Why buy a TURBOSMART FPR?
We ensure that all Turbosmart FPRs are CNC machined in-house from billet aluminum and stainless steel, then hand-assembled and tested for maximum precision. Turbosmart FPRs are designed to provide smooth and stable fuel pressure under all conditions from idle to full throttle, and are suitable for use with both electric and mechanical fuel pumps. The FPR series features easy screw-and-lock adjustment and provides a stable 1:1 ratio between fuel pressure and manifold pressure. Each FPR comes with a variety of accessories, including fuel rail adapters, gauges, and fittings to suit the most popular makes and models.
What is a fuel pressure regulator?< span>
The job of a fuel pressure regulator is to maintain a constant fuel pressure above intake manifold pressure.
When do I need to install one?
To install high-performance fuel injectors or high-flow fuel pumps, you must use an aftermarket fuel pressure regulator that allows for pressure adjustment while maintaining a stable base pressure. They can also be used to maximize the ability of a standard fuel system to handle slight power modifications.
Before placing your order
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 you will not be charged any additional fees beyond the total amount paid at checkout.
〇Confirming compatibility
Our entire product database is based on North American vehicles (USDM), so please check whether the item can be installed on a Japanese vehicle (JDM) before ordering. (If you are unsure whether a listed product fits your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by choosing the year, manufacturer, and vehicle model in the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All products are 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 actual shipping cost may occasionally differ significantly from the automated calculation. In such cases, we will contact you individually by email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping within Japan, international shipping takes about 7 to 14 days, so please allow enough time for your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all items are transported via air freight. They are not shipped by sea.
○ Regarding compliance with Japanese vehicle inspection (Shaken)
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection system," and we cannot provide strength calculation documents or similar paperwork for these systems. 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 is a possibility of shipping damage to the packing boxes or products. Please understand that we will only handle returns, refunds, or exchanges for shipping-damaged items, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through us, warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
