$3,500 Single Turbo Kit vs. $8,100 Twin Turbo Kit | HiLow

Feb 27, 2020
(car engine revving) - $8100 Twin Turbo Kit. - $3500 Single Turbo Kit. - Does more expensive mean more better? - Let's find out. - I hope our cars don't explode. - Me, I was just on fire. Oh my God. (upbeat music) (car engines roaring) (imitates a car engine) - Turbos! - Yeah. (laughs) We bought two almost identical Nissan 350Zs and have been modifying them to be fun daily drivers that you can take to the track. - One Z, moi's, gets a lot of cool expensive parts that I've always wanted and Nolan's car gets a bunch of cheap parts. - Then we test them to see which components are worth spending your hard-earned money on. - Brakes, tires, coilovers.

All of those things help improve the way your car interacts with the road. But we haven't made a

single

modification that directly gives our cars a mo' powa, baby. - So that's what we'll do today. Mo'powa. - Mo'powa, baby! My catchphrase, friend. (upbeat percussion tones) - The most important thing that comes with this bad boy, instructions. It's like Ikea. I put together a rack this weekend in my garage. This should be no different. (parts hitting the table) - Little children. - Little rowdy boys here. - Your

turbo

is bigger than mine. (bumps on the table) (plastic wrinkles) - Big

turbo

. - We also added a Tomei titanium exhaust. - So sick dude. -Yes, he is so sick. (Imitates car engine noises) - Now it may seem strange that James is running a

twin

engine and I'm doing a

single

, but there really is no such thing as a cheap

twin

turbo kit.

And we're more interested in comparing what you can get for different price points. - We're going to install these turbans, dyno them, and immediately drive 800 miles to Albuquerque, New Mexico to hit the track and see who does... A mo' powa, baby! - A mo' powa, baby! (rock music) - Turbochargers work like this: exhaust gases enter the hot side of the turbo, which spins a turbine inside. There is a shaft connecting the two turbines. One on the hot side, one on the cold side. The cold side draws in air from outside and expels it through this outlet.

The charged air is then passed through the charged pipe here, through an intercooler to cool the air, making it more dense. It goes into the intake and goes into the engine where it is then further compressed and then exploded, thus powering your engine. - Honestly, I feel like we can 100% get this turbo kit today. - Do you agree Nolan? - Very well, yes, you have 90 minutes, so. - Oh, we have 90 minutes to put this turbo kit on the Z or my wife will leave me! (upbeat music) - I hope this installation is a little deeper than theirs.

