Honda FD2 Turbo 😎

Another beautifully built Turbo conversion from RW-Developments featuring a Turbosmart 5862 Turbo, ID1050x injectors and RW Developments hardware. Tuned@EFI.

315hp Mk4 Clio RS 💪

Adey’s Clio 200T made a return to see what we could do with his new setup. Stock engine with Mk4 Megane 300 turbo and twin scroll manifold and Mk4 Megane fuel pump. Even the Megane down pipe fits with minimal alteration. 1.6 bar of boost.

Much more responsive than the laggy hybrids available for these engines.

Clio TURBO 💪

A lovely clean build using conversion components from Engine Dynamics and one of our Clio Forced Induction Modues which allows us to properly retune the factory ECU.

400hp Megane 3 RS!

We tuned Dan’s Megane a couple weeks back and were a little disappointed with the 380hp result. Power rolled off too early.

Thankfully, soon after Dan and his friend observed that the cam timing was off and so they corrected it and brought it back for round 2.

Much better, and now making over 400hp as it should.

Forged engine, 870cc injectors, G25-660 (yes, a little over kill in this case) and 1.6 bar of boost 💪

1000hp+ B-series!

Well done Matt Davison and the Mr Boost team with their Civic EF drag car for the 8.4 @ 184mph pass today at Santa Pod!

XFWD sleeved block, aluminium rods, methanol and FuelTech ECU. Check out the 3D printed manifold! Tuned@EFI.

Jonny’s Clio 172 TURBO 💪

A lovely clean build utilising an Engine Dynamics Turbo kit, our stock ECU software and forced induction module.

07/08/2026

Aaron’s 324hp Supercharged Clio!

Another interesting Renault RS that came along for tuning. This one has a built engine with Wossner pistons. PEC rods, 630cc injectors and an ECU Master plug and play ECU solution from RRR.

21/07/2026

It’s K20 TURBO time again, with another super clean, faultless conversion from RW-Developments.

Stock engine, Turbosart turbo and Haltech Elite 1500 plug-and-play ECU.

20/07/2026

480hp Kangoo VAN!

Jon’s no stranger to building interesting, powerful stuff.

This time round he brought his track-day Kangoo van to us for tuning.

The engine is a Megane RS bottom end with a Clio 3 RS cylinder head, VVT, 172 cams, G25-660 turbo, Bosch 870cc injectors controlled by an ECU Master black with Renault CAN integration.

By his own admission the handling needs ‘work’ but it’ll be a blast on the straights if nothing else 😁

Integra DC2 with some ITB action 😎💪
