Hey mate, I’d say to change your glow plugs if you’re having issues on cold startups/sometimes a bit of white smoke on a cold start. If the motor is cranking and cranking, but not kicking over, a good place to start of glow plugs. It’s a quick job, replace with a good set of plugs and you’ll be right! The intercooler is great for the aftermarket turbo. A front mount will see more airflow, however a top mount still does the job more than okay. Either way, both are great options. Just depends on the build you’re going for. Hope this helps, and thanks for the support!
