just curious about swaps

[new2teg]

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! 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?

[new2teg]

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

[Vvvtec]

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

[vtecing]

what is this 'real' vtec you speak of?

[new2teg]

what is this 'real' vtec you speak of?

the difference between performance vtec and economic vtec

[new2teg]

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

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

[TheSaint]

isnt the K24a3 also economy vtec?

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?

[GSi_PSi]

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

[TheSaint]

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