For an important reason. We are replacing our exhaust manifolds. It shouldn't be that bad, hopefully we can do it within two and a half days. I think that's reasonable. They are just auto parts. (high bass music) - Is he slacking off? - No. (buzzes and clicks) - I mean, like, you're squeezing. (loud laughter) - Oh yeah! - All right, we lowered our crossbar. Now we are pretty much ready to remove the subframe. Which are big bolts, the engine mounts. We have to disconnect the steering rack and then some suspension components. You're doing some sick training, dog. - Thanks friend, I'm starting a good pump. - All right, that's the subframe. - Speaking of subscribers, if you like this video, why don't you go ahead and hit the subscribe button? - Dink!
Alright, now we're on our straps at the top, the engine is hanging. We'll lower the car and then we'll lower the engine a little bit so we have more room here. Actually, I'm going to take the cats out first, then we'll do that. - Tiger is the number one cat in my book. - That's how it is. - Lions are cool too. - Lions are like smaller tigers. Lions are (beep) compared to tigers. - What? - It is true. - Oh my-- - Straight. - Yes. - Spend five minutes on the Internet looking for tigers. - The biggest lion in the world at probably a dollar 50. - Yeah. - Because this was a cheaper kit, we found ourselves in a situation where we were missing some hardware that was pretty essential to be able to install all of this at the same time. 100%.
So we had to go to the Tractor Supply store, which was just down the road. Pick up some grade A fittings we use to connect the exhaust manifold to the turbo and from the turbo to the downpipe. And now we can fully install the thing. - We removed the hood so you home viewers can get a better view of the engine bay while we put the turbo on. Yes, we do it for you, okay? - This is a very narrow engine bay, not a lot of room for activities. - Or hands the size of a man. - So, to get a little more space, we will lower the engine. - This is basically what we've been preparing for all day.
Getting things out of the way. We've got some coolant lines out of the way, subframe out of the way, engine mounts disconnected, exhaust off, all of it, to get to this point. Andy, do you want to hit him? We're going to jack the car up and the engine will stay where it is for a few inches. That will give us more space from below. - So far it has been a day of taking things off, which is not so much fun. More chirps than putting things. But we're almost done taking things off and then we get to the fun part. (deep bass music) - Once the oil goes through the turbos and needs to go back into the pan.
So instead of having to play this thing, Jim Wolf's kit comes with a spacer. (clunking) (thud) (air hissing) - Single women, all single women, oh oh oh. (humming noise) (happy music) (lower yelling) - Alright, we spent like four hours trying to fix the clamp problem. We have some real v band connectors here. This feels like a much more solid unit and you know, I hope it works out, because otherwise we're kind of screwed. - So far our kit is-- (metallic whirring sound) - It's going up. He doesn't want to go down. - Are you okay? - I mean, hopefully.
It went up by itself. Like a (beep) ghost. (metallic whirring noise) Oh, why did we get the cheap elevator? - Those guys can't rest. So... (metallic whirring noise) (deep bass music) - So our debris gate hits our subframe. What we're going to do is put the waste gate back in a down position, like this. Fire will come out of the bottom of our car. And on purpose. - Our collectors are finally in place. It took me longer than I expected. Now we need to put some bolts on the turbo manifolds so the turbos have something to mount to.
The moment we've all been waiting for. Snail is going to enter his house. - Yes. - I have the nuts that I will give you. - So, the decision I didn't want to have to make. We try harder, - Everything. - To make this work without removing the air conditioning and we're going to have to do it. And I'll have to drive to Albuquerque with the windows rolled down. (downbeat music) - The turbos are on! T-T-O, turbos technically on. T-T-T-O, that's the code T-T-T-O for everyone. Mounts for twin turbos technically on. (metallic clanks) (bass music) - Because it makes sense to prioritize the O2 sensors. - Ok. - I'm not sure if it will, but we can try to see if it fits. (clunking) Since we don't have directions, we don't know which way it's going. (high bass music) - It's wedged between the engine and the rest of the engine bay.
It's just a very tight fit. (hammering) This car was super fun on its stock power. - All this has been very tedious. It's been a lot of ups and downs. - Right now this is not worth the money. Not worth it. - But as we've been saying all along, it's a very cramped engine compartment. - We lack hardware, the (beep) does not fit well. - This is going to leak. - But, we're doing really well, so. - We've tried every way so far on the down tube, it doesn't fit. So, let's tweak it a bit. (hammering) I hope it works. (upbeat music) Bad news.
