I've decided to stay with my D15b2, but my mind is going nuts trying to figure out what I need to do and where to get the parts from without having to weld.

I'm planning to swap to MPFI using a 92-95 EX Intake Mani+TB, EX Manual ECU, EX Harness Clips, and EX Dizzy.

I'm also planning to swap from Auto to stick shift using a 92-95 EX Tranny, EX Shift Linkage, Clutch Cable, Throttle Cable and EX Pedal Assembly.

I'm fairly confident I could do the mpfi swap with my mild soldering skills from working with electronics but I'm terrified at swapping out the tranny and getting parts to fit. I'm really hoping its a bolt on process but im ready to accept that its not.

Since I'm doing both at the same time so I dont buy a auto ECU for just the MPFI conversion and save a little bit of $$.

I've never removed an engine or tranny so working on that area of the wagon would be my first ever, but I'm ready to learn! I really want to do this but I want to have the right parts to start with.

Would the parts from a EF Chassis be more suitable for my wagon? Please enlighten me!

    I wouldn't use a any trans parts from the 92+ civics. I'm pretty sure the pedals are different, the mounts are different and that is a hydraulic clutch, which means you'd have to do some type of conversion to get it to work with your current cable setup. The MPFI conversion is quite simple and is compatible with the 92 ex intake manifold. The EX dizzy won't bolt up to your stock head. A lot of those parts are really going to make it way more difficult than it sounds like you are willing to do. EF parts would be way easier. I would personally do the EF trans and pedal assy, pm6 ecu and mpfi dizzy (not obd1). The mpfi conversion and obd1 conversion are quite difficult if you haven't done them before and worse if you are trying to do both at the same time. You'd be best to just do the mpfi conversion first, make sure everything works, then do the auto2manual. If you haven't done them before, do one at a time.

    Honestly after reading your reply it does feel like I'm putting way too much on my plate. I'll do the mpfi swap first. With whatever mpfi intake mani I find at the junkyard. I think I saw a crx with one? I get too hyped up lol. 92-95 is cable I believe... I know for sure 96+ is hydro. Or at least my ex was? Thank you!

    92-95 Civics had hydraulic transmissions. I've never seen one with a cable tranny unless someone converted it. Any intake manifold from an EF Civic/CRX Si will work for your MPFI conversion. I agree, you should take one step at a time and not get in over your head. If you can't handle it, you'll just lose motivation and want to give up. I just did a MPFI and converted it to OBD1 with a ECU jumper harness. It was my first time converted to OBD1 but not my first time to swap a Honda. I could see it being a somewhat difficult task for a first timer.

    I'll take a trip to my local junkyard and pull:

    88-91 Automatic MPFI IM+Sensors+ECU+Harness+Throttle Cable+Vacuum Hoses Connected to IM

    And later when I wish to convert to stick, Then until then and I have all the parts I'll worry about getting a manual ECU?

    Layspeed, Stampern, your right I checked my facts and its hydro! I'm learning!
    BTW Sweet CVCC layspeed, I was offered a 1976 5-speed cvcc wagon fully running for $3000 but I passed it up in hopes of getting my current wagon and because I have absolutely no idea how carburetors work. Yet at least

    Edit*
    Guys for my MPFI conversion, do I use the PM6 ECU or PS9?

    Im sticking with automatic for now.
  • stampernstampern Senior Wagonist
    You don't need a manual pm6 ecu when converting to manual. You can use the auto ecu with your manual conversion. I was thinking the ecu code for mpfi auto was pm9, could be wrong though. Correction - the ps9 will work for the mpfi - don't remember wat the pm9 was for. If you find a ps9 get it.
  • JeebuzJeebuz New Wagonist
    I will thank you very much! Ps9 is from a auto 88-91 civic sedan EX

    Its not to hard to do either and if you go OBD1 it makes it even easier by running all wires to the jumper pretty much plug and play

    I'm sure I can do it bro, but I'm going to start off step by step. I'll do the mpfi swap, then convert to auto, then not sure, either mini me to start off with or a engine swap. or leave in and time to start my first homade turbo build! I have a new bud at my work that has done all that stuff so I'll be alright! I'll stick to 8psi with my weenie rods
