Click above for a high-res gallery of the Hyundai Genesis Coupe's 2.0T engine

The Hyundai Genesis Coupe is already winning praise from the motoring press, and enthusiasts are itching to get their hands on the RWD Korean 2+2. While some are seeking out the uplevel 300-horsepower, 3.8-liter V6 model, many tuners are itching to get their hands on the entry 2.0T powerplant. At 211-hp, the base model isn't going to win many street races, but countless mods promise to produce tremendous amounts of power with less weight.

Tuner Beyond Redline took apart the 2.0T to see exactly what Hyundai gave tuners to work with. For starters, the block is evidently sourced from the Mitsubishi Ralliart, which is different from the more structurally sound EVO X block. Beyond Redline expects the engine's sturdy components and 86mm stroke and bore to make 400 wheel-horsepower and rev to 8,000 RPM with the proper mods and a stock block. While the 2.0T gives modders plenty of room for overclocking, the engine's open deck block means that too much boost could warp the cylinders. Block guards can be used to reinforce the cylinder walls, but that means additional work and cash to really kick the 2.0T into high gear. Hat tip to Andrew.

      A Mitsubishi engine? That doesn't portend well. Also, an open-deck block? That's just like the Chevy Vega, which would run fine, as long as it was never allowed to overheat, which caused the cylinder barrels to pull away from the head. Of course the Vega used a cast iron head, which made matters even worse (different coefficients of expansion).

        Hondas are usually open deck. When executed properly it works well. It may present some limitations, but they apparently aren't a problem for most people.
        • 5 Years Ago
        Hyundai pakurid all other countries.
        Hyundai gets good estimation only USA where the people precedes low price and externals.

        HAHA...

        Please learn english. Even a KOREAN like myself can speak better English than you Japanese.

        Reading all your posts make me cringe. Translate that in Japanese. HAHA..

        Its actually a Mitsubishi/Hyundai/Chrylser engine. They designed them together.
        • 5 Years Ago
        Actually, it's a Hyundai engine. The article got it the wrong way around; the Ralliart's engine was sourced from Hyundai.

        All versions of the GEMA engine (Hyundai's Theta, Mitsubishi's 4B1, Chrysler's World Engine) were designed by Hyundai, with Mitsubishi and Chrysler making local customizations to the design. The Evo's engine had more customizations than the Ralliart's, which only deviated slightly from the Hyundai design. Hyundai later added their own local customizations when they launched the Theta II.
        • 5 Years Ago
        @JGP, actually the basic block has been designed by Hyundai but rest of the internals have been designed to each of the alliance partner specifications. The article is right, its Hyundai who sourced the final engine design from Mitsubishi (4B11T). When it comes to small displacement engines and turbos, no one does it better than Mitsubishi so I doubt they would need Hyundais help.

      So what the engineers sat down and said lets come up with a slick new 4 cylinder. Then they went to Honda picked up a couple F20 motors and copied them.

      If you have any questions for Beyond Redline you can ask them in the thread that this information was sourced from over at gencoupe.com

      http://www.gencoupe.com/engine/10524-our-2-0t-has-arrived.html

      Any and all questions regarding this engine can be found and researched, if not already answered over there. Likewise the 3.8 Lambda II.
      • 5 Years Ago
      In the plus column though I like that it has a timing chain. I've had a number of broken belts pretzleize valves in the 4G63s...

      I wasn't aware that some companies still made non-deep skirt, two bolt main engines...Come on, even the wimpiest of American V8s are deep skirt cross bolted engines...

      Edmunds has now fully tested both the Genesis and refreshed Mustang. Here's the nitty gritty and not-so-pretty.

      Genesis 3.8 Track

      60 mph in 6.4 seconds
      14.5-second quarter-mile at 97.9 mph
      68.2-mph slalom speed
      Skid Pad Lateral acceleration 0.88g
      60 mph to stop 111 ft.
      17.9 mpg overall

      Mustang GT Track Pack

      60 mph in 5.2 seconds
      13.5-second quarter-mile at 102.9 mph
      68.4 mph slalom speed
      Skid Pad Lateral acceleration 0.91g
      60 mph to stop 107 ft.
      17.1 mpg overall

      The four cylinder turbo Genesis performs even worse stock, it's embarrassing. How much money is anyone really willing to throw into a 2.0T to get it to equal a stock Mustang GT, 370Z, Camaro SS, LSX GTO, or any other number of RWD performance cars out there?

