There was a time when fanny packs were a status symbol, a shag cut had nothing to do with the backseat of your car, bricks were considered aerodynamic and Nissan was a brand no Datsun owner had heard of.
This Open Class 1971 Datsun 1600 (510) time attack weapon is keeping the best part of those things alive, with plenty of modern upgrades. Powered by a, ahem, 'Datsun' SR20 pushing 350kW (470hp) to the wheels via E85, 25psi (1.7Bar) of boost, a BorgWarner EFR7670 and a Samsonas 6-speed sequential, this flying brick is a credit to all involved especially owner/driver John Healey of V-Sport Australia.
Electronics are handled by an EMtron Kv8 ECU, MoTeC C125 dash and PDM 15. John is getting as much value as possible from the PDM which is about at its limit powering everything in the car, including the electric steering setup, something we don't commonly see used in time attack builds.
The SR20 is a bit of an unknown, with John having had some head work done, but the bottom end left as it was purchased secondhand. A Bosch DBW throttle body to assist in rev-match downshifts to help avoid some of the issues that are well known to kill SR20s, and along with a 7,800rpm limit, so far so good!
A universal Sydney Composites aero kit has been fitted, and as you would expect of someone from V-Sport, the brake package is on point with the Datsun 510 utilising an AP Racing pedal box and 4 pot front brack calliper, Brembo 4 pot rear and pretty much the biggest discs you can squeeze under 15" wheels.
