Ok i have a 90 rs 4 dr 5 speed integra with a b18a1. The motor is crap and i just purchased one today from a guy on craigslist. Motor looks grea, turns freely, but the fuel injection system on it is different than the one that was in my car. It has a few more vaccum lines, and looks like a few more electrical connectors as well. They both have stamps and stickers on them which are different. The one i purchased has a stamp of hf-1 and stickers with 02a0 and 21a0 on them. The one from the motor that was in my car has hf-3 stamped on it and 02b0 and 21b0 stickers. Now solution would be just to use the fuel injection system from my old motor on the new. Guess im just asking if that would be ok, would it cause any issues with the engine. Thanks for the help. Never swapped anything before.

Ok its the intake manifold, i dunno why i put that for title.
