LS cracnkshaft in B16

[b18delsol]

does anyone know if a integra LS crankshaft will fit a USDM B16A2 motor?

 

[projectxspeed]

physical it will fit but you will have to get new pistons and rods + I dunno what bottom end parts you would use

 

[projectxspeed]

Why do you want a LS crank anyways?

I am pretty sure you need to notch the block and remove the oil squirters in order to do this.

The idea would be to get the stroke of an LS/vtec, but keep the stronger bottom end of the vtec engines.

 

[foolish]

it will go. But like said up there. The stroke is to long, you need custom rods. pistons r ok. i think a b17 will work with out a problem. The b16 block is .38 I belive smaller then a b18/20 block The b17 block and the b16 block are the same!

How would the bottom end of a b16a be any stronger than a b18a bottom end? They are almost identical, except for the deck height. Just keep the b18a block and get a block girdle, something else b16a's and b18a's did not come with. That will stabilize the bottom end substantially, then just go get a vtec oil pump, and you're in good shape.

it can't be done using OEM honda parts.

with ls rods, it will hit the head
with b16 rods, it will sitll hit the head.

rememebr, the deck of the b16 is physically shorter than gsr/ls blocks

You just listed one huge reason, the block girdle

Oil squirters is another, if you are running a street motor

better oil pump

I beleave the vtec rods can use wider bearings

the list goes on

The b16 does not have a block girdle.....only because of its R/S ratio

I did not know that, thanks.

use a b17 crank in a b20.
