You’re going to reuse the waterpump housing assembly from your stock engine so all your accessories can go back in the right areas, you can use an uncut rbc intake manifold with an adjustable throttle body from blox, k-tuned or Hybrid racing. You need the PPA passenger side mount bracket usually this comes on the k24 already but if not, you can source it from your local dealer. Clutch and flywheel from your current setup can work as well.
Just blew the k20 in my ep3. Looking at getting a k24a as they're around 30-35% cheaper in the UK compared to the k20a2. This would be my first engine swap but I have a mate whose currently building a N/A K20 so I could get help from him when needed. A video going in depth in your k24a ep3 swap would be a goldmine👍🏽
im doing a a2 head on a k24a1 block with some aftermarket type s rods and pistons with upgraded valves skunk 2 ultra intake and alpha throtte body and a plm exhaust manifold and some upgraded injectors. hoping to hurt some scatpack feels
Man this is awesome information I just got me a TSX motor. I'm trying to swap in a RSX base 5-speed. Mechanically similar to the EP 3. I have question about the transmission can I use on the TSX block the base 5-speed? Does the K20 A3 intermediate shaft bolt up to the TSX K24 block? And I can use the RS X axles? Also does the accessories AC, power steering from k20a 3 bolt-on k24 A2?
Yes, I used my ep3 trans. Everything bolted up perfectly. Change over entire accessories from the a3. Helps to have them side by side. Also, I kept the RBB manifold for simplicity of the water port on it. Tb adapter is needed and your intake won’t fit perfect it may needed to be flipped, rotated and or cut to fit
What about using a 04 TSX trans on a EP3 with a K20a2? Do I need anything different to run that trans correctly or does it all work without any alterations?
for the JDM K24A, if you swap the whole water pump / alternator assembly from the stock K20A3, that also brings with it the thermostat. So no need for an RDX thermostat housing. Or am I missing something? I am going through this very swap right now.
@@tlikethedrink that's interesting. I used ep3 thermostat and housing and the k24a water hoses out of the top of the housing. Engine swap is still ongoing (I'm slow as hell) but hopefully first start this weekend.
@@tlikethedrink thanks! right now i'm just waiting on the RDX 410 injectors but I might just use the included 310cc instead for now. besides that just small details like dealing with evap (i'm using a skunk2 manifold & throttle body) and figuring out the wiring for trans speed sensor (the whole reason I started the swap was my stock ep3 trans grenaded when the drain plug went MIA for about 20 miles). new trans is from a base 05/06 RSX (not ideal but it is what it is) so different speed sensor location and method. I should be able to utilize the kpro (vtec academy has a decent video on this process), just taking it slow as i haven't done much wiring in a car before and don't want to cook the ECU or something
@VTEC Academy I'm doing this for an RSX but I'm adding the 50 degree VTC. Do you know if I can run K24 with 50 degree VTC from 02-04 RSX type S ECU OK?
If you can use the ep3 intake manifold why can you use the throttle body and do you have to tap the coolant ports or will it just bolt up I’m getting a lot of mixed signals
For jdm k24a on the ep3 would I have to change the Injectors to the ep3 also along with the accord throttle body Will it run right with the stock ep3 ecu
@VTECAcademy rn I have stock ep3 exhaust and the manifold for ep3 it feels very pointless and not much faster up top than a k20a3. Going to upgrade exhaust and wondering what I will need to do to run the k24a with rb2 intake manifold. I have k24a from Honda odyssey absolute motor. Should be 200 hp 168-171 tq. Stock a3 ecu still no k pro yet
hey buddie....AWD CRV Transmission on a 96-00 EK5 k24 swap.....what engine mounts & brackets must i use w/EG subframe......Hasport has the EKK5, is that the right one?...my car comes AWD from the factory so i must goign to install an AWD crv trans.....
It is most likely the header and yes it is common on the K24 swap in the RSX, EP3 and 06-11 Si. We used Hasport's stiffer rear mount to control engine movement and reduce contact.
@@VTECAcademy But am deleting the P/S pump since it’s in an EP3. So I suppose I will need to change out crank pulleys and an EP3 belt will work? I thought the deck height will matter. Why about water pump?
@@VTECAcademy Thank you! Would you also recommend or know of a header I can use for the swap ? I heard you need a specific one to clear the front sway.
Great video and lots of info - just what I was looking for. I have a UKDM (Euro) EP3 CTR in AU with a K20A2 head and block, PRA ecu (K-Pro'd) with Toda N2 cams. What is the best block to do a K20A2 Frankenstein build with?. K24A3 from the CL Accord Euro and K24A6 from the Odyssey are fairly plentiful here - are these OK? I also saw elsewhere that the K24 stroke of 87mm could be an issue as the K20 stroke is only 86mm - many thanks once again.
I’m not really familiar with those two engines, but it looks like the 83 engine may have a piston that doesn’t make contact with the head. You’re going to need to set the head on and see if the piston makes contact when you turn the engine over.
@@VTECAcademy Many thanks for the reply. A little further digging shows that the K24A3 is basically the K24A2 for the AU/EU market (Accord Euro etc) with the same compression ratio of 10.5:1. I misread the 86mm vs 87mm stroke issue - it's actually the K20 has a bore of 86mm, and the K24 has a bore of 87mm, so once again need to check for piston to head contact
I have a jdm k24a2 block with a k20a2 head on the block. I got the oil cooler parts too. I have the water pump housing but no water pump nor all of the belt accessories. My ep3 k20 is stamped as “k20A” it doesn’t have a 3 stamped on it so I think it’s the jdm version of the k20a3. Can I take idler pulley, pulley tensioner, ac/ps, water pump, and side mount bracket onto the k24?
I’ve got a question for U, I’ve got a build / restoration going, Mazda 818/808 coupe, and I would love to go with a K24a2 with a 6 speed red, but can’t find any previous swaps done into this type of body. I would love it if U could give me some advise so I would be looking in the right direction ❤️😉