We were trying to put it backwards the whole time. Yes. - It makes sense to do it that way. It makes sense. - And I just want to-- The downspout has to go through it. It's something so simple that we didn't realize it. It does a little-- It takes a little breath away, but hey, we'll be back tomorrow. We'll hook it up, we'll do the turbo. I'm over it. (guitar music) - Riding my gangster escape. Look at these welds, baby. This thing is so light. (Imitates a car exhaust) - No, you can do a better VQ than that. (Imitates the exhaust of a car) - It seems that we have run into another problem. - I feel like we can 100% get this tube kit today. (laughs sarcastically) The problem is, this is like everything they've given us for our drain and they're trying to put the oil back through the same plug in the oil pan where the pressure sensor is.
So we'll need to find a solid solution to return the oil from the turbo to the actual pan without clogging up too much space, but we're time constrained so we'll see what we find. with. - I just opened the exhaust box and our exhaust doesn't fit. - Does not fit? - No. - Oh man, that's... (laughs) - What we're going to do is use the exhaust that came on the car, which wasn't the original exhaust to begin with. Someone went into a store and the muffler was removed. And it already sounds pretty good. (metallic whirring) (guitar music) - And you'll do maybe, like, half a turn and then move back a little bit.
Half turn, small movement back. (popping noise) That doesn't help. - Can we get some working tools here? God, I'm sick of this shit. - I think that we are not really going to have any problems, there are still big problems. I really shouldn't say that, but that's how I feel. They may feel a bit doubtful because they have had problems, but sometimes it is. Especially when you're buying cheap parts. - Well, we ran into another setback. I feel like we can 100% get this turbo kit today. The plug we were provided with to drain the oil from the turbo back into the pan is actually aluminum and our pan is steel.
We are definitely not going to drill any holes in the block of our VQ to put the aluminum plug in there. So, we're going to have to think of something else. - We are connecting the interior cooler. It's really a piece of trick, it fits very well. I mean, look how the shape of the car follows. - We are going to relocate this plug, which we will use to place the factory narrow band sensor. So, we're relocating it because we had the sensor here, but it was squeezing another tube. So we're relocating it here and that will give us room to install it without hassle and allow us to run all of the OEM sensors.
It has been a long day. - That will work. - Now that we finally got the downpipe and exhaust installed, I feel like we're in a good place right now. You know, when you're hiking and it takes forever to climb a hill, by the end of tonight our hike will be over, our turbo will be on. Hopefully we'll be able to get it up and running and I'm really excited to hear how it sounds. I think it's going to be evil. - I feel great, I look great. I think we're going to be fine. - And I feel that they also feel better. - Yes, I just went there.
Things are looking better, things are bolted on, there's a turbo in there, they're getting ready to work on the intercooler. - I feel like both teams are at the point where we're almost done. - Yes. - And there's so much... - More tension. - More things to do. - Oh, sick. - Hell yeah. - Turbo back together. I hate waiting, you know? This would be so much more fun if we had all the parts in front of us. - Right. - And we could get serious, but we can't. We're kind of waiting and then like, oh, we find another soft spot to find another part.
It's very frustrating. - We put everything in and it didn't quite fit. So now we're just cinching and trimming a bit. And the hood is banging right here on the air cleaner and if it is then it closes, but without pipes there's no way it can droop like that. - Just push it. - If you'd like a tour of the store, you can... - Sign in? - Sign up for one. -So ours is underdesigned and his boys' is overdesigned. - Give it a try. (hammering) Ken, that sensor comes out, in that position. Oh it worked. - Be sure to prime it if you are installing a new turbo.
To do this you will unplug the ECU and then you will turn the key so that the engine turns without starting. - And we do it so that oil pressure arrives. You need oil in the turbo so it can spin. - Or he'll seize up, he'll burn. It is as if the French took over France on that day of robbery. - Clever? - Yes, plug it in. (the car engine spins) - I hope that when we connect the ECU, it will start. - We're putting some duct tape on the charge tube because it's too small, they didn't give us the right couplers to complete this kit without, you know, modifying it in a really bad way.
But, this is what we have to do to make this work. (pulling at tape) - Alright, well, the oil pressure light didn't go off, but that's definitely enough crank to prime a turbo. So, we'll go with that. I believe thatEverything will be fine, but... We just put a lot of aftermarket stuff on this car, so anything could be wrong. - Okay, the master airflow sensor housing we bought last night to complete our intake side of the turbo is too small. It's the wrong part, they sent us the wrong part. Maybe we didn't ask for the right part, whatever.
