I saw somewhere someone selling a crank for the S2000 stating it was for a 2.4 stroker engine with stock bore. I was wondering what is needed to do a good reliable 2.4 stroker engine? Is a huge pile of cash and time needed for that? If so it's not for me but going through my options now as I want some more power and torque and thinking between stroker or turbo/sc kits.

At an 87mm bore you would need a 99mm crank to make it 2354ccs

I highly doubt you can turn out a s2k crank that far.

You can modify a k24 crank to work , they are 99mm . .

The crank he is talking about is a 99mm Castillo crank someone is selling in the classifieds. The cost to build it would be the same as any built engine but with the additional cost of the crank. You will need new bearings, rods, and new pistons unless you source aftermarket rods with the OEM wrist pin size. This plus the cost of labor to assemble the engine unless you have that talent.

Yeah that is the crank I saw. How reliable is a 2.4 stroker assuming a good tune? Would it be less reliable than stock 2.0L? Do you know which pistons, rods etc I would need to get for a 2.4 build?

Call Castillo they make appropriate rods for that exact crank

Ok cool. Thanks. Seems like this might be a less expensive route than going with a turbo or something. Won't get as much power but will have a rebuilt engine plus lots more torque and power and still be NA.

Honestly all said and done its much more cost effective to go turbo or SC but NA is always a fun but overall costly route to go.

yeah i would have thought that going boost is the cheap and easy alternative to a fully built engine not vice versa.

Hmm everyone talks about it being like $10,000 for a full tubo set up. I don't see how it could possibly cost near that to get an engine rebuild and stroking it at the same time... Sure I would need ems and fuel injectors and pump so figure another 1500 at the most for fuel there and then maybe $500 for tuning or so.

Look at this article. It's where everyone got the idea.. You source the parts and you figure out the prices.
