- We show and share how we rework and develop the ports of a CRV nonvtec P75 head that let us see achievements of excellent performance and efficiency to boot! 15km to a liter or 35mp on city driving was the more common instances for our old friend's CRV that was for utilitarian use and a family car at the same time! That prolly did a job well done right?
Now on your civic imagine? it could be more efficient and perform better than as if it was on a CRV yeah?
We also give a shout out to Mugen and Toda on their famous Formula 3 engines which were Non Vtec B20 engines and we do talk about exhaust systems and its efficiency

Forgot to say! Comment down below if YOU have seen a “siento bente” or “120” on the road or around town 😂
Bro why do you gotta be so far wish you could build my b20v
@@Richie.em1 oh man I’d bet DHL happy for us? 😀 but where ya from? I got friends in Minnesota and they’re the only guys I talk to when it comes to engine ideas and innovation and really some I learned from them just they got kids so no time to make a channel but they got a Page though
@@SRDmotorsports im in florida there are people here but just watching your videos i like your work
@@Richie.em1 ah makes sense yeah well I guess even if we made the world flat like Kyrie its still far 😀
@@SRDmotorsports yeah bro love your work ima have to start practicing it would keep the cost on my b20v build and make it a lil cheaper if i do everything on my own and dont have to wait for Who knows how Long in a shop
My dad is loving this , and he said 4 piston is definitely watching your info 👌🛠🛠🛠❤🙏
oh maaaan too kind words but shhhh some are "sensitive" 🤣
I swear this guy has the hidden gems on how to build your honda in cool ways
maaaan thanks for that brother’ but now that got me “hungry” for something with extra cheese 😅
Was curious on what your content might be, and it didnt dissapoint!! This is on point!! 👍
Hey thanks for checking this out! :)
so much details and info learned from this brother. "stop sounding like a fool"" vtec kicked in yo
“Vtec all the time” ? Bruh hahahaha
Solid knowledge sir! Trying to see If I can practice this with my engine soon. hehe
If you are local all this is meant to show we are a legit shop vs an “all talk” “all claim” shop 😀 so for your future Honda stuff or any brand you can always bring it to the shop ftw
@@SRDmotorsports where is your shop located sir? Any way I can reach to you via FB
@@NightWorksMediaRYE Antipolo Vtec Mountains 🤣
yes yes SRD shop page is in the description always + im the same in charge with page maintenance so it will still be me on the page
Crv is always my dream car but due to “takaw sa gas kuno” had to stop buying one.
Been waiting for this video!❤️🤙🏻
And that’s why I chose to associate the head with a CRV mainly cuz of that locally we hear that yet that crv we did surprised us!
And tbh my ex decided to get a White crv mainly cuz of that and she does get 14.5-15km to a liter too! So I guess it’s consistent and she from Malabon so we know wherever she goes it’s “traffic” 😀
Good video Amigo! I enjoyed hearing about the exhaust system. It's a subject that I still have some doubts about. Especially how to choose one that doesn't make too much noise but is efficient.
Yes I’m glad you enjoyed it and I thought it was the “siento bente” :)
But it really varies on engine set up but a lot are depicted by displacement and rpm first…
But 2.5in full exhaust system is hard to be wrong with
Oh man just notice I didn't subscribed , just saw this video thank you brother love how you said, stop sounding like. Fool lol😆😂 alot of these you tube people think they know it all,,,love your honest opinion it's the truth, ,with age ,experience and we learn , much love brother 😎❤🙏
hahaha all good brother :) but thats true and we are just sharing ideas and stuff we learned from the forum days unlike now its just 5th to 6th had knowledge that we know has turned like the "pass the message" exercise in school
by the 7th person its a whole different story suddenly 🤣
Definitely if people did more homework before talking nonsense the car community would be thriving, ,was telling my son 4 piston is definitely watching your channel 🛠🛠👈❤🙏
@@shiftlifegarage3284 that’s true on sensibilities and all I agree there no doubt brother!
Hey Brotha! You’re in AZ and I’m going to be there in a few weeks for school! Would I put in the same intake manifold? Or would I need a vtec one, or port the intake manifold as well?
