ISR Performance has added a large-frame turbocharger to its turbocharger line. Building on the quality and success of our popular small T2 replacement turbochargers for the SR20DET engine, we have added larger-frame turbos for users seeking more power and those looking to combine ISR turbos with top-mount manifolds for not only SR, but also KA, RB, and JZ engines. This turbo is equipped with dual ball bearings and a billet compressor wheel, delivering quick spooling and efficient power.
This turbocharger provides big power and excellent response with proven quality. This turbo features a 90mm V-band discharge flange.

Before Ordering
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred during import on our end, so there will be no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
All product databases are based on North American vehicles (USDM), so please check the compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our homepage, it 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 payment. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the automatic shipping calculation may occasionally differ significantly from the actual shipping cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with sufficient time to spare. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air freight. They are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically all designed and manufactured outside of Japan. Please note that they are not adapted to the "Japanese Vehicle Inspection System" in any way, and we cannot issue strength calculation documents or the like for the Japanese vehicle inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, 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 may be delivery damage to the packing boxes or products. Please understand that we will only provide returns, refunds, or replacement exchanges for products with delivery damage, defective products, or products different from what was ordered if you contact us within 7 days of receipt. Please note that for products sold through us, warranty support will only be handled "exclusively through us." We do not provide support through other companies or agencies located within Japan.
