Why you Won't tune an all motor 4 cylinder - Naturally Aspirated NA build

[@DrewSlides]

Well now that you told me everything i need to do i’m gonna do it just because you told me i wouldn’t

[@oggramm]

Your knowledge is great but your voice is like a drone

[@blackericdenice]

He is just repeating what he seen online. A 2004 VW golf 2.0 make 115 hp stock. You can get this engine to 165 hp with bigger cam and stock compression.

[@Toxic2T]

NA > Turbo any day. You don't need big HP and torque numbers to have fun. Also, the snappy throttle response of the NA is unique.

[@MegaMechatronics]

They all have their place. What are your thoughts on air cooled vs water cooled NA engines? Air cooled engines can be pretty lightweight.

[@codycraig5998]

Must be a V8 guy and his stock motor still can't do 100hp per litter

[@randonauticanz4078]

I got 180bhp from a 2 liter engine that came out of the factory with 134bhp, all motor guy owners know a 50% gain is a pipe dream I'd buy a 10k evo.

[@Noooo23523]

chevy 5.7/6.2 do 700-1000hp na

[@konquer247]

I disagree with you if you're talking in a general sense. Not all 4-cylinder engines are built a like. Some engines are easy to boost like the mazda miata B6ZE(RS), or the Mitsubitshi 4G6/4D6 which can come as naturally aspirated or turbocharged from factory. What you said there could be easly misleading, just my thoughts.

[@shawnexotics7828]

I though miatas always came with 2R motors

[@Fred_the_1996]

thanks for the reality check i guess, I was thinking about building my rover k series, but now i think i'll just add forged pistons, shorter rods and the entire turbo system from a junkyard rover and slap a T25 garrett on there with like 5psi of boost... or, y'know, sell it, get a civic and tune that since it's cheaper haha

[@dannybodros5180]

[@sergeantseven4240]

Jokes on you, i would do it just to spite you... with all hand-made parts made with my dremmel tool and a hand saw....

[@Hoffmankustoms]

Not sure why you say i won’t tune a all motor? Yes you have to do all that and more but it’s still tuned. I’ve been doing these motors since 96

[@MegaMechatronics]

My original "script" would have been 20 minutes going into every system I talked about and as you pointed out I missed a lot as I pointed out too. And I'm not saying I left out details that you have experience with, haha I was eating boogers in 96'). I'd like to get your take on the next video of my opinion on why you Will indeed build a 4 cyl NA. The framework of this 'You Won't' video is you want your car to go fast like most 16-20's car kids, the framework of the next video is: we'll just have to find out ;)

[@yakima4x415]

Lol you are way off.. honda boys been building N/A 350-400hp motors for years. And you don't have to run more then 8,000RPM

[@MegaMechatronics]

Some car guys don't blink when they spend $10k, this doesn't mean it's a good value when you can get the same output for half the cost with way less effort. What's cool and effective is a high output NA engine no doubt, but physics is physics. And if you break a 350 hp N/A 4 banger, it's going to cost thousands again and many hours of labor. If you blow a turbo'd motor, at the least it's going to cost you a new-to-you junk yard motor, no need to open up the bottom end (like to check/file ring gaps). I've checked ring gaps 2 too many times and found used ecotec engines inherently have larger ring gaps due to a larger cylinder bore diameters, which I reckon is the case with all piston engines.

[@joelstatosky1817]

To sum it up the cost for the power isn't worth it like it is with a properly built turbo set up. Na is more reliable but reliability isn't cheap. When you get that $6000 dry sump just because you want a 25% boost you will relies that the reliability usually isn't worth it unless you are rich.

[@riorica1]

😆😆😆🤣🤣🤣 You just described my build at the moment. I'm building a 4 cyl motorcycle engine, and I am encountering pretty much all of these issues. The project is really cool, but it is difficult and the costs are mounting. I'm having to research so many new things which is cool because I am learning a ton, but I'm definitely realizing that this is a very involved process. I'm definitely glad that the outcome will be way awesome and that this is mostly a learning project for me as I am currently in school for working on bikes.

[@rex1800]

thats cool, where are you at now since you said you were in MIT or something?

[@nashdale6715]

BASICALLY U HAVE TO REBUILD THE ENTIRE ENGINE TO GOTIT RIGHT TO THE SPEC.

[@Soldier1287]

I just wondered about MAKING my engine naturally aspirated though. For longetivity. not crazy stuff. I used to think I just add a CAI and delete the cats, and retune of course.

[@Soldier1287]

so pretty much just buy a car designed from the ground up to do the crazy performance shit, cause that’s alot of mods

[@juanpreciado3789]

Can I do this on a 7th gen celica? Alot of people say it's almost impossible to gain HP

[@krazzymagic8128]

Yes you can, make sure you have the 2zz-ge engine though.

[@SashaM0915]

Here I was thinking to myself I’d maybe do an all motor build to a miata so I search how to make more power in an N/A and click this video and not even 2 minutes in I’ve completely lost motivation 😂

[@Master-Roshi]

haha same, so now i'm looking at Ecotec swaps lol

[@MegaMechatronics]

Part of me doesn't want people to lose their dreams (because dreams can cause forward moving actions in life and learning); however on the flip side I don't want people to feel the disappointment and regret after investing too much time and money into a project that won't satisfy expectations.

[@amcezm0n3y47]

does the maker of this video ever hear of the honda f20c or k20a? shit even the toyota 2zz or 20v 4age? these are all the things he is saying you ''wont'' tune already tuned. all high revving, high compression, high hp per lire engines.

