what is the best crank pulley for a turbo b series?

 

does the vehicle have p/s and a/c ?

 

ac yes ps no

 

stock if you are keeping ac

 

yeah id keep you stock crank pully. The aftermarket ones dont have a balancer in them. Ive heard of people having the stock one machined down

 

^yep
the aftermarket ones do more harm than good, like killing your oil pump causing your motor to be gonzo

 

well i have herd of some weight transfering one...reason i am asking is for me there is no "stock" one motor is being built from the blokc up

 

Get one custom made at a machine shop. Have a tolerance of no more then 0.010 of an inch of play at 10k rpm. That is as balanced as you will ever want them. We had one on a B series for alternator only having zero play at 13k rpm. Put it on my brothers race EF.
