How to K24A3/K20A2 head; Now let's get with Z3

manzoHCI · Apr 5, 2011

Hi to everyone,
Im new Italian member, here u can find my introduction:
http://www.k20a.org/forum/showthread.php?t=89393
I know many topic about Frankenstein swap were open in the past. I open one new, because I need to learn step by step every operations to do with the pieces and the components that I can find here in my country.
I already look and read many topic about this argument, something I understand but something not. I would have one topic with all the informations, we can put a link of other topics, but is important also copy and paste the explain replies.
In these topic, please help me by writing simple english and posting pics.
Sure Im going to ask also silly questions so apologize me, please. Here in italy nobody try to do this swap, so you are my teachers

I try to write short questions, for each step and components and divide my topic in block, such as Main Parts, Other Components, Fitting and Modify, etc
My target is to swap this engine inside civic hatch ’93.
So let’s start

**************************************************************************************************************

NUMBER 1= MAIN PARTS ---> That's OK
Block:
Here in italy I can find K24A3. Is a good base to start? I read that a good one is the K24A2 of Acura TSX because has the oil squirters.
A3 no have. Is that a problem? Solutions?
Rods and pistons are ok of K24A3? Why I read is better use them from K24A1 /2?
Here I can find if im luck a complete engine for a cheap price
http://allegro.pl/listing.php/search?sg=0&string=accord+2.4
ANSWER
K24A3 is very similar to the K24A2.
Already have the piston oil squirter

You will not need to change a lot of the parts.
No need for the K20A head.
No need for the oil cooler.
No need to swap pistons or rods.

Swap the K20A2 oil pump.

Head:
K20A2 complete head, with camshafts, valves, retainers and springs

ANSWER
That's OK

**************************************************************************************************************

NUMBER 2= TRANSMISSION ---> That's OK
Which is better? I think to looking for K20A or K20A2 transmission. Both fit plug&play? (plug&play u say ‘bolt on?’) Other tranny that u suggest?

ANSWER
The K20A tranny has LSD inside.
The K20A2/A3 tranny has no LSD.
You can use any K-series LSD, but you need the ring gear.

**************************************************************************************************************

NUMBER 3= OTHER COMPONENTS ---> That's OK

ANSWER
K20A2 Crank Pulley ---> NEVER NEED
K20A2 Alternator ---> NEVER NEED
K20A2 Thermo housing ---> NEVER NEED
K20A2 Starter ---> NEVER NEED
K20A2 Oil pan, pump and chain guide --->K20A/A2 oil pump NEED FOR IMPROVE-IS BETTER
K20A2 oil cooler ---> NEVER NEED
K20A2 water pump ---> NEVER NEED
K20A2 Starter ---> NEVER NEED
K20A2 Crank baffle ---> this is in the oil pan. You can use the K20A2 oil pan, and a K20A2 baffle
K20 intake gear fot VTC system ---> NEED

BRACKET NEEDED
Honda part 11910-PPA-000
http://www.k20a.org/forum/attachment.php?attachmentid=1178

**************************************************************************************************************

NUMBER 4= WATER PUMP AND OIL COOLER ---> That's OK
K24A3? K20A2? If I want oil cooler I choose K20A2 water pump.
It fit plug&play?
http://image.modified.com/f/17410708+w750+st0/0406_scc_hybrid_06_z.jpg
The K20A2 water pump is on the right. The hole with the coolant dripping out is the supply for the oil cooler.
Then let’s fit oil cooler by S2000joint cooler

http://farm5.static.flickr.com/4103/4954630575_606cf17007.jpg

ANSWER
K24A3 already have oil cooler so no need do nothing.
OEM K24 water pump is ok, if u can find K20a2 one better

**************************************************************************************************************

NUMBER 5= OIL PUMP ---> That's OK
For fit K20A2 oil pump need do some modifies.
What? Any pics?
It is better to replace this heavy pump by the k20a2 oil pump that didn't use balancer. If you do that, don't forget to plug the secondary oil line on the k24 block that is to lubricate the bearing of the k24 pump. This means tapping only this oil orifice? No more?

http://image.hondatuningmagazine.co...htup_0511_04_o+k24_engine_block_k20_cylinder_head_build+oil_pickup_assembly.jpg

I also read about use S2000oil pump. In which case? For fit it exist a kit for assembly?

