I've done my research before I order the engine and it has arrived here. I put them side by side and compare the two engine.. and match my list of things to do and change from one engine to the other but it's not going so well.

I'm swapping a 94 B18b1 into a 91 Integra which had a B18A1.
From my searching online last week, I took some notes down on what to transfer over to the B18b1, but it doesn't look like that's all it is.

Here's my list.

B18B engine into 91 Integra LS

- Use B18A1 Distributor and Throttle Body and plugs
-- B18B Distributor and Throttle Body has different plugs

- Use 91 Integra injectors and resistor box.

- Replace oil pump, water pumps, timing belt.

What's the easiest way to do this?
The intake manifold looks alot different from each other.
Can't I just swap the B18A1 Complete Intake manifold with throttle body onto the B18B1 Block?

I'm looking a list of things to transfer over onto the B18B from the B18A.

Desperately need help. Engine arrive and I'm really confused. I did search and thought I had it down but now i'm cluess.

Thanks in advance.
