Welcome to another episode of Mighty Car Mods Proudly supported by Just Car Insurance Now, last episode Marty revealed his very uninspiring new car Which was a Volkswagen Polo Which he decided was rubbish For what he needed it for MARTY: That's right, and I may have mentioned last episode that I have a new car And it's about time, Marty, you showed us your new car because it's taken you too long to show us And we want our money back! MARTY: What do you mean, "your money back"? You pay me. MOOG: Dude I want my money back for my YouTube subscription cause you took too long to finish your car and I've been waiting MARTY: You haven't paid for your Youtube subscription Anyway, I completely understand Why these cars have a cult following and here is why MOOG: Why Martin? Oh! We're gonna show a sequence Of what it's called and then... Okay cool MARTY: Because we cut into the bit where I say, (Random mumbling)... MX-5.... ♫ old car MARTY: That's right, I got myself a MX-5 This particular model is a 1990 Australian delivered Mazda MX-5 It's got hardly any luxuries with no power steering and a only a few of them ever came with air-con Its also got an open rear diff Which means it can be a bit difficult geting that lack of power to the ground. Its one of the best selling Two-seater sports cars ever made And I can completely understand why. 1.6 litre engine in the front Double overhead cam Driven wheels at the back Two seats, completely impractical. But as a driving experience It's some of the best bang for buck You can get in any car. This particular example, I've saved it from the hands of the wreckers A friend of mine rang me and said "There's this MX-5 for sale It's not in the best condition, its been outside for most of its life Do you want it? It's got rust in it." And I said of course I want it if it's got rust in it... Anyway, so I bought it and I fixed it and I've completely fallen in love with it It is such an awesome driving experience But there is one Very very big problem, with this MX-5 and most MX-5's It is so, slow... So slow! See, there is a good thing for all problems in this world, there are solutions And some solutions involve compressing air! MOOG: Oh Martin! ♫ Are we going to do the episode ♫ ♫ that people have been asking for ♫ ♫ for so many years they have been saying? ♫ "Please, can you show us how to turbocharge a car?" So that's what we're gonna do! MARTY: Oh yeah.
MOOG: WHOOOOOOOH! And, we're gonna be getting hippy on y'all, because we're going to be using recycled shizzle, not like olive oil and recycled condoms, but recycled bits from around here, with some custom fabrication! We're not buying an eBay kit! And, Martin, it's not for the.... MARTY: Faint-hearted. MOOG: It's not for the faint-hearted. MARTY: It's a big job but it's completely worthwhile, and this is the... So excited I almost fell over. MOOG: You almost vomited into your own mouth. So come with us on this amazing journey of discovery. That was awkward, Martin. That was really freakin' awkward, man. MARTY: So we are going to be turbocharging this MX-5. MOOG: We are in the Sunshine Coast which is not sunny, we want our money back, it sucks massive unicorn wang, and we're up at -- where are we, Martin? MARTY: We're at AM Auto, with the turbo-charging Yodas. MOOG: That's right, this is the home of the Yodas of all things that go "Choo Choo." And, we're turbocharging the car in one day. We're driving in N/A (Naturally Aspirated) we're leaving choo-choo. It's gonna be mad. OFFSCREEN: The MX-5 is rolled into the shop. Never again to be a naturally aspirated powered car. MOOG: So, Turbo Yoda, you've been doing these turbo things for around 10--15 thousand years now. Can you tell me what the difference is I mean? One of the reasons we're here, of course, for your Yodaness and classiness Is because you can make these incredible manifolds And apparently, you know, you've got a name in Australia as the best. That's what I've heard, which is why people call you the Yoda. ♫ Turbo Yoda! Awwww! He's the Turbo Yoda! ♫ Can you talk me through the difference between doing something like this as compared to buying a cheap one off eBay? What's the deal with them? ALAN: All right. So we're making our manifold out of a, raw materials So it's very strong. Um, you can wield it up so it's self-supporting. It's not going to break very easily. The manifolds that you buy for cheap, that are all shiny, look great, They usually just mig welded together By a chap in china And then they go, they top 'em with a pulse stig welder so it looks all dotty and shiny and stuff MOOG: Yeah right. ALAN: Inside 'em there's often filled with stalagtites of weld that break off and destroy turbos and that sort of thing has happened. MOOG: Horrible. ALAN: Multiple times. MOOG: All right. You've seen that happen? ALAN: To us. <chuckles> MOOG: All right! Okay. So, what, customers come in and they've bought them and go "Why doesn't my car work anymore?" and you say "Because you bought an eBay manifold." ALAN: We've fitted them and lost a couple $3000 Garrett turbos. MOOG: Wow
ALAN: ...because of it, so much fun. MOOG: Right, so, I guess by doing it this way, I mean, because one of the other things you can do with the MX-5 if you wanna keep the flange you can just chop through, right?
