just curious about swaps

hi guys

im just curious (way too broke and noobish atm) since i saw that jdmyard thread selling k24a3's for cheap and was wondering what would be involved in a swap into a base dc5.

can you keep stock base dc5 ecu or need the stock accord one or go aftermarket?

can you keep base 5sp manual transmission?

is it a straight bolt on, like remove the 20a3 and put the 24a3 in a press go lol?

are there heaps of extra parts needed or would you have most of them having a dc5 already?

is it legal? would you need engineers cert?

i know it might be a dumb question but im just interested! :confused: would like to learn more about what i sit in most days!

cheers

im pretty sure you'll need a K-Pro, and you can run your 5 speed box.

whats the difference between base model K20a3 head and the accord K24a3 head?
any performance gain to be had by keeping the k20a3 head and putting it on the k24a3 block?

.4 ltrs? and correct me if i'm wrong but 'real' vtec?

Yup, k24a3 has 'real' i-Vtec, as well as the 2.4 displacement. Massive gains to be had by swapping the K24 with the K20a3

what is this 'real' vtec you speak of?

so for gains its a good swap? already having a k series would make the job cheaper/easier no?

isnt the K24a3 also economy vtec?

the base model integra has ...

K20a3

so do any of them have performance orientated vtec ... or are they all economy - and do some have better flowing heads / cam profiles than others?

the k24a3 has vtec on both intake and exhaust sides, doesnt use a plastic manifold. etc the k20a3 from australia not USA has like 117kw

Buying the motor is one thing. Get it all working and running right is another. There is a few things you need to make it all work

iv only driven the K24a4 .. that thing was a pile of poo =/

well from what i know....all the k series will have the same mounts(which also applies to B series etc so on)...so basicly it will bolt on. about the ecu...not to sure...pretty sure you can just hook it up with the stock ecu..for better performances ofc...k-pro upgrade. i hope this is helpful..or if i'm wrong...correct me plz :D

thanks for the reply's guys! i found this site with some info on the k series here and more in depth on the k24 series here

i really dont know to much about this so thanks all for helping me learn more :D

...just google what you want to know, you'll be suprised how much info you'll get.

oh i've been googling quite a bit I just wanted to start a bit of a discussion about it. I found loads of info on k series swaps in general and going from b series to k but not much on what i'm thinking of doing which is into my dc5 well actually there is a 'how to' on clubrsx for swapping a k24a2 into a dc5...

according to most American sites their k24a2 is ver similer to our k24a3 but the figures im seeing for the a3 are not very consistent as jdmyard in sydney are selling them stating they are 147KW and from wikipedia quoted before says their 140KW so... i dunno lol

and every time i think i've confirmed that the k24a3 has vtec and is at least 140 + KW then i find a site like here which says its only 119kw...

easiest way to go about it would be to get the K24a3 and than put a type-s/r k20 head on it and tune it - that way you will be sure that its going to kick ass lol

EDIT - also i would trust yonas at jdmyard over and american website - he knows his sh!t

yeh i've heard good things about jdmyard though the thread selling the engines was from a while back but as i said im just playing with the idea, not even sure if the dc5 is a good base to start with...

from my reading a k24a3 with a k20 head on it is sometimes called a "frankenstein" build i think and can get you well into 230bhp... nice.

i just need more knowledge or friends with knowledge (or just friends lol) and moneys!

there are several versions of K24 on the market. The most common K24A we come across here in Australia is the CRVK24A and EUROK24A

Now, the CRV K24A2 is pretty must useless with 160hp. Most people will swap the head out for a K20a head. What you really want is the Australian spec Accord Euro K24A3 with 200hp (140+kw), the head flows very similar to K20A counterpart and produce easy 140+kw AT THE WHEEL on dyno with I/H/E and KPRO tuned. We have a stock Euro K24a3 on our EGK24A and it ran high 11s down the 1/4.

nice thanks for chiming in with that, honda seems to reuse the same engine codes in different countries i think which make researching a pain. what started me thinking this is seeing the ones you had on sale last year in my head im picturing a fairly stock setup just something a little different you know

i also read the swap cant be done without kpro? their pretty expensive and to get that for a base manual i wont see any benifits till swap?

thanks for the replys!

Everything will bolt up, all you gotta do is get a better intake manifold for the K24 and tune it with K pro.

you might need to get it engineered tho to drive it legally.

It's that EASY.

everything is illegal in Australia.... even you stock Type R Recaro :p

...whats on your mind new2teg??? Are you thinking of doing an engine swap???

hmm, I was more curious I suppose. I don't really have the money just wanted to see how possible it would be, but I'd like to do it myself, if I had the skills :( lol maybe one day...
