Yatala Head WorX

VIDEO: 320+ HP Datsun 1200 Dyno Run Yatala Headworx

same engine - is this the highest HP A12 ever?

A12 at QDPC

This video was posted before (10 years ago) but it was proclaimed false (video says A12, but discussion said it was 1600cc+ A15)

'676 IJP' Queenslandqpdc cruise

And a discussion in 2007when it was making "only" 240hp @ 18psi. Although the video showed 205.3hp

It was built by Tappet's mate

datsun 1200 on dyno



stock A12 bottom with some really schmick bolt-ons:
* small amount of headwork: custom-made oversize valves & port work
* custom plenum
* custom exhaust manifold
* T28 ball-bearing turbo from Nissan S15
* 440cc injectors
* Microtec ECU
* 3.5" stainless exhaust with screamer (lakes pipe?)
* BP Ultimate gasoline (99 RON octane with no-ethanol, equivalent to 93 USA octane)
* Bosch coilpacks
* stock sedan diff (Borg-Warner localized diff?)
* stock 60-series gearbox (A14/A15 gearbox)
* stock A12 head gasket failed shortly thereafter

With a planned change to:
* A14 engine
* forged pistons
* in excess of 20psi

So I guess that first video proves it's real. The made the 200+hp and then rebuilt the engine to make 300+hp. And possibly cheaper than a late model engine swap.

what are the rims off

hey shane, I count 16 holes per wheel -- so likely they are R31 16-hole pursuits
