4G63 ENGINES
Collin Willtshire's Datsun 1200 Ute

Collin ran 8.92 and 148MPH at the 2001 Jamboree
This was the first meeting the car was run at and surprised alot of people, once his gearbox problems are sorted out and he can run on methanol fuel and full boost we are sure 7's will be seen out of this car.

Rob Barac's Evo 3 Lancer

Rob ran 11.3 and this is outstanding for this street car with gearing suited for rally not drags, this is being change, so 10's should be just around the corner.

Engine specs
APC at Underwood approached us to build two engines for drag racing both 4G63 engine, one engine being a VR4 and the other an EVO.
We designed both engines to very similar specs except the VR4 was to run Methanol and the Evo to run C16.
Both heads were our race master design with stainless valves/ bronze guides/ competition valve springs / high temp exhaust inserts and race porting.
The bottom ends were built with forged pistons/ argo rods / polished and heat treated crank / deburred and painted block / modified balance shaft / and we blueprinted the crank and block to race specs.
We made vernier gears and dialed in the cams to suit the head and turbo.
The engines were then sent back to APC to fit to the vehicles and dyno tune.

The results of the above engines speak for themselves with 400HP plus.
