Does anyone know what it would take to convert a base RSX/SiR K20C to the Type S K20A? Is it just a matter of switching heads or is it a complete engine swap? Might be the deciding factor in getting the new Civic Si/SiR...

 

base rsx = k20a3
type s = k20a2

Type s has more compression (pistons), as well as head differences. vtec is also different, but i think vtc is the same, so pullies may all line up. also tranny..

 

There's no such thing as a K20C. People just assume that because the old TYpe-R was a B18C, the new Type-R is a K20C. It's a new series of engine with new engine code.

 

just to add, the type-s tranny will only fit on the type-s...same with the R...S owners can't take a R tranny and just bolt it on without some modifications...you can find a lot more about this at clubrsx.com

 

add a 100 shot

 

this is news to me.
can you tell me why?

 

Sorry,my bad, I thought I read K20C somewhere. Either way, it looks like a whole longblock/tranny swap is the easiest if not the cheapest (excpet for nawsss LOL). Thanks guys.

 

Just drove the new SiR yesterday and looks like I'm keeping my EK. What a letdown! Is the RSX any better? I'm sure the Type S is.

 

i like it.. handles well, specially with the hockey puck tires.. did a little 4 wheel drift last nite.

decent power too..

 

Would a k20 S2000 head fit on the RSX-S block? What are the differences between the RSX-S longblock and the S2K longblock? Will the RSX-S tranny bolt to S2K K20?

Just pondering swap options...

 

dont think the heads/blocks line up properly.

trannies - im not sure, but im guessing no. this is why the k24 swap seems to be the way to go..

 

what he said...lol...
oh but to answer the question about why the DC5-R tranny won't fit on the type-s is because the housings are different...so like i said, you would have to modify a bit...now the FD will work and so will the flywheel...but i would still like to see someone try it...

 

Dude where are you getting this crap? making it up as you go along?
It bolts right on You don't modify anything. Its the same block in both cars just different pistons cams and a few other parts.

 

yes moron the blocks are the same, but the trannys are not...let me ask you this...have you tried it yet...exactly...just as i thought...i'm not making this **** up, this is legit info from someone who has the specs on both trannys...maybe you should do a little more research before you try to clown someone...

 

I'm sorry I came off a bit hard. I just hate to see misinformation.
The tranny cases are the same, Case in fact why you can bolt either to the USDM or JDM block and also why you can add the JDM LSD or gearing to the USDM tranny.

 

i'm gonna have to search for the info again, but i am almost positive that the cases are different for the type-r's...oh and sorry about the moron comment...

 

--------------------------------------------------------------------------------

is there any ready kit to connect the s2000 trans to k motors or even others if possible, also is there any other stuff to be used to fix those front wheel engins vertically in the car

 

why do u keep bumping threads from 6 years ago...these people are most likely not around to answer ur questions...go to www.k20a.org

 

You my friend are the epitome of the word "NOOB".

 

Ummmmm. Depending on the year thats true but even the k20a3 can have a k20a or a2 as a direct swap in no modification needed.

 

im not completely sure about the tranny stuff but im sure the the k20z1 cant use a k20a tranny, i found on jdmland.com that they were selling a itr tranny but it only fit on the k20a2 and k20a3 but not on the k20z1 which is the '05 and '06 type-s

 

thats what i figured too that the z1 was different cause i have heard its a bitch to swap anyway

 

Talk about back in the PAST!!!!!!!!!! lol

 

You are bad wrong. All the K manual trannys will bolt up to the motor but some trannys have a different chassis mount( Accords, TSX, FGs)

 

Dude this thread is from 6 years ago! lol
