Hey everyone. I decided to buy a ap1 instead of a ap2 mainly to save money at the cost of the car. My only concern is the valve retainers I read about on these forums. Can anyone provide me with a list of all the parts I need for the valve retainer upgrade along with total costs of the upgrade? And also where to buy them from? Any other upgrades I need to do on an ap1?
I would be doing the work myself with the help of a mechanic.

Should I upgrade intake side with ap2 retainers and exhaust side with ap1 retainers? Do I need to buy keepers or springs?
Is the oil banjo bolt upgrade necessary for only daily driving?

I'll be looking at a 02 silver with 52k miles. Red interior!

Thanks in advance

 

Supertech seems to be the choice if you want to upgrade. Inlinepro make a nice set as well. All the information you need is here

also a helms manual wouldn't hurt to have. Run a search on valve retainers, its been covered thoroughly.
