Hey everybody,
This is my first post in the forum. I am coming from a 99 Pontiac Grand Prix with a 3.8L N/A engine which has plenty of torque and power, anyway when I'm driving my 13 cruze 1.4L turbo, it feels like it has no power below 3000 RPM after that I get all the power all at once seems like. If I didn't know better I'd say the engine was not building boost. What gives? Is this normal? I have even gone as far as leaving the stock resonator on and cutting off the muffler in the back but all that seemed to do is make it louder, didn't do much for power or torque.
The best part is I have no recollection of it at all!turbo96 OUCH!! The transmission went out on mine that's why I don't drive it anymore
The OEM plugs are ok - just make sure you've got them gapped at 0.028" and you're running 91 or higher octane. You should start to feel the turbo around 1800-2000 RPM. The turbo is spooled up by that time. It should be a smooth ramp up of power. Just remember, the turbo in the Cruze isn't designed for raw power but to assist a very tiny engine drive a 3,500 lb car with a reasonable amount of oomph.Hey Jblackburn
I wish I new that 2 wks. ago when I replaced the spark plugs in my car, it still had the OEM plugs in it with 111,115 +\- miles on them and the gap was around .035 anyway I replaced them with ACDELCO iridium plugs and set the gap around .028 if I knew that copper core plugs would have worked better I could have saved some money and got them instead.#kickingmyself
Everything I've experienced have agreed to this, I tried both BKR iridium and copper, I do coppers every 12-15k miles because I notice a rough idle and they're easy and cheap enough to do, I ran 87 octane for about a year with stock, ran very rough, large hesitation, bad gas mileage and little lower. switched to copper plugs and noticed a slight loss in hesitaion and a smoother ride, started running premium 91 octane and I get about 3-4 more miles a gallon, all hesitation gone, smooth ride, and a little more power.. it's not a racecar nor was it designed to be though.The coppers have a short lifespan, but they're cheap and perform the best IMO. Maintenance is frequent, though.
But yeah, the BKR plugs - iridium or copper - just plain perform better at low revs. The IFR stockers are in there for longevity and low maintenance, and that they do - at the expense of low-end grunt.
