Alfista friends, I come to ask for professional advice, so I can choose a modern Alfa for a new category in my country.
To start I must be honest I've never had a modern Alfa.

There is a new category supported by the FIA, for stock cars.
Stock means: Only add air filter, exhaust, suspension, brakes, and tires Yokohama Advan Neova for everyone. and (no chip).
All cars will be disarmed of their engines to check who are normal and then mark each piece by technicians.

Challengers: type R, nissan SE-R, BMW etc.

The technical regulation:
a) cars that have no more than "200 horsepower. "
b) capacity cylinder capacity: 2.500 cc. (max)

c) This is what makes it interesting:

Formula final weight (including the driver, and fluids)

(HP + TORQUE) / 2 X 14

example: for Alfa 156-2.5
189(hp)+161(ft-lb)= 350 divided by 2=175 X 14 =2.450 pounds of weight.

If you look, the final weight depends on the horsepower of the original car.
A list of calculation for the differences with other cars and weight:

MODEL---------HP----FT-LB-----Original weight--WEIGHT CATEGORY--Difference

Alfa156 2.0----150---133-------2,756 lbs--------1,981 lbs-------------775 lbs of removing
Alfa156 2.5----189---161-------3,097------------2,450-----------------647
Alfa155 2.5----163---159-------3,020------------2,254-----------------766

Hond 1.6TypR--182---118------2,293-------------2,100-----------------193
Hond 2.0 typR--197--145------2,700-------------2,394-----------------406
Nissan SE-R----140---132-----2,450-------------1,904------------------506

if the weigh is the first enemy?.
more power = more weight....
Simple: "What Alfa is the best for this?."
please help

Thanks Vsix
The weight I found online between various data, perhaps in some years have been mixed weights, it is not important, what makes it important is that the weight of our regulation: power & torque, not what the car brings.

The analogy of this is, which Alfa is more faster, removing nearly 700 lbs

more simple, that Alfa is faster with this final weight:

Alfa156 2.0 ------ 1, 981 lbs ------------- 775 lbs
Alfa156 2.5 ------ 2, 450 lbs ------------- 647 lbs
Alfa155 2.5 ------ 2, 254 lbs ------------- 766 lbs

Thanks for your time!
