how much will this affect handling and weight
 

just out of curiousity how much does putting a ls1 or a 3 rotor affect handling and how much weight will it add to the car? Also will the power potential outweight the compromise in weight and handling? thx (i did a search btw)

relative to the cars own weight, those motor swaps do not add significant weight to adversely effect handling.

the power potential is tremendous and of course provides benefits that also bring along problems... rear end failure, traction issues, etc.
