Stage 2 Turbo Upgrade (BK2 2.0T)
Core exchange available – requires core deposit.
Average turn around time is 4-6 weeks
(depending on availability of cores it could be longer).
The stock turbo is disassembled and the compressor housing is ported to fit a larger billet 22T compressor wheel. This upgrade offers more CFM at the same boost levels (more air without increasing boost). For the stage 2, we get rid of the 11 blade turbine and upgrade it to a 9 blade HL turbine which will improve top end power.
Direct bolt-in replacement, does not require a new manifold.
Gains from 20-40hp depending on your setup and tune.
Which Compressor Wheel?
Note: We are now only offering the 6+6 configuration.
The configuration you choose will be based on your desires goals and needs. The following is a basic summation of the two options offered:
The 6+6 billet wheel has 6 pairs of blades, each pair has a long blade and a short blade. This wheel tends to offer more top end power, but will spool slower. It will do better if you’re looking to run higher boost levels, but your mid-range may suffer. This wheel will be noisier than the 11 blade, offering more of the turbo whistle and is a larger/better version of the OEM wheel.
The 11 blade will offer improvement over more of the power band and offers a smoother boost curve. This wheel tends to spool faster and will offer better mid-range. It will still offer top-end gains, but may not do so well with higher boost levels. This is the best option for daily drivers who want more power.