[@addsomelotionaddsomemotion3279]

sounds like a sunday project.

[@ZacLowing]

So what you are saying is build a V-8. Cool, I agree.

[@williamhendrix2455]

my N/A 4 banger will never beat a V8 at a 1/4 mile straight but on the first curve or corner, I got you. 15k base price brand new 40mpg for 18 years.

[@kylapendley924]

Because 4 cyls suck so hard it isn't funny. Only reason. V8 are king

[@JaimeMartinez-bz6vt]

What I want to know is how much everything he said cost$$$$

[@denisdimitrov5051]

As the car you are tuning, brand new price. Turbo is more cost effective for power, but NA is more driver's oriented.

[@randonauticanz4078]

Over 12k

[@randonauticanz4078]

I got 25% power gain and 40nm more torque for 2.5k hes being unrealistic no N/A owner would never dream of making 50% more power, most owners would be lucky to squeeze an extra 20bhp from their motor.

[@randonauticanz4078]

Mate you're scaring people 50% gain on a naturally aspirated engine is a ridiculous target, I have a 2L N/A engine I gained 25% bhp and 40nm of torque my car weighs 980kg I've doubled my nm per liter by 100% it ended up costing around 2.5k what your talking about would cost over 12k, there are grey areas, try gaining 50% on a 400bhp evo see how much that would cost I guarantee the evo owner would stick at 400bhp.

[@adamammar7102]

How did you do so with only 2.5k could You list it out ? I’m working on a 2.0l Kia Forte NA looking to do sum damage on this one thanks!

[@verigone2677]

@@adamammar7102 If you can weld and know how to tear down and engine yourself, you can save about $5K from what it would cost to buy all of the metal work and pay someone else to buy and install your parts. If he has to list it for you to understand why it costs that much then the list won't help you at all. It goes something like this: 10Ft of 3" Stainless tube, 20' of 3" Tube various Mandrel bends or another 20' of straight tube if you have a proper bender, new fuel system parts and a micro squirt, throttle body(ies), TPS, MAP and other sensors. You shouldn't need an upgraded oil pump gear until well after you see other oil pressure problems in that engine that aren't solvable for less than 3K. Plain and simple, I am in the same boat as you, Veloster non-Turbo, Step 1: Intake, Throttle body from an Elantra Turbo, Cat back exhaust...let it breathe. Step 2 - Valve springs, Pistons, Rods, Bearing Sleeves, crank caps, etc - See KDM Tuners they have the best kit and probably already fully configured for your car. If you do not like the price, look at what they are trying to do and see if you can find those parts cheaper. Also, if you do Step 2, tune only to consistent smooth running do not tune for power until you update your Clutch/DCT Converter-Clutch assembly. Step 3 is port, polish, ECU, bananas power gains and MANY smoked transmissions...basically, beyond Stage 2 you need to be looking to lighten the car, take the suspension to the next level, and improve Aero as those gains can only improve the car without risk of making it unstable. If you want to get to the same power level faster and with a little less to build up, throw a small turbo with a piggy back ecu and a small intercooler, but you still have to change the pistons to lower compression and you should update fuel delivery, lifter springs, and oil temperature monitoring.

[@migguru562]

Yes I'm confused too on why you say "you won't tune"!!! You can tune any engine and depending on what spec you're looking for you can change one or all of components including modification to the head, block,ect... oh and solid lifters is an option too. With that said, your information is correct. Please change the title! Because people have and will tune their 4 cylinder N/A engines

[@MegaMechatronics]

Thanks for the comment. Please check out my next video on the Top 5 reasons you Will tune and build a high horsepower 4 cyl NA. I'd love to build one and share it in the future.

[@eriks87cam702]

Let me know if I’m wrong but almost everything he said for the first half at least is everything you have to do anyways 💁

[@MegaMechatronics]

No, you are just above average perceptive in seeing my job was relatively easy in that I just needed to lay it out as if someone truly wanted it to happen. Cliche' say: with enough time and money anything possible.

[@LB83.]

Actualy longer runners are better don't say do not tune n\a if ppl like more resposive car y not its costs more and get less but a small hatch for example wrc vs 306 maxi 306 whas faster on tarmac fwd n\a vs 4x4 wrc if u hear the 306 maxi pure sound is just🤤not one car sounds better exept the n\a lexus LFA and all u just said is=for a turbo build btw a turbo engine does not last as long as n\a even if the n\a hits 9000 rpm

Na has less partsso there's less that can break . factory motors , yes are often not built to spin at 8000 tons ... However look at the S2000 . 8 grand na . yes

[@Bombards.]

This video was actually really helpful

[@MO-oo4bq]

More rpms break easier . fast winde rate na requires less displacement . turbo requires more exhaust to spool them what a supercharger requires to work . turbo are better on large motors . auto manufacturers are putting out comics .

I am currently taking on the most unforgiving and money pit of a build... Non-Turbo Gen1 Veloster. But we are going to aim for 8500 RPMs to start and see if she holds up, going to be roughly 5k in parts and I am going to have to go in the woods to find port and polish Yoda, might even have to sacrifice a kid to get someone to work on this thing with me. At least I can fab my headers and exhaust, rebuild the trans, and do all of the other mechanical setup. My first dabble into MegaSquirt shall be ensuing soon...hoping not to drown.

You are going to come out on top whatever the result, because you're going to learn so much on this build journey.
