So, in order to serve as an example of how simple these new mech construction techniques are, I took a few minutes to convert two extremes in mech constructions, the Wasp WSP-1A and the Atlas AS7-D. Here's what they look like:
Wasp, WSP-1A
20 Ton Mech Chassis:
Chassis Internal Structure tonnage (tonnage/10) = 2 tons.
Chassis Internal Structure points (tonnage/2 for ct, half rounded up elsewhere) = CT 10 points; RT, LT, RA, LA, RL, LL all 5 points
Chassis Gyro Tonnage (IS tonnage/2) = 1 ton.
Chassis Maximum Armor Potential Tonnage (tonnage/5) = 4 Tons.
Chassis Armor Values at 3 tons (10 points per .5 tons, distributed at 2 per torso, 1 per limb) = CT, LT, RT 12 points; RA, LA, RL, LL, 6 points
Cockpit = Standard Mech Cockpit for 3 Tons (.25 tons for 5 structure points, .5 tons armor for 10 points, .25 tons for sensors and comms equipment, 2 tons for cockpit and life support systems)
Engine Rating of 120:
Standard Engine Tonnage (.05 tons per rating point) = 6 tons
Mech Movement (rating/tonnage) = 6 hexes/12 inches
In-engine heat sinks (1 per 25 engine rating . . . the minimum required to make the mech function, to a maximum of 10 "free" before additional tonnage is required) = 4 Double (the new standard with advanced technology) = 8 standard cooling.
Jump Jets:
Number of Jets = 6
Jet weight (tonnage/100) = .2 tons per jump jet
Total weight in jets = 1.2
Weapons Payload:
Right Arm - 1 Medium Standard Laser = 1 Ton, 1 Crit, 4 Heat, 6 Damage, 6Hex/12" range.
(This is a base item. Formula for each advancement: +3 tons, heat X2, damage +3, flat +3Hex/6" range increments. Formula for each smaller size: Tons/2, heat/2, damage -2, fixed 3Hex/6" range.)
Left Leg - 1 SRM 2 = .5 tons, 1 crit, 1 heat, 4 damage (2/missile)
This is a Base Item (formula for each advancement: every two tubes adds the stats of the base weapon system, stacking heat, damage, crits, etc.)
Left Torso - 1 Ton Standard SRM ammunition for 120 missiles (providing 60 shots to the SRM2)
Total Payload Tonnage = 2.5 tons
Current Tonnage:
2 tons structure + 3 tons armor + 1 ton Gyro + 3 tons cockpit + 6 tons engine + 1.2 tons Jump Jets + 2.5 tons weapons = 18.7 Tons.
Max Heat potential: 5 from weapons, 3 from jumping (.5 heat/jet, rounded up) = 8 heat (standard movements not included because they'd generate less heat @ 1/walk and 2/run).
-With 8 standard cooling, this is a completely heat neutral mech.
Using NEW technology the same mech is built with 1.3 tons to spare. In order to consume those tons . . .
-Increase armor by 6 points (.3 tons at 2 points per .1 ton, 2 points to ct, 1 point to each side torso and 1 point to each leg).
-Increase the engine rating by one movement increment, to a 140 engine (7 tons, total), also giving the mech one more internal engine heat sink (5 Double) to a maximum cooling of 10.
This also changes the mechs' movement capabilities to 7Hex/14" walk and 6Hex/12" jump.
18.7 + .3 + 1 = 20 Ton mech total.

Atlas, AS7-D
100 Ton Mech Chassis:
Chassis Internal Structure tonnage (tonnage/10) = 10 tons.
Chassis Internal Structure points (tonnage/2) = CT 50 points; RT, LT, RA, LA, RL, LL all 25 points
Chassis Gyro tonnage (IS tonnage/2) = 5 tons.
Chassis Maximum Armor Potential Tonnage (tonnage/5) = 20 Tons.
