obd1 p13 ecu will work great, a full tune is even better. obd1 h22 distributor, and the conversion harness from the crank sensor pigtail to the new distributor (assuming you use the h23a engine harness).
or you can get an obd1 h22a1 engine harness and obd1 h22a1 injectors (still need obd1 distributor too)

Sweet thanks. Where can i get that conversation harness? And also since its technically the jdm h23a vtec would there be any restrictions on what i use? Sorry for not point that out in my initial post...

Yes you will need to convert to OBD1 if you are 90-91. 92-93 are OBD1 already.

You will need p28 ecu with a base map of Neptune or Crome of the H23A Vtec Motor. Phearable.net or Xenocron sells the ecus ready to rock for $150.

You will need a Custom Motor Mount Kit if sticking with H transmission.

We sell the ESP DA H22A Motor Mount Kit... PM me. You will need the Packaged Deal with the Traction Bar System to clear the bigger motor. Check out our website for detail how to of the swap and parts list.

I was actually going to try h2b unless i find a trans cheaper then the adapter which i probably will. If i stick with h2b will i need the h22 full kit or just mounts for the motor? Ill pm you some more questions i have later. Thanks for the info man!

H2B is a different animal of a swap. Will sit further forward and up... Will have hood clearance issues. Street/Strip H trans... Drag B trans... with H trans motor sits further back like it is suppose to with a lot less work. Yes will still need our ESP DA Traction Bar System whether H2B or H trans for clearance with the bigger motor. PM me.

H2B uses B series mounts
