Underdrive OEM style. Note the size of the pulleys. The one in the center is the smallest and lightest. The one on the right is almost as small but not as light, but still lighter the stock pulley. No dyno result yet to determine the difference but the engine seems to perform well.

 

wow, nice!

 

so why you switching out the UR pulley

 

What pulleys are those? (not the UR ones)

If you switch out are you going to be selling your UR pulleys? I'll take them off your hands.

 

So your butt dyno doesn't notice any difference?

What about car accessories and AC? Any difference there?

 

what are the results and impressions on the new pulleys?

 

Nice shots, thanks for the info. Should improve throttle response.

 

PRC/ITR pulley?

 

Yes, it's the PRC/ITR pulley. Since the sizing is very close to the UR crank pulley and I'm still using the UR alternator, and PS pulleys, there isn't much difference in alternator output. I just wanted to test out another pulley option. That's all.

Btw, the weather has been terrible in Seattle so I didn't get a chance to push it much to see the real difference. I thought it seems slightly quieter inside the car with the ITR pulley perhaps due to the elastomer.

 

where can you get those pulleys? and what's the price difference between the the UR and the PRC/ITR pulleys?

 

you can order the PRC pulley from any acura parts dealer, it's stock on i think 05+ RSX.

the difference is it has the rubber damper ring elastomer or whatever in it still. It's also significantly heavier, but still lighter and smaller than stock.

 

there wont be any rain tomorrow

 

Humm...$142.00 USD approx. for the RSX Crank Shaft Pulley? That's kinda steep. But it would go a long way towards helping me with the following dilemma:

 

The pulley is JDM K20a or 05-06 RSX-S. The standard RSX has a different size pulley.

 

sorry i didn't say type-s cause i figure no one ever wants anything off the base RSX anyways.

 

WoW, lets us know what sup!

 

on a scale of 1-10 how hard was it to install, and do you need any special tools like a torque wrench?

 

Uh oh I think JTso is collecting more stuff like he did with shift knobs

 

Give us an idea of what a 10 is for you. Is a 10 a tranny swap or a brake job?

 

so the whole set is more expensive than the UR pulley?

 

lol brake job a 10. That must make pumping gas a 3 or 4.

 

Any more impressions of the pulleys JTso?

 

Any update on this?

Thanks!!

 

Hmm... I don't have anything new to update. It's basically a smaller stock style pulley which allows the engine to spin easier.

 

So did you change it back to UR pulleys or still got that set up?

 

I have the ITR pulley plus the UR power steering and alternator pulleys.

 

hey jt, do you have the pulley belt part number? i'm doing a type s pulley swap in my friend 06 tsx. we tried to use the rsx belt but that thing was too tight. he told me you have the part number and have listed it on here before. but i'm having a hard time finding it.

 

If you are installing the UR pulleys, the part number for the Gate's belt is K070683.

 

or the Gatorback Poly-V 4070685. These belts are spec for a 02+ CR-V

 

Hi!

Does anyone know the weight of the stock TSX crank pulley?

How about the diameter (side to side)?

Thanks!
