Wow I’m grateful for the amount of detail you give in your videos. Finally got the motivation to finish the the project I never started. B20v GSR head NA to see if I can keep up on the track with my best friends GR Corolla

[@SRDmotorsports]

Oh that’s definitely nice to know man! And now u can find more “fun” in your project and so go for it! Sounds like a lil beast in the making!

[@frivera735]

I was smoking gr corollas at the track JDM gsr matching trans bolt skunk 1 tuner cam made 178 on a hub dyno gutted car removed front and rear crash bar almost full spherical suspension del sol seat 6 piston bbk gsr rear disc car is a lot of fun didn’t try a bucket seat car was still fast

[@shiftlifegarage3284]

Dam I need a kit to build my b20v times is hard but I am going make it work glad my son showed me your channel I can watch this all day

[@SRDmotorsports]

oh maaaan thanks for that! i hear ya on times being hard... work been slow here too.. well since its a b20 it prolly could do pistons and some crower nonvtec cams (cheaper) stick with nonV head for now if they say "why no vtec?" just say "i got 4 wheel drive bruh" 🤣

[@shiftlifegarage3284]

Awesome it's crazy I was thinking to stay non vtec I kinda love the raw nonV and I think it would be awesome

[@shiftlifegarage3284]

Definitely more reliable as well is what my ultimate goal is

[@SRDmotorsports]

@@shiftlifegarage3284 tbh it’s always at the back of my head… I mean sure it won’t make as much as a vtec version but crower has a decent sized 405 grind I won’t mind the lumpy idle too lol

This is crazy my dad is building a similar kind of build and he always said 2.0 bottom end and the 1.8 gsr head is the perfect motor build and he is 44

[@SRDmotorsports]

oh wow awesome and indeed crazy! just like in the K24 RBB video i mentioned the gsr head is a few cc smaller in port volume than a b16 but that also means excellent torque and u can run "more cam" especially with a 2.0 bottom end cool! even if your dad is years ahead of me see that even old timers "know" whatsup! 😏

How much would it cost me to build a b20vtec? Planning to change my ph16a engine Thanks, love your videos

[@SRDmotorsports]

really depends but since it’s a “vti” it might be more costly due to axles , transmission, linkage costs etc You can hit us up at the new page for more discussions, as the old page i no longer have access to due to my old fb getting hacked

[@ErrickWillich]

Now did he have a crank girdle to make it safer to rev it that high

[@SRDmotorsports]

This one didn’t like most b20 but I agree a girdle makes everything more solid

[@prasquete]

Hello That compression calculator can be use for other motor...

[@SRDmotorsports]

yes if u include all the proper measurement like adjust deck height to suit and match as well as combustion chamber volume and piston dome volume crank stroke and rod length together with piston compression height etc

I will be daily driving my del sol b20vtec b16 lsd trans. What kind of power can i make on a fairly simple build and be reliable?

How do you cut open the manifold for porting? Are you using the dremel for cutting with what kind of cutting blade? How do you put them back together? Tig weld?

[@SRDmotorsports]

oh hey sorry for the late reply... nice comment now it gives me an idea that maybe one of the future vids we show cutting it 🤣 believe it or not 90% of the cut is using a hand saw with a steel blade for cutting steel (hss) aka "lagaring bakal" my angle grinder as a thick disk the usual ones? so it cute tooo wide so wat i do is i use the angle grinder as "starter" to get the edge started then switch to hand saw... believe it or not since its aluminum? it cuz not as hard as if it was steel... though not as easy as wood 🤣 yes Tig weld it shut after... 90% of the time we clean off the welds and prep the details of the outside so its "mukhang stock" lol

What's your thoughts on putting an oversized valve on a Honda heads like putting a 1 mm oversized on an intake side in a H22

[@SRDmotorsports]

on D B and H it depends I mean if the set up needs it… like for example if the set up is on Pro3 cams and it’s still “needing” a bit more? As can be seen on the dyno then yep it will help… But let’s say anything mild the stock valve size is good for big numbers as it is

[@angeluribe2232]

@@SRDmotorsports it's because the bottom end is pretty good high-compression 240 psi all across not sure what compression ratio the head and block are almost mailed to the max and Pistons are npr racing 11:1 and I want to make more power the head needs more work everything is stock except the dual Springs and titanium retainers from Super Tech

[@angeluribe2232]

@@SRDmotorsports it's because I seen on the Supertech website they had 1+ valves for my motor and I was thinking about it with a cam Skunk2 tuner2

[@SRDmotorsports]

That would be okay to try but if a Bseries stock sized valve 33mm is good for 308-310cfm then the H22 with bigger valves should top higher than that… and so with that we know unless it’s topping up at 310whp then stock valve size is still okay, safer on P2v and v2v too

[@angeluribe2232]

@@SRDmotorsports I was just wondering what were your thoughts on this thank you for your recommendations , it because a dragster that I met at the drag strip he had an H22 and he told me just to put 1+ valves intake side and get a good head port and to leave the stock cam he said I would make good power but I want to put a bigger cam too cuz i want all the power🤣😂

how many seconds for quartermile on this build

[@SRDmotorsports]

Last we did this diff owner/car it was 12.1sec

[@findtherightbeat]

Are you running seat angles on the intake side quite close to 36°-45°-67°-80° and then blended into the throat? I'd understand if you don't provide the details, just thought I'd ask

[@SRDmotorsports]

that is close yes 35-45-68 mainly the trick is the curve/blend after the 68

[@gigiofficial5309]

What compression ratio piston jasper running?

