We have a one off deal on the A20DTH Insignia development turbo used on the TP Remapping post below. £460 inc VAT gaskets, and UK delivery. Usually £625 + VAT.
The unit has been run for a few months on Tom's personal car before he went in a different direction with it, but will be overhauled with new bearings, seals etc so virtually good as new.

🚨 A20 Project: GTB1756 Tuning Results Are IN! 🚨
After months of hard work, the A20 Project is finally delivering big results – 253bhp and a jaw-dropping 573Nm of torque!
It's been a journey of trial and error, but we’ve finally cracked the code on the GTB1756 turbo setup – and trust me, this thing absolutely rips!
You haven’t heard from us in a while, but that’s because we’ve been deep in the trenches perfecting this beast. There were times I nearly threw in the towel, battling relentless overboost issues. But phase 1 is now complete, and it’s performing better than we could’ve hoped.
Key Mods:
GTB1756 turbo from Springer Adam Davidson
90mm intercooler + hardpipes
4-bar MAP sensor
2400 rail sensor
CG Motorsports Stage 3 clutch
Custom 3-inch exhaust system
Custom cold air intake
Badass Performance air intake
It’s taken over 30 custom files and countless late nights, but the payoff is real.
Special shoutout to Anthony Moreels at AM Tuned – his experience with GTB setups was a game changer, especially when it came to smoothing out the power delivery.
A big thank you to Evolution Diagnostics and Tuning for Dyno time too! Thank you Jason!!
CustomCobtuning for fitting all the modifications
Stay tuned, because this is just the beginning!
