Our VT-VZ V8 Stage-5 upgrade starts with a baseline dyno run on our 4WD dynamometer to ensure your vehicle is in top condition and to establish a benchmark for post-upgrade performance.
Dyno Tuning: Optimized for 98 octane fuel, we enhance power, torque, and fuel economy. Afterward, we test your vehicle on the road, making final adjustments to optimize performance and drivability.
Our cam package utilises the latest technology and engineering advancements to enhance your vehicle's performance and reliability. Our product list includes a selection of high-performance camshafts, dual valve springs, Roll Master timing chain kits, and genuine GM components. Our cam package is the product of years of product knowledge and experience and offers peak performance outcomes for great value.
Cam selection should be based on your driving expectations and goals. Our experts are here to help you choose the right camshaft for your needs.
All LS1 engines benefit significantly from precise CNC cylinder head porting. We exclusively use Higgins Race Heads from Dandenong, Victoria, for our cylinder head porting needs. This process enhances intake and exhaust flow and includes decking the heads flat to increase the compression ratio. The heads are thoroughly reconditioned and fitted with high-performance dual valve springs.
After porting, the heads are reassembled onto your engine with new GM head gaskets and GM head bolts, ensuring a secure and reliable fit. Experience improved performance and efficiency with our expertly ported cylinder heads.
Experience the ultimate upgrade for your VT-VZ V8 with our Stage-5 package.
