Tbh i think if someone is going all out they don't need a vtec head, those non vtec put in crazy work, people keep sleeping on them. Ive been doing some deep research on the non vtec h23 and man those things got mad potential and no one talks about them lol love the porting work and showing this b20 head some love
@@SRDmotorsports exactly! Those motors are bulletproof from factory and make big torque! Only thing that holds them back are the flow of the heads and the cam
Good stuff man! I finally built the courage to port n polish a spare B18B head I also have and gonna see how much power we can squeeze out of a stock b20 . Really using your videos as tutorials and guidance ! Thank you !
Thanks brother! Actually yeah I’ve been thinking about that and leaning towards it just cuz it is different and probably has less of it here Plus I always loved La Sata Racing back when it was nonvtec 💪
@@SRDmotorsports I'm currently busy with a setup of my own, B20b8 with a mild regrind cam...Other than that still stock. Running 14.5sec 1\4mile. Going to be trying some of your methods to become faster😁 I'm watching from South Africa btw
Ohhh Bafana Bafana!! 💪 good times if it’s nearly stock b20 Do check the 4.4 vs 4.7 video I did Not to check gears but to understand the rpm and powerband U may improve ur 1/4 time if u get to fully use the powerband u have with the gear ratio u have
@@SRDmotorsports Yes Bafana Bafana!!😂 Thanks! 💪 I've never seen that video, I better check it out. I used to run a S80 long ratio box, then I built me a what we call over here "S4C vtec" box, which is basically the short ratio box. That gearbox made a huge difference. Thanks for the advice.
^nice videos as always!! i noticed when you are showing the exhaust ports starting aroung 11:30 that the right side (when head is upside down) was ported higher than the other side... is it the case or is it just some camera stuff playing tricks?
Good eye… I think what it plays tricks on our eyes is when I show exh port # 2 it’s direction is biased to the left (But when inverted on my video it’s to the right side) and I rarely say it but the exhaust ports are directional meaning the #1 and #2 are biased to the “left” and the #3 and #4 to the right (but when inverted it’s the other way around) Maybe just maybe that’s what most make a mistake on trying to port it on how it “should” be than how it’s supposed to be
Yes yes the port floor is affected as it turns left (Right side up) the valves are still at the same spot and the short turn length is the same length so the right side kinda like bends higher when upside down
@@SRDmotorsports oh ok i see what you mean now! Thank you for the explanations, also thank you for this kind of content, we don't see much of that on youtube, and not that detailed too! Keep it up, maybe i'll consider sendibg you my b16a1 head when i will start gathering parts for my b20v 😉
Oh man thank you for the kind words too! The content is really based on how the “forums” were back in early 2000s It was just all good tech talk and we make fun of FnF … now forums is gone and it’s Furios X I guess “family” for Dom lasts longer hahaha
Hey man i love your videos . Very informative.. Im building a b20v GSR Head p72-2 B20b block stock I have been trying to find type R Cams But have had no luck , what are some good copies , or alternative cams that compensate with that block?
Cool project!!! I think first your worry is to clay test (locked vtec) because the b20 intake valve pockets on the stock b20 piston isn’t the same spot as vtec so to avoid danger u can avoid the close clearances u will know when u clay test
I think with the TypeR prices going up… a most over looked cam is the crower 402A not crower 402 but with the letter A designation as the A in 402A means TypeR style primary and secondary so only the vtec lobe is 402 and the primary and secondary is like a TypeR it might work a lot better this time actually for a set up like yours You can PayPal me your thank you Hahaha kidding Amigo! Good luck and have fun man thank you for checking this out
How much power do you gain from doing this? I have a B20z2 w B16 trans. I want to Vtec swap it eventually. I’m put the Ls intake manifold for now. I have clutch headers exhaust I’m map it when I switch the intake manifold.
I did a few f22 non vtec accord heads… actually I acquired a few whole engine as I planned to turn it into a project Then suddenly somebody seeked help their accord blew up so I sold and installed it to their family car so I lost it :(
@@SRDmotorsports my only real question with that is if the process is the same. I want to do work on my own and have good knowledge on the shapes, sections and areas of a head. The the intake manifold tapering and everything in the video the same for those sohc non vtec engines?
Same process and all… just each engine is different like a b16a is borderline with its head being almost too much port volume that’s why b20vtec works so good but a p75 crv head can benefit from a bit more port volume Etc and the rest gotta match as far as what kind of header, compression and cam
@@SRDmotorsports wow man i’m glad to hear that. For the past couple years i’ve been researching what I can do with hondas and have really gotten into it deep with vast knowledge. But now that i’ve aquired it and obtained all necessary parts for the rebuild and became more experienced in the driving aspect of feeling an engine, I know exactly what is necessary and what I need. But this machining pricess is completely separate and so cool. It’s not only gonna make your car faster, but learning about in depth head work and understanding PORT VOLUME is amazing because what I think you just taught me is that “too much port volume” means that the block will not be providing enough torque not only low end but throughout the powerband, even with a turbo! Volume is a good thing but the head will need much more air flow and fuel allowance and compression. Therefore, the b16 is better on a block with not only more displacemnet, but as well as beefier, in this case comparing the b20 & 16 blocks. It may seem like i’m eager to obtain a license in dick riding, but this aspect in performance is hard to come by and it’s very technical but i get to learn and understand why these things works and it’s very wonderful. I’m a nerd when it comes to learning, so thank you for teaching me something!

Oh man that sounds like a fun “stock” b20!!!
I am not gunna lie i would rather pay shipping to you an pay the best to do it. Worth working a little harder to afford it
and it’s guys like you that help make the sport worth more than a lot man!
Nice job great work great explaining tutorial is on point
Thanks bro!
Very nice video.
Thanks brother I’m glad it wasn’t as boring hehehe
@@SRDmotorsports not at all. In fact, if you want to get more technical I am all for it.😁
Sweet man! Let’s go! 😎
Awesome stuff, I'm learning so much from your videos... Keep it up bro✌
Please do the B20 non vtec build

@@malikabrahams1597 yes if u have the s4c one that’s good now u can “adjust” ur driving to take advantage of it :)

quite a few, but can’t be compared with b16 heads that has higher potential
@ it’s jus for now until I Vtec swap it. I would like a type R head. Let’s see
Yup
Have you ever worked on F22 sohc non vtec engines?

No worries man and yes u kinda got the grip of what I meant and atleast this way ur starting off correctly and continue to improve more
thank you
You’re welcome man
So if i have a non V b20 head how much should i tell the dude to shave off im just doing a mild Street build? Its for a auto crv😂
the machineshop will know if it’s just a simple reface to ensure flatness and new surface for rebuild on new HG usually it’s 0.005-0.010” only
