The ISR Stainless Steel Braided Turbo Line is a direct replacement for the factory turbo hard lines found on S13, S14, and S15 SR20DET (T25/T28) turbos. It uses high-quality aircraft-grade fittings and comes with new aluminum washers.

The new ISR lines utilize state-of-the-art racing hose with a pre-dyed black Nomex cover to ensure maximum performance and a consistent, fade-resistant appearance. Adding Kevlar to the flame-retardant Nomex cover increases abrasion resistance and overall hose strength. It provides a smooth, firm, and high-performance inner tube. The hose assembly is up to 45% lighter than traditional high-performance racing assemblies. It uses black nylon-reinforced synthetic rubber and a lightweight outer textile fiber braid.

These lines provide a truly clean look to your engine bay.
Compatibility:

  • S14 SR20DET
  • Bottom mount turbo

Legal only for use on competition vehicles that are not registered or licensed and cannot be used on public roads or highways. May also be used on other exempt vehicles.


Before Ordering

〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.

Compatibility Confirmation
Since our entire product database is based on North American vehicles (USDM), please confirm the compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure whether the listed product fits your vehicle, please feel free to contact us. Our support team will be happy to check for you.)
If you place an order without confirming compatibility, we cannot accept returns due to fitment issues.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model on the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.

○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the amount calculated automatically. In such cases, we will contact you individually via email.

All products are generally shipped internationally from our US warehouse. Unlike domestic Japanese shipping, international shipping takes approximately 7 to 14 days, so please allow sufficient time when placing your order. If you are in a hurry, please inquire about delivery times in advance. Note that all products are transported by air. They are never shipped by sea freight.

○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese vehicle inspection system," and we are unable to provide strength study documents or similar certifications for this system. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.

○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacements for damaged, defective, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through us, all warranty-related matters will be handled "exclusively through us." Please note that we do not coordinate with other companies or agencies located within Japan.
