    Hello everyone, I have a '91 Civic Si. Is King Motorsports' "OEM build" (https://www.kingmotorsports.com/c-3...cess.aspx) legal in STC class, and what about Exedy OEM replacement clutch (P#08012)?

    If the Type R oil pump is the part that supersedes the original oil pump and the Modified oem valve job is legal you it would be fine. My guess is that the Type R oil pump is not the superseded part and is not legal. Also the Modified oem valve job seems like it would be illegal especially since they claim an increase of over 50 cfm which is about a 20% increase on a b16 engine. But it sounds like if you request that the valve job be done per the service manual and you use the oil pump that the dealer would give you for it you should be legal.
