David’s R32 Gtr all finished up! Look at that engine bay before and after! Came out unreal. We love giving engine bays our touch and making the owners proud to pop their bonnets at car shows!

Car came to us with a pretty basic twin turbo setup, some of the things we completed include:
- Install Full HKS Turbo kit (Turbo, manifold, lines, downpipe and wastegate)
- Supply and Fit Hi Octane Racing baffled sump kit
- Get rocker covers painted Candy Red
-Installed new Turbosmart fuel reg and tidy fuel lines
- New catch can lines and powder coat some parts
- Plus a bunch more
CHEQUEREDTUNING ran it up to a nice 450kw on E85 with flex fuel. Maxing out the single fuel pump and oem fuel lines as expected, but reaching the customers goals, not to mention the insane sounds this car now makes, videos to come!

Don’t forget to shoot us a message or give us a call to get your GTR up to scratch! Limited space before the end of the year

Another R35 GT-R through the workshop! 🔥

This one came in for a few tasteful upgrades:
• Custom mid pipe
• GFB BOVs
• ECUTek flex fuel kit
• New coolant bottle

The R35 GT-R is one of our favourite platforms to work on. With the right combination of parts and tuning, they’re capable of making incredible power while still being an awesome street car.

If you’re thinking about modifying your R35 GT-R, send us a DM—we’d love to help bring your build to life. 👊

Awesome little rx2 with series 5 FC running gear. We did full custom stainless exhaust with oval section under gearbox cross member and 2x custom SP Mufflers . Also wired up the car with Haltech terminated harness and her fired to life. Been off the road 18 years, cool to see customers dreams come to life, video of the amazing noises this thing makes coming soon!

PS: Owner will be heat wrapping hot side and buttoning up a few things before dyno time!