[@SRDmotorsports]

12.4:1 1Up pistons

[@christopherkennedy727]

Can I get these numbers with a b16 head made in 94 or better described PR3-2

[@SRDmotorsports]

Yeah i think its fine i mean even here a b16 head is more common perhaps add 0.010" head mill to exceed the gsr comp it gives with their chamber size

[@jdm-r2524]

Question??? I have a 96 spec type-R motor "JDM-R". Should I just do head work and manifold work. Leave bottom stock. Running all motor. With 9k RPM... or leave it all stock. Oh chipped ECU.

[@SRDmotorsports]

I think manifold work and head work is a good start and step forward A compression test could also give better ideas if it’s healthy and what state

[@jdm-r2524]

Yes compression test for sure. Thanks...we'll plan to do head and manifold work.

Sadlyf imagine cost of that (aftermarket pistons and eagle rods)

[@ErrickWillich]

You say pump gas what octane. 93 is the highest I have at the pump and I'm building a b20v after doing some calculating is gonna be 13.7.1 compression

[@SRDmotorsports]

97euro octane so 94US equivalent But it’s really on tuning I’ve seen people blow up even on 99 octane and just 12.5:1 comp

[@ek4dr98]

? My builder tells me to ditch my b20vtec and build ls VTEC why is b18 block better

[@SRDmotorsports]

That’s a common misconception, as way back it was claimed cuz the b20 has siamed sleeves meaning the steel part is merged together they say it causes cracks but I’m also a tuner since 2008 and I know cracked sleeve is 98% on the tune and 2% fuel to be blamed Not saying your builder is wrong but we got a b20vtec running 12.5s on pump gas not e85 no trailer a pure street car and it’s been running since 2017 :)

[@darylcunanan8972]

May I know how much is the whole budget for this kind of engine build?

With current prices now? It might reach an easy 250-270k But this would whoop Ecu Later’s B20vtec that we built, that already runs 12.5sec on pump gas

I am loving these b20vtec build videos. I am going to be building a b20vtec soon. One question, when you say this engine will be on pump gas, what do you mean by “petrol blaze”?

He's in Asia and he's referring to Petron Blaze: Type / Quality Level Premium Plus Grade (RON 100) EN 228:2005 PNS Euro 4-PH Have this guy build your head, he's done the WTA head on Elusive's DC2

[@SRDmotorsports]

thanks @findtherightbeat yeah sorry didnt have a logo to insert on the video its 99-100ron so most likely a US 95-96octane rated and suuuuuper glad @TrackSol this entices you and the topic discussed on cams and intake ? same on b16 or b18 the bigger cam weakens the signal towards the end of the duration so either even more comp or better intake or hmm ITB? 😏

[@SRDmotorsports]

@TrackSol lemme know if u dont mind... your planned b20 and pistons so maybe on the next video i can insert a section of the vid computing it for you the compression i mean il record the vid while we compute as we all know... there might be 5 or 10 more in the world planning the same :)

[@TrackSol]

@@SRDmotorsports Sure thing. Since this will be street car using American 93 fuel (98 RON), the build is B20 with B16A head, YCP brand ITR spec 84mm piston with P2P0 rods, ARP2000 rod bolts, Skunk2 valves, springs and retainers, Skunk2 ITR style manifold and Skunk2 70mm throttle body, Skunk2 Alpha V1 header (long 4-2-1 with 1+2 and 3+4 pairing).

Oh yes yes only different on boost is pistons choices But it definitely applies and it’s prolly what some don’t share and what most don’t know? Why we see two engines make 350whp But one engine does it at 30psi The other only at 21psi cuz of efficiency Il vote the lower boost cuz less stress

Back then (parts were acquired before this pandemic… around 2019-2020) Was around $1,500-2,000 Granted that was including the actual head this is being built from the ground up But some b16 owners or gsr owners may have it cheaper a bit since they got a cylinder head already

How much hp did you get on this build?

[@SRDmotorsports]

Hello…this hasn’t been fully assembled/finished as the owner has a newborn now so we know how that goes 😂 but this is an easy 240-245whp pump gas as in 2018 we did a similar but with non forged pistons (1Up) and we got 235whp on full exhaust with a chambered muffler.

​@@SRDmotorsports Interesting thing that's often overlooked when it comes to endurance engines. Same thing with the JDM D15B Vtec vs the D16 for road racing. Some say it's negligible but people have to listen when an experienced machinist speaks to them about cylinders out of round.
