i need to know the toque pattern for crank and head also how much to torque them pics will help

 

bump

 

its all the same as the ls engine torque specs.... its the same engine... b20b and b18b are identical except the b20 is bored to 2.0 liter... so jsut use all the same torque specs.

they are not identical, the blocks have different castings.

the torque sequence starts with the inside 2, then moves outward.

9...3...1...6...8
7...5...2...4...10

I hope that helps...

different castings.......


PARDON!?

how so?

 

considering this thread is about the torque specs for the head and not for the casting of a block im going to tell you do the what most HT members would... SEARCH

 

are you telling me to search? or the guy who made this thread who should have searched in the firstplace?

your too funny..... i bet you said that and now your like oh ****... he wants me to back up my bull....

 

here you go. enjoy your freebie. search next time.

this is correct tightening pattern

the torque sequence starts with the inside 2, then moves outward.

9...3...1...6...8
7...5...2...4...10

I hope that helps...

Also when you tighten dont just tighten it to 61lbs. do a step tightening... meaning tighten to like 20lbs first. all the bolts. then 40lbs all the bolts... then 50lbs all the bolts... then 61lbs.... the more stepped you do it the better. but dont waste too much time.

The B20 is not a bored out LS motor, it has a completely different sleeve design the the other b-series motors.

 

thanks guy great help how about crankshaft

thanks, anything else LordAphotic...?

About the main caps you'll need to torque to 22ft lbs. then to 56 ft lbs. in 2 step sequence. Without going to my garage and getting my service manual, I would assume the sequence starts in the middle and works itself outward alternating left and right sides...

Good luick

 

thanks to all of u

so the sleeves are designed slightly different.... cause they are obviously bored too much...... but the sleeves being different was given being that its a 2.0 liter engine originally designed to be no bigger than a 1.8 liter. other than that difference everything else is the same.

ill admit i didnt know the sleeves were finned for more structural integrity... though it doesnt seem to help much.... but ill give you points for prooving me wrong on the sleeves though it was the other guy who posted it. atleast now i know you werent totally bs'ing me.

its still a bored out b18b.

The sleeves on the B20 are actually thicker than the B18 sleeves, so I don't see how it is a bored out B18. You can pull the heads off both motors and measure if you want.

 

no they arent. i have both engines and have opened up both engines. they are noticeably thinner. especially inbetween cylinders. its a bored out b18b

 

the b20 is not a good motor its good for one thing if u blow ur b18b or a its a nice replacemnt with a slight bit more tourqe plus i dont think u can pass inspection wit ha suv motor in a car i herd that somewhere

Your right, the walls are thinner "between" the cylinders, but it's not a bored out B18. I know there are threads floating around with pictures comparing the b18 and b20 somewhere, couldn't find them after searchign though. Read that article I posted...

"The B18B's 1834-cc capacity was obtained by stroking the B16A to 89 mm. Further enlargement to a planned 2.0-L capacity could only be achieved by increasing the bore of the B18B, however, the engine's high-pressure die cast aluminum block with separate iron liners left no room for such enlargement. Thus the development of a new one-piece cast liner unit with four integrally cast cylinder liners came about, which Honda describes as "consecutive liner construction," or "quad-sequential sleeve block." It is more like Siamese-quadruplets. With this liner construction, the web distance, or distance between the inner walls of the adjoining cylinders, could be reduced to 6 mm from the separate lines' 9 mm, while retaining the same bore pitch."

Shut the expletive up. How is it not a good motor? Becuase it doesnt have vtec? ******* ****.

its a good replaicment motor nothing else why would anyone go from a b18b to a b20 there is hardly any difference if there even is a difference plus u cant even use it cause u wont pass inspection with a SUV motor in a car these are all factors why the b20 is nothing but a replaicment motor

 

it is a good replacement engine... i wouldnt spend the money to buy one if i had a good condition b18b.. only cause with the money id spend i could make that b18b a hell of a lot faster with a vtec head or something.....

but the b20 is a much better platform then the b18b.... the specs are similar... but the difference is where the power is placed.... the b18b gets most of its power after like 5000 rpms the b20 starts lunging into power after about 3500 and although they end up having similar power the b20 gets into it a lot sooner.

plus with mods the b20 will always make a hell of a lot more power with those .2liters of displacement... makes a world of difference.

in california and some other states it will not pass visual because it is classified as a suv engine... which is stupid cause like i said before... its just a bored out b18b..... but if you can get crooked smogs then its worth it... i currently own two g3 integras both with a b20 in it. mines a b20 turbo and the other is a daily driver b20 stock.

youd be suprised on how much a b20b will pull on a b18b... the ls intake manifold is one of the best stock flowing manifolds.. it does wonders for the b20.

</TD></TR></TABLE>

Just because it has 0.2L more displacement and the powerband is different doesn't make it a better platform. The B18a/b, B16, B18c motors are by far better platforms than the b20. That article I posted explains the b20 sleeve design pretty well and there is plenty more info floating around backing up that article. The sleeves on the B20's are junk, they cracked on me, and have cracked on a few of my friends setups, and yes the motors were all tuned very well. It's kinda hit or miss with these motors from what I have experianced, some have been fine with forced induction setups for a while, yet some b20's have cracked while they were still stock in the CRV's.
