I guess I opened the can of worms that most people don't know enough about and it ends in some sort of confusing debate as to what's better..
ok.. 1 - Twin turbo is HIGHLY effective and efficient on a V6
Mitsumishi 3000GT VR4 - 222 HP N/A 310 HP TT - 3.0L V6
300Z pretty much the same deal.. it's not a matter of how many cylinders but more of the displacement.
When you figure the displacement of a 2.0L 4 cylinder allows for more displacement to a turbo, 2.0L into one turbo, than a 3.0 V6 - 1.5L to a turbo the only drawback becomes the turbo lag, which isn't much of an issue with a set of smaller ceramic coated BB turbos. The only real concern would be the compression ratio and the crank. Everything else is tunable, or easily replaced (Fuel Injectors, Fuel line, fuel pump).
The fact is Turbo is much more capable of big power than a Supercharger is, but it does require a lot more work. I am in a unique position, because I plan to buy an engine in the next few months for whatever car I plan to buy... I won't be buying a car to go with that engine for at least another year. That gives me one year to get the heads done, the crank replaced, the valve springs replaced, and some lower compression forged racing pistons. I'm very capable of putting an engine together myself, so the real isssue is fabrication of parts (intercooling pipes and manifolds). That's what my questions was more geared for. Do the parts alread exist out there in order to turbo charger the car. I believe a twin turbo kit on a car like the crossfire is actually a bad idea, because of the dual intakes. I would be more inclined to attempt installing one larger turbo instead. I would have faster spoolup and a more efficient use of the turbo. So...
I'm guessing there's really nothing of the kind out there for turboing a Crossfire and what you get is what you got ... 215 HP is all you're really going to have, perhaps another 20-30 HP can be picked up with some aftermarket parts I'm assuming.
If anyone can link me to any forums or anything with a turbo charged crossfire that'd be great. I can probably get a good idea of what kind of work is involved and if I'd really want to take on a task like that.
My options on cars are a Crossfire coup, an Audi TT coupe, or a Toyota MR-2 Spyder...
The spyder isn't nearly as refined as the Audi or Chrsyler, I know, but has a lot of potential and is VERY fun to drive. The Crossfire is just such an awesome looking car, and pretty fun to drive from what I remember. Even with 215 HP it was pretty quick..
Well, thanks for the responses so far. and thanks for pointing me in the right direction..
