A new turbo....PTE's 6870

The 6266 turbo is very comparable to the GT40 turbo as far as flow goes, however Precision does not have compressor maps available for their turbos for a fair comparison.

The 6266 turbo is very comparable to the GT40 turbo as far as flow goes, however Precision does not have compressor maps available for their turbos for a fair comparison. The 62mm Precision is rated to flow 72lbs/min. I would compare the GTX compressor maps, and not the older cast compressor wheel turbos.

These engines have a very high VE and large turbines are a must...did all the EBP testing to confirm.

Also, a GT35 turbo is too small for this engine because it only comes with a T3 turbine housing...which would be the same issue for any other smaller turbos on the marker. This means that the 6266 is the best option for this engine on the market by default, since it is the only mid size turbo available in a T4 configuration.

EDIT: I should add that these turbos would be happier and more efficient in the 15-20psi range, at 600-640WHP.
