I purchased a s200 with 3stage and no boost, let say if i want to add on turbokit to my engine, what are the thing needed for me to add with this s200?
what are the cost?
do i need to have a 3bar map sensor too?

It is $200 to add the boost option. IT will depend on how much boost you plan to run. If you run more than 10 psi you will need a 3bar map sensor. I would highly suggest that you just upgrade your s200 to an s300 while there is still time (http://www.hondata.com/s300upgradeform.html) as it gives you more options and is much easier to tune.