And same valves correct?? So I can buy everything ahead of time!
Both can work but vtec and non vtec valves are different
@@SRDmotorsports I have a p75 non vtec, I had the head resurfaced but I want a port for efficiency (and for boost lol) So I’ll buy the regular sized ones for the B20 P75, then I’ll make an order!
Yeah regular sized valves is good
Love the topic boss chief especially the exhaust part. 😂 And i can remember we did have a conversation about this too. 🔥
Thanks man and tbh for the past few vids ive been trying to make a decent visual on exhaust trail of the whole exhaust system and its only now i got to do it so it had to join in lol
which makes sense cuz aside from performance it does aid in efficiency and that goes for all brands too!
Im too hell-bent on understanding engines even MotoGp honda rc212v
if u get a chance to check out without flairings? its exhaust takes a "loop" under Marquez's seat
most prolly cuz of length hmmmm
The visual for the exhaust chief is easy to understand 👍agree chief. And nowadays na sobrang mahal ng gas, efficiency is a must have.
And i did notice too the fuel consumption of scav/downpipe/midpipe vs. full exhaust plus the smell of the gas fumes 😂
@@midnightkaiju yes easier to understand was my goal cuz its the same as siphoning fuel with a garden hose on a gas tank of a different car? but its hard to explain once u suck on the fuel? that "pull" is continous
like scavenging in exhaust terms
but then again fuel scavenger fits too lol when siphoning it 🤣
I'd love to do this to my old little 1997 CRV
Oh nice! You can spend some and do it on ur current head or spend smartly (didn’t say cheaper lol) by getting an “extra” p75 head so u can have the portwork done and be all ready and maybe next maintenance schedule bam! Drop the new head in lol
great explanation Ralph👍
Thaaaanks doc!
Actually I still would want to have a crv gen1 now 😎
@@SRDmotorsports
Go na with the CRV hahaha
Iconic B series engines 👍
@@blue3549 soon perhaps!! hihihi
What you said in 6:24, I think I saw that video 😁 So that they'll be "cool" like ERE and Signal Auto with the Toda Ds , hahaha
Hahahaha I knew someone will catch it!! 😎😎 yeah and ERE is incomparable I mean one of the Pioneers and why we are all where we are so kinda “foolish” to yearn to reach the status right?
I guess some do “dream” beyond 😂
Heck JUN auto mechanic of Japan we got a “mang Jun” ? 🙃

Great video by the way 🙏👍
Thaaaaanks brother :)
Watching here ralph!💪👊
me too actually! always fun to wonder about what a CRV could do! hey its already 4wd 🤣
is it possible to enlarge the port hole to the size of a gasket??
Yes but it would be nice to watch that Headgames video about portmatching also
@@SRDmotorsports thank youu friend
@@rezakurniawan2779 no problem :) any time
Any j series videos?
not much J series stuff yet at our end of the world
Love the vid!🙌🏾🙌🏾🙌🏾
thanks brother! this actually makes me not mind to own a crv one day 😏 then some crower cams loool!
Damn I want this done to my crv
I know someone here that easily gets 30mpg city driving seems efficient !
@@SRDmotorsports yea I would love to do this 💯
Nice yeah
What are you doing to tune these crv's?
Rechipped obd1 ecu + rewired ecu socket
@@SRDmotorsports
Thanks, the video was great btw
Thanks brother
Did you guys get the B20 P8R cylinder head with the VTEC sized intake valve faces?
Nah actually here locally I’ve yet to see one…which is sad
Do you have any home remedies for cleaning a vtec b16a head? Or should I take it to a machine shop.. I’m going to try to rebuild and port my b16a head
Oh thanks for checking this out and for this question! Quite a good question tbh
For home remedy I think it is safer to spray the head with wd40 let it soak overnight then next day on a basin of sorts? Soak the head in soapy water…a grease cutter detergent would be cool like sort of dishwashing style
Let it sit overnight and that should get it clean have a brush ready and power spray it with water :)
Most machine shops soak it in diesel spirits which is doable at home just proper disposal is a must ofcourse
Thank you 🙏 will give it a shot!
