The cost is in the 6 - 7k range.
A 3.6 will not fit in my non egas 99 without alot of wiring work. A 3.4 will fit with no problem.
As far as cost goes a year ago when I looked into it the 3.4 install would have been in the 15K range.
After the cost of the sc and the turbo I should have done the 3.4
I could have rebuilt a mean 3.4 for the money I have spent but all is well.
My opinion on these upgrades is simple. If you have the cash or the time to do it yourself do the 3.4
If you want similar power for half the price get the turbo.
If you want to supercharge the car find a used one from someone selling their car.
There is currently a 1 year old sc for sale.

The current phase we are tweaking the A/F ratio and I expect another 10 across the board.
The next phase is an increase in the boost to 8psi. I expect 20 -30 across the board, all of this of course is to the wheels, not the crank.
Please ask any questions you may have.
