Hello all this is my first post in this part of H-T! lol I have been working on B and D series motor for awhile now but me and my buddy are about to swap a F22B vtec into his 1991 Accord DX that currently has F22A4 in it. Now im guessing it will be mostly the same as a B or D swap. We will be building his new F22B within the next few weeks. Now i have a few questions to get me started.

We will be running the F22B ecu. Can I use the 1991 F22a4 Harness and wire the vtec directly to the ecu like on my B series?????

Whats the max boost we can run on the stock F22B long block?

And is there anything else I need to know about this swap.

Thanks guys for all the help.
