i know i've been MIA for a while but i've been back for a little while...i spend most of my time just reading through the posts. i finally have a question: can a 1st gen B16 block be mated to a B16A2 head without any problems? what i've been thinking about doing is buying a 1st gen block and building it up and swap it out with my B16A2 block and use my current B16A2 head. Are there any reasons why I shouldn't go this route. the reason i wanted to go this route is cuz the 1st gen blocks are really cheap. i'm going for a moderate setup for the street, give me some feedback. my setup is going to consist of the following: -b16a2 head: ITR cams*, dual valve springs, titanium retainers. -1st-gen b16 block: eagle rods, CTR pistons, ARP bolts. -bolt ons: AEM cai*, JDM ITR header, test pipe, mandrel bent piping, spoon muffler, skunk2/ITR intake manifold, erick's racing 66-68mm TB, aftermarket FPR, V-AFC. -drivetrain: stage 2 clutch*, 8lb. flywheel*. *=i already have it. thanks.
