I also never get tired of Moog playing the intercooler like a harp.... I don't know why, but it kills me every time!!!

[@EquilibriumEST]

+Patrick Morrissey it is because it is awesome :)

[@anndyman72]

Never gets old!

[@Peron1-MC]

really good editing actually yes :)

[@brandonhakki4798]

missing serial code on the turbo totally means it wasnt taken off a stolen car

[@CornishGuilt]

brandon hakki do stock turbos normally have vins?

[@brandonhakki4798]

Stock ones Yes

[@wejustskating]

brandon hakki so? 400 bucks m8

[@MichaelGuardiani]

brandon hakki shhh

[@RogueHedonist]

brandon hakki I've got a Hyundai Getz, 1.5 Crdi turbo diesel. It puts out 110bhp stock, I've got it aggressively remapped and got a free flow exhaust as well. It puts out around 160bhp now. Maybe a little more, It was 154bhp after the remap, I haven't checked after removing the cat cons and installing the free flow exhaust. I'm thinking of fixing a slightly bigger turbo, something that will help bump up my figures to 200bhp. I have 205 section tyre's already and am planning to upgrade my suspension soon. I don't have an endless supply of cash and hence would like to know, what Turbo charger would fit as a bolt on with no changes to the manifold etc. Do I have to install new injectors and a blow off valve? Can someone give me an estimate for the turbo supporting mods please?

[@robo1000]

I remember watching this 6-7 years ago and being sad I couldn’t do cool turbo upgrades and FMICs because all I had was a 03 NA Mazda 323F at the time. Now I’m on the other side. Got a sweet 2016 turbo sports car, FMIC, HKS BOV and just did a big turbo upgrade. You guys inspired me to always keep my dream alive and it’s not just a dream anymore. It’s real, it happened and it’s great!!!

[@EAADetailing]

I love going back to these older videos even back to the red micra videos, to watch how far you guys have come. The videos have always been amazing, but man the video quality sure has come a long way.

[@oldgregg6690]

lol at the tiny bump line you drew for modifying the heat shield and then just ended up cutting a big square out

[@WaterLines333]

I think that was just so they got a rough idea of what needed to be cleared, then made the hole around it bigger just in case. Or they just said "Fuckit" and made it bigger.

[@bigfishpondhome1]

Hey Mighty Car Mods, just in case you didn't already know, that rag actually says, "Road Safety" on it. XD!

[@pieterdeklerk914]

Thanks man I was scrolling through the comments to find out what it said it was gonna drive me crazy.

[@cloudvsephiroth215]

draws neat area for waste gate piping... completely ignores it and cuts off whole side xD

[@GioGuitarDude]

+Jacob Mortensen Yes that was quite funny.

[@GuzzyGeetar1]

draws template to clear Wastegate Actuator Rod - then realised the Rod bends and needs more clearance to function ;)

What if sneezing..was just a human blow off valve?

[@buca9696]

You don't sneeze after a quick sprint.

3:25-3:40 had me in tears, do we now know the origins of cheryl?

[@W0mpa]

I need a t-shirt with the text "You need big balls! Big ball bearings!" And a picture on a turbo :D

[@patrickmorrissey2271]

I never get tired off watching Marty try not to laugh, while Moog is going off on something..... Hahahaha!

[@turbolabamerica]

How much power do those turbos even produce? We usually build billet 16gs and 20gs for these cars. The tdo6sl2 7 blade 20g seems to be the best for spool time and hp capability.

[@Corcoran21]

hey guys, you should try out PB Blaster in future videos. It's supposed to be better than WD40 and I use it all the time. I never had luck with WD40, bolts would continue to strip off. So, my dad introduced me to PB Blaster and I haven't stripped a bolt since. It's a really good product. I'm not trying to advertise, but I'm pretty sure it could help you guys out with all the rusty cars you guys work on.

[@glass-man-2527]

Lmao I was dying when he played the intercooler like a harp!!!!!

[@HyperspeedMedia]

they call it "dump pipe" ...everyone else call it downpipe..

[@Wotm16]

I call it dump

[@spooln30]

Dump pipe is what most call an external wastesgates exhaust if not recirculated.

[@xe4743]

30spooln nah thats screamer pipe

[@kylebroome7593]

30spooln what Matt Sawers said. an external wastgates's ehxhaust f not recirculated is actually a screamer pipe

[@KianPalmer]

Sitha Puth Proper JDM vocabulary!

