Spoon/Toda 1800cc stroker kits


During the initial assembly when the motor is brand new at Honda, the full balancing treatment is present.

But when you go purchase these bits and pieces individually, they are not balanced anymore.

Have you driven a motor that has had the internals fully balanced? Well yes you have, because you own a Type-R. Really, to say that there's not much difference .... then I suppose Honda and others in motorsports divisions made the mistake of having their competition variants assembled in such a manner.

In short, if one were to follow or go beyond the Honda benchmark, you would opt to have your rotating assembly dynamically balanced - crank, rods, pistons, crank pulley and let's not forget the clutch (pressure plate, disc, flywheel)
 
HEY!
spoon, toda, whatever!
has anybody ever heard of the Brian Cower storker kit!

yeh if you put it that way, makes sense since they are assembled ITR parts. But then if we change our flywheel, clutch, pulleys etc etc, we are already throwing everything off correct?

Honda doesn't go that far to dynamically balance which is why I do it to flywheels and clutches when I replace them.

I don't change to crank pulley, unless it's lightening the stock one or using one from ATI or Fluidampr. Accessory pulleys I would consider.

hmm interesting... What about when we alter cams, valve springs etc etc? All these things affect too right?
 
their significance is not as pronounced as the heavy rotating assembly.
 
so if u were to fit the stroker kit what else would u have to do after u have fitted it?

like said/ it would be better with an alteration map although stock ECU can handle the fueling even when stroked....

I would say larger throttle body/DC2 inlet mani or aftermarket mani of some sort....

Not essentials but i would say would make the engine flow better....

After reading this, im sure after installing the stroker kit it has slightly higher compression then a b18C engine? I could be wrong, so please correct me if so....
 
same compression.

you can't get more compression when you're using the same internals as the B18C.

It will bump a bit more if you go OS pistons or use a 2pce gasket or have the head machined or the deck of the block machined.

I thought maybe the headgasket provided in the spoon kit was slightly thinner.... Also they do advise a bit of machine work when doing the build, and with the slight overbore?
 
no crank girdle.

no oil squirters

no OEM oil cooler

no high flow oil pump

not the right water pump

no high compression pistons

though it would make sense to run the B18B crank for some more displacement in a B18C
