Another Engine we considered using was an RB26DETT (Nissan Skyline R32 Twin Turbo). But we ran into a similar problem. This engine could also be purchased with a 5 speed transmission with the option of either AWD or RWD. While we run in to the same problem with the RWD tranny i have no idea about the AWD? would an AWD tranny be any easier to install into a FWD than a RWD? or could the AWD more easily be converted to FWD? I don't want all the extra weight and lack of mpg that comes with an AWD, so i would much rather convert this one to FWD.