ANSWER
Only 1 orifice. When you take off the K24 oil pump, and put on the K20 oil pump you will see. It is very easy to see.

A picture while modify the k20a2 oil pump
http://img830.imageshack.us/img830/3941/qweac.jpg

General Rule is about:
7500 for K24 oil pumps
8400 for K20A/A2/Z1/Z3 oil pumps
8900+ for S2000 oil pump

**************************************************************************************************************

NUMBER 6= CRANK BUFFLE ---> That's OK
Tell me everything about it please. I don’t know what is it. I only know it need from K20A2

ANSWER
Don't worry about this. If you can fit it with the K20 oil pump then keep it. If no, then don't use it.
http://img638.imageshack.us/img638/9431/unledhggh.jpg

**************************************************************************************************************

NUMBER 7= CRANK PULLEY ---> That's OK
You gotta use your K20 one! Notice the size difference between the TSX and K20. TSX at left and K20 at right. If you forget to use your k20 crank pulley you will DIE trying to put the belt on. Which tensioner I use?
http://gallery.8thcivic.com/albums/engine/Picture131.jpg

ANSWER
Use the K24A3 crank pulley. K24 tensioner

**************************************************************************************************************

NUMBER 8= EXHAUST HEADERS HONDA CIVIC HB 93 ---> That's OK

I see on hybrid racing K headers swap. In this case that we reach more high with K20A2, which headers can fit? Are there any bolt on? Or they need custom modify?

ANSWER
Shipping from USA to Italy will be very expensive. I recommend buying a good header 1 time, and not buying a cheap header now and a good header later. ASP and SSR make good headers

**************************************************************************************************************

NUMBER 9=TIME FOR THE SENSORS ---> That's OK, same links of N°14 "WIRING"
i will be transfering all of sensors and components that attach to the block. Use all of your old stuff. (WHAT MEANS? SENSOR FROM K20A2 BLOCK? WHICH? LIST AND PICS PLEASE ) Everything fit the same except for these few sensors' clips. Here are the differences...AND SO? HOW CAN I FIT THEM?

**************************************************************************************************************

NUMBER 12A=AXELS --->That's OK
Which ones?
-hybrid racing K swap axels?
-external joint Bserie; axle K20/K24; internal joint K24/20 (if K24 int.shaft/if K20 int.shaft; OR INTERNAL K20 JOINT IS SAME K24?)

ANSWER
Do you use the Hasport engine mounts? If you use Hasport mounts you can use 'hybridation' mounts with B-series external joint and DC5 internal.
You can also use DSS 2.9
http://hasport.com/store/index.php/accessories/axles/kax.html
http://www.driveshaftshop.com/

with hasport mounts
YES 1- rsx base axles and then swap the inner joints between that pair of Base axles. So rsx base socket is same B series socket (in my case DC2 socket).
YES, BUT ONLY IF USDM DC5... FOR SOME REASON, JDM DC5 AXLES ARE LONGER THAN USDM DC5...2- DC5 axles and then swap the inner joints and put Bseries outer (so DC5 have 36mm socket?)
YES 3-rsx intermediate shaft=dc5 intermediate shaft=EP3 INTERMEDIATE SHAFT?
EP3 ARE TOO SHORT, YES, CAN USE EP3 HALF SHAFT4- why EP3 axles dont work? different lenght? intermediate shaft can work with rsx axles?
NO! ACTUALLY, USDM EP3 IS TOO SHORT... USDM RSX-S (36MM) IS THE SAME AS UKDM EP3 CTR AND SAME LENGTH AND ARE 36MM 5-usdm=ukdm?

*******************************************************

NUMBER 12B=INTERMEDIATE SHAFT --->That's OK
ANSWER
if you use the K20 transmission you need the K20 intermediate shaft, K24 needs K24 intermediate shaft

**************************************************************************************************************

NUMBER 13=POWER STERRING AND HOOD CLEARANCE ---> I have the topic, i need to read

NUMBER 15=ECU ---> I have the topic, i need to read
Which ECU I need to use? Finally kpro, but for start the engine and use the car soft,no runs, no nothing, only daily use?
ANSWER
you will need K-pro so you can bypass the immobilizer and turn off ODII
http://www.k20a.org/forum/showpost.php?p=603905&postcount=6
**************************************************************************************************************

NUMBER 16=HP AND TORQUE --->That's OK
With this simple set up, which values I can reach?