Anyway, as you can see, the flanges are very different in size, but the diameter of these internal openings is the same. And what we're going to do is tilt it a little diagonally and snap it in because we're just (beep) done with this. (laughing) (closing the car door) - The moment of truth. (car engine turning) - I want to make sure that whatever. I don't know, I'm... As if this wasn't a bit, I'm legitimately pissed off. I mean, what were we thinking? What were we thinking? (metallic whirring) - However, I'm sure some fit in here. - I think probably. (gravel crunch) (car engine roar) (upbeat music) - Alright, we're here at NM Imports.
Finally we are going to put our car on the Dyno. Let's see how much power it generates. I am very excited. I have a newly discovered fourth wind at this point. That was honestly the longest ride of my life, back to the point. Let's tune the cars. Let's get our uprev system working perfectly, these guys know exactly what to do. I don't know if you've looked around here, but there are thousands of Nissans and they say they know almost everything about uprev. So I hope this works out and we can have a car that we can really put our foot in and have fun. (car engine roar) - Two major concerns are the stock injectors running out of fuel and not much heat management around the turbo.
I personally like twin turbo kits because they keep the heat where the cats were. With a lot of the cheaper stuff there isn't much quality control, you have to be quality control if you're going to buy a cheap part. This is the MAF we had on the vehicle, but you can tell it's probably the correct MAF for the kit. Because these are the pre-drilled holes and then there are holes drilled for a smaller MAF. I am sorry. - Everything is alright. (laughs) We were in a time crunch, it's definitely not ideal and it's a perfect example of it biting you in the ass. (car engine roar) - I can't take much more of this.
I think we're on the right track, finally. - It's hard to hope, - It's hard to be sure. - At this time in our lives. - But that's three good runs in a row with an OEM Nissan crankshaft sensor. I'll take it to the track and see what happens. (car engine roaring) (upbeat music) - So after 800 miles, multiple breakdowns, and the longest week of our lives, we've got some numbers. Baseline first. Hello car started with 212 horsepower. The short car started at 244. We're not quite sure why we started with a 30-horsepower difference on identical cars. The low car had a muffler delete and a cold air intake.
We don't think that makes much of a difference. Perhaps the low car, ironically, held up better than the high car. (car engine roars) How much power did these two turbo kits add to our cars? - I'm looking forward to it. - The numbers please. Thanks, Jesse. After your unique turbo kit from Ebay, - Really building it. - You finished with a whopping 302 horsepower. You get a nice 60 horsepower gain. - Yeah, it's 60-- - Almost killed yourself on 60 horsepower. Hi car with Jim Wolf turbo kit done... 334 horsepower to the rear wheels. The Hi car started with 40 less horsepower than the Low car. - 30 horses less. - Short car added about 60. - Tall car added a whopping 122 horsepower.
I want to point out that both cars had stock injectors. - Yeah. - We don't have a big reason why we did it other than the fact that we ran out of time. - A production oversight. - Yes. - That, there have been many. (laughing) - We learned a lot in this episode. So, Nolan, boy. Does more expensive mean more better? - I have complicated thoughts about this. - I also. - The Low turbo kit was... - I mean. You saw it. - Yes, I lost hope several times. However, I got it back thanks to the power of teamwork and friendship. - Yeah, so... - Even a simple diagram would have helped a lot.
I'm sorry, James, I'm going to move on. In that sense, more expensive means more better. Where I'm not absolutely sure more means better is the bottom line, because we didn't... We didn't have the matching injectors. - Yeah, once we get the injectors we'll both be up against the 400 horsepower limit. - Yes. - For stock interiors. So at that point it's just single turbo versus twin turbo. Answer the question! - Yes. - Answer the question! - In that sense, yes. - What are you, a politician? - More expensive is better, for now. (chuckles) - You should run for the Senate.
Which would you buy, Nolan? - Well now that I know how to do it I would go back to get the low turbo kit. Yeah. Now that I know, I could do it again pretty-- - Yeah. - Pretty fast, I think. I wouldn't buy either one. I think the Jim Wolf kit is great. - Oh, I didn't know it was an option. - Yeah. We could have put a 2J on any of the cars, we could have put an LS. - I'm going to put those injectors there, let's adjust it. You will soon see this baby at some Pro-Am events. - You're going to drive it once and it's going to explode. - No. - If you're wondering why we went to Albuquerque, New Mexico.
You will find out in the next episode, where we take both cars. They both complete cars and put them head to head. A $13000 350Z build vs. a $41000 350Z build. It's a very, very funny episode and it's the conclusion to this season of Hi, Low. - Hello, Low - So make sure you don't miss that. Follow Nolan on Instagram NolanJSykes, - Thank you. - The J stands for James. Follow me on Instagram @JamesPumphrey. And of course-- - Follow Eddy @-- - Follow Eddy @-- - Edward Scedward. -Yes.-Eddy_Esparaza, I forget what he's up to. Be good. - Love you.
Hold on, hold on, hold on. We won't let you go without seeing some racing, so check out this drag race. The results may not surprise you. - Give me a rev. (car engines rev up) - Damn, damn! (upbeat music)
