Notes:

1. This is a service and not a product. The listing is for having your own turbo converted with a T51R mod, not to receive a pre-made product.
2. First thing you need to do is get into contact with us if you want the T51R modification. This configuration is known to work on 2-port (A90) and 6-port (A91) GR Supras.
3. If your turbo is deemed possible to modify and you want to move forward, the typical turn around manufacturing time is 2 to 3 weeks AFTER the turbo is received through shipping.
4. We do not carry usually cores in stock, so you'd need to send a core or remove and ship your turbo housing for modification; will add roughly 7 to 10 days to process as we await delivery.
5. However, we sometimes have cores available, so please email in for core availability.
6. If your turbo does not have an anti-surge cavity already we will need you to provide us with a measurement BEFORE you remove the housing from your turbo. Please message for more information.

Unique Turbo Noise On A Budget!

New to Speed Industry, this item is an excellent and ingenious solution to creating more turbo noise without breaking the bank. It's essentially a modified turbo housing with extra beveling inside and a new insert designed to recreate the iconic whistling and wooshing sounds of the HKS T51R.

Features:

• Upgraded sound in a relatively simple package that doesn't break the bank
• Achieves sound via modified internals within the factory housing
• Minor beveling inside housing
• New inserts for redirecting airflow to generate turbo whistle
• NOT intended for power increases