ANSWER
Power will depend on a lot of things. If you have a good header, and good tuner for K-pro ECU then maybe 230 WHP, 175 WTQ. With good camshaft more power. With ITB more power. For beginning engine, I say keep it simple

Re: first K24A3block+K20A2head from Italy. Be patient and help me step by step

thats alot of questions.

I can answer one, you dont need the crv timing mount that is only for type s rsx and civic si 2006+.

I also do not think the k24a3 is bolton with the k20 head, the k24a1 and k24a2 stock engines are the only ones that work with the k20 vtec heads. any other block needs different pistons.

sorry can't help anymore then that.

i update the first post with the new info.
The questions about sensors,ecu and wiring i mark 'ok' but i want read again all the links for understand. So about that i ask more later.

Now quickly questions for complete:

NUMBER 2=TRANSMISSION
K serie fit bolt on?
i want LSD so:
1-buy K20A tranny
2-fit aftermarket LSD: which tranny? K20A2 or K20A3 tranny? which is the best?

NUMBER 3=OTHER COMPONENTS tell me please if what i write is correct or not. write OK or NOT OK and what u suggest
K24 Timing Chain+ Guides+Tensioner : are already on the engine and i can reuse them
K24 Timing cover: is already on the engine and i can reuse it
K24 Headgasket: is already on the engine but is better replace with a new one

Need to buy
K20A2 Crank Pulley
K20A2 Alternator (no use K24)
K20A2 Thermo housing
K20A2 Starter (no use K24)
K20A2 Oil pan, pump and chain guide
K20A2 oil cooler (no need, K24A3 already have)
K20A2 water pump (no use K24 because is smaller)
K20A2 Starter (no use K24)
S2000 joint cooler,p art # 11107-pt2-000 (no need for fit oil cooler because K24A3 already have)
K20A2 Crank baffle (this? http://t2.gstatic.com/images?q=tbn:ANd9GcSGxXekyIp9SQIvWqW6GFCXjVKLr6ZsU4Uakyk34h119y2o3QIB&t=1
if i put k20a2 oil pump i need put also his crank baffle? i cannot fit the pump with no crank baffle or
K24 crank baffle?)
NUMBER 4=WATER PUMP AND OIL COOLER tell me please if what i write is correct or not. write OK or NOT OK and what u suggest
We already said that K24A3 have oil cooler, so no neeb work on it.
It's better fit K20A2 water pump because is bigger than K24A3.
After that remains only to connect the two hoses.
Water pump and hoses fit bolt on

NUMBER 5=OIL PUMP
take out K24 oil pump

http://image.hondatuningmagazine.co...htup_0511_04_o+k24_engine_block_k20_cylinder_head_build+oil_pickup_assembly.jpg

modify and fit k20a2 oil pump, k20a2 chain and chain tensioner

http://img830.imageshack.us/img830/3941/qweac.jpg

Important: with k20a2 oil pump, tapping oil orifice.
WHY ON MY FIRST POST SAY TAPPING ONLY ONE AND ONLY THAT OIL OREFICE
http://img88.imageshack.us/img88/2992/oneec.jpg

BUT HERE SAY TAPPING TWO OIL OREFICES? CAN U READ AND EXPLAIN ME? maybe because he do another kind of modify? LOOK

how many and which oil orefice i need to tap?

NUMBER 6= CRANK BUFFLE
Tell me everything about it please. I don’t know what is it. I only know it need from K20A2

NUMBER 7= CRANK PULLEY
Need K20A2 one, right? Which tensioner I use?

NUMBER 8= EXHAUST HEADERS HONDA CIVIC HB 93
any headers for Kswap are good?

