FAQs - N55

Check out this page for answers to some of our most Frequently Asked Questions regarding our N55 kits. We will continue to update this page so check back often. (Last Updated: January 2022)

1. Do you have N55 kits in stock?

  • All of our kits are made to order and generally require a 4 to 6 week lead time, largely due to turbo availability from the manufacturer.

2. What are payment options?

  • You can purchase your kit through our website for shipping within the United States via credit card, paypal or Affirm. We also accept bank wire transfer. For wires and instructions, email jeff@speedtech.com or support@speedtech.com 

3. Do you ship overseas?

  • If you need to ship outside of the United States, we can ship direct to you. However, we recommend using a forwarding service in order to save on shipping costs. Due to size, weight and value of our kits, our overseas shipping rates are very costly. (www.MYUS.com is one of the forwarding services our current customers have used.)

4. How much do your kits cost?

5. How do I know what turbo to pick for the External Wastegate kit to achieve my whp goals?

  • For the N55 Bottom Mount kit there are many different options to choose from with a wide variety of hp capabilities. The figures on the HP charts are based on running e85 or similar octane fuel. If running pump gas only, we suggest multiplying these horsepower numbers by 0.70. This will help you determine what turbo kit will best fit your goals.

6. Do the N55 Turbo kits fit RHD cars?

  • No. Unfortunately, RHD fitment is not verified as we have only run our kits on LHD cars.

7. Will your N55 kits work on a N55 M235i?

  • Yes, N55 kit will fit a M235i chassis as it shares the same parts as the F30 chassis. 

8. Are your N55 kits compatible with a N55 135i?

  • Yes, our N55 kit will fit the E82 chassis. 

9. Will your N55 EFR kit fit a M2?

  • Yes, the N55 kit will work with the M2. 

10. Will the N55 kit fit a BMW 335i N55 xdrive?

  • It depends on chassis and desired turbo. Options for turbos for the F-Chassis xdrive are: Garrett, VSR or Precision. Options for turbos for the E-Chassis xdrive are: BorgWarner, Precision, VSR, or Garrett.

11. Will your N55 kits fit a 535i?

  • No, due to the differences from the 335i to 535i, our kit would need to be adapted in a few ways to fit the 535i.

12. Can I buy just a N55 manifold?

  • No, at this time we are not able to sell the manifold separately. Due to the rate of our manifold production, all manifolds are reserved for kits.

13. Can I buy a N55 kit without a turbo?

  • Yes, we have a N55 No Turbo Kit available. 

14. I saw a dyno of a hybrid Stage 2 and LPFP stage 2 with E-85 and it came out to like 460HP, will your kits make more HP than this? 

  • Yes, you'll make more power per psi with our kit than any hybrid option, as the turbo and our manifold are both sized correctly for 400-900hp options, as opposed to any hybrid with the small stock manifold. Our manifold cross sectional area is literally 3 times bigger than the stock manifold you'll find with the other options. See Below Image


 15. Do you have install instructions for your kits?

  • We provide full color instructions with the purchase of our kits and we are available for questions as well by emailing us at: jeff@speedtech.com or support@speedtech.com. Due to sensitive nature, we do not provide electronic copies.

DOWN PAYMENT TERMS & CONDITIONS (effective as of February 1, 2021)
Due to the varied and sometimes lengthy lead time on the turbochargers from the different manufacturers, SPEEDTECH offers a "Down Payment" option. Once we receive a Down Payment order, the customer specified turbocharger order is placed. When the turbocharger is received and the kit is ready to ship, a promo code is emailed to the customer to complete their kit purchase. Once a notification email has been sent requesting final payment with the accompanying promo code to deduct the down payment, payment needs to be made within 4 weeks. All kit orders need to be finalized in a timely manner. If final kit payment is not received within 4 weeks, the order will be canceled and the customer will be refunded their Down Payment minus 25%. 

If you have an issue with your turbocharger, all warranty issues are handled directly through the turbocharger manufacturer as SPEEDTECH does not modify the turbochargers in any way.

All hot-side parts (not including flexible couplers) come with a limited 12 month warranty and will be resolved on an individual basis by emailing us at support@speedtech.com. This guarantees SPEEDTECH parts to be free from manufacturing defects. Warranty applies to the original purchaser only.

At SPEEDTECH we stand behind the quality products that we sell. While most kit parts are interchangeable between their specific platforms, each kit is also tailored to the specific end user and includes customized components. If for some reason you want/need to return your turbo kit, the following will apply:

  • RETURNS: No Returns are allowed on any product after 30 days from the date you receive your purchase. To be eligible for a return, your purchase must be unused and in the same condition and original packaging as when you received it. All returns require a Return Materials Authorization (RMA) and a receipt or proof of purchase. Email support@speedtech.com for return details and to receive your RMA number. If you do not have a RMA number, your return will be marked return to sender and your return will not be processed. You will be responsible for paying for your own shipping costs for returning your Service. Shipping costs are non-refundable. We cannot guarantee that we will receive your returned item and therefore, due to the high value of all products, you are required to purchase shipping insurance for returns and you must use a trackable shipping service. If your return is not received and a claim cannot be filed due to lack of a tracking number and/or shipping insurance, you will not be issued a refund. As all products are made to order a 25% restocking fee applies to all returns.
  • REFUNDS: Refunds (if applicable) Once your return is received and inspected, we will send you an email to notify you that we have received your returned item. We will also notify you of the approval or rejection of your refund. If you are approved, your refund will be processed, minus the 25% restocking fee that applies to all refunds and a credit will be issued to your original method of payment, within 10 business days.
  • CANCELLATION: If for any reason you wish to cancel your order before your Service has shipped, you will be issued a refund minus a 25% restocking fee. If your Service purchased was a "turbo kit" and you paid in full, you will receive a refund minus 25% off the cost of the turbocharger. If you purchased a down payment toward a turbo kit, you will be issued a refund minus 25% from the cost of the down payment. Once your Service has shipped, the order cannot be cancelled, refer to Return policy above.
