After taking Brian's thought on rewelding the bolt pattern on the exhaust manifold I am even more motivated to do this. The twin tubular manifolds are fairly inexpensive and easier to weld on than the cast, so first I will have to grab a set of them. I am thinking of adding new ears on them similar to how MMS adds to the rear hubs for the 5 lug pattern. Grab a set of BNR34N1 turbines and then start bolting on things such as downpipes, cold piping and BNR3X front mount. With a forward facing plenum it should be a real unique Rb20. Have to make sure my brother-in-law keeps mailing me the parts. Time to re-pull the RB20 and put it back on the stand. More mods time...Will definitely have to start saving pennies for the injectors and cams now...
