Any input,both good and bad is greatly appreciated.
Btw the block is a d16a6,head is a d16z6,intake is a edlebrock perfomance x,all pushed and powered by a .42/.37 trim a/r turbo and drag manifold.
T3? T4? TD04? T58?
Giving an A/R for a turbo is a joke. Trim is a solid #. 50 trim, 57 trim....it's derived from a difference in inducer/exducer size. The A/R is an indication of the airflow path around the wheel. These are all factors that contribute to the performance, but don't tell what the turbo is.