how did it blow?
I've been thinking about getting the jdm k24 for my ep3 that currently had 265k miles on it!!!!!!!!!!!! Thanks please keep up the great work!!!!!!
Except the block bracket, you should have all the parts you'll need for the swap from your EP3 engine.

You don’t have to swap the accessories from jdm k24 the 09-14 rsx uses the same layout

What about just adding the TSX head on the ep3s A3 block and tune for true vtec ?
Hi, does the stock exhaust manifold and catalytic from Ep3 works on k24a2?
Hello going to put a k24a rbb3 in my ep3 with a 8th gen civic si transmission what do I have to do to make the trans work in the ep3? Thank you
What about using a 04 TSX trans on a EP3 with a K20a2? Do I need anything different to run that trans correctly or does it all work without any alterations?
Different mounts and modify either the trans or shifter.
You forgot to mention EGR housing
Which ECU do I need to use?
Do I need kpro?
And does the k24 have any EGR stuff I need to mess with?
To get the full potential from the engine a KPro is needed.
@@VTECAcademy do I use my stock ECU or one from a car with a k24? If so I assume it has to be the one that already comes in a manual?

What did you end up doing? I’m currently trying to figure that part of the swap out.
What year RDX for the thermostat housing?

With stock cams, yes.
@VTECAcademy so the 50 degree VTC needs regulation? Needs Kpro then? Should be able to start and move it ok?
I’m swapping in a k24a4 into my base 06 rsx. Do I leave the egr valve on or do I have to buy a plate to block it off.
Either get a block off plate or a TSX upper radiator hose outlet.
Question is your website working im teying to look for you information diy section but website not working
Thanks for the heads up! We'll figure it out.
If you can use the ep3 intake manifold why can you use the throttle body and do you have to tap the coolant ports or will it just bolt up I’m getting a lot of mixed signals
You need an intake manifold adapter.
Question for the k24a jdm motor do I have to change the vtec solenoid?
For jdm k24a on the ep3 would I have to change the Injectors to the ep3 also along with the accord throttle body
Will it run right with the stock ep3 ecu
What throttle cable can be used for k24a swap in ep3 with rbb intake manifold
What intake manifold work best for jdm k24a in ep3
The one that comes on the K24A works great.
