I've been toying around with the idea of adding turbo charging my 73 4v cleveland that i will be putting into my 82' flareside. I was thinking abodut using a complet system out of a 88 thunderbird turbo coupe (intercooler and all), but i would take it apart and install the proper compressor/turbine wheels to get the right amount of boost. But would this be enough? Or should go with a twin set-up using the same turbos? If not does anyone know whereor what i could use, keep in mind i don't have a hole lot of money to buy a new one, but enough to make a good used setup work.

 

Use 2 turbocoupe turbos. Don't try it with only one!
If you want to run a single, look for a T4.

For more info, do a search at the forums on TurboMustangs

 

Thats what i thought, and i have already started browsing that sight.

 

i would do twin turbo if you have the time, $$ and knowlege. two small turbos will spool up faster, while still giving you your desired amount of boost.

 

Use one off of a dodge cummins they are desinged for 360 inches the inner cooler is a good idea and if you want twins run then in series(sp) and small one (T bird ) and big one (99.5 -02 PSD) that should make enough boost to blow the head gaskets out

 

If you want a single turbo, the turbo off the 7.3L Turbo-Diesel is just about right. Not that common in junkyards, but it can be found (took me six months).

Also, two turbos off any of the ford turbo-4 motors (mustang, thunderbird, etc) would be pretty close. So would two turbos off saabs, volvos, dodge daytonas, spirits, shadows, etc.

The "junkyard monkey" way of figuring out appropriate "junkard monkey" turbo quantity is like so:

(your engine displacement / donor car displacement) *
(your redline / donor car redline) = number of turbos.

Step 1:
(7.5L / 2.2L ) * (5000RPM / 7000 RPM) = turbo qty

Step 2:
3.41 * .714 = turbo qty

Step 3:
2.435 = turbo qty

Not a perfect calculation, but its ballpark enough that you can size junkyard turbos correctly. The math is easy enough that you can scribble it on the hood of the car next to it with a crayon

 

FREDERIC you should go over to the deiselstop.com and check out the for sale area it seem there on there all the time and cheap and not JUNK yard parts

 

Thanks frederic for that formula, now i have an idea on what to size and how many to look for.

 

Thank you for the tip! Much appreciated!

 

So if i use a turbo of a cummins 855 diseal (my dad upgrade the one on our versatile 875 tractor and now he kept the old one) whcih is approximatly 14.2L and using the formula above i get 1.066. Know from this formula, it says that this turbo is about right? Am i right?
