- Here's an off the cuff talk about my X47 upgrade...includes thoughts on reasoning, parts needed, hardware, cost, install, sound, mpg, driveability, power. Note this is on 93 pump gas, check my channel for an upcoming review on Race gas concentrate. This tune wasn't dyno'd but on pump gas with X47 these cars make around 270whp/295wtq. My Race Gas concentrate tune dyno'd at 298/323, more on that later....
Wasn't shooting for quality here, just a quick phone video.
If you're here just to see the acceleration then go to:
3:40 for a 3rd gear pull
7:40 for a 1st-2nd gear pull
12:40 for a 2nd gear pull
Hardware list:
X47 turbo tuned by Adam at Tune+
Tune+ wastegate actuator
Cobb FMIC, catted downpipe, Accessport
Mountune catback exhaust
Velossatech big mouth intake
CP-E cold air intake
Go Fast Bits DV+
Ported exhaust manifold (custom)
NGK 6510 plugs (one step colder)

The last 3 items are the ones you’ll need one or the other - either the studs/nuts or the bolts. My car needed the bolts. There are 9 manifold studs/nuts, I got only 6 as I figured all 9 wouldn't break. None did. But I got 6 for insurance.
If you have questions leave a comment and I'll get back to you when I'm able. Thanks for watching.

Installed my x47 in October, completely changes the character of the car. Very enjoyable! Good luck with it!
Thanks saying how much you spent and the costs involved with this. I appreciate that as I have been trying to figure out how much a Turbo upgrade would be all in and was figuring about 5K for everything.
Thanks for the information
Sure thing. You can do it for under $3k if you get used stuff and/or lower end TBE/FMIC.
It depends on what you consider fast these cars aren't fast in a straight line but I know darn well they'll outrun most of these boats on a windy road
Drove V6 Accords while looking at the Fiesta ST. Also drove a V6 Q50, and a V6 TLX. They are all technically faster, but I honestly didn't notice as it was all very top end and basically only showed up near the middle of an on ramp. In terms of drivability nothing came close. I could afford "more car", and the FiST was far and away the better drivers car.
I can see getting the FMIC and a few other things, maybe a downpipe, but I'm genuinely worried about making the car worse as it's so well set up already.
If you're keeping stock turbo get a FMIC and a panel filter and a Cobb Accessport and a custom tune, that's right at $1000 and it will transform the car completely. Best money to spend if you're staying on stock turbo. Downpipe is a waste of money, you'll gain unuseable low end power while you'll lose top end power which is not good, trust me I've researched this for 5 years.
I've driven 6 speed MT Accords and other such cars, yes they're faster than a stock turbo FiST but the car feels boring in every way comparatively. Really most cars do...GTi, Golf R, V6 this or that, Audi S3...I've driven a bunch of these cars and can't wait to get back in my Fiesta, those cars may be quicker and nicer inside but have no personality after owning a Fiesta ST.
Make it video worthy.... and your channel will be the best FiST channel out there. Your knowledge is nice for everyone.
Yeah my "production" sucks. Not interested in anything fancy though, I'm just taking videos with my phone and publishing them no editing/etc. But thanks for the backhanded compliment.
Great honest review for a change
That's the goal, and I'm trying to help people understand that this isn't necessarily the best upgrade for everyone.
Thank you! Someone without a new owner bias. This is the problem i run into with my cbr1000rr, why have all the power if you cant use it? Sticking with my e30 stage 3 for now thanks man looks like a really high cost to do it right
You're welcome. Yeah everyone puts money into their car and thinks it's faster than a Bugatti. I'm here to say it like it is. Really you can get the power I have for under $3,000. I think I talk about the cost in a different video. Anyhow enjoy your ST.
Very nice review mate!
Great video! I've seen your name on the forums many times while clicking around. Thanks for dropping all your knowledge=). Is rev hang inevitable on this car? I did buy Mountune FB1 a few weeks ago, installed the AP3 with the OTS Stage 1 Tune about a week ago, and rev hang is still there. I saw on forums prior to buying the AP3 that the tune would help with rev hang. I was sadly disappointed =(.
