What helps flow efficiency, increase good oil pressure psi that doesn't necessarily rob power due to increased windage
We discuss the blueprinting mods we do that lets you improve oil pressure without the need for running too thick of an oil
Also we touch up on a common misconception on shimming and what not
and why side clearances matter on the oil pump gears
as mentioned Episode 1 of the d16y8 build series with dyno is here

knowledge is power 💪
good job Ralph and thanks for sharing 👍
Thaaaanks Doc! definitely fun sharing what got me addicted to engine builds and design lol (hawa hawa na to lol)
This is something I never thought about, I knew people would put a washer to shim the pump to increase oil pressure by a lot but I didn't know that was actually a bad thing, no wonder 4piston racing don't do this, they port the pump instead which makes sense. So in conclusion porting the oil pump is a much wiser decision than shimming it but the thing is not everyone knows how to port the oil pump and an easier way more is just to add a few washers and get 100 psi of oil pressure 😅 happy to know this knowledge, I appreciate it, great video
So true on ur observation
And it’s also why I talked more about the “sideplay” of gears cuz porting is not as easy either
Thanks man for checking this out!
@@SRDmotorsports So true, I love how you're detailed, you're welcome man
@@StraightOutThaGudda4U just don’t forget to have fun with family this holidays man… and watch my vids hahahahaha
@@SRDmotorsports 😂 I've been playing catch up with your vids cause i haven't gotten time to be on TH-cam that much but I am surely gonna watch the rest I missed out including your latest one haha I've spent good time with the family and I hope you do too and put the wrenches down for a bit 😅
@@StraightOutThaGudda4U yes sir RN I’m hiding from food we gotta stay healthy hahaha they always after me (the food lol)
Great vid as always! 👍
Thanks brother! :)
Looks like i am going to be purchasing a new pump to send to u all the way from NY USA
Oh ftw man! Is it a Bseries pump?
This is mandatory always, good oil pressure key 😎👈
Oh yes sir!!!!! Yes sir!
Come to think of it… it’s only now I have ever announced or declared it that it’s ALWAYS part of our “rebuild labor” since day one… well I guess we were always no good at salestalk 🤣😂🤣
I have an ACL Brand B20 Oil Pump Sitting in a box collecting dust probably should put it in my B20B even though the one that’s in my old b20 on the floor has a only a few miles on it so might throw it in since it’s never used ...
That’s a good pump indeed
Muito bom os teus vídeos. Abraço de Portugal
Oy! Obrigadisimo’ 😂 obrigado meu amigo… saudades de Philippines 😎
a lot of guys would benefit from this..including me.
locally to us? Definitely! even the sohc peeps…
Even made a trivia-style comment on the shop page where I posted ftw!!
Super interesting! What are your thoughts on the Toda Racing oil pump gear?
It’s good but very overkill on a street motor
2jz oil pump have a straight shot and turn 90 degree’s exactly like this. One mod those guys do that really increases oil pressure is close off the motor feed and weld a fitting where that straight shot is, from there use a hose into the motor and feed oil that way.
That less aggressive turn (using a hose) will increase pump performance allot. some supra guys even get too much pressure that way.
Oh yes! Angled turns really kill a lot of flow and pressure it’s why most AN fittings are curved pipes that’s superior
Hi Mate, for a Street d16 that will see occasional public circuit days, do you reccomend a stock pump with the works described in this video, or would you reccomend something like an ACL pump if it can be afforded and some extra clearance bearings. Thanks heaps !
I think if the stock pump is inspected like on this video and it seems good and possible to refresh then I say no need to buy another
🔥🔥🔥👌
Saving $ when possible ftw!
Hello sir
Didn’t know you from mozi sections 😬
Next to SA my friend 👌🏼🤓
Anyways thanks for the very informative video as always 😎
My honda had lost oil pressure i the week and I tested it today only to find out I am getting no oil pressure at all from the Vtec test port or from the oil pressure switch,
I hope I didn’t cause too much damage to my bearings.
