Message: [QUOTE="firehunter, post: 1529034, member: 1162"] I guess I will chime in with my experience as I am a sample size of "one" who was not happy with 160/30's and much happier with my current 160/80's. I got the 30's some years ago when they were relatively new to the scene, immediately after install they smoked white/blue on cold idle when oil temps were below 60*F. I started a thread on here back in February of 2013 about the smoke with plenty of responses but no real solutions. I only ran those injectors for ~10K miles (a guess, don't remember) and at the advise of the tuner switched to the more experienced and proven 80% nozzle. Unfortunately these 160/80's still smoke under the same cold conditions but not nearly as much as the 30's. As to "hot and smokey" I have had zero issue with the 80's being either of those. The only time I can get these injectors over 1200* EGT is if I intentionally mash the throttle at relatively low RPMs (manual transmission). If I maintain reasonable RPMs matched to the load I am pulling then I rarely see over 1000* - ever. Smoke could be an issue when towing if I stepped on the throttle hard but was easy to manage by smoothly rolling into the throttle. As to "oil hungry" I have never had an issue with this and my adrenaline pump - I will let off the throttle before the injectors start to lose pressure. These injectors just keep pulling and pulling on the top end! Fast forward to just a few months ago and the addition of the KCTurbos SXE drop-in turbine wheel and smoke while towing is no longer an issue - ever. EGT's are never an issue. Unfortunately the injectors still smoke blue/white/fuel until oil temps get to 60* then smoke shuts off like a switch. Per a compression test the engine is healthy with no blow-by and very little oil consumption between changes (never have to add). I have ~90K miles on these 160/80's. FWIW [/QUOTE]
