DO NOT GET A ATTS TRANNY!!!

ATTS is that traction control system that came in the type SH preludes. Aparently, the ATTS transmission is not swap-friendly, particularly with Civics.

Wiring wise, it shouldn't be that big of a pain. USE THE STOCK Si HARNESS!!! Your Civic Si is already vtec, and already has a 4wire O2, so no surprises there. It would be a good thing for you to get the OBD2 engine harness with your motor, as you will need to remove the pins from your OBD1 harness, remove the pins from the OBD2 distributor connectors and then put the pins from your OBD1 harness in the correct spots on the pins of the OBD2 plugs. This sounds harder than it is. The helms manual will be your friend.

As for an ECU to run the thing, forget converting to OBD2. You can chip the P28 that came in your Civic Si to make it run http://pgmfi.org/phorum/read.php?f=42&i=86&t=86 a H22, or you can acquire a 92-95 P13 ECU ($$$) and add wires for knock sensor. If you are really worried about the IABs you can even make the P28 operate them. http://www.nitroburn.com/pgmfiwiki/index.p...php/AddIABToP28
