Need a little help from the TT BT nerds

As I said before, I'm working out cutting out the massive bloat that exists in the BT books making a quick reference guide for everything you can use to customize your mech. Recently I finished do all the weapons and my next project is engines but I need your guy's help!

The BT wiki doesn't give enough information on the eletronic parts for me to make the wirte up on that section.

What I need covered is cost/tonnage/critslot and any special rules for indivual heatsinks, DHS, BAP, TAG, NARC and any i am forgeting excluding tornement play rules as this quick reference is for casual pick up game play ( also excluding clan rules becuse fuck dirty clanners who need better numbers to be good at games :) )

Form:

ITEM     Tonnage     Crit slots     cost

DHS           1                    3             Arm and a leg

Heatsink     1                   1             Just the arm

Ect

Thanks in advance to any one willing to contribute to this project.
