been building motors for years and only need the machine shop to do certain things like balancing the rotating assembly when I get my dart block. I can do anything that dosen't require bg expensive machies like lathes and balancing machines. I don't happen to have any fo those laying around in my garage.

[uedlose]

the GTS 76 mm will get you up near the 1000 HP flywheel not at the tire very easy any way, a PT88 will get you there and there are others as well. But when you are talking 1000 HP you are getting up there and a T6 flange turbo may need to be looked at more or twins. I also seen that turbonetics has a new 80mm turbo out also that may get the job done. the GT47-88 will get you there very easy and the spool time is great with one.
Also for a fuel pump you are gone to really need a lot more the a Walboro and a extra one in line. you are gone to need BIG fuel lines stock stuff is not gone to work our return is bigger then the stock feed on 5.0 cars. you should be looking at fuel pumps on the line of Weldon is what we got. Magnaflow, Pro Products to name a few Aeromotive there big pump. Sounds like it is gone to be a wild build keep reading and doing your homework

No dissrespect or anything dude but I got this I'm just wondering which ar housing to use for now on the stock 351w for quick spooling under 450hp. I mean correct me if I'm wrong but heres what I had planned for the suspension

granatelli tubular kit with coil over conversion $600 in jegs maybe cheaper on ebay or elsewhere
good set of struts probably around $200
already upgraded to cobra brakes and rotors and it has sn95 spindles
upgraded rear upper and lower control arms $300
9"ford center section around $300
Around $400 for a differential for the 9"
9"housing with tubes installed $300
Axle braces $70
$200 for the axles
Pinion support $100
ring and pinion $300

8 second street mustang............priceless

Yeah I ain't using the stock 5/16 either I was going to use 3/8 I found in summit. Do you know where I can order 1/2 fuel line cause I can't find and I don't want to buy a entire kit from somone I'd rather build it myself. I really do appreciate you bearing with me dude and tryin to help me out. How much would the turbonetics t78 be good for? I'm looking at it cause I'd like to keep the turbocharger cost around $1500 and thats how much a t78 is. Thanks a lot for your help uedlose
