Hello !

I have a nissan 200sx s13 with ca18det engine, and the turbo doesnt charge...

I am totally new to cars in general, this s13 is my first car.

How do i troubleshoot it ?

Thanks a ton !!!

1st Remove the hose from airbox-to-turbo
make sure the turbo is actually spinning freely.... you can check using your fingers/ motor OFF obviously
I've come accross more than a few dead stock T25s. Turbo oil feed line clogs up with crud

Definitely won't recommend a 200sx as a "first" car. They're old and a pain to work on
Better be mentally & physically (or financially) tough to take one on. Rewarding if/once you get past that tho
