I have been reading lot of threads on pulleys for our second gen tsx. People have strong opinions when it comes to aftermarket pulleys. And if installing a pulley is good or bad, have been debated extensively in many forums and I don't want people to start that debate here. I'm thinking of gambling on installing pulleys for my 2013 TSX AT. I would like to put either just stock diameter crank pulley or stock diameter pulley kit. I'm not sold on the underdrive kits because of the potential negative imapacts even tho they may give better HP gains.

My question is to people who have done this mod. What pulley did you use? What kind of performance gain are you seeing and are you happy with it? Any tradeoffs? I couldn't find a stock crank pulley from UR. Can you suggest other brands? I see that Ralco has 6061 Aluminum lightweight pulley kit on stock size, but people have been bitchin about their poor quality. Anyone using Ralco got any feedbacks?

And if these questions have been answered in a different thread, I would appreciate if someone can send me a link to that thread as I couldn't find it.

Thanks in advance for any help.

I don't think they sell stock diameter crank pulley anymore. Correct me if I'm wrong.

Do you have stock dia pulley installed on your tsx?

Hey there, I'll throw in my 2 cents because you mentioned the Ralco kit. I picked up a set for my 8th gen civic about 2 years ago and it was a 3 thousand dollar mistake.

I wish I had some pictures for reference but my phone I had at the time died. I'll try to keep this to the point...

If you ever see a stock crank pulley, you'll notice it is all one piece, the crank itself and the small extension that inserts into the engine block itself. On the Ralco kits these two pieces are separate and the only thing keeping them in sync is a small metal insert that sits into a cut out groove between the two. So as the power of your engine is transferred through the crank pulley and out to the serpentine belt, all of that torque is managed by a tiny rectangular piece of metal wedged between the two pieces. Long story short the power of the engine warped that little metal rectangular piece, the timing of the engine skipped, there was a horrible loud metal crash sound and my poor engine chewed itself apart from the inside out.

I'm in no way trying to sway anyone from a pulley kit, hell I've been eyeing the Buddy club kit for the k24 in my TSX. But I thought I would just share my experience with the Ralco kit, and I'm sure there are obviously thousands of people out there with aftermarket pulley kits who would swear by them.
