NZ Performance Car - - Demon Energy D1NZ -

An­other car to de­but at round two of the Na­tional Cham­pi­onship at Man­feild Cir­cuit Chris Amon was Arthur Lee’s much-an­tic­i­pated RB28DET-pow­ered S15 af­ter its two-year build. We have fol­lowed this car’s build progress for some time as it took shape at DKM Fab­ri­ca­tion, and the fin­ished prod­uct cer­tainly doesn’t dis­ap­point. The parts list for this car would fill eight pages of this mag­a­zine if we went into ex­treme de­tail, but we will leave that for the main fea­ture in a few is­sues’ time. Still, we must draw at­ten­tion to the fit and fin­ish DKM achieved — the de­tail is amaz­ing.

Arthur, who splits his time be­tween New Zealand and China, started the project when he ap­proached DKM with the idea of build­ing a street car that was also ca­pa­ble of com­pet­ing. But as the build pro­gressed, so his knowl­edge of the ex­treme and of­ten unique re­quire­ments of build­ing a com­pet­i­tive yet re­li­able drifter in­creased. The re­sult was the S15 you see here.

The pow­er­house at the cen­tre of it all is a built RB26DET with an HKS 2800cc stro­ker kit and a Tomei head with HKS cams. The boost side of the equa­tion is han­dled by a Gar­rett GTX82R turbo with a Sinco man­i­fold and stain­less ex­haust. The in­take man­i­fold is a Hyper­tune unit, with large sin­gle throt­tle body.

The elec­tron­ics pack­age is sec­ond to none, with a full Mil-Spec loom, MoTeC PDM, MoTeC C187 dash, and MoTeC ECU. There are full data log­ging ca­pa­bil­i­ties and flat shifting for the Sam­sonas six-speed se­quen­tial, the first of its kind in D1NZ.

The RB pro­duces around 597kW ( 800hp) on pump gas, cho­sen as Arthur prefers to keep the car on a main­te­nance-free fuel given how much time he spends out of the coun­try.

The driv­e­line is as bul­let­proof as the engine it backs, with an HKS triple-plate clutch, along with a car­bon-fi­bre drive­shaft, Win­ters 267mm Quick Change diff, and axles from The Drive­shaft Shop in the USA. The rear sub­frame is a Sikky item, while up front it’s a mix of TDP and Parts Shop Max items.

Arthur is no stranger to drifting, hav­ing com­peted in China, but he plans to run the S15 here in D1NZ for a sea­son or two be­fore ship­ping it home.

The car showed huge po­ten­tial on its first out­ing, although he was tak­ing it easy to feel out the chas­sis. Ex­pect this S15 to be a real con­tender once both chas­sis and driver are di­alled.
