NZ Performance Car - - Con­struc­tion -

Pour­ing buck­et­loads of money straight into an en­gine bay is a good way to get that huge power fig­ure on the dyno; how­ever, piec­ing to­gether a us­able and re­li­able pack­age is a whole new ball park — es­pe­cially when you want to go time-at­tack rac­ing, where aero is king just as much as power is.

Si­mon Shier­law knows this first hand and has gone to great lengths to per­fect the aero pack­age on his soon-to-be RB25DET-pow­ered R32 coupe. Learn­ing as he goes and with as­sis­tance from Kyle Forster of JKF Aero in Aus­tralia, Si­mon has mod­i­fied a Do Luck front bar to form his own de­sign, along with a cus­tom-made wide­body. The rear guards are mod­i­fied R34 units with the rear sec­tion open to al­low for air­flow, while the fronts are 50mm wider cut down. The rear wing was con­structed by The Lab Lim­ited in Hamil­ton, and mea­sures in at 1800x340mm. With a rear al­loy dif­fuser to top it off, all pieced to­gether, it’s a very slick pack­age thus far. Mean­while, the heart is be­ing re­vived via a front­fac­ing plenum, 900cc fuel in­jec­tors, Spit­fire coils, a Holset turbo, a front-mount in­ter­cooler, and a se­ries of other good­ies in the boot — in­clud­ing a cus­tom fuel cell, surge tank, and Bosch 044 pump combo.

Si­mon in­tends to use the car in street sprints, hill climbs, cir­cuit rac­ing, and NZ Su­per­lap. Ba­si­cally, any­thing where he can pedal the car to its lim­its with­out get­ting into trou­ble from Johnny Law. It’ll be in­ter­est­ing to see how the rest of the build plays out.
