Right, I'm in the middle of my engine swap and I've discovered that the G25A1 that is in my '92 Vigor doesn't quite match the G25A that I bought from a company down in Texas that got it from Japan. In the quick look-over it seemed to match, but when I started pulling stuff off the A1 I noticed that the distributor isn't the same, the intake manifold has some extra goodies and some vacuum lines are extra on the A model. Do any of you know what else I'm going to run into as I progress further into the depths of my machine? I assume that I can just swap the distributor over to the new engine, but do I have to swap the intake manifolds as well? I figured I go right to the most knowledgable source and see if you guys have run into this problem or where else I can go to find out.
