Fresh from the machine shop as well, the freshened up, ported & polished DOHC head. Used turbo cams to increase the exhaust side of the cams. After all, if you know 1st gen DSM’s, then you should know the exhaust side of these cars was done more of an after thought. The turbo cams have a higher lift on the exhaust side then the non-turbo cams, but all other cam spec’s are the same. And for only $35 on Ebay, it was a no brainer up grade. The headers were also sourced from Ebay with down pipe for $78, & I cleaned up the ports my self with a dremal.
