I have a JRSC on my 94 SOHC VTec Si. I am wondering if I need to change the timing or I should keep the factory timing? Any input? Thanks.

 

do you have any engine management? If not, yes you will need to retard the timing. I think I have it retarded bout 10 degrees, and im running a stock JRSC on a gsr. you will run into a prob with pre-denotation if you dont retard the timin.

 

10 or 11 degrees at the distributor is fine

 

Thx. I gotta check it out tomorrow morning.

 

do you have the JR map mod?

i'm using the JR map mod on my gsr motor and i have my timing set back one degree running 6psi. so mine is set at 15BTDC. setting it at 10BTDC makes your car run like *** IMO.

i use 93 octane though
