Thank god, Jeff...

There's so much heresey in this thread, it's not even funny...

Let's straighten some things out.

PR4 can be OBD0 or OBD1
-1990-1991 Integra's are OBD0
-1992-1993 Integra's are OBD1

You have the option to go OBD1 or OBD0. To convert to OBD1 (which is easier to tune than OBD0, then you just have to buy a couple more parts)

Your EF is OBD0, currently

If you have an SI, it's already MPFI, and thus you won't have to do an MPFI conversion.

www.boomslang.us has a plug and play for the low-low seeing as you can get one for a pre-MPFI setup. Buy it. It's quality. It's cheaper than Rywire. This is ONLY if you plan to convert to OBD1. If you're staying OBD0, don't worry about it.

Your DA axles WILL work with your SI hubs. You won't have any problems. Direct fit.

Your shiftlinkage will NOT work from the DA. You will HAVE to buy a new one. Check Avid Racing for the low-low...or spend quality money and get a hasport. I purchased an Avid. I hate it. It works...but it's not quality. Get yourself the Hasport.

Your motor mounts will have to be purchased. If you stay with a cable transmission (what you currently have) then get the EFB1 (if I remember right) kid for a CABLE transmission. If you convert to Hydro tranny, get the correct kid. I purchased Avid mounts (I think) and I hate them. Spend the money and get Hasport would be my advice.

The above information was typed with the idea that you plan to STAY as an OBD0 setup. If you plan to go OBD1, please advise so I can assist you further.