@@SamuelSoto17 stay safe man
Wd40 rocks 😀
I like the exhaust par the most. You explained it very nicely. You inserted also very informative pics here. Thanks bro.
p.s. Would like to know what happens if you change the stock exhaust with just the longer stock exhaust? On cars or/and bikes? For example doing it on Clio 1.2 petrol: stock VS just longer stock exhausts? Any particular good or bad effect? Thanks in advance. Just curious.
Yes I think a lot explain about exhaust but don’t have a visual aid so I tried to draw it to show
That’s a nice question actually I think longer stock could help the lower rpm from idle to 3,500rpm which might be good for everyday drive but I think performance above it will suffer and we might be caught up by a “King Rat” like on your video 😀
@@SRDmotorsports Aha, I get it. So, initially it would help, I mean in the lower revs. Thanks. What do you think of just removing the muffler on the motorcycle exhaust for example? Do you think that just the sound would be deeper or we might see also some changes in power, consumption... Thanks man.
@@RRRRefuelRideRace i think it might be noisier but
as long as the length remains the same its worth a try
@@SRDmotorsports I know about the noise, but I also thought of a little increase of power or even drop of power. :)
@@RRRRefuelRideRace if same length you keep you might gain some power actually
I’ve always been an old school V8 builder but I’ve been wanting to see how much I could pull out of a stock CRV b20 non Vtec with simple bolt ons and stuff and keep it very street friendly but have some vroom vroom. What all could you recommend? And would an aftermarket Cam be beneficial?
Oh man and “Eleanor” has always gotten my number :)
I think aside from this work on the head… it would be surprising for you to see a lot are still within the “realm” of what you do.
Example on the exhaust = same analogy if comp is somewhat mild then a mild exhaust would help indeed like a TypeR copy of sorts etc. same with induction but cam related
Mild cam = u can go big on intake
Hot cam = I can stay “small” on the intake to let airspeed stay good…
That’s a cam choice between
Crower 62403-2
And
Crower 62404-2
If a cam is the direction? My choice be 404 and just port the factory intake manifold :)
@@SRDmotorsports with port work such as this and utilizing the high compression pistons that are on the b20b? Is it? In a stock crv. Do you have experience with the stock ecu running this setup? Also what is a great stock injector replacement that has better atomization?
@@_jdgeorge_ not sure how good it will stay if stock ecu
Great vid as always!
I don't really get why people use "scav" "scub" "scuv" whatever the spelling is 😆 I run a full 2" exhaust with a 24" resonator with a straight through muffler. I like to keep things quiet.. comes with age? 😆
Madami siento bente.. but there is one particular gt-86 with a uel and a raspy ass exhaust that drives by our street that really takes the cake
I guess way back the short exh worked due to lack of parts and knowledge even I ran one but I guess running 14.8sec on a stock block D15b7 back then made me realize a full exhaust works and that was actually not even SS just crush bent BI
@@SRDmotorsports I guess you guys really nailed it with trial and error + experience.. Nothing beats that!
@@vince.r that is true and believe it or not my old d15b7 which was the first build i did back in the days totalled about 18-22 dyno sessions withh all the changes i did and tested
@@SRDmotorsports Oh wow that's a lot! 😮
@@vince.r def worth every penny
like the earlier vid i have on sri vs cai was on those days and that was my d15b7
Yes, I agree, locking the Vtec is actually removing the Vtec.
Yes sir!
👍
Thanks for checking it out man! December is still far but hope you are progressing well on your parts :)
@@SRDmotorsports thanks man I'm collecting all the info I can before the build. In December I will watch all ur videos again before starting
@@tana6850 awesome man! dont forget black friday sales and other seasonal sales
the discounts are always welcome
i know :)
@@SRDmotorsports thanks man
naka "TRD" (Tingog Ray Dako) is what we call it here but in bisaya language
Tunog Lang ang Malakas🤭
hahaha TRD wins!!!!
