The poing is not to spin out and fly out in you're Autocrossing...right now I've got a new project...which will get two engines...just for the sake of me trying such a thing...and I'm gonna try to get as close to 50-50 with me in it as I can...

 

i think it all depends on what uyou are attempting to do with the car...

b-series-----drag racing and some autocross
d-series-----mountains,race tracks,autocrosses


so i think its all about what you want to do

 

horsepower is not what gets you up and moving, torque does, and d series usually have more torque than a b because of the single cam and longer stroke, dual cams have more high rpm power and a shorter stroke which will have less torque. (but its not like hondas have a lot of torque to begin with)
