TTE 600 and TTE 680 N54 Core Return Deposit

Reserve your TheTurboEngineers 600 or 680 upgrade the easy way with our returnable core charge. This listing is the deposit only to secure an exchange set for your N54 performance turbocharger upgrade. No turbochargers or hardware are included with this product.

If your originals are still fitted to the car, simply purchase this £250 ex VAT returnable charge. We will allocate a spare set for the swap, subject to availability. Send your undamaged factory units back after installation and, once they pass inspection, your deposit is refunded.

Why choose this exchange deposit

• Minimal downtime so you keep the vehicle on the road while preparing your upgrade.
• Fast turnaround with an allocated exchange set for the N54 platform.
• Straightforward core return process and a clear, returnable surcharge.
• Proven with our own builds and trusted by MJ Modifications customers for consistent, repeatable results.

How it works

1. Purchase this TTE N54 core return deposit if your stock units are still on the engine.