NUMBER 12A=AXELS
Which ones?
-hybrid racing K swap axels? other brands?
-external joint Bserie; axle K20/K24; internal joint K24/20 (if K24 int.shaft/if K20 int.shaft; OR INTERNAL K20 JOINT IS SAME K24?)
I say this "hybridation" because here in italy, we have civic hb 93, with k20a engine. The owner sais that only with Hasport mounts the best axels are: external joint from Bserie,axle, internale joint and int. shaft from K serie (dc5).
With this setup it run over 30.000km and no any trouble. With hybrid racing mounts, this combination NO WORK

NUMBER 13=POWER STERRING
im in doubt about put an electric power sterring pump.
Example: K20A from DC5 has a mechanic p/s pump. The problem when we fit the motor inside the civic hb, is that the pulley hit on the hood. For clear the problem we have two ways:
1- put an electric p/s pump
2- put an Adjustable Pulley Kit, same this but for K24 (i never look if is on sale on the web swap shop). What do u think?

I say this "hybridation" because here in italy, we have civic hb 93, with k20a engine. The owner sais that only with Hasport mounts the best axels are: external joint from Bserie,axle, internale joint and int. shaft from K serie (dc5).
With this setup it run over 30.000km and no any trouble. With hybrid racing mounts, this combination NO WORK
Do you use the Hasport engine mounts? If you use Hasport mounts you can use 'hybridation' mounts with B-series external joint and DC5 internal.
You can also use DSS 2.9

NUMBER 13=POWER STERRING
im in doubt about put an electric power sterring pump.
Example: K20A from DC5 has a mechanic p/s pump. The problem when we fit the motor inside the civic hb, is that the pulley hit on the hood. For clear the problem we have two ways:
1- put an electric p/s pump
2- put an Adjustable Pulley Kit, same this but for K24 (i never look if is on sale on the web swap shop). What do u think?
(http://www.k-tuned.com/store/product_info.php?products_id=142)
You can use the K-tuned product if you do not want power steering :up:

NUMBER 16=HP AND TORQUE
With this simple set up of only OEM parts, which values I can reach?

Power will depend on a lot of things. If you have a good header, and good tuner for K-pro ECU then maybe 230 WHP, 175 WTQ. With good camshaft more power. With ITB more power. For beginning engine, I say keep it simple

I no want boring u, but i need quote again this list.
You say just leave stock for now, so for soft setup i no need to change anything. Now i would understand which parts never need to buy, and which parts are necessary for upgrade or because they work better.
Look what i mark on the list, and if u know, finish to complete it

NUMBER 3=OTHER COMPONENTS

K20A2 Crank Pulley ---> NEVER NEED/NEED FOR IMPROVE-IS BETTER

Yeah, you will need a good header/exhaust. 70-80mm exhaust on car, like for turbo engine.

Cams are good too. IPS KME cams :up: Great power for stock motor :up:

Get K20 intake gear, VTC system :up:

I don't know about the ECU from the K24A3. Is it in this list:
http://www.hondata.com/ecus.html

Wiring you might need K20 engine wire harness. Ask hondata, or hondata dealer in Italy, maybe they know?

Throttle body on the engine? Is it cable, like B-series engine, or electronic like new 2006 Civic?

thanks, no need change springs and drivetrain, great!

Get K20 intake gear, VTC system :up:
-K20 intake gear only if i buy IPS KME camshaft or any aftermarket camshaft? if i use the stock camshaft, i need or not get k20 gear/gears?
-only intake or also exhaust?

im looking for, but i think same u about the good one is from EP3. But i put Kpro on k20a2 ecu or k24a2 ecu?
For EP3 EUDM the name of ECU is PRA (K20a2)

Throttle body on the engine? Is it cable, like B-series engine, or electronic like new 2006 Civic?
im looking for, but i think is electronic, need check

yes, you will need new valve springs with those cams. You can buy that (cams and valve springs) later though, after you get the motor in the car and running :up:

Regarding the VTC, it is only the intake gear. It will be good with any cam :up:

You can only use the ECUs listed here
http://www.hondata.com/ecus.html
So, EP3 EUDM PRA will work, but, it does not have a wideband oxygen sensor nor support for nitrous. The USDM ECU is better. :up:

Re: first K24A3block+K20A2head from Italy. Be patient and help me step by step

The throttle body should be drive by wire, so he will need a cable throttle body.

