Turbo upgrade

[Ksnau]

So my budget's not going to permit this for quite a while and I have other upgrades that I want to do first, but I know back when I had my Ford escape 2.0 I was looking at trying to fit one of the focus ST upgrade turbos but it was really expensive. It was like 2200 just for the turbo and then you had to get like an adapter and it was externally wastegated So you had to get one of those too and then you had to figure out how to get the wastegate outlet back into the exhaust pipe routing and it seemed like a big pain.

So I was just messing around looking at stuff. I'd read about a guy who had upgraded his Maverick 2.0 turbo with like a Lincoln one and I was trying to figure out which one and I ran across this where Garrett has a direct bolt-in upgraded turbo for the 2.0. it doesn't say for the bronco sport but it does say it's for like the fusion and stuff and as far as I know it's the same turbo and it looks like the same turbo. And it just seems like a really cool way to increase power.

It says it's rated for up to 350 horsepower at the crank. Of course you'd have to get a special Dyno tune until they become more popular and then maybe some people would have canned tunes for them. But this is definitely going to stay in the back of my mind. Maybe maybe a way for me to waste my 2025 tax refund and void my warranty.

I assume you're warranty is expired, as doing this type of upgrade would certainly void it.

Ksnau have you finished the upgrades you listed in your other thread? Or are those on hold do you can go down this road? It seems like your other upgrades would be a waste of time if you do this.

What is your goal? Increasing HP with a bigger turbo like this will almost certainly come at the cost of driveability. The twin-scroll OEM turbo is designed for rapid spool up to provide maximum torque at the lowest RPM. Larger turbos typically require more time to spool up; you'll get more power, but you won't get it until you're higher in the RPM range.

So again, the question is what is your goal? If you're running quarter-mile races, this turbo--assuming it's properly installed and the engine is tuned to take advantage of it--will reduce your trap times. If you're running Baja-style races this turbo will be great; you'll get more power for those long, high-speed runs. For typical off-road trails, however, this turbo will not help. The Bronco Sport doesn't have a granny gear, so it's dependent on the abundant low-RPM torque made available by the twin-scroll OEM turbocharger. Installing a larger turbo meant to produce power at higher RPM and will likely reduce available torque at the RPM range used for most off-road trails.

A lot more than just bolting on a turbo. Fuel trim levels, and boost would have to remapped. Hours of dyno time to get this mod to work reliably.

JMO but the 2.0 has plenty of power for its intended use.

Agree with everyone saying this would be more trouble than it's worth.

Since I'm here, have you all seen the turbosmart dual port blow off valve? No idea if that would achieve anything or if is just a waste of money.

Since I'm here, have you all seen the turbosmart dual port blow off valve? No idea if that would achieve anything or if is just a waste of money.

Here's a short video explaining what a bypass/blowoff valve does.



The bottom line is you will not get a significant change in power by replacing the OEM bypass valve with a blowoff valve. What you get is pressurized air vented to atmosphere--making that distinctive PSHHHH sound--rather than being routed quietly back to the intake system ahead of the turbocharger like the OEM setup.

As an aside, I was watching a video of a Mustang EcoBoost owner showing off his new exhaust system. He was revving the engine so you could really hear the exhaust note. He also happened to have a blowoff valve installed, so every time he revved the engine it hissed like a cobra when he let off the gas. My wife looked over my shoulder as I was watching the video and said, "WTF is wrong with that car?"

"Nothing," I said, "the owner installed a BOV so it would make that sound."

"Why in the hell would anyone want their car to make that sound?"

It was at that moment I knew a BOV was not in my future...

It’s the transmission/driveline you’d have to worry about more than the motor. Smashing 400hp/tq ish+\-through that thing. This thing torque steers like mad stock. Be fun to drive though.

Do it OP!!!

So I'm pretty sure I covered most of that in the post but I know I have terrible writing skills so I understand if you don't want to read my whole post.

I'm not going to be doing this for years if I do it at all and yes you still have to get it re-tuned which at a good shop the going rate is about $1,000 the last time I had one done.

Also, this isn't some huge 88 mm turbo. It's slightly bigger and it's supposedly a direct bolt in so they couldn't have changed very much and it gives you the sizes of the compressor and turbine wheel and they're not that much bigger and you can see that the housings aren't really changed so it wouldn't affect drivability and honestly if you do it right it shouldn't anyways, I mean yeah if you put a huge turbo on there, it's not going to spool up right away but this isn't that.

And no this isn't going to affect the other things that I'm doing to my car even if I was doing it right this second which I'm not. I got my oil catch can line routing figured out I just need to get one more tee fitting and I'm going to be tapping into that line to reference boost off the intake manifold and then I just get a figure out the electronics. I'll make a video showing how I did the catch can too so other people can do it just because I'm also doing the boost gauge and because my catch can is actually from another car years ago. The fittings on it are smaller so I had to do some weird reductions in the vacuum lines so it doesn't look as good.

I've kind of figured out the wire routing too but not the source of power and ground and there's actually two these new broncos sports are weird with the fuse box. There's not just like fuses right there on the top because that's how I've always done it before I just buy an add a fuse from AutoZone for my power and then you can find a ground really easy with a voltmeter.

But basically I have to figure out one for the gauge itself inside the cabin and then you also have to have another power and ground in the engine bay because this is an electronic one so it has. I forgot to word the actual solenoid that reads the boost pressure in the engine bay so you can just run a wire to the gauge instead of running a vacuum line into the gauge inside the cab.

