YOUR BUILDS
JON’S KILLER DATSUN COUPE BUILD
JON’S BUSY BUILDING ONE MEAN LITTLE ’70 DATSUN
The 1970 Datsun 1200 coupe was a second-owner vehicle with just 118,000km, full service history and books. It was supposed to be a quick clean up and drive project.
Once I started stripping it back and saw how clean and original it was, the project just grew from there.
The attraction was with the vehicle being a 1970 build, and being born in 1970 myself, it was more about the sentimental nature of building a vehicle of my birth year.
Rather than go the usual route and converting to EFI and turbo, I wanted to keep the car period correct, looking at option and mods available in the period and in keeping with the heritage of the vehicle.
At the time I was looking at engine options, a crashed 1200 sedan that had competed in Classic Adelaide was on the market. The 1200 raced by Zac Caudo had been well set up and been very competitive in the outright classic competition, and the car had met its fate on a dirt rally event.
The engine is an A15 that was originally built by Road & Track here in Adelaide, and since purchasing the motor I have done further improvements:
- Full ported & flowed head with the largest valves possible to fit
- Faced to increase compression
- Yella Terra roller rockers
- Tomei head gasket
- Tomei high-comp pistons
- 79mm bore
- Sure cam custom-grind billet cam, ground to make peak power at 10,000rpm
- Knife-edge crank
- Full balanced rotating assembly
- 13.5:1 compression
- Electronic dizzy
- Twin 40mm Webers
- Lightweight fly wheel
- OS Giken clutch
- AE86 t50 gearbox
- 310 front rotors with Volvo 4-spot calipers
- R31 rear calipers and rotors
- 8-inch full spool 31 spline diff assy
- KYB shocks all round with 240Z coil over struts
- Wheels are Rota Cherry Blossom 15x9 all round
- 195/50 fronts
- 205/50 rears
- New body rubbers throughout
- Rego Sun 110
- Bodykit combination of MR2 and Te27
- Body full paint strip inside, outside and underneath
