tell you though, I have been told that a good upgrade for the NA (aka my 91 2+2), is the cams. My plans are to install those as well sooner or later. I am going to have to replace my valve cover gaskets and a couple of others so planned to do the install then. See my profile. I enjoy the NA and am picking it up in the morning when I get off work after having an RPS clutch installed. But I also have been doing alot to the TT which has become my first addiction/drug with no hope for any form of sobriety from it seen in the future. Good Luck, Dre