[@didaloca]

How on earth can you get under your car like that? I got axle stands ages ago and still shit scared of getting under there in case it falls on me :

[@Candisa]

Funny how the TD04 is considered a tiny turbo for nothing more than some punch down low on Subarus. On a Fiat/Abarth engine the TD04 actually a huge upgrade even from the 180hp setup, allowing for 250+hp.

[@Trissification]

Candisa well relative to the size of the engine and car, yeh it's all relative.

[@connorcox259]

i highly doubt you will get that power to the wheels on those tiny engines.

[@sanderk95]

@@connorcox259 1.6 or 1.8 Will be able to Lower engine sizes not sure , atleast the 1.8 20vt Will but that's VAG :')

[@bawalmagisip1]

missing serial numbers/code on the turbo. is it stolen?

[@gagesonny3048]

Probably just sanded off, because mods.

[@bumblebee7838]

All their stuff is stolen. Have you never wondered why they never film in the same location twice in a month?

[@sanderk95]

Modded hybrid turbo's or repaired turbo's with internals get sold without or with the company which reconstructed them

[@thevillageidiot70]

No they just filed the numbers off for weight saving. Every gram counts.

[@hcracer1985]

U guys need to do a video of eBay intakes vs name brand $200-$300 intakes and see if there is any difference in power!!!! Like this comment if want to see them to do one!!!!!

[@checkeredcheese]

Its already been done...

[@Azurren]

The only problem with cheap ebay intakes is, under pressure, poor weld snots can break off and enter your engine. (Not Fast n Furious style JR.)

[@gabebarnett3529]

hcracer1985 cold air intakes , usually help with forced induction means like a supercharger , you don't really use them just in their own because you might make like 2hp but they are meant mainly to keep humidity out of your engine because that means less power and are bigger than stock intakes so you can have more air going in

[@MrMitchell699]

[@jimhammer95]

that turbo is stolen for sure

[@jordanjay1479]

Didn't disconnect the battery. That's dangerous

[@flatback90]

you forgot to say oil prime the turbo!!

[@nitarsh]

So, if I upgrade the turbo, do I have to upgrade the intercooler, i.e., should I be worried about pushing the engine's limits?

[@TheDopekid7]

It is highly recommended that you do supporting mods when increasing boost but not necessary. It really depends but yes you are pushing your engine more by upgrading turbo

[@danielgonzalorodriguez1032]

angel olivares how would you do that!? I have a dodge neon srt4 with bov, bigger intercooler, slightly bigger injectors, waste gate actuator, throttle body 62mm, downpipe and diablo sport trinity tune. Stock turbo. If I want to get bigger turbo should I change something else!?

[@TheDopekid7]

Daniel Rodriguez Thats actually a pretty good setup to handle a bigger turbo and is what I meant by supporting mods. I guess I assumed you were going to upgrade turbo with everything else stock seeing as how factory turbo engines have intercoolers like you mentioned in your original comment. You're should watch the mcm vid of turbo supporting mods, more detail there

[@RPXXPR]

Daniel Rodriguez I'm not an expert, as I right this my car is at a tuner (I don't have the tools to remove the engine). However, my dad has taught me about cars since I was a kid, worry about Air Fuel ratio. If your running on the "lean" side it means you should have more fuel for the amount of air there is. Running rich isn't nearly as dangerous. Running lean leads to detonation, which leads to one final detonation. Always make sure you have enough fuel for your setup.

[@geemaan7357]

Do the turbo supporting mods first!! Your current turbo will benefit from these and you will get bhp gains.

[@alec6677]

They're like the Germans but from a different part of the world.

This guy bought a stolen turbo from ebay! LOL!

[@adamparker3616]

You do know that turbos don't have identifying numbers on them. Yes, they have a code that tells you the model, but there is no way to link it to a particular car or owner. They most likely ground the numbers off because they had reconfigured the housing, thus customizing it and making the identification number meaningless.

[@dennisleslie]

Spraying WD-40 on the head of a bolt is going to do squat.

[@skylinedrevn]

+Dennis Leslie Definitely does do something, gets into the threads and loosens things up. Currently doing that with a project car and without it i wouldnt have the progress im at currently.

