is it worth it, yes and no. what motor do you have. if you have a B16, i could see a Eagle Crank that would stroke the motor to 1.8 being worth it. but the cost of a Eagle crank is roughly 800$. for $200 more you can sleeve it to 84.5mm and have a 1.8l that retains the B16 crank and the 1.56 rod stroke ratio= a 1.8 liter that can rev fast and reliably. A stroker crank can cause rod/stroke issues, and accelerated bearing wear isues do to the extra stroke. be sure tyo use forged internals.

I personally do not like stroker kits, i would rather sleeve the block. if you want discplacement, i would look at GE Sleeves out to 84mm before i did a stroker motor.

now if you got money, you can do TRICK setups with stroker kits like long rod to keep the pistons speed down , tall deck block, etc. but thats $$
