Recently I've been thinkin about putting in an inexpensive twin turbo set-up for my 86 Z-28 305 4bbl. I saw it on one camaroz28.com members' 3rd gen. I've also found a place to buy turbos for a good price (Ebay), So what I need to know is:

(1)what turbo/super charger will fit (Garett, Turbonetics, etc..)
(2)other than the boost controller, what will I need?
(3)Can HKS parts work (intercooler etc..)
(4)Are there any companies that seel intake bonnets other than steedspeed.com?
(5)What internal parts will have to be beefed up?

I'm NOT pulling the 305 out, rather building around it (I have my reasons). If I'm looking at this right, it should'nt cost a fortune and add about a 50%-75% horsepower increase across the whole powerband.

 

It may not cost a fortune for a supercharger setup but it very well may for a turbo setup because there are a few pieces that are not made for our cars that you need for a turbo setup including turbo headers. There have been a couple of setups made that had manifolds for single turbo's, but none are made currently so you would have to either find a set of the old ones, or have some custom made which gets expensive.

I don't want to start a debate about which is better, but I think it would be a heck of a lot easier to go with a vortec type super charger. They make the generic ones and the inlet for the carb and you wouldn't have to worry about exhaust mods to work the thing like with the turbo.

If the 305 has a stock bottom end you probably don't want more than 6 psi boost. And since you won't be doing more than 6 psi boost you probably don't need to go with an intercooler.
