How to Build the Honda/Acura B-Series Engine!

[@JacobMueller]

This year Im rebuilding a 1 owner, 320k mile CRX from Alabama, which is in pretty great shape overall. Next year is building a B series for it...what perfect timing for me that you guys made this vid. Really going to enjoy the next 45m.

[@Lost10mm.]

That's awesome, got a few honda projects going to. Hope it goes great for you.

[@foshoitzdanny]

Hopefully you got some $$$$

[@rolls5328]

Never seen a street NA engine thought out so thoroughly. World class! Would love to see it bolted together in a future episode if it's not asking too much. Magic content as always.

[@motoiq]

its coming

[@customconnections2425]

⁠@@motoiqThanks for that! Can’t wait.

[@uses0ap]

B-Series are incredibly efficient. Would like to hear Mikes thoughts on LS/B20 Vtec

[@motoiq]

I like those

[@johnrobie9694]

I'm not a Honda guy, but found this video very informative and gives me some things to consider for my engine rebuild.

[@Ravenousjoe]

I'm the same way, I know they are good, just not my thing. After this video though, it's nice to see a solid series of small engines that would make for a great engine in a super lightweight build.

[@Boostd4]

Great video, glad to see the B Series still getting the attention it deserves.

[@micksmith7414]

Great basis and ideas for planning out my build. 90 crx si and im basically going with a " tech update" approach. Using current tech to update a B18 c. Itb, coil on plug, all the newer Metallurgy

[@CitiZen1.0.1]

Love that i found this video. I just bought a 92 eg si with a b18c5. Unfortunately it already has aftermarket pistons and rods but the rings are likely worn and its burning oil. Hoping the rebuild comes out to be enjoyable. This motor will be so much fun for that customer.

[@em1tuning797]

Very much appreciated when producing B series content.

[@Bruce-r4z]

i grew up on the D and B series and have special affiniy for them. K series is awesome and benefits from all the initial growth R&D from B series IMO. Have B17 out of GSR in my 87 CRX si and a D seires with Jackson Racing on D16 in 88 EF. I own newer VW/Audi but love those cars to my death.

[@TheEvilTwinCG2]

Great video. Info everyone needed 20 years ago. But never too late because b-series is still the best for me.

[@TheScotchula]

Pretty sure Mike has forgotten more about cars than any of us will ever learn.

[@scottg1962]

Awesome video and great information as always. I also run Kelford cams, the 176-C in my b20v. Great flat torque without compromising top end

[@IIStyx123]

Love this!!! Now it makes me want to dig into the internals of my GSR!

[@yeahman1756]

Ah! the Beast Series... I fawkin grew to lov'em because I hoarder a bunch of B series headd and blocks(b18/20 short blocks, b18c1 long blocks, b16 heads and a few ITR and CTR heads) , B series transmissions and B Series accessory parts when I run across them at junkyards or social media online for cheap. I'm NOOBIE idiot to the automotive engine building world because I'm on the business industry side all my life , but do understand the concept pretty quick as I do research and read auto mechanic books about them on my free time. I now just need a good size garage workshop with a couple of machines to work on them like restoring and overhauling them to oem specs with new advance technologies and building some of them as race engines as turbo applications as a hobby. it feels therapeutic peace doing so at your own pace. unlike the business world where you constantly on the go with pressure and stress everyday.

[@groundcontrol6876]

43:37 He’s one rich dude too. I’d like to see the receipt on that thing, you could probably buy a pretty nice car with just the cost of the engine and build. 💰 I’d love to have that thing in my CRX! (with A/C of course). Would be a dream come true. Like seriously, I’d be ecstatic for SO long, and every time I popped that hood to just look at it and every time I drove it, felt it and listened to it would just be friggin’ magical. I’m gonna have to start setting some money aside to see if I can have that done by you guys. The cost would be even higher though since I’m not in the US, and the install would need to be done by another shop which is a bummer so I’d have to find one that I can really trust and be happy with. I mean, install is the easiest part of the process I suppose so I shouldn’t be too worried about that, but still, would be so much better if I could just drive my car and drop it off at your shop, then cry tears of joy when it comes time to pick it up.

Vapor Honing is just a fancy name for wet blasting. Supposedly wet glass beading seals microscopic openings in aluminum, preventing corrosion and oxidation for years to come. That's certainly a huge advantage for what should be very little money.