I had done the shim mod as well as it had increased the oil but didn’t know it would be a bad mod in the long run,
Thanks for the articles explaining why we shouldn’t add the shim
Are all b series oil pumps the same?
Yes I grew up in Maputo so almost every month we drove to Nelspruit so I enjoyed “Steers” I love food haha
most of the Bseries pumps are the same or atleast fits among each other but the b16 and b18c pump are the better ones than the b20/b18
But personally the b20/b18b is fine if the engine is built good and well so it is okay I use a lot of those
@@SRDmotorsports he he
Must hit me up with a message when you come this side again
I’ll take you to some restaurants where they sell real good food 😁
Thanks sir, I am trying to get another honda b16a pump, will most probably have to order form honda
Oh yes will def hit u guys up when I’m in the area once again
Greetings from Portugal :) nice to know you speak Portuguese as well
I'm kind of confused here...
I have a b16a2 pump and a b18c4 pump from an mb6 civic (ukdm) but the b16 pump gears are in fact a little bit bigger than the b18. I noticed it when I tried to switch gears between pumps and the b16 gears won't fit in the b18 pump housing so maybe it is an aftermarket pump gear with a modified housing?
Now I'm rebuilding the b18c4 but the pump is in really bad condition compared to the b16 I have
My question is if there is any difference between b16 and b18 pumps regarding oil pressure and flow? Presuming they are both stock
Greetings man! :)
the pressure difference should be minor,
on both oil pump u should see a “number”
Engraved on the outer cover the one that faces the back of the pulley when the pulley is installed ? The higher number was sought after… like a 9-10 or 11 was preferred than a 7 or 8
I think cryo and wpc coating the gears would help.
Oh definitely on the WPC for sure
Obrigado, Growing up in Moz!
Whoaaa nice!! We lived in Maputo by Somersheild that’s so cool!
@@SRDmotorsports Sorry😅Correction, I never grew up in Moz, rather a school Friend did. Great channel, good logical advice.
@@graemedicks3139 oooh nice bet he or she a funny person too that’s what Moz does 🤣😂🤣
@@SRDmotorsports 😀She is, dry humour good at, mathmatics and ...cooking.
@@graemedicks3139 it must be the chicken in moz hahahaha I swear haha
What about a h22a4 oil pump? Im about to do mine and am curious about it. Ill examine it amd see if there is anything that i can recognize from your explanations, but would there be anything in particular?
They’re actually “visually” similar to the Bseries
not sure if I worded it well enough back in that vid but the “cover”’or back side usually gets worn vs the steel gears and more sideplay there eats up pressure and oddly enough accelerates cavitation or in essence makes it happen sooner or worst so the almost no sideplay is always better…
Almost always it’s the back cover that gets worn cuz that’s aluminum, unlike the steel gear
(This something that’s easy for you to do actually)
Does the "back plate" wear more than the main housing? Also, are any of the aftermarket B series vtec pumps any good?
sometimes… and even if the main housing gets worn it’s harder to resurface it and so the backplate atleast reconditions “half” of it
The ACL ones I’ve seen and held one is mint actually
@@SRDmotorsports Since the oil pump is running all the time, what is a mileage interval to check or recondition the pump?
@@TrackSol that’s a good question but quite hard to tell I mean… it also has the gears submerged in oil, but locally anything that’s over 90,000km in the odometer I def check even the last series the VTi while not worn it did benefit from blueprinting it hence u see on start up before it even runs as we crank it oil light turns off ftw
What about drilling dimples into the gears so they capture additional oil and lubricate better? This is common in american muscle LS builds. Just wondering if can also be done
That’s quite possible, but I haven’t tried it myself
@@SRDmotorsportstry it out
Yep one day
Do you do this service? Alot of the shops around my way just throw our engines together most of the time
On oil pumps yep on most or almost all our rebuilds… because people sell oil pumps like it’s gold and I can understand it’s not always that the customer has an open budget
Oil pump no 10 good for b20b or standart b16a
🔥
😎👈🎯🙏
You know you got this ftw!
