What are all the honda engines named. All the ones I heard of are the b16 the h22 and the b18 but I heard of something like b16a or b16c5 What does that mean

knightm3 · 08-13-2002, 04:40 AM

Out of the B series engines, B16 and B18 were used in the Integra/Civic, while the B20 and B21 were used in the Prelude. H series motors, the H22, H23, etc. are used in later gen. Preludes as well as some Accords I believe. In regard to the "b16c5", that is really the B18C5, the motor used in the Integra Type R. The first number in the motor ID is the displacement figure [eg: B16=1.6L; B18=1.8L and so on]

Anyone else feel free to add if I've missed something important- thanks.

Honda motors Suck

jp

get a d16z1 put in your prelude now thats a motor SOHC vtec

now why would u want a sohc when u can have a dohc ? is single better?

stryka · 08-13-2002, 05:15 AM

Which motor has a DOHC that produces 220 hp staok. I saw one in mtv's true life im a street racer

C30 and C32 are the engines used in the TL, CL, Accord V6 and NSX. Obviously the NSX shares only the most basic design components with the other variants.

F20C is the engine that goes in the S2000, but the F22 is a powerless crapper that went in the 4cyl accord and 4g Prelude S. The new RSX and Civic Si engines are the first of the K20 line...

There's really too many to list.

As for 220hp stock motors, no Honda engine like that exists. There are two 220ps (216-217hp) engines, the K20 in the RSX Type R in Japan and the H22 in the Prelude Type S, again, in Japan.

Just to add/clarify, the B20A5 and B21A1 were used in USDM 3g Preludes. The B20Bx and B20Zx were used in the CR-V- these are the motors you may hear people talk about a "B20 VTEC" or "CR-VTEC." It's a B20B or B20Z with a B18 VTEC head on it.

Learn something everyday... thanks for the clarification

No problem. I just noticed- WHY would you have swapped a B20A5 into your car?!

knightm3 · 08-13-2002, 06:59 AM

you're not familiar with the B21 "oil furnace"? haha

marcucci · 08-13-2002, 07:05 AM

The b21 is only marginally worse than the B20A5 in terms of r/s ratio, side loading, and ring/wall wear. They are both probably the worst engines Honda has produced with regard to reliability (no offense). They happen to be the torquiest, too, for the displacement, though.

I've often wondered why more people with 3rd gens don't do B18, "CR-VTEC", or even B16 swaps. I'm also dying to see a K20 swap- it would be a pain, but I think it would be VERY worth the results (200HP 6 speed!).

knightm3 · 08-13-2002, 07:12 AM

I agree the B2x series are the worst motors to come from Honda. No offense taken. But the fact remains, I burn a ton less oil with the B20, and the increase in reliability [it just "drives" better] is worth the slightly lower performance numbers. I haven't checked on the availability of B18's or B16's in my area. It took 6 weeks and 4 tries to find a B20 that wasn't defective

Now that you bring it up, I'm seriously looking into what it takes to swap a B18 in.

marcucci · 08-13-2002, 07:47 AM

Keep in mind that the B18 isn't much better- that change in displacement does go right to improved bottom end geometry, though. The B16 can be made to spin to 10,000 RPM reliably, but it would probably take that much to make significant HP (say 200) w/o boost. It all depends on what you want to do, I guess.

alvin · 08-13-2002, 11:06 AM

hmm I guess I'll take it a little further....

b16a = Si/SiR motor 160hp USDM, 170 HP JDM, DOHC VTEC
b16b = Civic Type R motor, 185 HP JDM, DOHC VTEC
b18b = Integra LS/RS Motor, 135 HP, DOHC
b18c1 = Inregra GSR Motor, 170 HP USDM, 185 HP JDM, DOHC VTEC
b18c5 = Integra Type R Motor, 195 HP USDM & JDM, DOHC VTEC
f22 = Prelude/Accord Motor, 130 HP USDM, SOHC
h23a = Prelude Si/SR Motor, 160 HP, USDM, DOHC
h22a = Prelude VTEC Motor, 195-220 HP Varying from year and JDM or USDM, DOHC VTEC

Anyone make any corrections to any of these if I am mistaken... I am not 100% sure on all of them but I am pretty sure I am in the right area with the numbers... there are MANY honda engines but these are some of the most common ones.....

HoNdAHaXoR · 08-13-2002, 11:17 AM

yeah you left out a couple hehe
f18
f20b
f22 TWIN CAM=(think of a 2.2 h23.. basically a h22 with no vtec)
and a slew of civic motors hahaha

marcucci · 08-13-2002, 11:22 AM

F22A= USDM 130HP SOHC 2.2L
F22B= JDM ??HP DOHC (also VTEC)

My guess is that the B1 was DOHC and Bx was DOHC VTEC.

grlielude · 08-13-2002, 02:11 PM

so whats a f18 and a f20b?

nxfx86 · 08-13-2002, 06:02 PM

if i was to swap a b18c5 engine into a crx will there be enough room to turbo charge it?

Personally, if I spent the money to have a B18C5, then I would leave it NA... all the internals are built to handle high rpm NA power (large overlap on cams, etc... that are bad for FI). If you want to turbo a B18 then save some money and buy a GSR engine, then you can put the money you save by not buying the Type-R engine towards the turbo.

This chart seems pretty accurate to me:
