i have a b20/vtec with a jrsc on it..and i cant find the right belt from crank to alt. pulley and jackson doesnt seem to know anything about it...

i wanted to know if they are the same size so i can just order an LS one or am i just screwed?

I would doubt the LS pulley will fit.

I'm not a SC guy, did you have to replace the OEM crank pulley?

Do you need a longer or shorter belt ?

Take the belt to a auto parts store and tell them what you need, there's a belt out there that will fit.

i have a stock b20 bottom end with the stock b20 crank pulley and a gsr head with a gsr jrsc...and i dont have a belt that fits from the crank pulley of the b20 to the alt. pulley for the jrsc...jackson only has belts for an LS and a GSR..

the b20 crank pulleys are larger than the b16 or b18 pulleys yes. I have both so I know. You would think jackson racing has came across this problem about a million times by now but im not surprised by anything anymore.

measure the distance from the alt pulley section of the crank p. to the alternator with a string and then use the string to determine the measurement of the longer belt you will need if you still want to run the b20 pulley or just replace the 2.0 pulley with a b16 or b18 pulley using the corresponding belt.

The high boost kit comes with a Jackson racing pulley which is the size of the b20 crank pulley. So they belt is like 4pk800 might be what you need that was the supplied belt that came with my blower. It was for the high boost kit. I opted to use my stock size gsr pulley till I get a chance to buy an fluidamper pulley.
