I know that theres B,D,F series...does the series mean the class?Like A series is top of the line racing class?And does A and C series exist?Also what kind or cars does A and C go into if they do exhist?

 

Uhh, dude? You serious?

 

it's just a class of engines... like a species.
there's b, d, f, h, k, j, etc.
it's like saying frogs, dogs, cats, etc. then you have engine code that tells you exactly what engine it is.. like what kind of dogs(terrior, lab, husky, etc.), what kind of cat(lion, tiger, siamese, tabby, etc.) etc.
the engine classes have nothign to do with performance order(faster, slower).

 

Yea.A,B,C,D,F sounds like a grading system to me.Either for how much power they have or what cars their for.I'm just trying to figure out how it works.

 

its just the way it is......

Ah.Ok.I just thought it might be like in games how they have A,B,C,D,F class cars and A is the high performance cars.

 

There was an A coded engine. A20 i believe from the 89 Prelude. Piece of **** motor. I think the Legend has a C coded engine. Just because of the name of the engine doesnt mean they are better then others. Your basically asking "why do they call a car a car" Because they [freak]ing feel like it thats why

I think my question is a bit more complex than asking why a car is called a car.

 

it's just whatever the engineers designate it to be. the engine code usually tells you the most important things about the motor. here's an example:

B18C5

B = engine class(b series)
18 = displacement(1.8 liters)
C5 = specific engine code(tells you this comes from an Integra Type R)

essentially it's just a classification system to make things easier. saying that i have a 1.6 liter honda civic doesn't tell me much. since there were more or less about 6 motors that have 1.6 liters of displacement, some have vtec some don't; some are dohc(dual overhead cam), some are sohc(single overhead cam); one has roller rockers, the others don't, etc.

Here are ALL of the Honda engines, so there is more info here than you're asking for.
http://en.wikipedia.org/wiki/Honda_Engines

Remember that any non-JDM (Japanses Domestic Market) engine will have a number after the engine code.

For EXAMPLE... B18C5 is the USDM (U.S. version) 98-01 Integra Type-R engine. If it had a 6 on the end instead of a 5 it would be from the UK. If it was just a B18C it would be JDM, but since there aren't any final numbers in the engine code on JDM engines you have to be able to differentiate GSR engines from the Type-R engine (on DC2 Integras), the main visual differences are the intake manifold, exhaust manifold and a Type-R should have a red valve cover.

Don't worry, it just takes time and research. Use the search button alot, please.

As far as the engine series (ABCDFHJK...) They're just letters Honda picked for certain engines, and all random to my knowledge. But like MiMiK said, the numbers are what tell you the displacement of the engine, like a F20C is a 2.0 Liter, H22A is a 2.2 Liter, K24A is a 2.4L, etc.

My engine's a D16Z6, so it's a 1.6L D-series, and you can tell that it's from a USDM 92-95 Civic/Del Sol EX/Si from the "Z6", and this is a VTEC engine. But the D16Y8 is also VTEC, where the D16Y7 is not. So each engine series has it's own set of rules that you'll eventaully learn. Like I can tell you now that all K-series engine are i-VTEC, and that the F20C and F22C is completely different from the other F-series engines. But from what cars the engines originate from is what you'll simply have to learn on your own. As long as you have the passion for this stuff it'll come to you easy.

And JDM is the best Honda engine right?And type R is better than GSR?

 

Most JDM engines have slightly higher compression ratios, slightly larger camshaft lobes, and different gear ratios in the transmission than the USDM versions. Some JDM ECUs are tuned differently, and some have speed governors, and some do not.

Yes the Type-R is a handbuilt, hand ported engine built for higher RPM power (20 more to be exact than the JDM GSR) mated with a closer ratio gearbox with a higher final drive and LSD is standard. So it's better in NA terms out of the box.

You could say that a USDM GSR would be better for a FI application, like a turbo, than a JDM Type-R because of the much lower CR and people find the longer gears better for getting traction and staying under boost for longer.

NA= Naturally Aspirated
FI= Forced Induction (supercharged, turbo, nitrous)
CR= Compression Ratio
LSD= Limited Slip Differential

 

Whats LSD?

In Lamens terms, the Limited Slip Differential makes both wheels spin at the same time, all the time, and at the same rate of speed. (someone correct me??) It's called a LIMITED Slip because there is a limited distance the differential (a gear in the transmission which makes the wheels spin via the axles) will allow the wheels to spin freely before locking together, which to my knowledge is a very, very short distance.

It's not a grading system. It's just different engine groups.

You can find a lot of this information on Wikipedia even.

The series of an engine puts the engine in a certain class. For example, C and J series engines are V6 engines; C being the 90 degree versions and the J series engine 60 degree versions.

A, B, D, F, H, K, L, R and ZC engines are all inline four cylinders.

G-Series engines (from the Vigor and a few other models) was an inline five cylinder.

N-Series engines are the new diesel inline fours.

Engine codes usually are in this order: X00X0 (letter, number, number, letter, number). Not all engines have that last digit; these are usually JDM engines. Most JDM engines do not have the last digit, but a handful do.

JDM is FAR from being the best all the time. Having a JDM engine here in the US means certain parts can be difficult to find, such as gaskets (some can be matched to a gasket that could be trimmed, but not all).

Most overseas engines don't live up to the hype that is put on them since most people only take into consideration the higher horsepower trim levels such as the Type R and SiR, but never think of the 1.4i (for example).

There are some good engines overseas, but I'd venture to say the US gets the best selection when you take all the trims into consideration.
