Ralco RZ lightened pulley - stock diameter *BELT SIZE*

[Fredoops]

More of a "for your information" as to which drive belt you should use for those stock size lightened pullies

For those who have Ralco RZ lightened pullies, those that are considered "STOCK DIAMETER"
ie: http://www.ralcorz.com/Ralco-RZ-914117.html

they are stock diameter for k20's not k24.Therefore you'll still need a slightly shorter drive belt because K20 stock pullies are slightly smaller.


Stock belt is 7PK1760 or 7pk1765

If you have a Lightened pulley, you'll need a 7PK1755, 5mm shorter.


PS: i run the pulley for 5 years now. no engine problems.

Do you drive your accord relatively hard, Fred?
V-tec rpm sort of driving?

I was the person who tested the reflash so yeah.

Thanks.
I'm hearing from you that the pulley replacement is second (after reflash) in term of bang for buck mods.

For an automatic, since you can't change flywheel the pulley is pretty much it in terms of changes you can immediately "feel"
