So my buddy has a (beautiful)... i might add..... white s2000 i was talking to him today to see what he has done to it and this is what he said.. he has low compression pistons(boost soon) and it is stroked but i dont know to what its stroked too. it might be an F24 engine now but i am not sure! then i asked him what ems he was running and he said it has a stock tune with no ems! but i thought to do these things you had to have some type of ems sooo i thought someone on here would know! so set me straight everyone!
