i have an ek rally car and i have a full b18c4 engine sitting in the garage, i want to make the b16 faster using parts from the b18 but not sure what would benefit it? ive noticed the throttle body is bigger, im gettin dc2 camshafts for the b16 can anyone just tell me what can i use off the b18 and buy to get the bhp and torque up, and the end ill buy a hondata ecu and get it remapped but i want to nkow wt mods to do first

 

1) Why not just swap the engine? Will this put you in a different class or is there some reason you want to use parts from one engine to put on the other?

2) It's probably none of my business, but why would you put your phone number out on the internet for everyone to see? Not a very good idea.

If you want a better idea of what to swap, start googling 'B16a2 to B18c4 parts interchangeability' and read to your heart's content. You probably aren't going to get a lot of replies to your post that will be constructive until you have more information listed about your exact setup and ask very specific questions about parts you are wanting to swap.

 

B18C4's best parts are P72-bottomend and cylinderhead itself (smaller combustionchambers etc.). Cams are slightly "bigger", but throttlebody is just same size (60mm). If you do not have cylindercapacity limitation, use that engine. Just get different intakemanifold and header.

What gearing do you have, btw?
