I am swapping my non vtec stock engine from my 94 civic lx for a vtec jdm d15b engine. The mechanic that is doing the swap says my distributer on the new engine is faulty. He says it has a warped bearing and the car won't fire. I've read that you can swap the distributers from my stock engine to the d15b, but my mechanic says its impossible. Any suggestions? I have a bad feeling my mechanic doesn't know what he's doing.
