13.0:1 compression D16Z6 on pump gas. The goal here is DOHC VTEC B-Series swap level performance out of a budget D16 build. We will be performing several different intake and header tests with this motor, with dyno charts for all to see.

 

The above dyno chart shows powerband comparison with a tuned B16A2 with GSR cams/J's racing CF intake/Greddy header/2.25" exhaust on the same dyno. 

 

Red line is Natural D, Green line is B16A2. Not bad, huh?

This is the trusty vitara pistoned sohc that's been in our race car for the last 2 years. 

 

Current Best Times: 10.4 @ 138mph
