K24a4 Swap (accord) - Whats Needed

[SinisterCivicSi]

There isnt much info out for this swap since its not a popular choice to swap. i recently put this motor in my car and am VERY happy with the results. not only did i choose this motor for its fuel economy, i also chose it for the price - you can pick one up usually for under 800 bucks!

K24a4 Specs:

- 2,354 cc 2.4 liters in-line 4 front engine
- 87 mm bore, 99 mm stroke
- 9.7 compression ratio, double overhead cam, variable valve timing
- Unleaded fuel 87
- Fuel economy: EPA highway - 34mpg -- EPA city - 24mpg
- Multi-point injection fuel system
- Power: 119 kW , 160 HP SAE @ 5,500 rpm; 161 ft lb, 218 Nm @ 4,500 rpm


here is some info that will help others that want to do this swap, but had a hard time finding the info as i did.

i will update this thread with more info if i get it, since the old thread was typed right after the swap, i might have forgotten a few things in this one. hope this helps out!

Non-popular? I think the K24A1 and K24A4 are the 2 most commonly swapped engines, only because you can get a short-block for as low and $300; re-sleeve the bitch (depending on how bad the walls are), swap out for TSX parts and call it a day =)

thats why i picked one up... because it was so inexpensive! i have been asked why i went this route with the motor because of the "no vtec" but i dont really care, she's cammed.

thanx 4 the info. did you have a clip on the right side of the motor not go anywhere cuz there is a cylindrical object with a female end for a sensor but my wiring harness doesnt have the clip. and i have that part that bolts to the motor from the crv but the part that connects that to the bracket on the body wont fit its like the holes arent far enough apart?? and did u change the upper radiator hpse b/c b4 it went into the motor from underneath but now the black male end point up not down so i did some modding.

Your a3 mid pipe should fit. I ran my mid pipe from my a3 for six months and had no problems. Good info btw.

are you referring to the egr port? looks like a coffee grinder? i call it my expresso machine. yeah you have to remove that stuff and the links for the parts you need are in post #1. they are very inexpensive.

as for the side motor mount bracket, make sure you have the right one. honda sent me the wrong one the first time and it didnt fit either. check the link i posted in #1 and you will see the picture of the mount you need. if you have the top motor mount - its the wrong one. you can use your ep top mount... you just need the crv SIDE mount.

i didnt change any radiator hoses, i used all the ep coolant housings, parts and lines. you cannot use the a4 tstat, water pump or the coolant lines...they wont bolt up... trust me we tried.

Your a3 mid pipe should fit. I ran my mid pipe from my a3 for six months and had no problems. Good info btw.

now this is the tricky part.... because the motor sits taller, some applications wont fit - they will hit your swaybar. HOWEVER... we kinda found out by accident that the 2002 front oem sway is the ONLY oem sway for the ep that will clear a type s race header for this swap. others were buying a civic ex oem sway and if you get the 02 ep sway, that should fit with no issues.

now as for the midpipe, the ep and dc5 should be very similiar if not identical in the bends (not the diameter, the dc5 is bigger). i used a type s midpipe w/ the type s race header so i didnt have to worry about an ep midpipe. the only ep part i used in the exhaust was the oem axleback - until i had my hks cut to fit the race header.

Yeah my civic is an 02.

can you run a k24a4 on a stock ecu w/ upgraded fuel injectors (310cc)?

[JDM-ELY]

Boosting the k24a4 will be a good idea?should i change 2 the k20a3 head?......do i really need the hasport gasket? Thanks

[SPECIAL K20A]

well i just blew my motor just wanted to know if the k24 of the elemnet work in my ep i have a reflash i found one with 53000 miles on it for 300 bucks will my manifold bolt up

[SinisterCivicSi]

OMG 300 is a steal for any running K24! dude THMotorsports has a kpro ready to go, just have to ship it... so there is no wait... if you need tuning options asap.

i dont know anything about the reflash so i cant speak on it. i am very limited on kpro, just enough to load basic kals, and datalog.

manifold will fit if you tap the head for the coolant source. if not, get the rbc IM and that has the hookup built in. you will also need the a4 manifold gasket (to cover the built in line).

read the stickys in this section, they are super helpful.

[SPECIAL K20A]

would i feel a big difference between both motors now anothing my a3 i was pulling it too 8000 rps will the k24 take that abuse or whats the highest i can pull it

[SinisterCivicSi]

my a4 is at 7200 rpms. you can take a2's higher. not sure about the a1's

sinisterCivic..thank for the nice write up.. im geting ready to do this swap.. i got the motor for a straight trade for my k20a3..so im swaping the a4 for now so i can have a car in the mean while im building a1 bottom with rsxS z1 head.. my question is what do i use on my kpro there is an option k24accord with intake exhaust and headers..is this the option i want to run???

and should i run the 270 or the 310 injectors..?

thanks! the origional had alot more detail but this has most of it in there. there is a map for the k24a4. i cannot recall right now if they have one for exhaust and header but i HIGHLY suggest you upgrade to the 310 cc injectors. if your running rich you can always trim the fuel back in kpro. i used my 270cc oem injectors and i burned them up from maxing them out. granted i have stage 2 cams with boltons but you would rather have injectors that you know can handle the load, than burn yours up like me and risk fucking something up. if you plan on modding more then 310's are the way to go.

i cannot stress enough to DATALOG as soon as you get the motor running. find out what your air/fuel is and tweek it if necessary...check for knocks too.. running lean is a bad thing.... trust me on that one.
