Autometer airfuel ratio guage

[blitz27t]

Is the Autometer AFR guage worth buying, and would a 300zx tt fuel pump work and fit a 240sx (SR20DET)?

ya both are great. i would go with a walboro instead because it is cheaper.

The AFR is good to know if you are in danger of risking your motor from running lean. it is not exact but gives a rough estimate. an EGT gauge is great also but is surely does cost a lot more.
