GENERAL FAQ'S

Yes, our N55 Top Mount kit fits the F87 non-competition cars and our S55 Top Mount kit fits the F87 competition cars.

No, all kits are built to order, regardless of if you order through us or a reseller/dealer/shop/on-line store.

ALL SPEEDTECH TURBO KITS ARE BUILT TO ORDER AND SHIPPED BY US. ALL ACCESSORY ITEMS ARE SHIPPED BY US. NO RESELLERS/DEALERS/SHOPS/ON-LINE STORES STOCK SPEEDTECH KITS OR PRODUCTS. THEREFORE, ANY ORDER PLACED THROUGH A RESELLER/SHOP/DEALER/ON-LINE STORE IS SUBJECT TO THE SAME LEAD TIMES & AVAILABILITY THAT WE OFFER THROUGH OUR WEBSITE. IF PRODUCTS ARE OUT OF STOCK ON OUR WEBSITE, THEY ARE NOT AVAILABLE ELSEWHERE.

If you purchased your kit direct through Speedtech:

ETA timeline starts from the date your order is placed and you receive your order confirmation email. Refer to the ETA timeline on our website/the product you purchased, or you can email us to check the status. Once the product has shipped, tracking is sent via the order fulfillment generated email.

If you purchased your kit through a reseller/shop/dealer or other on-line store:

CONTACT YOUR DEALER. ETA timeline does not start until the date we receive the order from the dealer. To check your order status, you need to contact the reseller/shop/dealer or on-line store that you purchased your kit through. We will only provide order information to the individual whom placed and paid for the order. Once the product has shipped, tracking is sent via the order fulfillment generated email, to the recipient whom placed the order through us.

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 and Top Mount kits)
* Bottom Mount Kit RH motor mount (differs between AWD and RWD)
* Oil feed line/fittings and oil drain block (Bottom Mount and Top Mount kits)

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 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 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. 

As with any top mount kit, clearances are tight. Clearance and fitment is verified for turbos that we sell a kit for. For any turbo not on our list; fitment is not verified. Also note that the bigger compressor housings of the BorgWarner S3XX series turbos have reduced clearance to the hood (around 3mm). With variability of motor mount isolator thickness, age, and other tolerances, fitment can be tight.

No, you need a wastegate in order to regulate the exhaust flow through the turbo to control the boost. If you purchase a kit without a wastegate from us, you will need to source your own wastegate.

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

Can I buy a kit without a turbo? Yes, we offer N54, N55, S55 & B58 No Turbo kits for sale. See our store for further details. 

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.

Can I buy just a manifold? No, at this time we are not able to sell our manifolds separately. Due to the timeline of manifold production, all manifolds (top mount and bottom mount) are used to fulfill kits. 

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. 

PSR - One of the best lower cost turbos as far as reliability and quality. T4 open, ball bearing turbos or T4 divided, ball bearing/water cooling turbo options available.

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 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.

Performance will be the same between the two kits as both are twin scroll short runners for quick spool. It really comes down to where you prefer the turbo; do you like the sleeper look, or up front when you open the hood? The top mount kit is often preferred for serviceability, especially if you swap turbos often.

You can see at the link below all the work we did during development of the kit, including making sure O2's have the best chance at a long life:

FITMENT FAQs

Yes, we designed our N54 Top & Bottom Mount kits to work with RWD and AWD. 

No, we do not have any N54 or N55 kits verified for RHD, only LHD.

We've had RHD customers install our N54 top mount kit, but they had to make a custom set of down pipes to get around the steering shaft.

No, we have not done any fitment on E60 chassis cars. Right now we have fitment for E8x, E9.

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.

Yes, the 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 135i/E82 chassis. 

Yes, the N55 Precision, PSR 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, PSR or Precision. Options for turbos for the E-Chassis xdrive are: BorgWarner, Precision, PSR, or Garrett.

PRICING & PAYMENT OPTIONS

There are many options to choose from for turbocharger kits, for which the price fluctuates.

SHIPPING & LEAD TIMES

Our kit parts have a lead time of anywhere from 2 to 6 weeks generally. Turbo lead times vary and is generally 2 to 6 weeks, but can be lengthy during manufacturer delays etc. As we do not stock turbos but rather order them per the customer specification 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.

SPEEDTECH TERMS & CONDITIONS

DOWN PAYMENT TERMS & CONDITIONS
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, payment needs to be made within 4 weeks, as all kit orders need to be finalized in a timely manner. Effective 8/26/2023: If final kit payment is not received within 4 weeks, the order will be canceled and the customer will receive a refund minus the 25% restocking fee off the full turbocharger kit purchase price that said down payment is for.

TURBOCHARGER WARRANTY
