if you arent going to completely rebuild the motor, then yes it will blow and yes it IS NOT worth the time and effort...

and you must knwo what you are doing befor eyou can run LS vtec, you cant just slap a gsr head on a ls block, it dosent work like that..


but i would say just save the stock LS for right now, buy a turbo kit later and boost the fuck out that motor and when you blow that motor up, then its time for a brand new rebuild and then go LS vtec..

or not..its up to you


but unless done correctly it wil blow within a month or so..
