How to port and shim K20 Type S Oil Pump

In this video, I port my k20 oil pump so it can flow better and also so it wont cavitate at high rpm. I also shimmed the oil pump spring to bump up oil pressure. If you find the video helpful please like the video and leave a comment! Dont forget to subscribe to stay updated on the build!

might do this

Vaseline works great prime your oil pump when you put it back together

I’m gonna try this on my h22a wen it comes time to build it

Differnt style pump for the h

What was the thickness of the washer under the spring?

[@A.QPerformance]

I am gonna try it on a k24 oil pump.1st i am gonna cut the balance shafts and than port

[@sleeperworksgarage]

That would be dope if that works. I have so many k24 pumps laying around.

[@francastro1985]

👍🏼good info, wondering which crankshaft sprocket did you use? having trouble getting the chain on....any advise? thanx... i have k20z3 head and k24a2 bottom end.

[@sleeperworksgarage]

I'm using the k24 sprocket. Even with k20 head swap you want to use the k24 crank sprocket and trigger.

[@francastro1985]

@@sleeperworksgarage same here...pump is already modded for the k24. i replaced the chains n guides on my k20z3 awhile ago. im test fitting the OP chain i didnt use. still no luck...

[@sleeperworksgarage]

@@francastro1985 are you trying to install the chain after installing the pump? You have to install the chain and pump at the same time or itll never go on. You have to angle the pump get it under the chain then mount it to the block. No guides no tensioner. Just the k20 pump the k20 chain and the k24 sprocket. Then after you get it mounted up install the k20 op chain guide and the tensioner.

[@francastro1985]

@@sleeperworksgarage thanx for the info, i really appreciate it.!.!.! i think it might be a link too short. i read reviews on the timing chains kit i bought. turns out that the OP chain was made like that be mistake.

[@A.QPerformance]

@@francastro1985 yeah k24 chain is 62 links and type s/r oil pumps have 64 links.so when using k20 oil pumps on k24,you have to use k20 chain,guide,tensioner and baffle

[@raton5936]

I'm currently rebuilding my stock motor with future plans of going higher rpms. Would doing this now be a bad idea?

[@sleeperworksgarage]

No doing this will increase your oil pressure allowing for better lubrication at higher rpms.

[@davidmachado3987]

Is the baffle tray and screws also from the RSX base? Or am i pulling out only the pump if i find one?

[@sleeperworksgarage]

I got everything out of a base model.

[@davidmachado3987]

@@sleeperworksgarage thanks for the info. I didn't know they used the same pump.

[@sleeperworksgarage]

@@davidmachado3987 Right! When I pulled the pan I was like 👀👀

[@alomechanthasinh4079]

Was gonna ask the same question. Now I know.

[@djmlover]

I need one , can you please tell me where can I find one and for how much, I’m also planning on buying a k24 for my 1999 crv 5 peed, thanks

[@sleeperworksgarage]

Online the oil pumps are running $200+. if you find a k20a3 in the junkyard grab the oil pump from that it's the same as type s.

[@djmlover]

@@sleeperworksgarage I want the same one you have, which brand you recommend? I just want to buy and spend one time on good quality parts, I appreciate it

[@sleeperworksgarage]

@Dj MLover I grabbed mine from the junkyard from a k20a3 and ported it myself. A ported oil pump is going to cost around $350 not including the other parts you need for the conversion. I recommend getting an OEM oil pump and having it ported and shimmed or buying an already ported pump. There are a few companies that offer ported k series oil pumps.

[@thedude3189]

How thin is too thin for porting? Yours looks thin as well on the corner towards you if your looking at it. I just ported mine like yours...did yours hold up? I'm scared to install mine now.

[@sleeperworksgarage]

Not sure exactly. I didnt take very much material off at all, it may have looked like that on camera (I am using a cell phone). My engine hasnt been run yet it's still on the engine stand. Also you are doing something like this at your own risk. If you feel like you shouldnt run it then dont. There are companies that offer professional porting services for our applications.

[@thedude3189]

@@sleeperworksgarage I've been porting for 5 years now various heads and throttle bodies and my 3rd k24 build, did a poor man's type r as well b18c1 b16 head, Frankenstein d16z6 y7 build and a couple 4runner 3.0s, only my 2nd oil pump i ported that's why I was just asking because I just seen you do it lol. I've seen other professionals fuck up all the time on simple stuff and ugly work, online pre ported bolt ons I've seen crooked and half assed. I ported it less thin than yours, you took out more material than I did so I'd be iffy on running your pump, so I don't know if I shouldn't run it because like I've stated i don't know how thin is too thin, I can send you pics it looks like it came from factory all my work does, regardless why would I have someone else port it even more???

[@sleeperworksgarage]

@@thedude3189 lol I'm not saying you couldnt do it. But that there are companies that offer the service that are reputable. I also meant to start with a not ported one and have it sent out not to continue porting the one you have. I watched someone else port theirs and mimicked theirs and they run some pretty big power engines. I do plan on checking oil pressure manually when I turn it on for the first time. Just havent gotten to that part yet. I'm all for trying it at least, if it doesnt work I'll just throw a stock pump in. I'm pretty confident itll be fine tho.

[@delectronics118]

@@sleeperworksgarage hi man, do you have any updates on that?:D I am curious if you are still on ported one and if you gained some psi Thx✌

[@wickedsatan1]

Putting shim is something new for me, whats the purpose?

[@sleeperworksgarage]

It's supposed to help bump up oil pressure.

[@luisrank11]

Is it ok to reuse oil pumps?

[@sleeperworksgarage]

Absolutely just have to make sure the tolerances are within spec!!

[@Jaguair55]

Does a little pointing honestly make a big difference though? Real question

[@sleeperworksgarage]

Yea it's moves a lot more oil. Assuming your talking about porting.

[@Jaguair55]

Yes thank you. Also do you have videos on k series trans modifications like dogbox install?

[@sleeperworksgarage]

@@Jaguair55 No I'm not at that level yet. 😅

[@Jaguair55]

Thanks bro keep posting good shit.
