DESCRIPTION

Lightweight flywheel for quicker, effortless revs that improve throttle response and free up lost horsepower. Tested and approved by the engineering team at Turner Motorsport. Tested in early, late, ETA and IS model E30s for confirmed fitment.

Introducing the Turner Motorsport M20 Flywheel: an ingenious blend of lightweight design, rich features, and remarkable strength! Crafted from 4140 HT Steel, this flywheel is precision-machined from a solid piece, ensuring unmatched durability. By strategically trimming excess weight from its original design, they achieved a significant reduction in weight, giving new life to your M20 engine. With upgraded efficiency, your M20 can now swiftly spin to high RPMs, unleashing the full power of this absolute unit of an engine. The Turner flywheel features a ring gear profile compatible with all starters, alongside a reference tab tailored for early cars equipped with bellhousing-mounted sensor crank position detection.

Do you have an early model transmission with the crank sensors on the bellhousing? Maybe you have a late 325is with the crank sensor on the front of the engine, or maybe you have a 1988 super ETA. No matter which E30 model you have, this flywheel is the perfect choice for you.

During the engineering process, the team at Turner encountered the full spectrum of M20 and flywheel combinations. Early cars with bellhousing crank sensors, late cars with front mounting crank sensors, and even a super ETA. On this adventure, they found both early and late single-mass flywheels and even the dual mass that was thought to be just a myth at this point. At first, they were hesitant that we could make one flywheel to fit them all but with the persistence of the engineering team (fleet of E30 enthusiasts), we can proudly say this M20 flywheel does in fact fit all engine and transmission applications you can think of.

Features and benefits:

  • Fits early and late models with the M20
  • Fits shallow and deep bellhousing transmissions
  • Ring gear suited for both starters (P# 12411726504 + 12411361874)
  • Heavier than other lightweight flywheels, and lighter than OEM, it's like the Goldie Locks of flywheels - it's just right
  • Reference pin for bellhousing crank sensor
  • Strong Single-Piece 4140 HT Steel construction
  • Designed to be used with factory and OE clutches

Weight Comparisons:

  • ​Factory single mass flywheel EARLY (11221705046) - 23.69 lbs.
  • Factory single mass flywheel LATE (11221706573) - 18.74 lbs.
  • Dual mass flywheel (21211225979) - 27.56 lbs.
  • Turner flywheel - 14 lbs.

What you need:

  • Short bellhousing transmissions (I/IS) - Throw-out bearing P# 21517521471 (325)
  • Tall bellhousing transmission (ETA) - Throw-out bearing P# 21511204525 (323)

Please read before ordering. Eurosport Performance does not carry live inventory on this site. Most products are ordered for you directly from the manufacturer or our suppliers, and we follow their lead times. Placing an order confirms you have read and accepted the availability terms below.

Ships within 24 to 48 hours
Products marked in stock are on our shelves in Montreal and leave within one to two business days.
Ordered for you
Most orders ship in 5 to 7 business days
Everything else is ordered from the manufacturer or supplier when you order. Delays can occur; if they do, we contact you.
Supplier lead times apply
If a product is not listed as in stock here and is on backorder at the manufacturer, it will most likely be on backorder for us too. We will tell you as soon as we know.
We keep you informed
You receive a confirmation when the order is placed, a notice if a delay comes up, and tracking the moment it ships.
Frequently asked questions
Is this product in stock right now?

Only products explicitly marked in stock are on our shelves. For everything else, the fastest way to know the current lead time is to ask us before you order; we check with the supplier and reply with a date.

Why does my order say "confirmed" but has not shipped?

Confirmed means we have placed the order with the manufacturer or supplier on your behalf. Shipping follows once the part reaches us or ships directly to you, usually within 5 to 7 business days for products that are available at the source.

What happens if the part is on backorder?

We tell you as soon as the supplier confirms it, with the expected date when they give one. You can keep the order open, switch to an alternative we suggest, or cancel for a full refund before the part ships.

Can I cancel if it is taking too long?

Yes. Any order that has not shipped can be cancelled by contacting us, and the refund goes back to your original payment method. Please contact us rather than opening a dispute with your bank: a cancellation takes us minutes, a chargeback takes weeks and freezes the refund in the meantime.

