With low-down torque and re­sponse on his mind, Cam Her­bert only saw one di­rec­tion to head in when build­ing an RB30 for his R32 — run­ning twins. “I’ve al­ways loved [Sky­line] GT-Rs, par­tic­u­larly for the twin-turbo set-up. The sound of two tur­bos, two waste­gates, and two ex­hausts is a thrill,” he said.

“When I started the build, it was just a bare RB30E block and se­ries two RB25DET head, which I wanted to make as torquey as pos­si­ble low down in the rev range, so, nat­u­rally, us­ing two small tur­bos was the way to go.”

Two and a bit years on, and Cam tells us that things have es­ca­lated be­yond those ini­tial thoughts. The pack­age now makes use of a R34 GReddy in­di­vid­ual-throt­tle-body (ITB) sys­tem with two steel-wheeled R34 N1 Gar­rett tur­bos sit­ting atop a cus­tom twin-turbo ex­haust man­i­fold fab­ri­cated by fel­low Bridge City Col­lec­tive mem­ber Adrian Wil­liamson.

Out­side of the bay, Cam has lopped off the old tube-front, ready to be re­made by Joel Paterson, with the re­make set to repli­cate that found on the VID D1NZ Sky­lines. And, as the chas­sis is that of a ded­i­cated drift car, it cur­rently uses A32 tie rods with cut-and-shut knuck­les for added lock. But these will be re­placed by mod­i­fied J-arms in the in­terim, be­fore switch­ing out for GKTech knuck­les and cas­tor arms for some se­ri­ous lock and to keep things in D1 rules.

The cage and seat/har­ness set-up will fol­low the same route, keep­ing the door open for fu­ture com­pe­ti­tion use. When that time comes, Cam tells us that the oth­er­wise un­opened mo­tor will be re­built with forged in­ter­nals and to chase a touch more power.