And I know all about how turbo's work and the trade-offs but this one is basically the same size and they just machined out the housings if I understand it right? And so it would still spin up real and still work good for regular driving and going off road things where you're in the lower rpms. Although you can get either an A/R size 0.72 or 0.92 AR, but I'd go with a smaller one because I want more down low power, not at the top of the RPM range.

However, again I have a lot of other stuff that I'm going to do first. I might not even do this. I just thought it was a cool thing and a lot cheaper than the other options that I knew about and it's supposed to be a direct bolton turbo.

Someone mentioned twin scroll. This one is not twin scroll if you look at the exhaust outlet picture, i the shape of it is more of a rectangle and if you look at like the 2.3 which is a twin skull it has more of a weird round shape I think I found a picture of the outlet showing it is a true single outlet but it really doesn't matter. It's not a twin scroll because for twin scroll to work it would have to have the dual exhaust outlets like on the mustang 2.3 and we only have a single outlet because the headers integrated into the head. So even if you put one on our car, it wouldn't give the benefit of a twin scroll.

I'm checking on the twin scroll as I was pointed out and 2015 it says they went to a twin school on the 2 l and from what I've seen of those turbos the outlet is shaped different where it connects to the head and this picture doesn't look like that. So I guess this probably won't work and that's why the broncos sports not listed. Although it is weird that it says it's good up to 2018 if they switch to a twin scroll in 2015, I don't know.

No blow off valves don't make power. Now on some of the older ones. People would upgrade the blow off valves because the stock ones were made of plastic and they weren't adjustable and supposedly the aftermarket ones were stronger and they had better diaphragms and better seals and so if you put on a bigger turbo or cranked up the boost it could handle it better.

But at least on the 2.0 in the broncosport and probably all the other ones from 21 and after if not earlier, our blow foff valves
are now controlled by an electronic solenoid and so it wouldn't work. Or if it did you'd have to get the computer retuned probably because the solenoid. Wouldn't do anything anymore. Now what you can do and like what I'm doing is you can buy a spacer. It's usually called a blow off valve adapter in the ads and it has little holes in it. So when you let off the gas and the blow valve solenoid opens it releases the air to atmosphere instead of recirculating it to the intake pipe and you get the cool woosh sound and that is all it does is give you the woosh sound.
And since our cars aren't using a maf sensor, it doesn't matter if you dump air out because it hasn't been metered yet. But if we had a maf sensor you'd have to make sure that it dumped it before the maf or you'd be dumping metered air and the engine would run rich cuz it would have less air than it thought it did but it seems like Ford's getting rid of mafs on almost all its cars.

It would be fun but yes these transmissions are slightly weaker So especially from a takeoff you'd want to be careful. Just smashing it to the floor but I actually drive fairly conservatively like right now my car says I'm averaging 27 miles a gallon.

There is a stronger version in some of the Lincolns but I think those have the V6 and I don't know if the mounting flange is the same, but I would only want a little more power because I'll eventually be putting bigger tires on it and I do want it to go a little faster but yes, even at the stock power levels it is plenty fast I just can't leave s*** alone.

I'd like it to be as fast as my 2014 escape. I had that thing doing 14 second flat quarter miles as best as I could tell. I never actually took the track so I don't know exactly, but I would like this to be able to do that with the bigger tires. I'm planning on getting a 1.75 inch lift I think the HRG although I think they said that 1.75 includes the lift that the Badlands comes with stock from the factory, so I think it's actually only 1.25 from their lift and they said that at the max you could fit 255/75 r17 tires and so I want to get that size in Goodyear duratracs which I find is one of the more aggressive tires you can get. That still works on a daily driver kind of and doesn't wear down super fast. Personally, I love the stock falcon ATW 3s and I think they're the best balance between off-road driving and daily driving. The KO2s are right up there too, but I found it. The ATW3s work a little better in the mud for me than the KO2s and I mostly deal with snow and mud

Also, it's probably going to be like 2 years before I get all this stuff done so y'all don't expect to see this stuff anytime soon. I want to get the catch. Can the boost gauge and the blow valve adapter on there before my trip to Yellowstone in May and from there we'll see.

The OEM turbocharger for the 2.0L was upgraded to a twin-scroll configuration in 2015.

 

[RSH]

You could try getting a tune and forego the turbo upgrade, depending on the level of tune you can get some good numbers out of the Ecoboost engines.
To me, making a hot rod Bronco Sport doesnt make sense, unless used as an AWD performance suv like the GMC Typhoon was back in the day.

 

[Bucko]

Interesting read to see that folks are asking/thinking about/doing upgrades to this already spunky 1.5 L engine.

For ne though, I'm leaving it just be. I already have a money pit car for that, in the way of a 67 Camaro.

When me and the wife bought the BS, she smiled and said to leave it alone!

Definitely interested in the follow-up with your mods.
255/75's will require trimming the pinch weld which I guess i wouldn't have a problem with.
I've been running 245/65 cooper discoverer at3's (a great tire) that have made me hydroplane and float on snow because of it being such a light vehicle.
I had the HRG 1.5 on an OB so now with the BL I'm probably getting the HRG 1.25 and they said they could sell me an extra plate in the front to level somewhat. I was thinking about 235/70's that wouldn't rub. But then I saw these. A good merge of AT and mud.
