GSR crank pulley fit a b18b block? thanx.

 

Yes it will.You will need to play around with belt lenghts.

cool cool....I take it that you don't know what kinda belt to use then..ok.

 

The belt would probably be the same as the GSR belt. Also, the GSR crank pulley would be an underdrive pulley and possibly free up a few HP.

 

Here are some lengths I have on file that you can reference to go to the store with:

GS-R Alternator Belt = 4PK785 (4PK310, that's 31.0" converted from 785mm)

CR-V PS Belt = 4PK900 (4PK355)....all B-series 4-rib crank pulleys should use the same diameter PS pump drive so all of the belt lengths are the same. Give it a try.

ITR AC Belt = 4PK790 (4PK310, but I found 305 works better for me)....since the ITR AC drive is smaller in diameter, go up another half inch to 310 or 315.

You'll probably find that the engine revs a little more easily with the GS-R crank pulley, and even more so if you had an ITR crank pulley.
