Customer Questions


Is this compatible for a 2012 ACURA TSX base model 2.4L k24z3? If I buy this and install it, do I need to reflash or buy hondata also?


This kit would fit on your TSX's engine, and no reflash or tuning is going to be needed.


Is everything stock size?


These pulleys are a smaller size than the standard pulleys are.


What pulleys come in the kit for 04-08 TSX? Can I use or buy just the alternator and PS pulley and idler without using the crank pulley?


This kit includes the three pulleys you mentioned, minus the idler pulley. Unfortunately we are unable to delete pulleys from the kit.

Q:Will this be reliable for daily driving?

Yes, it will be.

Q:Hi i have a 9gen si with kraftwerks supercharger 110mm pulley making around 11.5psi, would my civic benefit from the crank pulley(make more power and boost)?

No, this kit has an underdrive pulley and because of that it will slow your belt drive and lower your boost. You don't want this kit on a supercharged engine.

Q:Did you know the diameter of the crank pulley of this kit?
A:The crank pulley in this kit is 124mm in diameter.
