How to make your turbo spool louder
This modification will give your turbocharger the classic jet spool/whistle sound that was found on the HKS T51R series turbochargers. The Billet insert not only looks amazing it also provides a unique look to your turbocharger. This upgrade will add an additional 3-4 days lead time before shipping back to you.
Process:
Step one: Send your front compressor to us. Address will be provided once payment has cleared.
Step two: Once received the front housing it will take 3-4 days to do the T51R Mod
Step three: Once the T51R Mod is done to your front compressor housing it will be sent back to you.
Shipping is charged because we have to send the turbo back to you via EXPRESS post.