It is relatively inexpensive.

Could you talk about the problems you have to account for when using oversized valves with bigger camshafts? Like How do measure v2v, dial in the cam timing, specific valve job to gain clearances

For Hondas. B series are the best sounding engines. Power? They are outdated. I’d still go with. B series over a k still.

[@Elver_Galarga_jugo]

Im torn between going the NA route aince i already have some 12:1 pistins for my GS-R and aim for about 180-200whp or go with a turbo and ahoot for a conservative 250whp. NA route might be more expensive for less power, but i just love NA engines.

[@BTDrgonzo]

Do you guys ever build 2zz’s? If so, do they respond to the fluid damper?

[@kinqdavid3149]

So I’m stationed in Germany with a imported b18c1 in a 97 del sol will all this fit my engine because this kinda what I’m looking for im mechanically inclined but I’ve never built a B series before a few guys here mention some of the things you talking about I’m staying na but I wanna have the unlocked slot for more already there 400whp for now with potential for a simple upgrade to 800whp if I needed it

[@klemenzfreyr2106]

I have a b20a5 engine and I wish it had more aftermarket support for it. I still love it tho. I'm thinking of getting a another engine to rebuild for boost since it's a closed deck. I wish it was more like the other 90's bseries

[@h3xd3m0n9]

Everything b fits

[@TheVesterRaev]

I have a request! Can you please have a look at what k-tech did to the f20c motor? I’m intrigued in that strategy of having such lightweight pistons for a NA f20c, and if it’s something you would be able to buy and assemble outside of Japan.

[@motoiq]

Watch our K series stuff, it's almost the same.

[@Truufreshjay]

I have the bastard B series, the b21a1 and i’ve always wondered what made it so different than the other

[@Constan19]

It would be nice to see the final result on a dyno

This is a customer engine so when it's gone, it is gone.

[@Snake_47]

How would one go about a 10k + RPM B18c7 (aussie spec) ? Looking at rebuilding mine once I take the motor out. Power figure is similar to the one featured in video but a large aspect is being able to hit that 10k + goal.

[@motoiq]

Spend a lot of money. Not have it streetable.

[@Snake_47]

@@motoiq Ah bugger, the plan is to spend the money and be streetable, maybe ill reassess my goals

[@motoiq]

High RPM means narrow powerband and less torque.

[@TheEthanjk10]

Great video, not hating but I didn't learn to build a b series engine in this video lol

[@jinezawa7089]

So I wanted to ask, are the B20 sleeves as weak as people say? It seems to be a big point of debate. Would they be good for an NA b20v street build? Not looking to build a 10k rpm race engine, just kinda window shopping to figure out possible future routes to take with my teg

[@motoiq]

Yes they are fine.

[@LiveWire-it8zr]

About what boost pressure would you advise going to studs. Like over 30psi? What about arp bolts instead of studs?

[@motoiq]

past the mid 20's

[@rollthelosingdice]

Hey I got a question, do you measure valve stem height from edge of the valve seat shim to the end of the valve on Honda engines. I can't find the answer anywhere.

[@motoiq]

With a snap gauge.

[@rollthelosingdice]

@@motoiq I'm using calipers, I just need to know if you measure from the head or the spring seat. My numbers are too large measuring from the head.

[@CJ5EVOLUTION]

A few questions, do you use the same Cyl head gasket you are planning for the build when you torque plate or without? What is the final compression ratio with those pistons for that build?

[@motoiq]

the same type of gasket, yes. 11:1

[@CJ5EVOLUTION]

​@@motoiqthanks for the reply, is this engine knock limited that it can't be increased to 12:1 on pump gas? Or using octane booster.

I don't recommend it

No

[@brentthomas712]

Forgive me guys for the noob question but when reassembling, does the thrust side of the piston go in a specific direction in the block?

In the direction of rotation

How easy is it to source engine parts for the B18C6 Type R nowadays? I'd like to refresh mine. Is the 2618 piston as quiet as the original P73 honda pistons? I had a set of wiseco pistons in a B series turbo build I did back in the day with 2.5thou clearance and they were ever so slightly tappy at idle. Got on my nerves a bit.

[@motoiq]

You can't get the original Honda piston anymore.