      Even after making it fast you're still driving a Hyundai, one that doesn't have it's vaunted 10 year/100,000 mile warranty anymore. And it's styled like a blob.

      Sorry, but the appeal of this car is lost on me.
        • 5 Years Ago
        Did you see the Mustang vs. 370Z? Better yet, did you see the sticker $ for the stang, and the also conclude that the Mustang works better at the drag strip.

        The Mustang is only 0.5 second quicker in the 1/4 mile over the Genesis V6 (see everyone else besides Insideline) and only by virtue of not shifting into 4th gear, premium, summer tires, 3.73 axle ratio, and revving to 6500.

        The turbo4 genesis coupe will handle the 4.0 V6 mustang just fine, and that is stock. Maybe for 2011 it will be upgraded, so it can handle the 3.7 V6 mustang.
        and it is the 45th year of the Mustang, 1st for the Genesis.

        @TriShield

        Edmunds tested 'full equipped' Mustang. It's price is $35,995.
        Ford Mustang 4.6 Engine is too big, and it's fuel economy is bad among the competitors.
        According to that test result, Mustang beat Infiniti G37 by performance.

        Genesis Coupe '2.0T' : MSRP $22,000 - $26,750
        Genesis Coupe '3.8': MSRP $25,000 - $31,000

        Genesis Coupe is still have price advantage than full equipped Mustang.

        And, Korean tuner tuned 2.0T gen Coupe to 362WHP machine.

        2.0 engine -> 362WHP

        Adding mods (even slight ones) to the 2.0L Turbo engine can make a WORLD of difference and still be cheaper than a Mustang GT. Just wait and see. And the 2.0L version hasn't even made it to U.S. dealerships yet so give it time will ya.
      • 5 Years Ago
      "Tuners" confuse me. If your going for power start with the V6, IMO anyway. Why would you buy the v6 mustang if you want performance? Ok ok it has a turbo (back to the Genesis), but you can stick a turbo on a v6 too and be ahead. I know not everyone can afford the v6 version, but if you really want performance it would be best to start there IMO. (Or just stick an LS1 in it :P )
        • 5 Years Ago
        Getting the motor with the most stick power often times isn't the easiest way to make big power. When you get the V6, bam you get 300 hp. You might be able to eek out 350 with tuning and aftermarket bolt on parts, but getting more power out of it is going to be more and more difficult.

        With a turbocharged car, you might only start at ~200hp, but get it tuned, you're up 30hp. Get a good exhaust, that doesn't need to be loud, and you're up another 30hp. Get a new turbo that takes an afternoon to bolt in and you're up 100hp.

        Simply put its easier to get more power out of a turbocharged engine than a N/A engine, not to mention that the 4B11 as used in the Genesis Coupe is a great starting point that many Mitsubishi owners already know how to tune.
        • 5 Years Ago
        More displacement = more gooder. I enjoy turbo cars but I dont race every day from point A to point B. I
        • 5 Years Ago
        @Alex
        You are then assuming that the Mustang's V6 is as overbuilt and has the same potential as this new turbo 4cylinder from Hyundai/Mitsubishi. It isn't.

        Also, it is much cheaper to overbuild a 4cyl then it is to do a V6 or a V8. We can't assume that the V6 has as much overhead left. ITs block and crank would have to be much stronger to withstand the same stresses because it has a larger heavier rotating assembly.
        • 5 Years Ago
        There's also the matter of weight and how evenly it is distributed. The four-cylinder Genesis Coupe weighs in at 3,439 lbs; the V6 model is 3,518, with most of the difference concentrated in the nose. Reducing weight by ~100 lbs is like finding 10 free hp, and you'll feel the greater benefit when you're steering into a corner.
        • 5 Years Ago
        Well, I'd assume the 2.0 is lighter, and it already has turbo bits.
      • 5 Years Ago
      stick a supercharger and intercooler on the V6...450 HP

      Now we're smokin'
      • 5 Years Ago
      The open deck design bothers me too, I noticed it in a magazine ad. Maybe the old Honda tuners will break out their inserts or maybe DART will make a new closed-deck block... guess I'll have to hope for amazing sales figures.

