Morrie's is saying that the stock STI turbo has two different part numbers, one was made from january to mid june and then from mid june on. My question is whats difference?? the two part numbers are: 14411AA572 14411AA620 need to replace my turbo in my 06 WRX wagon. I have the VF-39 in it (stock 06 STI right)? Morrie's did not understand VF-39.. They quoted me $907. Thanks Will
The second part number is the vf43 Here Will, you got nothing but time for the next few weeks, right? http://www.iwsti.com/forums/2-5-lit...39-04-06-sti-vs-vf43-07-sti-myths-busted.html (CN: wastegate actuator is the biggest performance oriented difference)
