Hi, can anyone tell me the standard nose pulley size that tha JRSC M45 kits come with, standard kit, not the big boost?

Thanks,

Jim

 

TDR has a good nose pulley RPM chart

Thanks for the tip, I have already been looking at that, I am planning on ordering new pulleys, but I want to know the stock pulley size so I know what ratios they run. I guess I'll just have to wait til my M45 arrives.

 

Sorry, I'd say that the stock is 77,5 mm. I can measure when I get to my car on saturday.

that would be great, thanks

 

Hi Jim!

As far as I could see, the pulley was 72 mm.

I always thought it was a 70mm. But then again, the first gen used like a 80 or 85 mm because the crank pulley was smaller. Depends what gen you have.

 

Sometimes it's a 72,5mm pulley (NA models) and other times (usually on NB's) 67,5mm. Hope it helps you. I have a NB and was looking for the 62,5mm pulley.

 

My kit arrived, it's for an NB, and has a 67.5mm nose pulley.

 

I'd just call Gary.
