No, all of our kits are made to order and generally require a 3 to 12 week lead time, largely due to turbo availability from the manufacturer. With supply chain issues, longer lead times may result.

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 in the Tech Info section 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.

Check out the Tech Info page for HP comparison charts to help in turbo selection. 

BorgWarner SX-E: oil cooled/journal bearing. With a journal bearing turbo, you will see a slightly slower spool up transition compared to the ball bearing Garrett G or GTX or Precision Gen2, but the SXE is a good reliable turbo for HP per dollar.

Garrett G-Series or GTX line - One of the best options for reliability and performance, but priced accordingly. Water cooled, ball bearing, great materials and quality. If you plan to ever road race your car, these are a great choice.

Precision - Great performing turbos, usually one of the highest HP per comp wheel size. These are oil cooled like the BW SXE, but the Precision line has options of journal or ball bearing, you'll pay more for the ball bearing (noted as "Gen 2") turbos vs journal bearing. 

VS Racing - One of the better low cost options. These have been very popular in the LS world. Note - the ones on our list are all single scroll turbine housings, compared to the rest on our list come in twin scroll, so a bit more lag compared to the twin scroll options.

N55 BOTTOM MOUNT RECOMMENDED:
Exhaust Donuts - Manifold to Head 
Downpipe to Exhaust Gasket - or Permatex Ultra Copper works well instead (E-Chassis only)
Loctite 565 Thread Sealant (Precision or BorgWarner Turbo only)
Drivers side charge pipe with BOV

N55 BOTTOM MOUNT OPTIONAL:
Boost Controller
New Spark Plugs
Upgraded Intercooler
Fueling Upgrades

NO TURBO KIT: Yes, we have N55 No Turbo Kits available. See the store for more information.

*Please Note: if you are sourcing your own BorgWarner SXE turbo, the turbine housing will need the 3" v-band outlet, NOT the standard Marmon flange. The v-band mating face should be roughly on the same plane as the rear surface of the T4 flange. If the v-band position is located differently, you may find alignment issues with the downpipe.

MANIFOLD ONLY: 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.

We offer a military discount. To receive this discount, email us a photocopy of your military id and we will issue you a promo code.

Shops - email us for information.

Beyond that, our kits are heavily discounted already so no further discounts are currently offered.

Yes, we provide full color instructions with the purchase of our N54 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 offer electronic copies.

* E-Chassis and F-Chassis kits have significant differences. See kit photos in our store for more information. An E-Chassis kit will not fit an F-Chassis car and vice-versa. It is not recommended or cost effective to purchase an E-Chassis kit and adapt it to an F-Chassis car and vice-versa.

Most Speedtech parts are common between the different turbo manufacturers, however the following parts are specific to the turbo and/or vehicle specifications the kit was built for: 

* Recirculating Wastegate Pipe
* Bottom Mount Kit RH motor mount (differs between AWD and RWD, E/F-Chassis)
* Oil feed line/fittings and oil drain block

Therefore, if you purchase a secondhand kit that was built for a BorgWarner turbo, the above parts will be different if you switch to a Precision, Garrett or VSR turbo and vice-versa. 

Example #1: If you purchase a E-Chassis Bottom Mount Recirculating kit that was built for a Precision and are switching to a Borgwarner, Garrett, VSR or vice-versa, the recirculating wastegate pipe fitment will NOT line up properly. Note that the flex couplers in both the wastegate and down pipes are not meant to accommodate this improper fitment.

Example #2: If you purchase a Bottom Mount F-Chassis kit that has a RH motormount for a RWD car, and you have an AWD car; the RH motormount will not fit.

Example #3: If you purchase a kit built for a Precision and are upgrading to a Garrett turbo, the oil feed line/fittings and oil drain block will be different. You will also be missing the coolant line/fittings. 

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.

No. Cast manifolds (both coated and un-coated) should NOT be wrapped, as it can cause hotspots and cracking

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

Yes, our N55 Bottom Mount kit will fit the E82 chassis. 

Yes, the N55 Precision, VSR or Garrett kit options will work with the M2. 

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.

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.

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

There are many options to choose from for our N55 kits for which the price fluctuates.

The Speedtech N55 Bottom Mount Kit pricing will vary depending on the turbo, recirculating or open dump setup, and wastegate selections. See our Store for specific pricing based on the turbo kit of your choice. You can select different options and the price will adjust. 

All purchases are made through our website. You can purchase the kit in full or purchase a down payment (price varies based on turbo selection) to get the turbo ordered, with the remainder due prior to shipping. *refer to Down Payments terms & conditions

Payment options are credit card or Affirm.

Payment options through Affirm are subject to an eligibility check and are provided by these lending partners: affirm.com/lenders.

Lead time on a kit varies based on turbo availability and can be anywhere from 2 to 12 weeks generally. As we do not stock turbos but rather order them per the customer specifications when an order is received, we cannot control the turbo availability or lead time.

Current lead times are subject to change based on turbo availability.

Lead times on any kit may be longer or shorter depending on the turbo.

For BorgWarner or Precision Turbo Complete Kit purchases shipping to an address in the United States (not a forwarding service), the turbo will drop ship direct to the customer and arrive separately from the remainder of the kit. As a result, you will receive your turbo before or after the remainder of the kit. 

2. For Garrett and VSR Complete kit purchases, the complete kit will ship in 1 box.

WE DO NOT SHIP KITS TO CALIFORNIA.

Products are not for sale or street use in California & other states following the California Emissions Standards.

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%. 

TURBOCHARGER WARRANTY
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.

SPEEDTECH MANUFACTURED PARTS
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.

RETURN/CANCELLATION POLICY
At SPEEDTECH we stand behind the quality products that we sell. While many 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%. 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. We do not stock turbochargers but order them per the customer specification and order. Therefore, we do not have any control over the lead time of the turbocharger from the manufacturer which can in some cases be lengthy. Once a turbocharger has been ordered for a customer and is in process, it cannot be changed and/or canceled without incurring fees. Effective as of November 2022, if you order a complete turbo kit and cancel the turbo order for any reason, you will be charged a 25% restocking fee on the cost of the turbo. 

* FOR ALL ORDERS, IF BILLING AND SHIPPING ADDRESSES ARE NOT THE SAME, YOUR ORDER WILL BE CANCELED.

The only exception is for international customers using a forwarding service. Your billing address will be your international/home address and the shipping address will be the forwarding service (i.e. MYUS).