@@SRDmotorsports kidding aside sir, would porting still be applicable/ gainable in automatic transmission crv?
@@the063one actually that old crv I did mention in the video that got 15+ km to a liter? Was automatic at first but after the owner’s second busted a/T he decided to go manual
Prolly the engine torque was too good to turn his 16s rim too!
@@SRDmotorsports yes I remeber that vid with the properly gapped spark plugs
all the head porting ive ever seen is the same story everytime. "o every head is different and you need to know what to do." and everytime they dont explain their approach and everytime it looks exactly the fucking same as every port job on every head ever. You cant say shit like "o the way you port this head is not the same as you would a b16 head" and then not explain why and what the differences are
sorry about that as the video could take too long and boring for that but i see what you are saying
and pardon me if alot of times i assume the listener or watcher already understood the basics or the scenario
example Valve size to port volume, valve size to throat ratio and ofcourse "stroke" dictates piston acceleration which affects "signal" on how the engine sucks in air etc
the other aspects i mentioned or said is this:
D-series in relation to its stroke (90mm which is 1mm more than a b20) has quite high piston acceleration therefor sucking in more and with its small valves (knowing we can do cams and intake) these heads often time can and will lack "port volume" and that cannot be "seen" easily if u know what i mean?
now compare to a b16a head which is already borderline nearing "too big" of a port volume especially for a b16a with 77.4mm stroke
YOU cant port it for a B16 using tje D16 approach of lacking port volume? hope that makes sense...
this goes the same for the P75 its not on the "too big" zone yet... so the approach then cannot be "what youd do to a b16" knowing on that platform you could easily go overboeard... hope that makes sense
again thats all taking into account valve size
rod length, stroke and even cam to be used and compression... and with that? the video could take 2hours lol
so i hope that explains it a bit better and pardon me for saying "shit like that" cuz i expected those into it already covered some of the factors like sizes and all but def my bad on that
and yep id explain as you comment mainly cuz its worth explaining cuz i understood and im sure all the head porting youve seen if u ask theyd always make it sound too complicated like as if you dont understand lol
not here :) so i hope i got to reply to your comment properly man :)
@@SRDmotorsports ok yeah theres a little clarity there. What would your approach be on my engine? Its a b20 as well, the head is a p8r. For the p8r its a p75 head with 33mm intake valves and the combustion chamber is 47cc as opposed to 45cc and the diameter of the combustion chamber is 84mm matching the b20 block. I have yet to get cams for it but I was eyeing the crower 404. I have vtec sized valves in a b20. So should I port it more as if it was a gsr head or more as if it was a p75 head? From what ive read it flows similar to a gsr head
@@SRDmotorsports Btw I think that would be a good video to make. Maybe porting a head and explaining simply the theory you used for that specific head. Not necessarily how to approach every head but why you chose to port it the way you did for the application you are working on
@@timm5970 oh snap nice rare head there tbh here in this country I’ve yet to see one
But from the silicon molds I’ve seen it’s closer to a b16 shaped port but it doesn’t seem to be borderline “too much” port volume mainly because the valve stem size is still “bigger” than vtec so it’s a % lessened on throat cross sectional area
So you are on the money with the “gsr” approach but in a sense only on “amount” removed but the nonvtec p8r likes a little short turn help mainly since unlike the GSR has some port length “into” the seat letting it arrange itself (K series are taller in a sense here they’re tons better)
So widen the short turn a bit = kinda hinted on it on my earlier porting vid the “how to: TypeR “
Now publicly I’ve shared some of my approach lmfao but all good I mean a lot of the “experts” are less willing to adapt so if they do different? Well Pride is also different lmfao
@@timm5970 I was about to say thanks for your “shitty” comment lol kidding
But thanks cuz it gave me an idea and since I haven’t ported a P08 for a vid most of it we’re done with pictures? Next chance I get to port a P08 you bring up a good idea
Can share specific stuff for that specific head and why or atleast the analogy to why
Oh btw if idle was crucial yeah 404s are nice but I come from a vw lopey idle background so 405s I won’t mind hahaha
