Having never dealt with turbos, I was wondering if any body knows of a kit that would work with my 250ci with minor modifications.
"Close Enough" Turbo Kit?

From Australia, IMO you would be very lucky to find a "kit" for these old engines. Its going to be a DIY job.

..
unfortunately no turbo 'kit' available for Ford Small Block Six AFAIH, adapting an existing turbo setup to the six probably -' simplest' but many options open for the resourceful...
with my limited resources, 250 was adapted to the pre-fuel injection Buick/Olds/Pontiac carbureted' - Draw-Thru turbo setup from early 80's with a homemade adapter and some 'minor modifications'.
'got the idea from MacInnes turbo bible - "Turbochargers":
.
RW HP went from 88 RWHP to 191 @ 4K RPM !

STS makes rear mount turbo kits for 4.0 to 5.0 liter engines using a 59mm turbocharger.

That's really interesting. How does it oil/ return oil?
Seems lag would be relatively long.
Oil is still supplied by the engine but is returned with a pump.

Big horsepower and cheap for sure.
Then it won't be easy.

Fair enough. I don't mind physical difficulty as long as I have the know-how. But I don't.
I'm no turbo expert either. You can learn and figure it out, I'm sure. That's part of what prevents everything from being easy. I do all my own work except for machining, so I'm into the sweat equity too. I enjoy it.

Please do some reading on the subject before you do any thing, A Graham Bell has a good book, forced induction. https://www.amazon.com.au/Forced-Induction-Performance-Tuning-Graham/dp/1859606911
I would also add that a positive displacement blower will give a better all round feel on the street, the level of difficulty is slightly higher, but IMO performance is better. PS the kit shown above will require a LOT of work to get installed and running well.
I have a blown 200 crossflow down here in Australia, its great on the road, I did all the fit up myself, I did have the advantage of being in the Auto trade. I have had turbos and the big cam carby thing, blown is best.

If you want to do it cheap, go to a wrecker and find one a turbo from a similar size engine. Make a exhaust manifold outlet flange adapter to suit. run it blow through so you don't need a carbon seal.
Any opportunity to whip this pic out hey, lol.

Yeh I know, I cant help it. LOL I was never a showman, but this gives me a bit of an opportunity to throw it out there. Still, Im very happy with it, especialy with the low cost. "poser"
Yeah I "like" it every time- cause it is that sharp IMP.
I think its great and with an Aussie blower even better.
So the question needs to be asked.
How much power do you want to make?

The eternal l question. The answer, "speed costs money, how fast do you want to go?" i rekon i spent about $3000, and that was mostly for junk, and i did all the work for free. A light car, (around 1300kg) only needs about 200kW to be quite zippy on the road.

I want at least 1hp/ci. But preferably more.
