    the motor mounts should be fine.
    your going to need a lot more than mounts.

    The auto to manual conversion isnt really that hard. I did it with my crx. The holes for every thing are all already there. The holes for the mounts on the cross member. Holes for pedals ect. I think you should be good to go.

    As far as ur swap goes u will need axles too and depending on what model Rex'r u have u may need more parts. Like the HF u have to change the hubs to an SI or an EX. What parts u use r going to depend on how much u want to spend and how avalible they can b to u.

    DPFI has 2 injectors...


    B16 had 4 injectors at each intake port...

    this is a HUGE diffrence... but the conversion is fairly easy

    ull need the pedal assembly from a manual car plus all the hardlines and the resivoir etc for the clutch, ull need to change your dpfi wiring to mpfi...either get the harness from hasport or do it urself, depends on ur wallet size...so put the engine into the bay itself ull need to make sum minor modifications viz mini-sledge hammer....if ur facing the engine bay ull need to make a dent in the rear right corner of ur engine bay to clear ur b series alternator and then ull need to smash down or cut off the old front motor mount....and ull need to address your exhaust i.e. bigger piping etx....oh yeah and ull need to run a vtec line...it truely is a simple swap just takes time, patience and money

    Send your wiring to us to have it taken care of, we'll add the extra backup switch wiring that's needed and pigtail it to your ECU with a pinout diagram so you won't be confused or have wiring problems.
    You've got alot more to worry about =) LOL One less thing, check us out.

    Just buy the harness from rywire, it'll save you lots of time trying to figure it out, they have good support too, i called and talked to peter about my harness and had a few sensors on the IM and around there switched around, now the only code i have is 20 which is the ground, which isnt bad, and i was told it would not affect vtec engaging.