[@ddemby77]

My turbo pushes more boost than yall can hold in your tires and its made by the greatest turbo company. Garrett. With a custom wicked wheel to a 5in straight pipe. You guessed it. I own a 7.3 powerstroke turbo diesel

[@connorcox259]

massive boost, massive torque, sloooowwwww speed

[@CetheOhannion]

I remember watching this 7 years ago when it came out for funsies. Now I'm rewatching in prep for a turbo replacement on my 2004 STi

[@WTGRacing]

"putting old bolts inside hoses to stop the leaking". oh my god thats so brilliant! ive always just crimped the hose in half a clamped it but that looks heaps easier. this is another reason why i love MCM

[@esko23q]

The edit on the install is amazing.. Taking it out is one thing.. now putting everything back well that's the fun part. 7hrs later ...

I was waiting for them to talk about a tune.. great job guys. Love that Forester

[@kocfkocf]

I find myself forgetting how well they know their stuff when it seems most of the time they're joking around and just having fun with whatever project they're on

[@wardocc9196]

Dont forget to prime the turbo with oil before operating under load. I'm surprised this wasn't mentioned, unless I just missed it.

[@DhavalDedhia]

2020 and still love the vids whether old or new ...

[@still34u]

LOL .. I love how Moog marks the heatshield precisely to the size of that water pipe, twenty seconds later Marty brings it back with a big old :D

[@joemac9997]

It was for the waste gate actuator rod

[@still34u]

oops . either way.. cut nowhere along the line :P

[@tonystanley5337]

Hey guys I have a big issue with big turbo modifiers. You correctly state that other mods are need to take advantage. I'd like to see a myth buster on big turbos, just changing the turbo (not pressure setting) and measure the power difference and any other effects. Engine power is generally made from boost pressure and not turbo size, the engine cares not what size the turbo is only the pressure (and temperature) in the manifold. As power evolves up smaller turbos become less efficienct and general more heat, but heat is generated by compressing air anyway (irrespective of turbo size). A good example is the Volvo red block with its TD04 13C, its perfectly capable of pretty much any level of boost for a standard engine at the top end. An estimate of benefit to go bigger is around 220BHP, but you might need more fueling to get to that, so I'm thinking that there is no benefit in only upgrading the turbo. Some modifiers talk about more flow, but I believe this is a myth. What is hard to quantify is the amount of heat produced due to inefficiency, that might affect the power.

[@prospeedracing]

Turbo kits are an amazing way to enhance the performance of a car. When installed the right way, a turbo kit dramatically reduces the emissions levels of a car apart from adding to the performance. These kits are highly useful for people living in hilly areas.

[@Hargak]

You will for two reasons, a turbocharger is an obstuction until it's spooling the bigger it is the harder it is to turn. The mechanical spooling up of the turbocharger takes longer due to larger mass of the wheel. That's the first reason, second reason is more air requires more gas, so you will need to tune more fuel. Boosting even at the same psi you will be using more gas as more cfm's are making their way into the engine. If you keep your foot out of it there won't be as big a difference.

[@mrrentaspace]

Or just being a person in general. McM have really helped me out a few times when I've gotten stuck on my build.

[@mattymagoo22]

Today as people begin to understand, how to better tune an engine you will find that as long as there is adequate fuel, cooling and the engine doesn't ping, on a moderate boost setting (around 6psi) engines will last for hundreds of thousands of kilometres. Regardless of the gasket, again explain to me why you would both install a thicker 'copper gasket' while also replacing the pistons, when both actions will have the same effect of reducing compression.

[@Tedlasman]

Installing a turbo is nothing like how easy you guys make it look. I just put in a vf52 in my sh fxt, and the oil dump took me 2h to connect.

[@MrYodamaster1000]

You guys are the best diy car modders!

[@cameronmullins9280]

doing my first Subaru lmao I have a whole new respect for them now. I have a 2002 forester with a EJ20X motor with VF45 turbo. struggling with the harness now but with a e85 tune on 1000cc injectors the Quad AVCS and twin scroll its gonna be choo chooing like a champ soon. I WANNA A PIECE OF GRAMPS LOL

Looking back in time I always wanted wrx so I got one. I’m happy I don’t live over seas, taking that turbo off with having the brake booster/steering fork in the way would’ve been a pain

[@chancecalkin2596]

they never mentioned what kind of engine it had (yes it has the boxer engine) but all they did is discuss the basics of how to swap a turbo. it can be applied to any turbo car. their new episodes talk about how to actually turbocharge a NA car. give those a look.

