what do i need to switch from a d16y8 to b20b in a 1999 Honda Civic coupe.
A break down of parts.

 

The first thing you need is the willingness to put forth a modicum of effort, which you obviously haven't.

Engine Alignment
Blinker Fluid
Engine Rotator Splint
Cross drilled brake lines
Piston return springs
Muffler bearings
Crank gear liner

that should get you started.

 

 

The engine must have a minimum of 40% oil, 58% metal, and 2% water. Gets the best performance.

 

Check the link in my signature. The first post will be a good reference point for you. I am planning a b20 swap in my 2000 Honda Civic and all the research I been doing will be found there.

Also, you'll yield more fruitful answers if you typed this kind of question in a Google search bar than a post on H-T. This place is full of first posts like yours and all of them get the same response.