When you engine shop just buy a complete engine. Believe me it's much easier, I bought just a bottom end and spend so far $500 in parts that were not there and nuts and bolts.

Keep it simple, complete engines come with everything except a starter and alternator.

Then buy the k20a2 oil pump, baffle, oil chain guide, oil chain tensioner. Standard k20 and k24 chain did NOT work for me on a k24a1 which has the flat deck on the lower cradle.

If the k24a3 lower cradle is identical to the k24a2 then the standard k20a2 chain should work, if it has a flat deck then you will need the chain with pcx in the part number.

And IMO you should go with an rsx type s ecu and kpro just to be safe.

manzoHCI · Apr 7, 2011

Re: first K24A3block+K20A2head from Italy. Be patient and help me step by step

1***Maybe my friend have intake and exhaust cam gears, so i think to buy and install both.
i know u told to me about ONLY intake for VTC, but if i have also exhaust cam gear K20 is better or no change nothing else?

Vee Easy said:

2***anyone can confirm that?
signalpuke,do u know or remember if the k24a3 lower cradle is identical to the k24a2?

3***For find the right o2 sensor i need to look:
which engine i have? --> which ecu can works with engine?-->which o2 sensor works with ecu?
is correct? sorry if i write something crazy but i dontk know nothing about ecu,wiring and senors

signalpuke said:

4***First of all, i find that Hondata doesn't support ecu of K24A3 EUDM
http://www.hondata.com/forum/viewtopic.php?t=8227&sid=6bb4647516ac4df02b0931c5e24cc337
and second i dont need nitrous.

5***Both prefer ecu usdm rsx type S, but i want move in this way, tell me what do u think:
-look for rsx type s ecu and ep3 ecu
-if the price difference is low, i buy rsx ecu
-if price difference is high and rsx type s ecu is so much expensive, i will buy ep3 ecu (my friend has already got kpro and he buy the wideband, so he can borrow it to me)

6***everybody speak about Kpro. What about K100? Big differences? Or i can also buy it for save some money? (it's cheaper than kpro)

7***for wiring harness if i no find ep3 wires, i will consider hybrid racing harness. i dont know if is plug&play, but maybe the big part of work is already done.........................

i dont understand what differences are from k24 wires and k20 wires and why maybe is better start with second one. however i must modify same for fit on k24?
and with k24 i should buy also his o2sensor?

The harness will match the ECU, that is usually the easiest way to make the swap work.

This way the ECU can talk to the engine sensors over native wiring path.

Most 'swap' harnesses are made for the K20 engine harness.

Best to ask your person that will do the wiring what they want to use.

I do not know if there are differences in the USDM/EUDM wiring

Re: first K24A3block+K20A2head from Italy. Be patient and help me step by step

The K20 exhaust cam gear is the same as the K24, you don't need it.

I think the lower cradle is the same. If it is different it will not be a problem, you will still need to modify the oil pump to fit on the motor.

ECU: You can use any of the ECUs that are on Hondata's website, but if you use one of the USDM ECUs you will need a new o2 sensor (2002-2004 RSX-S).
If you use the EUDM PRA ECU from the 02-05 EUDM Civic, then you will use that o2 sensor.

You will need to use an adapter harness between the K24A3 engine wire harness, and your car dash wire harness.

Does Hondata still sell the K100 in Europe? I think only K-pro now.

manzoHCI · Apr 8, 2011

Re: first K24A3block+K20A2head from Italy. Be patient and help me step by step

for the oil pump i know need modify. i ask about cradle for know this:
k24 cradle = k20a cradle: i can use k20oil chain,k20tensioner and k20guides

k24 cradle NOT= k20a cradle: which oil chain i use? k24tensioner and k24guides

about k100 maybe yes,maybe used,i need to check

Vee Easy · Apr 8, 2011

Re: first K24A3block+K20A2head from Italy. Be patient and help me step by step

Look after you get the engine remOve the oil pan and see if the lower deck is flat.

If it's flat NO need to modify pump, just install and get the oil pump chain with pcx in the part number.

Re: first K24A3block+K20A2head from Italy. Be patient and help me step by step
