    17 lb injectors would be ideal. I did 19lb and I think that was a little much.

    You'll also want the airbox I believe because mine was different from the i one.

    Instrument cluster would be ideal too. You can swap over the mileage gauge that way your mileage reads the same. I would grab a 325i/s cluster too, there is a little plug that goes in the back that allows the cluster to move all the way or something? I don't remeber what it does..

    Grab the hoses attached to the head and intake as well to make things easier

    Feel free to PM me with any questions as my 85 received the same treatment.

          Head bolts, water pump, tensioner. Make sure you have the "i" throttle body.

            go through this thread, tons of people, myself included have spent hours upgrading this, to help out people who are trying to do exactly what your doing




            my post on this page...

            ...has a lot of little info that never showed up earlier in the thread as well as some big stuff.

            basically your list will not work there are quite a bit more parts you NEED (never mind do it while your in there parts) and pretty accurate lists are already made on that page. goodluck
