So from what I understand (from searching) you CAN put a K20A3 head onto the K24 block...? Or is that incorrect?

If it is true what are the power gains people are getting from that? I assume more torque? What about HP? At what RPMs?

On hmotorsonline they have the K24 long block for like 850 bucks. That sure beats that price of a turbo for now, etc and if it has a decent amount more power than my EP3 it seems like a good idea.

I assume all of my EP3's bolt ons will still work too, since they bolt to the head and not the block.


But mainly I am just curious to see what the power output numbers are looking like, and how high it REVs and the compression ratio and whatnot.

THanks guys.

 

i think you read incorrect.

k20a2 head onto a k24a1 (crv) block. redline decreases to 8 grand. now a 2.4L with more torque. HP goes up maybe 10-15 (more depending what mods you have done to it) hp but you have an excellent torque increase. Instead of 139lb (varying) you get like 160-175 varying. k20a3's are worthless unless you fully build them or boost.

the k20a3 vtec-e (vtec-efficiency) for fuel economy is what kills ya since you don't have the vtec the k20a2 utilizes.

never knew the k20a3 was vtec-e...good info

 

So A3 won't go on there? Dang!


What about just putting a straight K24 in there... Any good benefits of that?

 

as in swapping for k24a2(tsx)? nothing wrong with that.

you can put a k20a, k20a2 or k24a2 and you'd be satisfied for N/A.

 

Ok. So what are the power stats on just a stock K24 engine. Would it be nicer to go with then my A3 or should I just boost my A3 and be done with it?

 

what are your goals.. what do you want?

 

High 13s to low 14s on a very streetable commuter that still gets decent gas milage and has full interior (no race stuff)...

 

all motor or boost?

 

Well I am not sure. I am thinking boost. I have read so far that the K20A3 handles boost pretty well. That could be an option and I am sure a less expensive one than going NA too.

 

then turbo it is. You could make easily 300hp stock, run 12's with a turbo kit w/o any major mods and be streetable. just get a rightfully sized turbo for your car. the turbo kits i have seen like greddy, hks etc... they are all small turbo's. just remember if you are going turbo you need to upgrade your fuel pump to a 255.

 

is a k20a3 really vtec-e? Has anyone swapped a k24 into an ep3?

 

yes to both questions

 

if all you looking for is 13s i would just put a jackson racing supercharger on the a3 or if you wanna swap i would swap in a k20a2 with some light cams and some nice bolt ons. i ran 13.6 in my rsx with just bolt ons but i think i might just go boost in my rsx just to shut up some EVO guys i know

 

13.6 with bolt ons? That is like a second quicker than stock. Damn.


Well I am thinking LIGHT boost and LIGHT turbo. Something to spool quickly to like 6 to 8 pounds.

We'll see what happens, new tires and suspension are ready to be installed as of right now. That will make a noticable difference.
