SR20DET Power Up

Dante brought us his ’91 240SX for some upgrades and tuning.  We upgraded the fuel injectors to Nismo 740s, and swapped in a Z32 MAF.  The SR engine has the stock exhaust manifold and turbo still attached to it.  A Blitz sbc-iD Spec-R controls the boost.  Stock down pipe and full 2.5″ exhaust along with a Greddy intake manifold.

91 octane & a peak of 14 psi.

  1. At 14 psi with the stock turbo, are the 740’s really even needed? All the data I have read up on is that the stock 370’s are sufficient for that boost level.

  2. No, but there are brighter futures ahead, with more power in them.