[@Mr34Noisemaker]

did u guys prime the turbo with oil? or was there already oil inside the turbo?

[@nicholi2789]

"You can use headbands or JDM undies, but make sure it's JDM so it's extra maaaad.." lol..

[@SushiPac]

Sweet I swapped a VF-34 onto my 2002 wrx . It is an awesome upgrade from the td04

[@Everyday-man]

Love to see more video done on the Forester! Some cosmetic stuff and more modds such as fuel pump, leads , plugs, intercooler and injectors. Would love to see what a few more mods would do. Your 180kw now, be sweet if that could help hit the 190-200

[@fockyoumang]

Saab 9 5 turbos is td05/gt1752 and they have plenty of torque and high end. And that's the linear 2.3L 12 or 1 psi and I bought one from eBay put 50,000mi on it and it still ran strong. Absolutely zero loss in performance, it actually felt like it was breaking in and spooled up faster every oil change

[@fockyoumang]

It's supposed to be between 12 and 15 lbs of boost

[@Skracken]

Errr no it's a TD04 15T stock on the B205R, B235R and B235L engines actually. The rest are GT17. In my stage 3 BP tuned 9-5 Aero boost comes on at about 1800RPM and it pulls hard all the way to the red line. So TD04s are good turbos for a basic tune, depending on the variation of it they can go up to about 350HP (19T). I don't know what version these Subies use though, could be a smaller one than on the Saabs.

[@fockyoumang]

Niklas Bergsten I'm looking at it right now it's a Garrett gt1752s

[@fockyoumang]

Niklas Bergsten well I had a B235R and the turbo that was taken off to be replaced was a Garrett and I got a eBay gt1752s and it would spool up faster and produce full boost throughout the entire power band. It was a circular 3 bolt turbine housing and went to a 3" v-band downpipe.

[@mattymagoo22]

The only way you will blow any seals out of your engine is if your piston rings are worn and allow blow-by which will pressurize the crank case. When you spoke about using a thicker head gasket there was no mention of a 'copper' item. If you go to the effort of pulling an engine down and replacing pistons to lower compression, why then would you need to put a thicker head gasket to lower compression again?

[@flamezoidtron]

I love how the divorced pipe partially bypasses the catalytic converter haha awesome

[@whateverman4200]

Really glad you guys made this vid now that my 06 Legacy GT just grenaded a turbo 150 miles from home -_-

[@goaliedude32]

You could probably sell those turbo rags for a lot here in the US. I'm sure there's a market if you put it online. Especially if it doesn't take 3 weeks to get here(still us).

[@bananabottles]

u guys switched shirts between the intro and ending.... i feel accomplished

[@mattymagoo22]

Since you are a Holden fan google CAPA perfomance, LS1 'standard engine' single turbo upgrade. Then after you finish reading that google big cc racing which makes a kit to bolt onto a standard Hayabusa engine (which has a compression ratio of 12.5:1). Both these kits have been installed to countless cars and bike with no issue on reliability. It is clear from the language you've used that you have no idea what you are talking about, I was just trying to help you out a little with proper info.

[@MangoSmoothie16]

fmic with a bov will give noticeable lag over a proper tmic. The air has to go an extra 3 feet and the bov let out all the pressurized air that was in there.

[@_Delta_P_]

if your car comes with a boost control valve operated by the ECU that only allows a certain peak boost ( mine is now higher because my car was tuned) can you put on a slightly larger turbo to take advantage of that? will the computer automatically stop the larger turbo from blowing your motor up? So say you have a TDO4 12t turbo and you get the car tuned to run a bar of boost... could you but on a TD04 14t and be safe? it would just have a different boost curve right and the power would just be in a different place in the powerband?

[@lachlanw94]

Would you guys ever do diesel videos? I have a Ford focus turbo diesel

[@magicUse]

you won't get turbolag with a front mount. The turbolag accurse with the bigger ugraded turbo, that often follows an upgrade intercooler. The extra tubing length wont effect the system, in a way you would be able to notice! - i bet the reason for a top mount rally intercooler is more due to the safety of the intercooler, then anything else!
