What else needs to be updated to run R134a.
You need to make ONE adjustment to make your current (OE) system work with R134a. Follow this link:

It is WAY cheaper making your OE system work with R134a than to purchase an aftermarket system.
Do the procedure in the link above then:
Replace all your o-rings (approximately $10 at ackits)
Purchase a new receiver/dryer (about $40)
New hose assembly ($90 or so from LMC or other)
Get R134a at Wal*Mart. $3-$12/can. Get 4.
Purchase a bottle of R134a compatible oil - ackits has this on their website.

Flush everything. Fill everything with oil. The service manual tells you how much. Total is 10-12 ounces.

Evacuate the system. Fill with R134a. Use your extra $900 you saved over an aftermarket system to buy some really cool wheels or start paying on your kid's orthodontist bill.

I don't work for ackits, LMC, or Wal*Mart
