I know of a fella that got a recon unit and it lasted a week, the company at the other end suggested it was fitted wrong.
Personally i would go for a new one and stick it in myslef and save on labour.
if the recon turbo does go it can cause serious issues.
Garrett do not sell recon kits for their VNT units so this speaks volumes to me.
As Garrett dont make the kits they probably come from China which is bad news 9 times out of 10
