i was lookin to buy this engine...the guy who owns it says the block says its a k20a2

but then i asked him to verify its the 200 hp and he said its the base model 165 rsx motor.


so my question is....is it possible that the k20a2 is the base rsx motor with the same engine code.

AND

What can I check visually to know if its the 200hp or 165 hp engine. on the block and the head so i know its not swapped

 

check for the engine code on the timing cover & ask to take pics with the valve cover off, it'll look more full with it's cams & rocker assembly

 

Got any pics of base vs type S so i know what i will be looking for? with the valve cover off

 

The base is the k20a3. Ask him to take a pic of the engine code with a piece of masking tape above it. Reason being its hard to find a pic of an engine code online with a piece of tape above the stamp. That would give you your answer right there. if he refuses its because hes lying and it says k20a3 , Or ask him to take a pic with his face next to the code, just so you know he isnt fkn you.

 

Good idea

So far i know that the a2 spark cover is much smaller than the a3 spark cover


Now that leads me to ask if the valve covers are interchangable between the a2 and a3.


Also, whats a visual difference on the blocks, besides the engine code.

 

and how would i know if its JDM based on visuals?

 

I dont think the JDM's had any numbers on the block actually. Also the jdm integras base motor had a black plastic intake manifold just like the base RSX here.

 

well that can be swapped easily

 

dude, the guy apparently said its the base model engine

why would he lie and tell you its the weaker engine? that wouldnt tempt people to want to buy it more..

he is prolly telling the truth

Exactly thats why I said its probably a K20a 3

 

thats what i thought. but i asked him twice specifically if the block says a2 or a3 and every time he says a2.

I think he might just be a moron.

On the a3, someone said that only the intake cam has vtec and not the exhaust...true?

Yes.

Go do some research on the k20a3.

 

I would #1) Check the block code, that should pretty much sum it up right there.

If u cant check this in person, dont buy the engine.

#2 Check the engine #, this will also tell u what kind of engine it is.


Biggest advice I can give.... Dont buy this engine, nor any engine, without seeing it.

 

Wheres the "engine number" and how do i check this against something

I am going to look at the motor in a few days, but i want to know what to look for before i go.

 

The engine code should be under the drivers side of the intake manifold right underneath the throttle body...its kind of in a weird spot you should be able to see it clearly if your in the right angle.

alright, what am i supposed to look at. the number yes, but how will i know what that number means. unless ur talkin about the block number

 

everyone is right... probably a k20a3 with 160hp, but if you really want to know take off the head and check out the cams.. type-s cams arent interchangeable between the base and type-s

You might want to go double check that. Its been done before.

Anyhow check the block code. Done.

Here are some pics showing the a2 and a3 heads ... the differences are very clear! Intake side toward bottom of page ...

Enjoy

K20A2 - RSX Type-S


K20A3 - Si, Base RSX

 

is the picture in the or the motor in the car?? if so the Intake manifold should be black and look like 2 runners a space and then the other 2 runners. the K20A2 has a bigger space in between the manifold runners

Already stated I believe. Not to mention that is something fairly easy to change out, for the sake of fooling someone into thinking its a k20a2.

Anyhow like I said before, the guy is probably confused on the block. Its probably just a k20a3.
