BagSport Rear-Mounted A-Series Turbo Kit — GBC20-300, Carb, Non-Intercooled (One Only)

One kit only. Brand new, unused, and shipped direct from BagSport Fabrication in the UK.

This is a single BagSport Rear-Mounted A-Series Turbo Kit in the GBC20-300, carb, non-intercooled spec. It was the kit behind our recent raffle. The raffle paid out as a cash prize, so the kit is up for sale, well under what a new one costs to import yourself.

BagSport's 2026 rear-mount package is a true bolt-on: no cutting, no trimming, no welding. The turbo sits on the bulkhead side where the exhaust manifold always lived. If you ever take it back off, the shell is exactly as you found it.

Spec

• Turbo: Garrett GBC20-300 (journal bearing). It's the mid-range option, with room to grow into a built engine without going soggy down low.
• Fuel system: Carb (plenum chamber included)
• Intercooler: Not included. This is the non-intercooled kit.
• Output: Suitable for a standard engine on low boost, and capable of 200+ hp on a built engine and gearbox

Shipping and import duty

This kit ships directly from BagSport Fabrication in the UK, anywhere in the world. Shipping to your door is included in the price.

Import duty, taxes (such as VAT or GST) and any carrier brokerage fee are paid by you when the kit is delivered. For US buyers, duty is currently around 10-15% on UK auto parts. Even with that added, it comes in well under the cost of importing a new kit yourself.

Because it ships from the UK, this kit is final sale unless it arrives damaged or isn't as described.

Photos show BagSport's demonstration build, which is the intercooled version. The kit for sale is the non-intercooled carb kit described above.
