You've actually seen this motor?

Ask him what the engine ID# and year is for the motor he is using. This info will be very helpful since right now we are just guessing as to what motor it could be.

Granted, I don't know everything about D16A1 motors, but I am currently building one and have done tons, upon tons, upon tons, upon tons of research on this motor. The ports on a D16A1 intake manifold are oval as opposed to round like the EW/D15, and the bolt pattern is completely different between the motors. I suppose using the carbed intake could be done, but you would have to redrill the holes for the mounting studs and port match the intake.

If it is a D16A1 motor that he is using, ask him how he got the carbed manifold to work on this motor. I'm curious because this is the first time I've heard of someone using a stock carbed manifold on a D16A1.

Did he also mention that you will need the trans, CV shafts, knuckles, shift linkage and tranny mount from an 86-'89 Integra in order to swap in this motor? I'm not trying to talk you out of this motor, I just want to make sure that you are well informed, because it sounds like this guy isn't telling you everything.

Now I have to ask, why would anyone want to starve the potential of the D16A1 by using a 1.5L carbed intake? By using this manifold you are creating a bottle neck from the carb to the cylinder head. If you compare both motors, you'll see that the intake ports on the D16A1 are considerably bigger.
