I have just purchased a front frame clip complete with a 69000 mile motor and drive train with plans to rebuild over the next while, One option is to turbo charge it I have found a stroker kit, I am looking for more torque for the trailer hauling I do.
Is there a turbo kit out there?

I don't know much about turbo inatalls but the costs are big. First you relly need forged pistons. Ben there, done that. 1100 bucks for the forged Ross pistons in my new caddy install. Might as well do forged rods. If those are going to be used and they should,,,, you're going to do the whole motor. Cheapest with all new parts is about 4k.MINIMUM. Now,,,, 1 or 2 turbos,piping (welded stainless???) intake(custom one off) Oil returns(oil pan mod)oil feed. Pop offs and 2 wastgates. Custom fuel injector rails, injectors. Need a really good FI controler. Bigstuff 3 or F.A.S.T.(2k) Better upgrade that radiator.(800) Doing the math in my head looks like 8 to 10 grand easy. Fabbing up and mounting the tubos and manifolds(3 of them In,Ex) would run 500 to a grand. better know how to program the thing. Thats expensive too. Shoot,,, go with a stroker Caddy OR,,, an 8.1 (496ci) Dave Lenzi conversion. Both would be less. Turbos would be altitude compensating( no loss in mountains) but dave stated he has plenty of power at altitude. The L18 (chevy engine code) is a real truck motor. Its a 454 block thats .060 over with a 4.25 stroke. A 454 is 4.25 bore with a 4" stroke. The L18 is 4.31b X 4.25 stroke. This is what Dave is using. Roller lifters,Factory F.I..Its a truck "stroker" motor. I hope this helps. If you need someone to weld exhaust manifolds I know some one who has done several tubo installs and makes his living fabricating. Good Luck,,,,,PL

Or you could go with a blow through carb and save a lot on the custom EFI stuff. If you are using a caddy engine go with forged rods and pistons. For the turbo mounting try getting some ebay BBC turbo headers and have a shop weld a caddy flange on it. You can also run some elcheap turbos but that would not be advised. Expect to pay about 700 each for some good ones. More if you want bb turbos...

T'is interesting that all the kits are the same price and make the same horsepower gains,(80 HP) regardless of the vehicle it's installed in.
It'll ad 80hp to your 500HP Ford GT or your 120Hp Honda Fit. Seems a better deal for the Fit owner.
Really, all these electric turbo/super chargers are bogus.
There are vids on youtube showing a gas operated leaf blower making measurable hp on the dyno. Not 80 hp, more like 20 hp and they are using 1-2 hp gasoline engines themselves.
Lets see; 1 hp =746 watts (if you have the mythical 0 loss electical motor which no one has) 746w/13 volts(operating volts)=57 amps. ZZZAAAPPP.
I think it would need to be slightly more robust and require marginally larger feed wiring than the pictures show.
And 0-29K rpm in 1/10 of a second! Not with me anywhere nearby thank you.
These things have been around a long time, Still interseting folks. Sad...
If your serious about forced induction I suggest first purchasing reading material. "Maximum Boost", by Corky Bell, is an excellent start. Probably the easiest technical book on this subject to read. It can be found on Amazon. Read the reviews!
It will not answer all of your questions but it will determine the questions you will ask.
The $25 you will spend will more than pay for itself should you decide to go the forced induction route.
The book has a far far greater chance of adding HP to your engine than the electic blowers.
Hope this helps

Doesn't Ford use a combination electric/exhaust turbos in their machines now? Supposed to make up for the exhaust-powered lag with the electric one, but I don't know if it is cycled part time on/off.

Not sure, might be a pat of their new eco-boost system, I know Garrett was developing an electric assist turbo to spool it faster and also experimenting with VGT turbine housings. I know the Garrett G37 BB turbo was a VGT turbine used on the powerstroke diesels, and made boost damn near off idle. you really gotta hear a 350 Superduty with one of these things, sounds like a damn jet engine spooling when you touch the gas. problem with VGT turbines, is the increased EGT of gasoline engines play hell with the small parts in them. last I heard they were getting those issues solved. I wanted one of these things for my 2.3 liter turbo mustang (think SVO) but I keep hearing still working on it. such a turbo would be really nice in a GMC and make a stupid amount of torque...

Jay,
There is no kit, but we can quote one for your coach.
It is simpler to quote one withe Twin turbos as there will be less
exaust pipe running around.
Contray to some, you do not need to change to forged piston, but can
get more differance in power if you go with lower compression ratio
when using turbo, also you'll need to use port EFI if you want good
results.

This guy who used to work for Shelby specialises in low cost centrifugal supercharger conversions, I think he did an Olds 403 once.
http://www.wynjammer.com/
Turbo city used to do a blow through Turbo conversion for the Olds 403 in Trans Ams back in the late 70's mid 80's.
Mecham Pontiac used it in their Macho TA Trans Ams.
History now, never seen one of these kits off a car for sale, but you may be able to copy their setup from pics.

The Mecham kits were originally made by H-O Racing Specialties. It was a blow through carb single turbo configuration, using the Rajay 301E.
