i was thinking of getting some new pulley(Unorthodox Racing) to lighten the load of my engine, and of course gain some hp.

i have a 03 wrx, and my timing belt is due soon so was thinking of just buying some pulley(s).


In addition, is it worth buying a pulley kit in the long run and what are the pro's and cons of getting them.

Pros:






Cons:

 

Con: they will give you a CEL if you have a lightweight flywheel for misfires

 

dont do it

 

I don't know a lot about the specifics of the different pulleys, but I've had a Vishnu pulley on my engine since it went in 5 years ago. I have not had any issues whatsoever related to the pulley.

Honestly, I would just save you money for something else.

 

A lightweight is fine. Just not too light. Don't go underdriven.

Possibility of throwing a CEL especially with a light flywheel.

Pros: waste of money for some bling






Cons: dont do it

 

Waste of money x 10000


You will notice ZERO difference and run the risk of various problems. Underdrive pulleys are the worst so def stay away, and the light weight versions are just a waste of money all together.

Get a lighter weight flywheel instead.

 

I've had a Perrin pulley for about 4 years now. I felt like my car lost 34.5 lbs... Weight reduction stage .5 sup.

 

You felt as though your car lost weight? How?


I can't tell if that was sarcasm or not...

 

Its sarcasm. The weight reduction "Stage .5" part gives it away.

 

Don't buy trouble. In regard to buying lighter flywheel suggestion above, avoid that too. It will be way too noisy for ej20.

 

5 bucks says he's still gonna buy it

 

You are in the 310?
