To even CONSIDER building your own turbo setup, you should CAREFULLY read a book or two on the subject.

My first recommendation is Maximum Boost by Corky Bell.

The second is Forced Induction Performance Tuning A Practical Guide to Supercharging and Turbocharging by A. Graham Bell

Amazon even sells them as a pair for $52.

While you're at it, you might buy a book or two on engines, fuel injection, and tuning in general as well.

Don't even consider bolting or welding a single thing on your car without understanding what it is that you are doing.

Take mine and many others advice. There is NO such thing as building a turbo on a budget...Atleast to build it right. TRUST ME! Theres alot more to it than just buying a used turbo, some pipes and an intercooler. Lest do a little math here...

Used Turbo $100-$150
Wastegate $250 (external)
good FMIC from ebay $400
Oil lines $100 (braided) feed and return.
Custom maniflod $350-$500
Down pipe $100 $200 with a cat.
piping and couplers $200-$300
Boost and A/F guages $100-$150
engine management $lots and lots...

BOV $200 (greddy)
unexpected mishaps $250

beating a mustang or Z28 with a 4cyl....priceless


Theres alot of components to building your own setup. I have been there and done that. Just a few things to think about. Good luck!

If he had the skills, it wouldn't be THAT expensive. One member on here had a junkyard setup for under $1000.

On these low output applications, an external wastegate isn't needed and a custom manifold isn't needed.. You can just build an adapter flange for the stock manifold to go SUPER-budget. It'll flow plenty.

FMICs can be found for $50-$75. Piping could be had for $100-$200 for everything if he had decent TIG welding skills. I bought a 1G DSM BOV for $5 from a yunkyard, and it is plenty good for this application.

IF he had the skills and knowledge, it could be done.

I agree though, the engine management would be an issue. About the ONLY super cheap form of adding fuel is a fifth injector.. Which is kind of a lame bandaid for a Focus, but has worked in the past for a couple people.

Overall zx3focusguy is right on the money.. it needs to be done correctly. Incomplete or poorly done setups = engine go boom.

Yeah sure, you could build a budget for less that $1000 but why build a half ass kit thats destined to problems? It just doesn't make sense to me but hey thats just IMO. My $2000-$2500 setup is with 110% all my own labor. But IMO, it's done pretty decent, really no corners cut. But like I said, this is just all IMO.

I agree with you entirely, I'm just saying that $1000 doesn't necessarily make it half-assed.

I turbo'd my Escort for $1000, It might not have a cool aftermarket FMIC or BOV, but it's reliable.
I used a lot of stock peices, like the IC, BOV, a used FMU, New injectors set of 8 split with some one else, A-FPR 50 bucks...I jusk keep the boost low nuff and octane high nuff to get by with stock ignition (colder plugs) and timing.
It did help that turbo's were stock on escorts in 84-85, thats were the mani/turbo and down pipe is from, $400.
Gauges, another $100.

mine has cost me up at about 3000+ ofcourse im running haltech e6k which was a big chunk of it, and rebuilt the motor, so i guess you get what you pay for is all i have to say...

Even if you use a turbo w/ an internal wastegate, you can still hook a manual boost controller and still crank up boost pretty high, (like around 14 psi, which too much for the stock motor anyway They do with the turbos in the ecliplse.), just the same way as you can with a turbocharged car from fact. put a boost controller on it and turn it up, Please correct if I am wrong, but which is better internal or external, internal would be easier, and I think you can still turn up the boost on them. So what are the advantages of an external, am I wrong?

The only real advantage of an external wastegate is use in high output racing engines. For streetable cars with reletively low output, the quality of flow isn't a big enough issue to bother.. Internal is so much more compact. If you want a "technically" perfect setup, then external is proper.. Of course, if you also wanted that sort of detail, then you'd have a divorced wastegate exhaust pipe.

With that said, what is consider low output, and what do you mean by low output, are we talking horsepower, or are we talking the amount of PSIs that are being produced by the turbo.
If I understand correctly, there is no nead for an external wastegate unless your going for a 300 hp focus, maybe not even needed for that.
depending on the aplication,
I know these are 2 completely diff. cars and nothing alike, but for example you can turn up the boost on an eclipse to around 16 PSI, and running around 280hp or even more. Not taking in the factor the motor will blow with out some internals.
I am just saying a turbo with an internal wastegate will handle up to 300hp or more depending on the turbo.
Am I right, or am I way off.

The only reason why I am asking, I to will be building my own turbo kit, and I am trying to think if I should just set it up for the external now or if the internal will do me just fine.
Eventually I want to be at 300 whp, hopefully little over 200 whp with just the turbo, but we will see.

Even if you do get a junkyard turbo, always rebuild it. T3 rebuild kits cost around $65 on ebay, and a good deal ona turbo itself is $70 (I got all 3 of mine for $15
) I have to piece a turbo setup together no matter what cause I drive a Saturn, it's extremely possible to do for under $1k if you play it smart and plan ahead of time.

maybe so, but that can't include some kind of fuel management.
