B20 myths.

[96Civ]

Well I'm just pulling this one out of my bum, but you probably won't need to resleeve for extra strength unless your going... over 10k? Does that sound right? Good R/S and walls on the B16 help, but I think it may cause premature wear on the engine I would like to know this one myself as well, maybe someone can fill us in?

But I would think you need extra cooling for a high reving engine as well.

[crxtacy]

thats what i figured. yes cooling would probley help. are the rods and crank different from the b16 to the b16b? they rev to 9k stock.

[96Civ]

You know... why am I the one that looks for the answers... why dont you go search some?

b16 = b16 The only real differences are the compression and cam profiles. Why would you put those into a b20 anyways?

I'm using a gsr tranny on my DOHC CRVtec and it works great. Actually I have it pulled right now to replace syncros and flywheel. But it has worked great so far.

Okay iam thinkin of gettin the b20 +b18c1 head , do u guys think id have a problem wiht the sleaves??? and if so i remmber seein some one say 10k for reslevin is that ture?!?!?

[96Civ]

10k? Yeah right! The engine isn't even worth that much!

You shouldn't have problems with the stock sleeves unless your boosting.

[JaydmCivic]

so what your saying is that if i resleeve it will be good as new?!?! no more problems with it ?!?!? because later on i plan to get a gen 3 turbo kkit

I did not say anything of the sort. I also have no idea the status of this 'block' so how can I answer that question?

[JaydmCivic]

okay here are the parts i plan to put on my B20b
WISECO IB spec 12.5:1 pistons
PROBE custom length rods
Tit. wrist pins
B16 pr3 head
CROWER titanium valvetrain
CROWER custom camshafts
CROWER oversize in/ex valves
NGK ignition wires
DC Sports header w/mod 2.5 collector
3" cat back mandrel bent exhaust w/turbo black apex canister
Fluidyne aluminum radiator
HONDATA s100 system
ITR intake manifold
RC 310 Injectors
AEBS fuel rail
GS-R S80 Trans.(open diff.)
ACT 6 puck clutch
prothane bushings
Endyn Breather kit
cold air intake
MSD external coil
SUN auto Hyperground kit
Oil Cooler/filter relocation

Should i need to resleeve it??!

[96Civ]

If you are going to be doing some serious turbo charging, yes. A resleeve is essential relentless of its condition.

[JaydmCivic]

okay thank you mr 96civic

sorry to bring up an old thread but if you are going to destroke the b20b go with atleast a b18c crank. a b16 crank in a b20b will not be 1.74 r/s, itll actually be 1.84, but you will need custom rods and you lose a lot of displacement. imo the crank should be left stock, longer rods will add more reciprocating weight, and the long stroke crank will allow for good displacement. remember rpm=faster wear on the motor. there is no need to destroke the motor to rev high, as long as you upgrade the necessary components(Rods, rod bolts, bearings, maybe a resleeve, and valvetrain) it will be fine. for example the formula atlantic/toyota 4age engine can rev to 11000rpm in built form, but has a r/s of 1.58; which is the same as the B18c.

no sir, you are wrong.

the B16A and B17A engines have a seperate block than all other DOHC B series engines, including the B16B. The deck heights themselves are different, thus, the b16b has a taller deck than the b16a, which means that it needs longer rods/taller pistons to achieve the same stroke.

Yes, definatly. It would only be a matter of time before the added compression from your 12:1 pistons blow out the walls.
