the engine has good compression and doesn't burn any oil but at 180XXX miles i just don't wanna slap the JRSC on there and have it blow out on me in the next 5K miles and then rebuild it...you know start from the ground up, get the engine rebuilt, new clutch to handle the extra power along with an LSD, and then the supercharger....and yes i will have it tuned as soon as the JRSC is installed.....but nobody has answered my questions as far as HOW MUCH AM I LOOKING AS FAR AS COST FOR REBUILD???? and WHAT SHOP (i know there is a bunch here) WILL GIVE ME AN HONEST PRICE AND DO QUALITY WORK AS WELL AS TUNE IT WHEN IT IS DONE????