How about K series Type R and Type S pumps? Toda Racing actually shims and recommends shimming the K pump. One would had thought Toda being a big company involved in Honda tuning for decades and has their own R&D and manufacturing, would had know better?
No actually on the K series it might be different and I haven’t researched as much on that yet mainly cuz on k24 ? Upgrading to k20 TypeR pump solves a lot including cavitation and even better on s2k pumps…. it might be different in a sense that the oil pump is belt driven? I know some brands offer some mods that slows the rpm of the oilpump thus moving the cavitation limit higher or away from normal rpm reach hence shimming might be an effective safety margin
Toda is the real deal so they for sure got some good r&d on that hence I consciously didn’t include the K stuff , until I got 101% research 😎
@@SRDmotorsports Thank you so much for the thoughts, yes K oil pump motors are chain driven, not sure how it differs in this sense, but if you look at Toda products under their K series oil pump/balancer shaft delete kits, they mentioned they increased the spring pressure by 15%. In another old instruction sheet from Toda about upgrading the lower block, they recommend, shimming the K oil pump with 2.5mm thickness worth of washers. The K pump's valve likewise relief back into the pump path within the pump, instead of outside the pump and into the oil pan, but I wonder if the valve internal design is the same and if shimming will actually reduce the 'supercharged' oil flow for the K pump motor. Would you investigate further if you have the chance next time for a K pump porting project or something?
@@antonc108 thank you for the added details now I can sense where we are (as far as discussion) goes
And yes I will want to definitely look into it
And it may be a lot more reasons example maybe too Hi psi can do harm on oiling of the cams and head itself… but yeah thank you for this as it adds more ideas for future content
We are currently (but no rush so slow build) a k24 that will have a TypeR oil pump and a k20a that will have an s2k oil pump so definitely this adds good ideas on the research and analysis
@@SRDmotorsports Thank you sir, please discuss baffled oil pans while on the way too!
Thought you've gone on vacation! The channel's been silent haha
No hahaha just didn’t have a Friday release as u noticed it either for a series or car review style kaso wala na eh but Tuesday is mostly Tech Tuesday ftw haha
@@SRDmotorsports Totally understand, it's time consuming to edit videos buti nasisingit mo sa schedule -- I tried doing a personal project once, it was ok but then I messed up the final edit. 🤣
@@findtherightbeat oh u have no idea ilan mess ups I did on final edits way back, I think as humans we learn and adapt? Nowadays it’s not easy but it’s not hard na… like I got used to it by Saturday (latest Sunday) the tuesday vid should be done and inde Monday starts? The Friday vid starts and by Wednesday night done editing… so now lack of content means lack of projects or series hahaha
Still fishing out for (hopefully) an SiR locally or even a CRV rd1 to do the same style series with baserun , personally I’m hella curious on a baserun of an siR then a final run after rebuild lol!! Even a crv!!!
@@SRDmotorsports Nasakto mo, it's not hard but it takes time. Hope your channel grows more over the year, it would be nice if you share 4A projects you did in the past para mag-expand din viewership sa ibang makes.
What measures of mm resurface will do enough to smoothen the oil pump cover? And give more better oil pressure? 🤔 Or secret? Just sends the oil pump to you guys🤣
usually even less than 0.010” = less than 0.25mm anything deeper means more worn pump still rebuildable but not as good
Both those oil pumps you have there are for a non vtec LS. There is so much BS misinformation on youtubevits stupid. If you want the best performing Honda b series oil pump buy a brand new Honda B16 OEM pn# 15100-P72-A01 oil pump, then send it to 4P Piston Racing to be properly ported.
Yep that’s the vtec oil pump that’s good and I agree easier for the US guys to go 4p on this and they do it right and properly too! as always
Love your videos .. very insightful...and learning a boat load.
Do you by any chance have insta.. would love to ask you some questions.
Oh thank you man!
Yep yep! Mentioned you on one of the community posts about it hehe
@@SRDmotorsports thanks I really appreciate it 🙏
