Are there any underdrive pullies available?
Unorthodox Racing makes underdrive pullies however it is not recommended to
use any underdrive crank pullies from any company at all because it can cause
oil pump failures. All Protege engines are directly crank driven and if an under-
drive crank pulley is used, it can cause accelerated wear in it which will event-
ually lead to failure! Typical underdrive crank pullies do not have a harmonic
balancer and therefore all the oscillating forces from the crankshaft are
transmitted elsewhere. Even on the typically well balanced stock crankshafts,
there is always a very slight imbalance in them and as such the forces caused by
them results in the oscillations. Many turbo Miata engines have blown up from
oil pump failures due to the installation of underdrive crank pullies. Be warned!




guy's is this true?

I think Gatorback belts are the recommended ones. Do a search and you will find the part #

As for that other junk, it is probably BS.
 
Do it. A good mod - esp. if you can find one used/cheap.
Yes, you ned the new (smaller) belts.

I needed to re-torque the belts twice to stop squealing - but they were pretty loose...

Hmmm...Interesting.

The link is little over a year old, but if you click it & scroll to the bottom, they still have the UDP for the Proteges for $90 + $10 Shipping. I'm thinking of buying it and see what happens... If I pay by paypal/credit card. I can save the link and argue about it with my credit card company for false advertisement!? lol!

WiL

EDIT: If you go directly to www.rr-racing.com and click the "crank pulleys" link, the price is $138 + $10 shipping.

Argue all you want but you have to realize your looking at the BULK BUY page so don't shoot yourself in the foot just yet. RR offered me the same price if I bought a bunch at the same time.

Oh well, it would of been nice.

EDIT: How many would be considered BULK BUY? Maybe there's more new Protege owners that might want one?

It looks like lots of others want one also. You should try to set up another group buy with RR Racing. Ask for Rafi
