If you're sending the harness out to have it converted, Tweak is the guy you want. He's done this countless times and does good work.

Boosts off the line a lot quicker, I prob won't since I'll have two ct26 turbos on hand. I saw an artical with a time attack 700hp st205 that was supercharged. You may be suprised what you can pick up a BIG SC for though.

That twin charged 205 is a masterpiece of engineering, not something most could do off the shelf. Its even riding on a $50k gearbox.

Superchargers are a lot more difficult to set up than turbo's. At the end of the day it is infinitely easier and thousands cheaper to simply buy an oem supercharged car. The st185 does not have enough clearance around the pulleys to have a custom crank pulley and supercharger belt setup. If you wanted to run a proper supercharger you would also need a new hood. In my opinion unless it is a twin screw it isn't worth doing and even then you will make less power than a turbo.

Does your 3rd gen engine not have a ct20? You may need to fully assess what you have going on before wasting time on pipe dreams.

12psi. Anymore is a waste of time, the exhaust housing is too restrictive.

This is a great place to learn. I think I was worse than you when I joined 13 years ago. I was trying to come up with things like use a SC from a aw11 and a ct26.
So did you 3rd gen come with a turbo? If so, then that makes things better. If you plan on using the turbo from the 2nd gen, then that is a step backwards.

I getting my engine/tranny/ECU hopefully this week. My 2nd gen has an upgraded turbo I believe. Hopefully my garage has enough ceiling clearance to get the engine out. I don't have a carlift so I'm trying To figure out how to lift the car over the motor/tranny. I think it shouldn't be too bad. My friend who's helping me and I built a lifted wrangler In small garage so this should have enough Clearance. Gonna start pulling the Motor this week. I'll post up my progress.

Take the engine out from the bottom instead. Just lower it onto a dolly with the gearbox and roll it out.

Gonna, just trying to think how to lift the body up. Floor Jacks with blocking? Can't really use a chain fall- don't want to break the rafters in the garage. Maybe I'll get some huge jack stands. I dunno yet.

+1 to that....easiest way once u figure out what to use to raise the car
Some people use the engine hoist to raise the front end by attaching it to the bumper reinforcement bar (not the RC one, its weak)
There are pictures floating around on the internet of this process being done.
Otherwise a car hoist would be the way to go about it.....or if your a backyard mechanic you could do it with a forklift :P
