Orly?

Yea it has 3 bearings, but I didn't know if that had a massive effect, but now I know though.
I'm sure there was a point in time where you didn't know everything. I didn't know it had three bearings. I don't know much about the Ford sixes but I don't think I'm an idiot.

Does everyone feel the same way about a turbo 200 or 250?

ok a few things here, first the 170 has FOUR main bearings not three. granted it isnt the best set up with an inline engine, but it does well.

now on to turboing the 170;

1: first build the short block to handle the power. this means forged pistons, forged rods, and yes the factory forged steel rods frm the early motors will do nicely after polishing and shot peening, and adding stronger rods bolts from ARP. also balance and polish the crank.

2: prepare the head for turbo use as well, larger valves, port the valve pockets, install stainless steel valves and hardened seats and dont forget the ARP head studs.

3: turbo selection is important here, as well as whether you choose a draw through or blow through set up. you fuel system choice will also come into play here, carb or EFI. each has its pros and cons, let me know if you want me to elaborate on them. my choice if i decide to turbo my falcon 170 would be a blow through efi or a raw through carb set up. as for teh turbo itself, select one from an engine of similar size and base power out put, say the turbo from a stock early SVO mustang or tbird turbo coupe as these turbos would be a close match for the 170.

4: control your boost pressure. keep it no higher than about 10psi max boost pressure. that will push you poweres levels up pretty good and give you a safety margin for a daily driver.

5: installing a turbo isnt as hard as some make it out to be on an inline six, the stock exhaust manifold with a "J" pipe does a nice job. check this link for lots of good information on turbocharging the ford inline six;

I wouldn't do it to a 170, the crankshaft isn't supported as well as the 200. With a 200, you could do it, although I'd keep the pressure low.

IF you keep the pressure low shouldn't be too much of a problem. Buy the Manual over at fordsix.com and read up on the tech archive they have. Sounds like it'd a be fun build!

There's a member on here who turbo'd his 6cyl on a budget, he was like 18-years-old when he did it and had pretty decent results.
This is true. He later did a very mild V8 swap on the same car and said that the V8 was just as fast and way more reliable than the turbo 6. If memory serves, it was cheaper too.

Back in the 1970's, in London Ontario, there was a fellow who put a honking turbo on his two tone (faded green and rust) Pinto. He blew off 383 Cuda's on the highway. Do-able? Sure. And about as controllable as a cannon shot. I never heard much of that car after just one summer, so that must say something.
As an addendum, when Porsche first put a turbo on their 911 in 1976 or so (now called the "Porsche Turbo"), it produced a sensational 0-60 time of around 5 seconds. Good for then, meh for now, but the Turbo was notorious for trigger like on/off action of the turbo, as waste gate management was in its infancy. You HAD to treat the car with respect or it would truly bite you.
Now if the OP finds a way to turbo his 170, not only will he have to find a way to still make it live more than 15 minutes, it will need proper thought and engineering to make the turbo step in gradually enough that it will still be decently drivable with even cylinder loads what with the log manifolding and so on.
Engineering a lot it looks like, I mean I am stuck at home. Maybe time to design something lol

While I'm not an expert, here's what I'm thinking...

- A boosted engine requires a special build. The pistons should be forged and the ring gaps should be specific for boost

- A turbo setup requires a LOT of fabrication. Such fabrication takes a lot of skill, like TIG welding, and many components. This add up very quickly to big dollars.

- If you did get a turbo working well in an I-6 Mustang, you'd have upgrade everything specific to the I-6 Mustang: 5 lugs, brakes, springs, diff, drive shaft, transmission...

- Unlike turbos of the past, modern turbos use oil from the engine. They spin up fast, make a lot of boost and they last a long time.

So, yeah. It would be really cool, but also very involved and very expensive. The pic Bart posted above is badass. But this is project for a very advanced builder with deep pockets and not something for a shade tree mechanic on a budget.

The Roadkill "Rotsun" is an example of someone bolting a turbo on a car and slapping everything together. Not surprisingly, it breaks constantly.
The rotsun was one of my inspirations, but of course they know much more than I do. It would require me to learn a lot more.

If I had a 6cyl Mustang, already having been a turbo guy, I would have built a 6cyl engine for boost, probably try to track down one of those aftermarket aluminum cylinder heads, and put a turbo on it. I'd run E85 and a 4150 style blow through carb.

Turbocharging design and controls have come light years since the Porsche 930 hit the streets. Just even in the last 15 years, building a good reliable turbo system is way easier today. Your biggest issue is going to be fueling with the log intake of the 170. It can be done, but you're going to need to keep the boost low. Almost to the point that it's not worth spending the cash and effort to gain 60-80hp.

If you're seriously considering it, check out The Turbo Forums There have been a few 170/200/250 build threads.

How about swapping in a supercharged 3.8 V6 from a Thunderbird Super Coupe? The 3.8 V6's are plentiful and dirt cheap. If you blow up a stock one, who cares, spend another $700 on a junkyard engine and do it again. You can usually find complete blower kits for under a grand.

I did not know what a Aussie 'Barra' engine was until this afternoon while watching Hotrod Garage while wrenching on the Mustang. Of course they tried to replicate it with GM "Holden" stuff as usual. I know they are easy and cheap to get in your neighborhood, but not here. Ever think about going into the export business?

Still learning, eventually I will get there.

Yea can you elaborate on Efi vs carb, I want to make a shopping list because some of this stuff I still want to learn but need to know what exactly I am dealing with so I can research it. i want to keep the boost on a safe level so I can get more power but at the same time have a fun daily driver so I will keep it kind of low. Thanks for all the info so far!

Where would be a great place to find more info cause I am open to all suggestions, thanks though!

At the same time though, I want something unique and there are barely any of these builds. It would be a great learning experience and if I don't like it, I part it out and get a v8 stroker. I have a 289 just need to put it in if i choose to.

You won't have great results turbocharging a single cylinder due to exhaust pulse issues but I've seen it done. One guy I know had a motorized bar stool with a turbocharged lawnmower engine. The turbo was more of a novelty than anything.

As you can see by most of these posts, this is the last place I'd ask about anything turbo related.
If i could find that dude it would be great to ask him these questions since he has done it before.
