trying to put together a twin turbo setup...

[Stephen87]

on paper for an engine swap I am going to do

here is what I have so far

manifold $800
what do y'all think of these(I am not exactly a professional at fabricating stuff So I want to go as simple as possible)

manifold

they are also on ebay from the same company for 700

turbo 100-300ish for 1 off of ebay
brand-Garrett????/preferably something water cooled(so I wont have to deal the that coking problem I keep reading about.)
t3 or t4 inlets
I am not sure on size I need to read a little more into that but probably something small(like something from a 1.8-2.2l engine) and then a medium sized one not sure what size

I also know I need tubing but I have no idea where to get it at and have no idea of the cost

inter-cooler - $80
probably just this one or something like it for a twin turbo get up

INTERCOOLER

waste-gate - about $80
unless you know something better

WASTEGATE

don't know enough about blow off valves yet

what else would I need to get to get this project going

the engine will be a 5.4 with all forged internals including crank shaft(stock block also stock heads)

the transmission is, hopefully it fits, a zf transmission from a 02ish f250 and the rear end is from a 5.4

also will I be able to use the stock throttle body and elbow also would it help to upgrade to the 75mm one from bbk and port the elbow

any constructive criticism as to what I have put together so far would be appreciated

Also some more specific vehicle info

I am going to do the 5.4 swap into my f150 and while I am doing the swap I am going to build the 5.4l engine with a forged rotating kit from a website called modmax
the transmission is a zf5/6 from a 2000 f250
my main purpose with this vehicle is to do towing and some off roading so putting the turbos under the truck is pretty much out of the question

if you need more info ask and I will try my best to fill in the blanks

Dude you get what you pay for. Those turbos off ebay are junk for the most part and a water cooled turbo is going to cost you a bit more than 300. As far as manifolds. You put $800 there? You can get some from Magic Bus..www.turbochargedinnovation.com for $750 coated and 600 non coated. I would take a look at those first. And yes, use the search button it is more than helpful.

[Stephen87]

Ok so I like the way the headers from turbochargedinovation.com look like I would rather put my money there but will they fit the 5.4l engine, i will probably just email them, and since y'all are telling me the ebay turbos are crap then I probably better try and find some from a reputable dealer so as to save my self the pains of them falling apart on me

edit: how hard would it be to have the turbos oil cooled and then later on when I have the money convert the system to be water cooled, also how do y'all feel about junkyard turbos, I was also thinking as a money saver I could get two turbos from an older ford turbo'd car(listed in the DIY section) and use those till I have the money to get two good superchargers

Your not going to converter a non water cooled turbo to a water cooled turbo, at that point you would just buy a new turbo.
Don't worry about getting a water cooled turbo most people on this board don't use water cooled.
I'm no turbo sizing expert here but from the sound of what you want with this thing is to be a torque monster with some good pull up top too. I think a single turbo would work fine for you, perhaps a single Master Power T70 would get the job done. Its cheap and reliable. I don't know your power goals but that turbo on a 5.4 would definitely boost quickly. But see what the other members on this board have to say about it before you run out and buy it off my recommendation. Also if your looking for more hp than the master power t70 will support look into the borg warner s-series turbos they seem to be all the rage around here, I have no clue about pricing on those though. I wouldn't go to big on the turbo for offroading as your going to want that torque right away. If you go twins a set of factory turbos wouldn't be a bad idea but I wouldn't know where to start there.

sorry I did not word it correctly but what I meant was that if I buy an oil cooled turbo would it be hard to change it to a water cooled turbo later on but you answered it well enough to where I will just stick with a oil cooled one

[evobydarwin]

I agree with LowBoostin.  Why not try for a single turbo setup?  A MP70 is well proven and will be MUCH lighter on the wallet than buying two of everything (twins).

[Stephen87]

it might be worth it for both space(seeing as currently I am looking at moving my battery to the bed of the truck and moving the windshield fluid to the battery spot or just losing the fluid all together) and cost to do just one turbo plus how hard can it be to add a turbo later on if I feel I can benefit from twins

+1 .. especially if a single is something you might consider

I thought the same thing, but I am really getting disappointed as I thought it would be cheaper considering I had one. It is not much cheaper due to the fabrication involved in going to a twin turbo, so I am just going to go to a bigger single.

Good luck with whatever you choose to do.

[Stephen87]

thanks for the help you all have given me so far, I think that for now I am going to go with a single turbo probably from master power and then just use that until I feel I need a twin turbo(when I do I will get a smaller one that will spool up quicker than the larger one), also I guess I am going to have to start looking through the suppliers here for the intercooler and other needed parts.

[huffer]

use the search key and you'll find plenty of info on singles and twin setups...lots of builds on this forum with both,...
Just read, research and learn...
Good Luck!!!

Pretty hard actually.

Stick with one turbo... Although the 5.4 engine is rather big... the displacement is not that big.  I would go with something around 67-70mm range on the turbo.  T4 is fine and a .81 A/R turbine housing is PLENTY. 

[Stephen87]

Right now I am looking at this one and it gives me choices for a .68 ar and a .96 ar TANG <---whatever that means, so should a .68 ar be good enough or would the .96 give more torque quicker

[Supernatural Turbo]

"Tang" means tangential.  The turbine housing inlet is "tangential" to the wheel, instead of centered on the housing and requiring a sharp-turn of the flow.  Tangential is better in all cases except where it doesn't fit.

As for the A/R...if the motor is relatively stock, I recommend the .68 A/R.  I've seen that size turbine housing used on a pretty hot 347 mustang with an MPT70 and it ran pretty strong throughout the usable RPM range.  The .96 is bigger and would be less responsive.

[Stephen87]

Oh ok looks like I am going to go with the 68 ar thanks for the info

edit I also completly forgot about the fuel injectors, would 24#/hr be a good enough fuel injector

[LowBoostinT76]

Yeah for about 300hp
