D series vs b18cr compared

[Bludger]

Apart from the very obvious, is there much difference between the two motors in regards to stripping them and putting them together?

[teaseR]

is it necessary mate.
i thought u are more HONDA educated than the spams u make!

[Bludger]

its a serious question, and i haven't torn down Honda engines, thats why i'm asking:)

EDIT: i was asking more so about the block, not really concerned about the head...

wtf dude. are you serious?

d series is a sohc (single cam) [most anyways, except for the si zc)
b series vtec is a dohc (twin cam)

tell me if theres a differences. cant believe you even ask such a question after q ball closed your 1st thread.

thx captain obvious.
lol

You guys are fcukheads, you should read what he is actually asking..... In regards to assembly the heads would be quite different since B series has the whole VTEC system and plus the DOHC setup. However, the bottom ends would be pretty much the same AFAIK with only a few minor differences.

i was asking about the bottom ends of both examples

thanks for the captain obvious posts, i deal it out, i take it too :).

but yeah, stripping bottom ends, much of a difference?

and putting it together?

My 1st thread was created in response to all the how much and what should i do threads

yes, that is obvious, what you're pointing out, but thats not what my question was aimed at:)

learning how to strip down a motor and put it together again.
i've done heads b4, so i'm not concerned about that side of thinfs.
more concerned about the bottom ends, are they similar?
if i strip the D, would it be the same as stripping the B18cr?

[bennjamin]

D series and B series - almost exactly the same bottom end.

Only difference is the head with the UPPER parts of the head with DOHC VTEC.

ahahah I should be called Captain Rock Obvious :D
i know not to browse forums when I have just woken up!

bottom end of b series is far more superior than d series the crankshaft,oil pump,water pump, pistons, conrods etc .... all have been upgraded to be reliable and to be able handle revs up to 9000rpm

not relevant to this thread.
His question is about taking apart / reassembling. Both B and D series bottom ends are quite similar and no hassle between the two

[beeza]

True dat but made me realise the fundamental difference between both bottom ends.All good!

difference in the bottom ends depends on which d series bottom end you have. the d15b4 and d15b7 bottom ends are suprisingly strong, and a few have managed to get them up to 9300rpm with any problems. the only thing that causes problems for a d series at those revs is the lack of oil squirters and the fact that its very easy to get an engine revving that high, but very difficult to get it to make power that high. but if you're taking it apart, i dont think there would be much difference between a d series and a b series, or any other straight 4 motor. just because parts are of different strength, doesnt mean that it will be more difficult (unless theyre forged together, thats a whole other ball game).

why i ask is cos i don't think paying someone else to build an engine for me, they would never take the time and the fuss as much as i would if i were to build it myself.

I would take my time and do everything right, researching and asking questions where i would be unsure. practicing on an el-cheapo D-series donk would give me a fair idea on how everything is put together and wouldn't matter if it were not done right.

i believe i am competent & confident enough to attempt this on my b18cr after i were to mess up a D donk first.

Thanks for all the helpful replies......:D

I couldn't agree with you more

[bennjamin]

all you need is an accurate torque wrench and a bunch of other basic tools -
