T400, Built 6.0 CV8 Monaro 🔥

Clancy’s Monaro came to us close to stock with one goal — turn it into a tuff cruiser. 😎

Out came the original motor and gearbox, and in went the built 6.0L + T400 conversion.

🔧 Supplied & fitted engine and gearbox
🔧 Pieced together the rest of the conversion
🔧 Swapped out the diff, axels and tailshaft for built items
🔧 Fresh fuel system, pump, injectors, filter
🔧 Added transmission cooler and fan
🔧 Factory-style shifter installation with custom wiring & modules to make the T400 conversion look and operate as factory-fitted as possible

Morpowa Auto & Dyno Centre got the tune dialed in with 310kw

While it was here, we also fixed the sunroof and Clancy opted for a set of 20" VF2 GTS Style wheels, finishing the look perfectly. 🔥

From a near-stock CV8 to a tough T400 cruiser — exactly how a Monaro should be. 🇦🇺

Manual VE HSV Tourer 🔥

Matt dropped his wagon off with one request:

“Needs to be choppy AF.” 😈

Out came the motor, and in went the Texas Speed Bald Eagle Cam Kit, along with all the supporting upgrades you want and need:

🔧 Trunnions
🔧 Upgraded oil pump
🔧 Cam bearings
🔧 Fresh gaskets throughout
🔧 Fresh NPC clutch kit
…and plenty more.

Then Morpowa Auto & Dyno Centre worked their magic with a fresh tune, putting down 330kW with a ripper sounding idle and retaining great driving manners.

We’d previously fitted up this Tourer with those killer 22" GTSR wheels, finishing off the look perfectly.

🔥 Another VF Redline In For Rear Airbags 🔥

This VF Redline came in for a rear airbag setup, with the tank and compressor neatly hidden away in the spare wheel well.

The perfect finishing touch to complement the 20" Rapier wheels the owner previously purchased from us. 👌🔥

Kym's LSA Clubby is back in for a bit more power! 🔥

This time we fitted a big blower camshaft along with a few other upgrades before sending it back to Morpowa Auto & Dyno Centre for tuning.
The result? A solid 460rwkw before the factory fuel pump reached its limit. Next on the list is a complete fuel system upgrade to see its full potential.

If you haven't seen this beast before, we've already completed a long list of upgrades including:
• T400 conversion with transbrake, GJ tailshaft and Kazz Diff
• Harrop upgraded supercharger lid, new lines and custom heat exchanger tank (forgot to get new pics)
• Full custom black and yellow interior retrim featuring VF HSV front seat foam upgrades, matching rear seats, door inserts, console lid, steering wheel, handbrake and T400 boot
• Sound system overhaul including front speaker repairs, sound deadening, subwoofer and amplifier installation

The crew at Playup performance also transformed the interior by replacing all the cream roof lining and pillar trims, tying everything together perfectly with the custom interior.

The result is one seriously tough street car that looks just as good as it performs.

VX HSV Senator in for a Manual Conversion 👌

While it was here, the owner spotted a set of Custom Forged 19" SVs — and we reckon they suit it to a tee 🔥

A couple years back we also did the trim, and it’s still holding up great. You don’t always have to go full custom to stand out and look the part!
