Yea, the jdm b18b intake manifold looks like the 91-93, but this guy is telling me that the throtle body is different and also the IM, he says is missing a sensor, something like mac sensor i dont know, I haven't had a chance to get to the shop. The worst thing is that the "mechanic" don't want to swao the intakes with old b18b1, I think that will do it right?
