Does the 20b fit on Fd subframe.

ok. Thanks.

The trick to make it fit is to chill the 20b block in a large commercial fridge to shrink the motor , then wrap it in dry ice, and then quickly install into said project fd. Once thawed, it will expand and a tight fit and clean install results. Don't forget to add oil to the recipe!

I inflated my FD, much easier than than freezing the engine block. Once inflated you have about 5 seconds before the air escapes and traps the engine in an unwanted position.

since i dont have a large freezer or an air compressor, i let mine sit in the FL sun for about four hours.....expands the metal and allows for easy engine install

i couldn't afford a freezer, a heater or the sun. i just went to the DMV and City Hall and had my 13B's name officially changed to 20B. as a matter of fact, i had my FB's name changed to FD. so, yeah, now i have a 20B FD. i'm awesome.

seriously though, the simple answer is it's not going to just bolt right in. there are a few ways to go about it, some are better than others. the point is ... research.

The word swap is what gets us. After doing one, its not an engine "swap" more like a replace-half-the-car. LOL

You aint never lied! Actually just diving in and ACTUALLY doing some work is how I was able to move my engine back. Hell I'm actually getting ready to install my 6 speed t56 with the fd manuel tranny bellhousing. After playing with some parts laying around, I'm confident I can pull it off without having to buy new parts to convert to a push style clutch that's required when using the auto bellhousing.
