Click above for high-res gallery of the 2008 Chevy HHR SS

The Pontiac Solstice GXP, Saturn Sky Redline, and Chevrolet HHR SS are plenty of fun with 260 horsepower underfoot, and we can only imagine that the joy quotient increases as power improves. General Motors' performance division knows as much, and it's now offering an LNF Turbo Upgrade kit to kick its 2.0L turbo direct injection engine into gear. The kit consists of a new engine calibration and MAP sensors that will push your turbo four to 290 horsepower and up to 340 lb-ft of torque with the six-speed manual transmission (315 - 325 lb-ft with a slush box). The new factory turbo kit also keeps the precious warranty intact, which is a huge bonus over other aftermarket setups.

The LNF Turbo Upgrade also gives the GXP, Redline and SS the same "no-lift shift" functionality as the Cobalt SS Turbo, which enables you to shift without taking your foot off the accelerator. The kit also bumps the redline by 200 to 6500, but the hulkified 2.0L engine will now demand premium fuel to deliver its increased power delivery. The General is also working on a similar upgrade kit for the Cobalt SS, and it should arrive at your local Chevy dealer during Q1 2009. The LNF turbo kit delivers some added pop to three already fun vehicles, and it can be purchased at a GM dealer for $650. Is it worth the extra coin? It's up to you, but we're guessing it couldn't hurt. You can check out assembly instructions for the LNF Turbo Upgrade kit here.

      "The kit consists of a new engine calibration and MAP sensors that will push your turbo four to 290 horsepower and up to 340 lb-ft of torque with the six-speed manual transmission (315 - 325 lb-ft with a slush box)."

      I'm pretty sure every car offering the 2.0L LNF uses a 5-speed manual. The HHR SS also offers a detuned version with the 4-speed auto, and the Solstice and Sky offer an optional 5-speed automatic without reducing power. Currently, there aren't any LNF 6-speeds, manual or otherwise.

      Cool upgrade though. This is basically on par with the EVO powertrain now, but without an AWD chassis to cradle it.

      For you power/$ that is pretty impressive, add in the factory warranty backing and I'd be sold.

      Heck it cost me ~400$ to get my motor tuned on a dyno, while this won't be as individual vehicle specific, it's probably a pretty decent tune that won't blow your motor or too much fuel.

      I'm still waiting for a DI LSx series motor. Mmmmmm, come on GM.
        • 6 Years Ago
        You wont' have to wait long. The next-gen Chevy Small Block will have DI and VVT.

      I guess out the door price for the upgrade is dependent on your dealers hourly labor charge as installation is not included in the $650. Though according to GM blog it says: "The install should take only about an hour at your local dealer and is not included in the price of the kit."

      Still, VERY cool that they are offering this. As others have said, 30+hp with continued warranty coverage for $700~$800 is a killer deal. Though it does seem a little pricey as part of this "upgrade" is just an ECU firmware re-flash and most other manufacturers give you those as a courtesy when you bring your vehicle in for maintenance.

      I'm slightly impressed... Not much power added, but interesting none the less.
        • 6 Years Ago
        No kidding. That's a pretty spectacular value - you'd be hard-pressed to get those results out of a couple grand's worth of plumbing upgrades, and this retains the warranty, no less.

        Not much power? Tell me sir, does $650 get you 30HP / 80TQ out of your MX-5 or Civic Si with full warranty?

        Please enlighten me.

      Now that's what I'm talking about!

      A Solstice GXP Coupe with the chip would likely run with Challenger R/Ts and Mustang GTs but handle much better. Totally different cars, but it's woth mentioning.

      If only the Redline and GXP models weren't 32-33K ... not bad compared to a Cayman they're trying to run with yes, but what about the 370Z that's aiming at the same buyer?

      $650!!!! Thats pretty much a no brainer upgrade. My Accessport cost me nearly $500, and thats without any kind of hardware upgrade. Tack on a Garrett GT turbo, remapped MAF, and the associated trimmings and you're looking at well over $2.5k! Granted, this factory boost is rather modest, but hey, its all under warranty so, that makes up for it.
      • 6 Years Ago
      That's insane torque from 2.0L. Holy ....
      • 6 Years Ago
      As far as $/hp is concerned, this seems like a very good value.
      • 6 Years Ago
      VW... are you listening? Make this for my GTI. NOW.

      I know you can get another 100hp out of there, being such clever Germans and all...

        VW doesn't do chip upgrades.

        your buddy probably went with one of the
        major tuning companies like Unitronic, APR, REVO, GIAC

        service managers frown when they see your car boosting to 20 psi.

        I'm not sure why everyone is excited for an OEM chip tune.
        the gains/price are about right for a good chip. I think they realized
        that the aftermarket is something that they can capitalize on.
        but I'm not sure they're prepared to back up their factory waranty
        when DV's are blowing up, trannies are burning up.... and on and on.

        My friend has a new GTI, and he just mentioned to me like monday that VW offers a factory tune that nearly doubles the power for just $1200. You might want to look into that, it sounds like a great deal.

        A chip from APR will bump you up to about 245HP(from 200) and runs about $600. You wont get much more power than that since VW uses a fairly small turbo on the 2.0T. You will have the warranty issue to worry about though, but chip tuning is not anything new.

        http://goapr.com/VW/products/ecu_upgrade_mkvgti.html

        They also sell a Stage III kit which upgrades the turbo and virtually everything else connected to it. It will get you around 380HP, but is significantly more expensive, running into the many thousands of dollars.

        No they don't. Your friend is full of beans.
      • 6 Years Ago
      Yea $650..they didn't say if that includes installation. You do know how much dealerships charge per hour of service, don't you?
      • 6 Years Ago
      Does the price include installation? With my lack of electro-mechanical interaction I would be capable of an incorrect installation leading to radio reception powerful enough to receive stations from Argentina and Monrovia while causing the turbo to work only when the a/c is running.
      • 6 Years Ago
      I wonder if this engine would make sense in the Colorado.. maybe not.. but I do like the engine!

      BTW - VW does have some nice options with their turbo 4.. but stock (at least the 1.8) was slow..

      AWE does a nice tuning job around Philadelphia area - I have friends that brag theirs gives like 40-60hp and like 60-80 torque and the pricing is right in line with this.

      So why WOULDNT GM take advantage of this.. and as far as installation.. I'm sure you could bargain that at the sales table very nicely! It's 75% profits for the dealers for the labor (they charge like $80 an hour labor and pay their guys $12-18)

      I'm actually thinking about selling my MR2 spyder now for one of these.. with 300hp and 340torque.. thats a nice number.. Corvettes weren't too far ahead of this 3-4 years ago..and weighed like 300lbs more...
