Thoughts on Stroked B16.....
 

I am wondering what you people think about stroker kits??

Not worth it... B16's have an almost perfect r/s ratio...why ruin that?

If you want a 1.8L engine go and buy a 1.8L engine.

you stroke that thing and it won't safely rev as high...

Thanks for the feed back

not to mention the sheer expense of stroking it

huh???
:confused:

by stroking the engine your changing the rod to stroke ratio... by reducing this ratio (to get more displacement) you create a rod to stroke ratio that will increase the pressure placed on the side walls of the cylinder, as the rpm increases so does that pressure and ...crapit's late and this is getting to long here's a simple way of looking at it

cylinder sidwall pressure of stock B16A will equal a certain value at reline lets call this value X

if the b16A is then stroked to say 1.8 liters then the sidewall pressure increases at the redline (actually it increases thoroughout the power band) X goes up

if you destroke the b16 then the rod to stroke ratio is increased and the pressure on the side walls decreases X goes down

ok so what does all that have to do with my statment of not reving as high, well there is a certain pressure that when applied to cylinder walls they will crack or split or explode or some nasty like that....anyways this set pressure point on a stroked engine will be reached sooner then on a non stroked engine (assume you have no red line and could rev to that point on a non stroked engine) on the stroked engine without re adjusting and lowering your red line you run the risk of reducing that safety factor and distroying the engine.

just my 2 cents

Well thanks for the tips...
