Keep in mind the crank centrelines are different, the FE3 crank sits high up in the block and the BP crank sits at the very bottom. So the height difference once its actually installed in the car will be bugger all.
There is one on youtube with an FE3 in it. It was in Europe somewhere, looked completely stock.
If you need any pointers let me know, judging from the picture you arent using an FE3 loom and computer etc? Going aftermarket?