      How long till we see a proper 6 bolt 4G63 shoved under the hood of one of these? :)
        • 5 Years Ago
        I rather stick an ls1/2/3/6/7 in there. Lighter engine and a LOT more power and potential.
      • 5 Years Ago
      "RWD Korean two-seater". um isn't it a four-seater?
        • 5 Years Ago
        That's exactly what I was going to say. It's a 2+2 sport coupe, like the Mustang.
      • 5 Years Ago
      What is the big deal?

      While every ricer is thinking this is news the Ecotech 2.0 Turbo DI is aleady at 260 HP and the addition of a new Map and T Map with a flash brings it to a 290 HP with 340 lbs of torque at 20-27 PSI depending on conditions.

      Add to this that it is still covered by a 5 year 100,000 mile drivetrain warranty.

      Best yet the learn mode in the computer is opened so any other addititon will be adjusted to so the engine finds a true gain with them,

      The Ecotech STOCK internals can take:

      Cylinder liners 400 HP
      Rods 400 HP
      Valves 400 HP
      Crank 500HP
      Head Gasket 500 HP
      Rockers 700 HP
      Wrist Pins 700 HP
      Head casting 800 HP
      Block 1000 HP
      Head gasket 500 HP

      Yes these are conservitive numbers as to what the Stock parts can safely take.

      I would talk to John Lingenfelter when he was still racing the Ecotech 4 cylinder before GM moved him to the V6. He told me the HP numbers he was getting with the his race enignes and it was unreal. Many of the parts he was pushing were stock based or modified stock based as he was one of the first to tune this engine a few years back.

      Today I have one of the 290 HP Ecotechs as a daily driver. THis was my first 4 cylinder and to be honest I do not miss my V8's or supercharged V6.

      GM may not alway get somethings right but the Ecotech is one thing that they did do correctly.

      I am glad to see Hyundia to come out with a good engine like this as it will spurt the market in this green time to still give us fun cars.

      But keep this in perspective as this is nothing new. I think if you looked around there are several good 4 cylinders out their that will mod very well. This is just one more.


        • 5 Years Ago
        Who said it was anything new? 2.0L EVO's and STIs were getting 400 hp stock w/warranty years ago (albeit not in our market). This thing is RWD and cheap. That's new. What's GM have for 21K that's RWD and turbo charged?
        • 5 Years Ago
        There is indeed no big deal. The 4B11T in the Evo X is leaps and bounds better... and the 4G63 was a much better engine power-potential-wise, without needing reinforced cylinder sleeves or water jacket braces; but Mitsubishi wasn't about to use it for 20+ years like it did with the 6G72. The "Evo" engine needed a refresh for sure. Do I like the new 4B11(T) design? Not certain yet...
        • 5 Years Ago
        Scott, no one's saying the engine is anything new. Actually, what we're saying is that is reminds us of something old (Mitsubishi Evo engine). While it's more of the Lancer Ralliart, this is useful information for us. As a previous owner of a similar engine (Eclipse 2.0L turbo) I can say that getting over 400whp (at the wheels) should be possible and I believe this article is being conservative as well. Just cause someone estimated it to be 400whp doesn't make it fact.

        Also, it's not just the engine that matters. It's the whole package. This car has it. Not sure how many Genesis Coupe buyers are going to cross shop this with a Cobalt SS...
        • 5 Years Ago
        Well, part if it might be the vehicle it's in. Best thing you can do ecotec-wise is maybe a Solstice Coupe or a Sky. But a cheap 2+2 RWD coupe? Nope.
      • 5 Years Ago
      400 whp! Look at that Hyundai go!

      Korean automakers are on the rise, and what a turnaround it's been for Hyundai, from Sonatas and Coupes and cheap econoboxes to Genesis sedan and coupe which are actually cool cars.
