I have to say from building one over the last few years, that there are a few books out there that can help. But nothing competes with the up to date info on the internet.
www.theturboforums.com is a great place to start.
Turbo mopars are few and far between, but the same principals apply to all engines. Just read, read, read...
Assuming you have an engine already (that has somewhat low compression), and you can fabricate yourself... you'll need
Turbo - Most chinese stuff has a small exhaust (turbine), so you'll need two if you go that route. Or you can use the popular Borg Warner S475 for about $700. Those seem to be the two most cost effective routes.
Waste Gate - China to Germany... you're looking at $150 to $700 here. I just have the cheap chinese knock off, but it siezed once already and I had to put a bronze valve guide in it)
Blow off Valve - Same as above. Less critical then the WG though, so you can probably skimp here more then anywhere. $100~$400.
Carb - If you're going the E85 route, I highly recommend Eric at Horsepower Innovations. CSU and C&S can also do them. $800
Carb hat - $200
Misc - Silicon couplers, clamps, tube for headers, hot side flange, ect... This part can be pricy. If you can use manifolds you'll save yourself a lot of money here. I have about $1000 into my misc material, but I used manifolds.
So you're looking at $2,500 minimum to put a system together. That being said... a S475 turbo on E85 will make a lot of power. Good heads and cam will get it to 1000hp. Junk parts will still make over 700hp with enough boost.
What are your goals. What is your budget? Those are the two most important things to know before you get started. Once you know that, people can help suggest parts to get you there.
Are there viable junk yard parts? Are there any cookbook combos that I could use?
