I am prepping the Peripheral Port from Pineapple Racing for installation. The front pulley from my 86 NA 13B does not match the bolt pattern on the crank.
I am awaiting word from the engine builder on what ES he used.
My question is:
How many bolt patterns are there for the 13B Eccentric Shafts?
Pics to follow

the e shafts are all the same here, but the pulley hubs are not. theres 3 flavors
? to 81? symetrical pattern, theres a rivet to index the pulley
81?-85 same pattern no rivet, pulley goes on 4 ways, pull the head and put a dial indicator on the piston to find tdc
86-03, and maybe rx8, they move one bolt so the pulley hub can only go on one way unless you're really really drunk and have a drill
