I have a 99 accord coupe, looking to swap out the engine and tranny to manual. What would be the best engine and trany to swap in? Ive been looking at the h22 but dont know much. Also where would be the best place to purchase a good engine?

 

Will vary slightly for the 99 accord, and didnt include info on a manual swap but yeah

H22 Swap Guide

I personally have swapped in a H22a4 into a 97 Accord, I am by no means an expert on the subject, and have since decided to go a different route and get away from the H series, but I will tell you what I know.

The different H22s:
H22a1-USDM rated for 190hp came in certain 92-96 Preludes
H22a4-USDM rated for 195hp came in 97+ Preludes
H22a-JDM rated for 200hp
H23a-JDM, essentially an H23 block with a F20b head.
F20b-JDM essentially a destroked H22

The parts you will need:

Parts to get from 92-95 prelude:
- Radiator Hoses (upper and lower)
- Heater Hoses (drivers & passenger side)
- Fuel rail (US spec only!)
- Header
