Grateful to have seen this video, badass information. I wanna put a k20z3 head on my k20a3 and I was worried about the oil pump and whether or not I'd have to get a type s oil pump or if I can get still use the a3 oil pump

[@Kaohteeko]

I’m looking to do the same thing. K20Z3/A3 on the EP3!

great video bro 🤜🤛💯

I just pulled a oil pump from a k20a3 mine looked brand new remember to also take the bolts that come with the pump an the windage tray with all the 10mm bolts i forgot the chain for the pump but ill just buy a new one for peace of mind. I only paid $26.00 US dollars for it

[@johnnystoka6625]

What about the pressure relief valve spring tension .

Great video, saves a good bit of research. I went from a dc5 k20a3 to a k24, took the oil pump from the dc5 k20a3 as it was still in good condition. Port/Polished with the washer mod. Almost 10,000km later, still going strong. I do wonder if I could slap on the stock k24 oil pump onto the k20a3, since it'd be like recreating the EP3 k20a3 engines. (They had similar pumps)

[@Streetk20]

I don’t see why not however the k24 style pump is fairly undesirable

[@Streetk20]

And thank you, I myself had struggled to find info so figured I’d share it I do feel I could have made the video a bit more informative and what not but hey I’m only new 😂

@@Streetk20 oh haha, it's so it becomes a usable engine again xD.

[@djdocdman]

@@Streetk20 nah you're alright, saved someone an hour of researching on different forums and compiled it into a short video. Goes a long way!

[@Streetk20]

@@djdocdman in that case if you use the appropriate oil pump parts I.e chains ect then yeah should work

[@colecampagna6302]

Does the k20a base have the better oil pump as well?

[@ronaldmeira1552]

Normal the by pass piston spring has little more pressure

[@codeisland8015]

I changed the pump on my k20z3 to this used k20a3 pump. Got all hardware needed along for the swap, while on the dyno it spun a bearing while getting tuned. Could it be because the Oil pump. The only other mod was dc 3.2 cams with valves and retainers.

[@Streetk20]

Sorry to hear that man, no one deserves that to happen however In all honesty it could be a number of things, even as simple as a clogged pick up or if the car has had a sketchy service record before you it could have a clogged journal ect you will have to tear it down to get a better idea of what happened. If the motor came with the balance shaft style oil pump it probably needed a hole plugged as if it’s not then you wont have very good oil pressure, the oil pumps a3 and type s are a fairly basic design not a lot can go wrong with them so I would be assuming other reasons

[@adrianvega4817]

yes

[@alitoroganan2442]

Bro can you compare the crankshaft aswell, cheers

[@oscarjsm24]

Does this mean the ep3 have a “type s pump” too?

[@Streetk20]

If it looks the same as these two then yes

[@mprism7985]

No ep3 has a balancer oil pump only the rsx has this oil pump

[@Streetk20]

@@mprism7985 depending what part of the work you are in, pretty sure ep3 type r will have this pump.

[@mayk3lll]

Do these two pumps have different part no.s??

[@Streetk20]

Fair question I will try and get back to you when or if I find the appropriate answer

[@mayk3lll]

@@Streetk20 appreciate that

[@DavidBaileyloveICE]

Yes because they are not the same! This is a great video I love the Honda community but this information is incorrect the A3 pump is not the same as the A2 pump.

[@rushane1707]

The part number is the same

Is it the same oil pump ?

Thanks for the info but just a pro tip: nobody wants the intermission audio to be 4x louder than your voice. Please, normalize that useless audio.

I wasn’t aware it was like that sorry it seemed normal on final run through before upload
