"Slant6" (slant-6)

Ill write up more of my crazy ideas later (tomorrow). But can I keep my perfectly functional single barrel with about 4 pounds of boost? Im not looking for crazy power. The engine originally made 120 something and if I could get 160 out of her that'd be perfect. I just need a little more power for safety.

How many barrels is your carb?

Depends on the barrel size / diameter and (of course) very careful carb tuning from what I've seen. It can be pain in the ass to get a blow-through turbo to work half of the time on a 4-barrel with a plenum, much less a single barrel.
Also, 4lbs of boost is not going to generate 33% more power though, unless you're at really high elevations (in which case the "Effective" boost over atmosphere is higher). Especially if it's producing it lower in the rev range or if carb tuning isn't accurate. In ideal conditions, it's possible I suppose, but the amount of carefully selected parts and precision in matching the carb to the cam and the turbo to get it to all work together to get enough peak power to hit 160 with only 4psi is stretching it, but this is just my thoughts on it. At the end of the day, it will still be a sputtering and disgruntled intake.
For less than a turbo, you can maybe try different rear end gears and smaller wheels to get more torque to the road, plus maybe multiple barrel carbs (...do side-draft 2 barrel carbs work on the slant 6? Because maybe there's a motorcycle carb conversion kit out there so you can run 4 or 6 smaller barrels instead of 1 large one for greater efficiency and power) and/or a more aggressive cam profile.

Single? I'm pretty sure. Stock one on a 225 slant 6.

I'd start there, myself, 2 or 4 barrel will wake it up pretty well, esp. the 4.

Safety, huh? I'd just carb it. With something that old I would think it's easier to get a reliable carb setup on it.

I'm no expert on the slant 6 or turbocharging but you might want to start here http://www.squidoo.com/slantsix to get some ideas that might be easier ways to make more power. It seems to me changing from a one barrel to a two barrel, and the respective intake manifolds would be a good start whether you choose to go forward with the turbo or not.

Im just trying to do a cheap turbo conversion. I plan on taking a J pipe from the end of the stock exhaust manifold into the turbo then intercooler then through the stock carb. I don't want to spend the $270 0n a new intake and about $200 on a used 4 barrel carb. I plan on doing it eventually and I could always adapt the turbo to go on the 4.
Im thinking turbo off an old volvo, then cheap intercooler ( http://raleigh.craigslist.org/pts/4388029197… ) and getting metal work fabricated by a local exhaust shop.
I just really want turbo.

My answer with conjecture is that it probably won't work.
Warning, technical comment ahead: carburetors operate off of vacuum. People may have told you this already but it's localized vacuum within the carburetor and a lot of very complex aero that makes them work. It's honestly a fucking wonder that they were established as the norm and standard before fuel injection. Anyway, what will happen if you try to blow through a non-blow through carb is you'll end up pushing fuel and air back into the float bowls since the bowls are non-pressurized and your air stream is. Blow through carbs normalize the pressure between the bowls and the air stream (throttled part) so that the carburetor operates the same way it would if it were not turbocharged.
At 4 psi you could try a suck through but that may exceed the cfm of the carb.

Ah, that's pretty clever. I would imagine a setup like that would cost a lot less
I'd still be very careful, and don't expect much unless you can figure out how to get it all to work in sync ( http://www.fusca.net/wp-content/upl… check this out if you haven't already) because it's VERY complicated. I won't pretend to know how to do it, but I do know that it's never as easy as it seems.

I know you might want turbo, but why go with the added mechanical complexity if you can get similar (or better!) power out of a much more simple fix?
I understand the draw of putting turbos on everything. This is the guy who came within inches of convincing his friend's dad to put a turbo on a lawnmower. Some times you just have to walk away.

You sound right. I just like the idea of turbo charged single barrel slant 6 because no one has ever done it. For good reason. This is the same reason I don't want to do a v8 swap, because everyone does that to their old 6 cylinders.

I have nothing to add other than to say your inquiry has sent me down a 20 minute GIS rat hole and now I want a /6 hotrod. Really bad.

Yes, but you will need to source a hat to feed the boost into the carb and the carb will have to be converted to a blow through type. As long as you don't go overboard with the boost you should be able to increase the jet sizes enough to cover the fuel needs.
