03 Civic B18 Engine Swap Help
 

Hello my names Tyler and I'm kinda new to the Honda scene. And I'm buying an 03 Civic originally an automatic that has no motor or tranny in it. But I found a B18 (long block) with a 5 speed tranny. I've read up on B18 Engines, but I can't find what I need to do a full swap. And I need help on what all I need to do the swap. If you have any help feel free to text me at (417) 437-7334

Thanks

With your generation Civic (01-05) you cannot swap in a B series without extensive modifications. Even if you get it in, good luck passing emissions.

Anyways, I believe you are pretty much limited to the D17, or a K20. Go K20z1 if you have the money.

What kind of extensive modifications are we talking about? And why wouldn't it pass emissions?

Older engine in a newer car is usually not emissions friendly.

I never played with 01-05 Civics, so I am not sure of what would be needed. I would do some research. Honda-tech.com may be a better source of knowledge for something like this.