ALAN:Yep. In this case the MX5's manifold, it's got a tubular manifold that's fabricated, So in this case you could've just lopped that off But we've already bought a flange cause we didn't know that So that's a savings that could be had. MOOG: Okay. Yeah.Good to know. So obviously, if you are gonna buy one off eBay, the shinier, the worse it is. ALAN: That could be the case. OFFSCREEN: There's a whole bunch of parts in the engine bay that need to go because they won't go choo-choo and they won't go (HIGH PITCHED) "Stot-tot-tot-tot." MOOG: Okay, so probably the most common email we get is people saying, "What do I need to turbocharge my car?" So we've laid it all out. We're gonna show you exactly what you need. Starting with danger to the manifold. MARTY: Exactly right. So that is a manifold off an MX5. Normally the pistons just put the exhaust gas through those holes And it goes out there, and into the world. But, that's no good for turbocharging. We need one of these beauties. And that's a turbo manifold. So instead, it shoots the exhaust gas into there, and up into the turbo. MOOG: BUT! That means the turbo can get very, very hot, Martin. and so what's required is something to keep it cool isn't it Martin? Marty: That's exactly right MOOG: Something like this...something like some new gaskets. Something like some water lines Something like some banjo bolts Marty: But they don't just need water they also need turbos need an oil feed so that's an oil feed line uh on the MX-5 block lucky there's already an oil supply there so you just tap into that send that into the top of the turbo MOOG: and then! bung that into the sump, which will be the oil return line from the turbo. But! We want to have the air cool don't we Martin? Colder air is smaller than bigger air, that's how hot air's balloon. That's actually the opposite of a hot air balloon... uh front mount intercooler that's going to cool the air down so that what goes into the engine has a bigger "bang" with some pipes on it you've probably seen them before on a VL Commodore Marty: Exactly right but all that's pointless unless you have a way to tell the engine exactly how much fuel it needs so you need an ECU. You have to have some way of controlling the fuel so we're going to use a Megasquirt Plug and Play plugs straight into the existing loom we program with that and a laptop and the last thing you need Martin is a mate that had a Forester who upgraded his turbo to a VF-34. He is going to give you his TD-04 for free. the turbocharger. Now you can see why people call that a snail it actually looks like a snail in fact do you know what the worst job in the world is? Marty: Um...cleaning a stripper pole in an all male strip club? MOOG: Dude even worse! Snail dentist. do you know how many teeth snails have? Marty: No? MOOG: 14 thousand! Marty: They do not have MOOG: They have...dude that is a fact Marty: There's no teeth MOOG: Snails have 14 thousand teeth not only that do you know how long a snail lives for? 15 years and here's the freakiest bit *silence"* Marty: yeah MOOG: Do snails have a penis? Marty: no MOOG: Do they have a vagina? Marty: no MOOG: You're wrong on both accounts...they've got both. they're hermaphrodites when a snail meets another snail it just changes its bits so we're going to get you some number plates "Hermaphrodite" for your MX-5 Marty: Can't I just have MOOG: Because it's a snail Marty: Can I have turbo MX or something? MOOG: No "Hermaphrodite" for you and your MX-5 because the snails have a penis and a vagina Marty: I don't want a turbo anymore ♫ So Al the Turbo Yoda and myself are going to start by pulling apart this side of the engine the airflow meter's gotta go, the exhaust manifolds gotta go were gotta make some room so we can measure everything up for our maaaddd turbo install we need to remove all the parts that get air in and out of the engine cause were going to be changing all of it Now, in case your wondering why i'm also keen to get rid of this thing that is an airflow meter and it's a particularly old style one its called a vane airflow meter and it actually literally has a tab in there that moves when the air is sucked through it, now it's not hugely efficient but it does work, and they dont break down compared to the traditional kinda hot wire air flow meter's but were happy to get rid of this because the new setup is not going to use an airflow meter, its going to use manifold pressure revs and inlet temperature up to
calculate exactly how much fuel needs to go into the engine and reference the map but this is going in the bin, which is super exciting next up the exhaust heat shield an o2
sensor need to come off so we can remove the non choo-choo manifold in keeping with our combie driving
organic earth coffee meditation hippie style build, Al digs out a used silicon joiner for the intake that's going to come out of one end of an intercooler yep so this is the engine breather, which obviosuly cant go on the pressure side anymore its got to go into the pre turbo side of the engine Otherwise boosted air goes into the motor rather than oil coming out its looking bare already Manifolds gotta come off, all the intake stuffs off you know have made specially for us x-force the muffler, x-force big muffler Big Tip!!! you can almost fit your hand in there, look at it there's your nice wideband, you like that yeah and so our dump will go down in there take the same path as that through there Awsome!, but instead of just coming out of cylinders its coming out of a forester turbo yep so much better best thing about his forester I going to use that there's a heap of room under there for an intercooler isn't there there just not much room for piping this is a spare intercooler I found is that going in our mazda? I think it will fit it pretty good aw look at it go chop a few bits off and it will go nicely you can see it's been previously
modified that's alright, we like recycling, this turbo conversion is all about recycling good for the environment So the next choice we've got to make is where there our intercooler piping is going to be alloy or or whether its going to be stainless steel now alloy is cheaper, and its lighter but its hard to do good clean weld's on now stainless steel is heavier but its stronger and its heaps easier to do mad clean welds on plus it's not going to get holes run through
last touching stuff in the car which does happen the ah the the turbo yoda tells us that
apparently that happens all the time with this and we don't want
extra holes where there should be a hole cuz that's us rude so we're gonna go with stainless steel, hello we aren't using the whole front section of the of the original exhaust so it gets removed and disposed of
thoughtfully Bye Bye, definately dont need these there's tonnes of space man, its made for turbo lets have a look and we have to make a manifold to join him up twist that around add a thing on there gets some boost control and some water were going to basically rotate the core because were going to lay the turbo on its side, because that's basically how it fits the best that's the king of Man TT 04 you can see
that's the turbine that's when the exhaust fans and that's
the compressor wheel which compresses that then goes into the engine we have our oil feed and drain as well as the coolant pipes to keep it cool now this is a 2876 you can see the massive size difference
that was on a subaru this comes on a Subaru 2.5L Forester I was almost you know mine
TIL a snail have a penis and a vagina, from a clip about turbos.
