1991 prelude question of the day

[RobertF1]

aight i have a 91 prelude si with the b21a1 motor i blew it up

I race this car on the race track and the rules say cars the have 2000cc's or greater have to add 140lbs to the right side of the car

heres the question

would it be better to buy the b20a5 and not carry the lead or buy the b21a1 and carry the lead

is there much difference between the two
besides the piston size

thanks

Just get a B20a or a5 long block and keep all your B21a1 parts and accessories. I owned that setup for a while before just sold it. It runs very well.
