  1. How to stop crank from turning off TDC while doing belt

    3rd Gen
    Hello all as you have probably seen in my last posts i have been having trouble with my timing belt for some time now. I did figure out how to get it over the cam gears after alot of messing around with it I found that I could move the gears very slightly to get just enough room to jam the belt...
  2. B20A Engine Block Water Jacket Interface cover

    3rd Gen
    3G family, I wanted to know if anyone had a picture of what is missing from the Transmission side of the B20A engine that I have. On the B21 and the other 3G engine variants, it's a circular aluminum plug with a counter sunk hex head. If removed, it gives access to the water jacket. The B20A...
  3. My B20/21 hybrid build plan - All input welcome

    3rd Gen
    Hey guys, I recently (finally) started work on the engine I plan to use to replace my worn out b21. I'm piecing together parts at the moment, and the block/crank/rods are at the machine shop as we speak. Basically what I want to do with this motor is overbuild it slightly, so I can have the...
  4. B20 Swap clutch question.

    3rd Gen
    I have a JDM B20A and just had to order a JDM B20A Transmission for 88-91 (they didn't specify 88-89 or 90-91) I need to find out what clutch I need to get. theyre Japanese so do I get a Japanese specific clutch or am I fine getting any clutch kit that auto zone says fits the 2.0?

    Hey guys.. so this is my second prelude. My first was a light blue 1986 SI. it was an automatic and was pretty much mint. It had pioneer speakers and an aftermarket stereo..

  7. JDM VS NORTH AMERICAN B20A (3rd gen)

    3rd Gen
    Hey guys, I finally have my Prelude engine ordered.. with months of research and reading about the options I have for swapping out my B21A1, I finally rounded up the money and decided the B21A1 REBUILD was not worth it without replacing the FRM sleeves. (which I can not afford, nor can I find...

    Hey there fellow luders. I thought I'd introduce myself to the forum since I've been leeching for valuable information without posting anything. Been an owner of a '91 Prelude Si B20A for about a year now on and off with a couple breakdowns and issues with smog. I recently got it up and running...

    3rd Gen
    Hey, I just dropped a b20a into my 89 si. I have most of the wiring harness hooked up, but I am not getting any power to my engine bay fuse box. I attached a power wire from the battery to the fuse box and had power though. I am not sure if I do not have the harness hooked up right or...
  15. is a engine swap worth the trouble

    3rd Gen
    I have an 89 prelude (i think that means it has a b20a5 engine in it) and I have been reading up on engine swaps with the h22. From what i have read getting the h22 engine hooked up and working in a 3rd gen prelude is a lot of work and a lot of local shops won't do it for you because of all the...
