Can you run a billet block on a street build? With 1650whp what 1/4 mile time can a full trim R34 do?

With 1650whp at 55psi of boost this R34 GTR Skyline is arguably one of Australia's fastest roll racers, and even more impressively this 1600kg car will do 8-second passes while retaining the full stock trim as Av from B2R Motorsports explains.

Running a 3.4l Bullet Race Engineering 'hybrid' billet block, this 3.4L RB has all the usual suspects covered modification-wise internally including a Callies Performance Products custom crankshaft, CP-Carrillo rods and pistons, Ferrea copper bronze valve guides & more, but interestingly retains a relatively stock cylinder head. The car runs pump E85 (ethanol fuel blend) with a 9.5:1 compression ratio, and like you would expect, the Nissan CAS is in a rubbish bin somewhere with a Ross Performance Parts 36-2 trigger kit replacing it.

A Precision GEN2 Pro Mod 88 turbo handles the forced induction side of things with a plug and play Link ECU G4X R34 PnP covering engine management. Fuel injection limitations in both the current setup and with this specific ECU option will see the team move to a batch fire setup in the future, which is a common and proven solution in situations like this.

An Albins Performance Transmissions ST6, Hollinger Engineering 9" rear and ETS-Pro torque split controller handle most of the drivetrain requirements with the standard ATTESA system still handling things for the most part for now when it comes to AWD.

The car is lacking in safety features for 1/4 mile runs and will need more attention in this area in the future for this use, however, for roll racing only at the likes of Sydney Motorsport Park a safety structure/roll cage is not a requirement.
