Just buying a LS conversion kit (used engine, gearbox and wiring loom etc) is hideously expensive compared to rebuilding the Barra and you don’t even get a “new engine” You pay probably around $3000 just for a long LS engine and then you’ve got to rebuild it into something better
Not bagging the Barra. I don't know much about it, everyone speaks well of it, but the rebuild cost is just the start. Getting it fitted in the engine bay and then mated up with a gearbox etc involves a fair amount of engineering and cost.
The Holden/Nissan RB30 is another good choice but then again needs a fair amount of engineering work to get it fitted up and running.
Or you could go the twin turbo route with the turbo version of the LFX engine in the VF. This would keep the weight distribution in line with the original car.
Other GM models includes the VF.LF3
The 3.6 L twin-turbocharged version for the 2014 Cadillac CTS and 2014 Cadillac XTS was announced at the 2013 NYAS.
The engine is rated at 420 hp (313 kW; 426 PS) of power at 5750 rpm and 430 lb⋅ft (583 N⋅m) of torque at 3500-4500 rpm (with 90% of torque being available at 2500-5500 rpm) and helps the CTS achieve 0–60 mph (0–97 km/h) time of 4.6 seconds with an 8-speed automatic transmission.
In essence, the twin-turbo 3.6L V6 is the forced-induction variant of the popular LFX V6 found in the Cadillac ATS, XTS, and SRX, among many other GM models.
Using an engine that already fits in the chassis has a fair bit of appeal to me.
Red Bull did the twin turbo V6 Sandman. Not sure which model/size engine they used.