Do you ship directly from the manufacturer?

Sometimes. Larger or special-order items can ship to you directly from the supplier to save days in transit. You still receive tracking from us either way.

Where do my parts ship from, and are there duties?

Orders ship from Montreal or directly from our suppliers. For Canadian addresses the price you pay is the price, with no import or duty fees added on delivery. See our shipping policy for details.

How will I know when it ships?

You get an email with the tracking number the moment the label is created, and you can follow the order in your account on the site or in the SPECD app.

Want a lead time before you order? Email us or use the contact page with the product name and your vehicle, and we will confirm availability with the supplier.

WARRANTY

Products are warrantied by their manufacturer. Eurosport Performance is an authorized reseller: every part we sell is covered by the manufacturer's own warranty, with its own terms and duration. Claims go through us, so you deal with Eurosport Performance rather than a form on the brand's site, but whether a claim is accepted is the manufacturer's decision.

Manufacturer terms apply
Duration and coverage are set by the brand and differ from one to the next: some cover one year, some a lifetime, some only the original purchaser. The brand's warranty page is the reference; ask us if you cannot find it.
We file the claim for you
Contact us with your order number, photos and a description of the issue. We open the claim with the manufacturer, follow it up, and arrange the repair, replacement or credit they approve. The manufacturer decides whether the claim is accepted.
Fitment guarantee: North America only
We guarantee fitment for vehicles sold in the North American market. Vehicles from other markets are out of scope; specifications differ, and it is the customer's responsibility to confirm compatibility before ordering.
No warranty on tuning files
ECU and TCU tunes and other software files are sold without warranty and are not returnable once delivered or flashed. Tuning can affect your vehicle's factory warranty; please read the brand's terms before purchasing.
Proof of purchase
Your Eurosport Performance order is the proof of purchase every manufacturer asks for. Keep the order confirmation; it is also in your account on the site and in the SPECD app.
What is usually not covered
Damage from improper installation, modification, abuse, racing or an incorrect application for the vehicle, and normal wear items such as pads, clutch discs and filters. Shipping and labour are covered only when the manufacturer's terms say so.
Frequently asked questions
How long is the warranty on this product?

It is the manufacturer's warranty for that product. Where the brand publishes it, we note it in the description; otherwise contact us before ordering and we will confirm the exact terms with them.

A part failed. What do I do?

Stop using it if it is a safety-related part, then contact us with your order number, clear photos, and when and how the issue appeared. Do not return anything until we confirm the claim; manufacturers often require an inspection or an authorization number first.

Who decides if my claim is accepted?

The manufacturer. We prepare and submit the claim, provide the proof of purchase and push for a fair outcome, but acceptance, replacement or credit is their call under their terms. We pass their decision on to you as soon as we have it.

How long does a claim take?

It depends on the manufacturer. Simple cases are approved in days; claims that need the part inspected can take a few weeks. We keep you updated at each step and push when it drags.

Is there a warranty on ECU or TCU tunes?

No. Tuning files are software; once delivered or flashed they cannot be returned, and they carry no warranty from Eurosport Performance or, in most cases, from the tuner. Support for the tune itself (revisions, flashing questions) comes from the tuning brand under its own terms.

My car is from outside North America. Is fitment guaranteed?

No. Our fitment guarantee covers vehicles sold in the North American market only. European, Japanese and other market vehicles can differ in engines, electronics and dimensions, and a part listed for the North American model is not guaranteed to fit. If you order for one of these vehicles, confirming compatibility is your responsibility, and fitment issues on such vehicles are not covered by returns or warranty.

Is installation covered?

Labour is not covered unless the manufacturer's terms specifically include it. Having the part installed by a qualified shop protects your claim: improper installation is the most common reason a manufacturer declines.

Is a warranty issue the same as a return?

No. Returns cover unused parts you no longer want, under our refund policy. Warranty covers a part that fails in use, under the manufacturer's terms. If you are unsure which applies, contact us and we will point you to the right one; please do not open a bank dispute, as it pauses both processes.

Questions about coverage before you buy? Email us with the product and your vehicle and we will confirm the manufacturer's terms.
