dont really know the year of the tranny or motor...... bought the car with the swap allready in it.... from google it says the S1 is a JDM B16A X-Si. dont know the year.... motor in my car is a B18A1.. also dont know the year! I know its not much help for you guys but... just want to know if its worth it to do the Gsr tranny in my hatch. cause the clutch for it is like 288.00 at advance auto partS! so it might just be worth it to buy another B16 tranny!
