• Renntech already has the M133 inline-4 in the CLA45/A45/GLA45 AMG over 400 horsepower with Stage I tuning

      Remember when BenzBoost posted that the new 2.0 liter M133 AMG four-cylinder is underrated? Many BenzBoost users started speculating there would not be room to tune the motor or that it would not be tuner friendly due to its high amount of boost from the factory turbo. Well, Renntech is already showing over 400 horsepower with just their Stage I tune. The SuperFlow dyno shows 414 horsepower tune only (361 to the wheels) which is a gain of 25 horsepower over stock.

      25 horsepower tune only on an underrated 2.0 liter four-cylinder car with 26 psi of boost stock? Not too shabby especially considering this is just the beginning.

      The videos below also show the performance increase of the tuned car versus the stock car. 0-60 goes down to 4.0 seconds flat from their testing of 4.6 stock and the 0-124 mile per hour time improves to 14.5 seconds from 17.6. Very, very impressive.

      The cars with the M133 motor are going to be a lot of fun for tuners and a staple of the Mercedes tuner scene in the coming years.

        I never said it can't be tuned. I just gave you the figures that I know are going to be made. There is only so much a turbo can make bro. My gti had a turbo, my cobalt ss went through 3 turbos. My 335... lol you get the jist. I'm good with turbos Click here to enlarge

        Yes but on paper a four cylinder can put out more than enough power with a big enough turbo right? So this thing is hardly maxed.

        No.
        It won't.
        Why do you keep keep arguing this when everyone here who actually has any experience building cars knows it's true?
        I don't know why you are being so stubborn about this subject.

        You're implication being I don't have experience building cars? Or with tuning?

        Why do you keep prattling on about the M157? It's not getting it. Move on. The M177 may be better for all we know and I'm certainly not disappointed with the info so far.

        Probably because I actually have experience with the tuning scene, motors, and with a highly tuned 'tiny' V8 engine?

        The fact this 2.0 liter runs with a 6.2 liter LS3 says more than enough.

        You make my points for me.

        LOL bro i don't understand why this isn't coming to you. The turbo is already maxed out the way it sits. The only thing you'll get more is by upping the octane rating and adding a downpipe. It will barely move the graph to left minimizing spool time and barely adjusting peak hp. Just wait n see. @TT C6 and I both understand and know what were talking about...

        I believe this car has more power stored, when RENNtech dynoed my 02 MCS back in 2003 with their flash and we dynoed 175 whp out of a 1.6 Pentagon Engine , HARTMUT the owner of RENNtech was impressed with the numbers. That said I managed a couple of years later with better pulley at 15% from Mini-madness and a Light Crank pulley from M7tuning to finally crank out 197 whp and believe it or not I never changed the OEM IC imagine if I would installed a better IC I strongly believe I would of cranked somewhere around 210 whp.

        This turbo clearly isn't maxed as a piggy is making more power.

        Is there huge leeway? No. But also what I'm saying is you can put a bigger turbo on so what's the problem exactly?

        I don't know what I'm talking about? This car is already over 400 hp with just a basic tune and you guys we're telling me it was maxed. I wouldn't say it's both of you that know what you were talking about.

        People also told me the M3 was maxed from the factory. I'm sitting at well over double their HP.

        Of course it has more power in it Renntech already demonstrated that so hate for this awesome motor is unwarranted.

        It doesn't take a rocket scientist to realize a motor like the M157 has more power potential. But smaller turbo and direct injected motors are the future and so is tuning them. And this motor will be tunable...

        STICKY knowing HARMUT from RENNtech they are playing safe, when you order a FLASH from them you need to specify from MILD to WILD that said, as you stated this car has not touch the tip of the ICEBERG yet this is a prelude to more things to come. So people stop hating the car, it HAS potential but adversely FWD will not give it justice unless they come out with a 4matic version, THEN this car will trully be something to recon with!!

        Exactly, this is just the beginning.

        Haters? Potential?
        It's simple science that the engine is limited by displacement and maxed out from the factory.


        You guys are delusional.
        Ignorance is Bliss. Enjoy!

        If they already are over 400 hp how is it maxed out?

        You should these motors are going to be tuned A TON.

        IC, exhaust, intake, etc... Maybe it hits low 400whp.

        I think we're not going to see too much more on this motor without getting really hardcore with mods. There is lots of experience with tuning a 2.0 in the Subaru community. Here's what I found with a quick google search.

        well we had 480 out of mine, but a customer is running 520bhp on a completely unopened sti 8. Closed deck ej20's are especially strong and 600bhp would prob not be impossible

        However, and here is the crunch, 2L is simply too small for that power level. the lag is epic. EJ257 makes sense up to 500bhp, beyond that the EJ22T block is the way to go

        ***********


        Not entirely true. RCM (Roger Clark Motorsport) have an Impreza GC8 know a the Gobstopper. The engine is an EJ20 using Closed Deck Blocks, internals are all supplied by RCM themselves and runs a standard Subaru radiator they run 800+BHP using Motec Management. They have never had engine failure using this, lag can be compensated for depending how far you want to go and choice of turbos.


        All the above comes at a cost of course, but that wasn't the original question.


        I agree with the EJ257 statement though, but again depends which block you use as there are two available. There are also a number of stroker kits available for EJ20 and EJ22, also there is some news of one available for the EJ257 but I haven't seen it yet.


        Have a look on the RCM website for info regarding the Gobstopper, food for thought maybe??


        Regards,


        Keith
        Definitely will have to open up the wallet to get into the 5, 6, 700hp and higher range, but it is feasible even with 2 liters.
