This 4G63T-powered GSR nearly didn’t make it into the show, as it was the wrong colour for this year’s UMF club theme, so owner Nigel hopped on the gun and gave it a few licks to suit. That clearly represents a hearty effort, but if you take a gander into the engine bay, you’ll just be blown away. Off the bat, you’ll notice the rather large HRC40 hiding directly behind the grille, held in place by a BNR Engineering manifold that includes a TiAL 44mm V-band MVR wastegate. To support such madness, the bottom houses Wossner pistons and Molnar rods, attached to a seven-bolt crank and fitted with ACL Race Series bearings. Up top, the heads were cleaned out and now house Hartley Engines and Motorsport camshafts that operate the BC stainless valves and springs — air is fed in by an 80-millimetre throttle body, whereas the exhaust is ridded by a 3.5-inch mild-steel system through to an Adrenalin R muffler. A Walbro lift pump–and–twin Bosch 044 combo feeds fresh E85 into a HKS fuel rail that contains Bosch 1680cc injectors, while a Link G4 Plug and Play monitors the whole ordeal. Ignition remains factory at this stage, with upgraded Eagle leads, although Nigel intends on addressing it at a later stage. A Fenix Performance half-size radiator and intercooler tuck away nicely, with an aftermarket oil cooler hidden among it all, too. Wanting to keep everything looking relatively tidy, the bay has been semide-loomed. The entire package produces a hefty 403kW at all four.
