Why not use this turbo charger?

[Macgyver]

Ok ok this might be a dumb question for some out there but Im gonna just put it out there anyways.

What would be the problem really w/ using a turbo charger that came off an eclipse like this one:

Mitsubishi turbocharger for the 1989-98 Mitsubishi Eclipse. The Part # is 49178-05200, and the Model # is TD05H-16G. This factory upgrade for the 89-98 DSM cars increases compressor flow by 25% at 505 CFM at 15 PSI boost Supports 340 HP. It has a larger 7CM2 turbine housings for reduced back pressure at high RPM. It is a direct replacement for the first generation TD04H and TD04H turbos. Second generation cars will require the 2G installation kit.
...whatever that means

What would it take to hook this up to a engine w/ a carb? Is it possible?

These turbo kits are like $2K plus installation. Why not find one on ebay or something and convert it. Ive not heard of this before so Im asking the question.

Im saving to buy another engine currently and Ive decided to drive the current one until it blows. Why not have some fun w/ it in the meantime, eh?

Well, it's probably too small for your engine, if it's intended for a small 4-banger. And the kit won't line up with your engine and intake. And you need a box for your carb, because the whole carb needs to be pressurized (technically not true, but carbs that are designed specifically for boost are expensive). And a different fuel pump to push fuel in against boost pressure.

There are turbo kits that are intended for the Chevy small-block. That would be the best route.

I agree that the eclipse turbo is too small, but why not use a twin turbo setup using 2 small 4 banger compressors. A twin setup might even be easier to plumb on a V8. There have been some really good articles in HOT ROD recently that discuss turbo charging. If you want a carb enclosure there is a nice cast aluminum unit made by Vortech for use with their centrifugal superchargers.

On the subject of 350 specific turbo kits, who makes them? and in what price range?

Theres two turbo charger setups on ebay for an SBC and one seems to come from AiResearch. The other ones for the Mitsu's are from the same company. I happened to run across an article in a Pontiac mag that details the addition of a diesel turbo to a pontiac 455 only costing under $900!!

The turbo is made by Schwitzer and can be found on ebay for about $400. Im wondering how much of a boost can be tolerated by a stock 350. Im not looking for anything outrageous. Just like an extra 50HP.

If you are only looking for 50hp or so, you will only need about 5-7 lbs boost. The Airesearch unit are very good. I have used them on 4 banger race motors in the past. The reason for the diesel units is for the higher heat. The casting are designed for very high heat conditions, such as high boost and high RPMs. One of the big things to look at is the housings. That is how you set when the boost starts biulding (RPM).
Gale Banks is one of the best turbo companies in the world and it would be worth the time to give them a call for information about your project.

So would a stock 81' be able to handle 5-7psi very well? I have 85K on her right now and she runs very well. Im wondering if this turbo would work out well or just blow the bottom of the engine in a month. Im not looking to race everyone on the street who wants to go, but if I can get close to 300HP w/ the current engine then perhaps I would want to hang on to this 350 for another 40-50K miles.

Swapping out engines w/ a new 330HP crate that costs $2300 is going to cost about $5k in total if not more w/ all the accessories that Im going to have to get as well and the labor. If I can get close to 300Hp w/a turbo setup for a "reasonable" boost level that my motor can handle for under $2k than Id want to go w/ a turbo and just swap out for a crate in a few years.

The cars Ive had in the past and currently do own have had high mileage, like in the 120-150k mile range. Two accords that I had both ran beautifully in the 140k mile range. Are these Chevy's as reliable? Am I dreamn' thinkn that 81' chevy 350 will go 150k miles?

There is no way to know what condition your motor is in; so I can not say how your motor will hold up. You do know that you will must likely need to pull your motor out to remove the oil pan to install the oil return for the turbo. I would also install a new high volume oil pump while the pan is off.