Chassis Armor Values at 19.5 tons (10 points per .5 tons, distributed at 2 per torso, 1 per limb) = CT, LT, RT 78 points; RA, LA, RL, LL, 39 points
Cockpit = Standard Mech Cockpit for 3 Tons (.25 tons for 5 structure points, .5 tons armor for 10 points, .25 tons for sensors and comms equipment, 2 tons for cockpit and life support systems)
Engine Rating of 300:
Engine Tonnage (.05 tons per rating point) = 15 tons
Mech Movement (rating/tonnage) = 3 hexes/6 inches
In-engine heat sinks (1 per 25 engine rating . . . the minimum required to make the mech function, to a maximum of 10 "free")= 10 Free Double (the new standard with advanced technology), with 2 extra in-engine heat sinks required = 24 standard cooling.
Additional tonnage of heat sinks = 2, setting total engine mass to 17 tons.
Jump Jets:
Number of Jets = 0
Jet weight (tonnage/100) = 1 ton per jump jet
Total weight in jets = 0
Weapons Payload:
Right Arm - 1 Medium Standard Laser = 1 Ton, 1 Crit, 4 Heat, 6 Damage, 6Hex/12" range.
(This is a base item. Formula for each advancement: +3 tons, heat X2, damage +3, flat +3Hex/6" range increments. Formula for each smaller size: Tons/2, heat/2, damage -2, fixed 3Hex/6" range.)
Left Arm - 1 Medium Standard Laser = 1 Ton, 1 Crit, 4 Heat, 6 Damage, 6Hex/12" range.
Right Torso - 1 Standard AC/20, 12 tons (2 base + rating/2), 10 crits, 5 Heat, 20 Damage, 10 Hex/20" range.
(Base Item = Standard AC/2, 3 Ton, 1 Crit, 1 Heat, 2 Damage, 20 Hex/40" range. Formula for advancement: 2 Tons + rating/2, Crits = rating/2, heat = Rating/4 (round up), damage = rating, Hex range = base - #crits)
Right Torso - 2 tons Std. AC/20 Ammo (shots per ton = 100/rating), providing a total of 10 shots.
Left Torso - 1 SRM6 = 1.5 tons, 3 crit, 3 heat, 12 damage (2dam./missile w/ 3, 2-missile clusters)
(base item = SRM2, .5 tons, 1 crit, 1 heat, 4 damage (2/missile). Formula for advancement: every two tubes adds the stats of the base weapon system, stacking heat, damage, tonnage, and crits)
Left Torso - 1 Ton Standard SRM ammunition for 120 missiles (providing 20 shots to the SRM6)
Left Torso - 1 LRM 20 = 6 tons, 4 crits, 4 heat, 20 damage (1dam./missile w/ 4, 5-missile clusters)
(base item = LRM5, 1.5 tons, 1 crit, 1 heat, 5 damage (1/missile). Formula for each adavncement: every five tubes adds the stats of the base weapon system, stacking heat, damage, tonnage, and crits)
Left Torso - 2 Tons Standard LRM ammunition for 180 missiles each (providing 18 shots, total, for the LRM 20)
Total Payload Tonnage = 26.5 tons
Current Tonnage:
10 tons structure + 5 tons gyro + 19.5 tons armor + 3 tons cockpit + 17 tons engine + 0 tons Jump Jets + 26.5 tons weapons = 81 Tons.
Max Heat potential: 20 from weapons, 2 from running = 22 heat.
Using NEW technology the same mech is built with 19 tons to spare. In order to consume those tons . . .
-Upgrade the remaining .5 tons of armor, giving the chassis its maximum tonnage.
-Install a Heavy Gyro, increasing gyro weight by 50% (2.5 tons), and giving the mech 10% more CT internal structure points (rounded up), CT structure now = 55.
-Turn the SRM6 into a "Artemis Streak 6", adding 3 tons.
-Install a C3 Command Unit for 5 tons, allowing the unit to give his side +2 initiative as well as control a C3 network.
-Upgrade the Medium Standard Lasers in the arms to Large Standard Lasers (4 tons, 1 crit, 8 heat, 9 damage, 9Hex/18" range) for 6 tons total difference.
-Install two more heat sinks, bringing the total heat sinks to 14 and the standard cooling to 28.
New Max Heat potential: 28 (8/LL + 8/LL + 5/AC20 + 3/SRM6 + 4/LRM20) Heat from weapons, 2 from running = 30 heat.
-This is not quite a heat neutral mech, but very close. Refraining from firing the LRM or SRM each round would retain heat neutrality.
81 + .5 + 2.5 + 3 + 5 + 6 + 2 = 100 ton mech total.
