What is wrong with the stock turbo?
The factory 3.0L LZ0 Turbo at 42.3 mm will supply enough air to deliver a MAX of +50HP over stock power to the motor - safely but this is the very end of . We have found during testing that anything more than that is pushing the turbo off the compressor map and only adding unnecessary heat to the system.The factory turbo will generate 33 lbm/min of corrected airflow at max output which will generate right at 290RWHP.
Enter VSE LZ0 47mm Sgt2 3.0L modified turbo
Goal 1 of building a modified LZ0 turbo was efficiency. Efficiency creates an increase in fuel economy. We utilized a very small internal core (11mm vs 13mm) This eliminates drag across the volute of the turbo and keeps the turbo away from surge under load.
Goal 2 of building a modified LZ0 turbo was a reduction in rotating weight. We reduced 6 grams of rotating mass while making the turbo larger by nearly 5mm. Less weight = quicker spooling and provides an increase in economy and a more responsive turbo.
Goal 3 What everyone came for - Power!! Our target was an increase in power of 50HP over the factory turbo max to yield a total power increase on the LZ0 of 100HP over stock using a stock intake and heat ex-changer - and we did just that. We have tested the factory LZ0 bottom end to well over +100 RWHP nearing the limit of the fuel system and the rotating assembly and head gasket/bolt design can easily withstand the slightly higher cylinder pressure that comes with it.
VSE 3.0L LZ0 Stg2 Turbo Features
- 47mm by 63mm Compressor (Stock is 42.5 by 66mm)
- 57 grams (Stock is 63 grams)
- Designed for higher RPM operation due to a more robust material strength chosen than OEM
- Modified exhaust/turbine components
- Optional cerakoted exhaust housing (reduces external compressor temperates by 200F and allows removal of the heat shield) !! This is highly recommended !!
- Compressor wheel features slow speed balancing procedures for minimal radial corrections
- Turbine / rotating assembly features a high speed balancing procedure (+100K rpm) to ensure survival under the most extreme conditions
- 10.6mm Modified Exhaust vane cage (Stock is 7.6mm) This is the choke point of the LZ0 turbocharger by not allowing exhaust to escape into the turbine to drive it.
- 52 by 48mm 9 blade 9.8mm nozzle exhaust turbine wheel (Stock is a 50 by 43mm 11 blade wheel 6.8mm nozzle) this allows quicker spool times, low drive pressure and an amazing 9 blade sound
VSE Tuned Already?
If your LM2/LZ0 has already been tuned by VSE, make sure to input your tuning order number or the VIN within the turbo order. We do not charge modifications for our own turbos.
Actuator
All years LM2 and LZ0 you will swap the actuator off your old turbo and install it on the new turbo. No VGT relearn should be required if the process is followed on turbo swap correctly.
