Common questions
Quotes & pricing
How much is a drive-in, drive-out M57 conversion?
Roughly $35,000–$65,000 for an ASLmods-supplied package, depending on engine, gearbox and any performance or refresh options. For an itemised quote, send us your name, email, phone number and vehicle rego (plus the donor car's details if you have one). See our Workshop & fitting page for what's included.
What do you need from me for a quote?
Your name, email, phone number and vehicle rego, your current engine and gearbox, and what you're after: M57N or M57N2; ZF 6HP26X, 6HP28X or 8HP; auto or manual; stock or performance. Our quotes are catalogued, so don't worry if you can't answer every line.
Do conversion kits include the engine and gearbox?
No. Kits don't include the motor or gearbox, but we can quote a complete supply package, including a donor car.
Does the quote include engineering?
No. We build to the correct standard, but engineering inspects the whole vehicle, so we don't quote it. We can manage the engineering process for you if we inspect the whole car first.
Which engines do you convert?
We specialise in M57 (M57N and M57N2) and 1VD conversions with ZF 6-speed and 8HP gearboxes, mainly into GU/GQ Patrols, 80/105 Series LandCruisers and Defenders. We don't do N57, HD/1HZ, LS or OM606 swaps in-house.
Which engine should I use — M57, M57N or M57N2?
All three are 3.0L BMW straight-six turbo-diesels. The M57N (218 HP) and M57N2 (231 HP) are the most common conversion engines and have the widest kit support. If you're unsure, send us your vehicle and gearbox and we'll recommend the right combination.
Auto or manual?
We specialise in ZF automatic conversions, but manual conversions are available too.
Do you fit conversions and parts in your workshop?
Yes. We do complete drive-in, drive-out conversions from our Myaree, WA workshop, and we can fit any part we sell, including suspension, wheels and tyres. See our Workshop & fitting page for services and pricing, or contact us to book your vehicle in.
Can I pay by credit card or AMEX?
Yes, over the phone. A 1.5% card surcharge applies. Bank transfer has no fee.
Do you offer trade pricing?
Yes, on most supplied parts. Send us the vehicle VIN or rego and the part you need.
Orders, shipping & pickup
Where is my order? When will I get tracking?
Tracking is emailed when your order ships. Some items ship direct from our supplier, and their tracking comes from them. If you haven't received it within 2 business days of your dispatch notice, text us on 0477 313 106 with your order number and we'll send it.
Is it in stock, and how long will it take?
Stocked parts ship promptly. Popular items can go on backorder, and the current lead time is shown on each product page under the Add to cart button. Fabricated components are made to order in our Myaree workshop and typically take around 3 weeks. Custom wiring looms are built in-house to suit each vehicle and take 8 weeks, starting once we've received your harness and ECU. For an up-to-date ETA on a specific part, text us on 0477 313 106.
Do you ship interstate and overseas?
Yes. We ship Australia-wide and to the USA and elsewhere. Shipping is calculated at checkout.
Are your parts genuine?
Our BMW parts are genuine, sourced direct from Europe.
Can I pick up my order or get it delivered locally?
Yes. Pick up from our workshop at 20 Thurso Rd, Myaree, Monday to Friday 8am–4pm. Choose pickup at checkout, or just come in: cash or card on pickup is fine and no online order is needed. Perth metro Quicklee delivery is also available; call 0477 313 106 for more info.
ECUs, tunes & wiring
Do you sell tuned ECUs, or do I send mine?
You normally supply your own ECU and TCU. We tune them in-house (immobiliser delete, emissions delete and performance tune in one), with a turnaround of about 3–4 days. We regularly send tuned ECUs back to customers interstate, including Melbourne and the rest of the east coast.
Can I buy the kit now and send my ECU/TCU later?
Yes. Most people buy the whole kit so we can prepare everything, then send the electronics when they're ready.
Will my existing tune survive the conversion?
No. The conversion makes it a different vehicle, so it's always retuned. Our tune includes a hard cut.
Simplified loom or plug-and-play loom?
The simplified loom has a quicker turnaround but leaves more wiring for you to do. The plug-and-play loom just plugs in.
Can I delete the MAF?
Yes. It's turned off in our tunes.
Can you add EGT or paddle shift?
Yes. EGT can be displayed on a Haltech dash, and paddle shift is supported.
What do I need to cut from my donor harness?
We have a harness-removal video that walks you through it. Text us on 0477 313 106 with your donor car's model and year and we'll send you the link for the right version.
Fitment & technical
Will your kits fit my vehicle?
Each kit lists the vehicles and gearboxes it suits. We officially support Nissan Patrol GU/GQ, Toyota LandCruiser 80/105, Land Rover Defender, Jeep and Navara/Pathfinder, and many customers adapt our parts to other vehicles. Use the Engine filter in the shop to browse by engine, and ask us before ordering if you're not sure.
Which driveshafts and crossmember for a ZD30 auto to M57 / 6HP26X?
Use the manual driveshafts with the auto crossmember.
Does the Toyota HF2A transfer adapter keep high and low range?
Yes, as standard.
Are your supplied engines tested?
Yes. Every engine we supply gets a compression test, injector value and feedback test, boost performance check and leakdown test.
Is there an injector upgrade for the M57N2?
Not as such. We recommend new injectors plus an upgraded high-pressure fuel pump. We sell genuine Bosch injectors for all M57 variants.
Do you sell dump pipes for the GU bolt-in mounts?
Yes, custom-made. Ask us for a quote.
Warranty & returns
What's the warranty?
See our Product Warranty Policy for full details, including your rights under Australian Consumer Law. We can also email you our warranty T&Cs and FAQ sheet; just contact us.
My clutch failed after the conversion. What should I check?
The clutch disc is the designed weak point. The most common cause is a missing spigot bearing. Before replacing the flywheel, check dual-mass play: maximum 11° (4 teeth) rotation and 2.9 mm peripheral play.
I cancelled or returned an order. When will I get my refund?
Refunds are handled under our Returns & Refunds Policy. To check where yours is up to, text us on 0477 313 106 with your order number.
