Wink Optimal engine for street K24a2 or k20a2

Hey guys so i have a em2 rn and i want to swap a kseries into it. My goal is to pretty much make a street legal boosted race car by the end but rn i need to start with an engine. I drive aggressive and like to slide around turns and i also like to do highway runs so my questions are.

which engine will achieve a higher top speed

which engine will take off faster after blasting a corner

pretty much which engine will better become a street beast in terms of racing and potential.


also is this engine a k20a2 i cant tell at all

i do like burnouts dont get me wrong but speed is my main concern and aggressiveness. i dont want to buy a bmw i want to smoke them with my lil honda lol.

and i seacrhed the forums but i couldnt find the info i was looking for


also is it harder to swap a k24a2 in than a k20 in terms of parts and is the parts different or the same i cant seem to find a k24a2 part list only ones for the k20

this is my first build and i definitely want to do it right .

Re: Optimal engine for street K24a2 or k20a2

Both should make the same power roughly stock.

K20 = 2.0L displacement
K24 = 2.4L displacement

K20 has 11:1 compression pistons
K24 has 10.5:1 compression pistons

The better engine to boost is the k24, not only does it have more displacement but it also has lower compression piston, which are safer to boost with.

However, it's best to go with some purpose built pistons and rods for boost. They would be much stronger and probably around 8.8:1 compression.
