i currently have a 1999 almera gti with sr20 rocker roller engine,bottom end blown!!! do i have this engine repaired or do i buy my mates pulsar(complete car) for conversion? i have heard mixed reports about the rocker roller engine and could really use some advice as to what engine to start from,is the pulsar engine the same head or hydraulic tapetts and cams?, my head is a 2p2 5r and block is 53y,red injectors and low port?