Thank you sir. Yeah rev hang is the thing.......might be able to tune it out but I'm so used to it I don't care much.
This engine has a heavier crank and flyheel. I got a lighter flywheel and it seems to have reduced rev hang some, but it will be difficult due to the rotating mass.
Do you think the X47R is the better choice now? I don't want the X57, too much power for what I an purposing the car for ..(haha yeah, who says I don't want too much power?) but I'm curious about your thoughts since this video was posted a while back before the R came out I think.
They don't make the X47 any more, only the R. You can find them for sale on rare occasions though, backstock or used. The R spools later and has more power later but the turbo lag isn't my preference. Still it's a great turbo. If I were shopping again and the X47 wasn't available I'd consider an R or a Whoosh turbo. Yeah I agree X57 is too much plus I still haven't seen much on them so I'm not even sure there are any cars with that one on it yet.
gray25xt makes sense. Whoosh is second on my list... possibly a S280 but I know that is a laggier higher end turbo as well.
@@ryeguy88I'm not sold on the Whoosh, I've heard good things but I also see some red flags and some inconsistencies in date. The X57 would be a good option but they're so expensive.
gray25xt most likely 47R if it sticks around otherwise it looks like the standard 57 is a good option and doesn’t demand majors changers to the basic bolt on set up
Nice video, helps me to make a decision if want to go this route. As the power has increased did you also upgrade your engine mounts? Just wondered if you had experienced any engine knock
Thanks Badger. There are three mounts, one low down, one to the right of the engine and one to the left. I replaced the lower mount with a Cobb mount early on. Recently I added a Powerflex mount insert to the right mount. Soon I plan to order and install another insert to the left mount. I've examined my mounts and they are in great shape, though I have heard of others with around the same power levels as I have with torn mounts. So I think the earlier they are replaced once the power upgrades are done, the better. Some folks are replacing them with solid mounts but that's too much added NVH for me.
What do you think about your exhaust with the catted downpipe and the X47? I am starting to contemplate hardware to support a hybrid turbo setup and then there is the great debate about exhaust ID and whether bigger pipes help the turbo spool. I know you have a Mountune and it is actually a very nice CBE that is not offensive. Someone else commented on his Borla which is 2.25" and there is conjecture that this is too small. I remember discussing this in my VW gti days when APR had 3" turboback for their stage III and the consensus was that 3" was great for top end and there was some bottom end loss. For me 2 1/2" was always perfect, no more no less.
Jim Haight Truth is a wider exhaust might bring 5 hp but for me this was the perfect balance between sound, power and flow. I will always keep my catalytic converter, the smell without it is too much and makes the sunroof no fun. I’m not an expert but my hunch is that because of the housing size of the turbo I am using, a larger exhaust would make no difference. But with a true big turbo set up a larger exhaust would probably help but only a little.
Jim Haight also I agree, increasing flow or diameter of various exhaust pieces can help and hurt at the same time. There is tons of evidence about this car that a catless downpipe, for example, helps on the bottom end but hurts top end power. Not a sacrifice I would want to make.
I have a full bolt on with an E30 Panda Motorworks tune and I've kept up with Hemi Challengers no problem.. Yet you state that this can't keep up with a mini-van 😕
You are incorrect, I was talking about the stock turbo not keeping up with a minivan, not my car. A V6 Honda Odyssey minivan (I have one) will do 0-60 in 6.6 seconds; a Fiesta ST does it in 6.9 and that's with a brutal clutch dump. 3rd gear roll, stock ST does 50-70 in 6.9, Odyssey in 4.1. An ST with bolt-ons and E30 tune will get closer to the 4.1 figure, but is would still be neck and neck.
Assuming your E30 with Panda tune is stock turbo, there is simply no way you will keep up with a Hemi Challenger. Even if you had a big turbo, it's still not possible. A Fiesta ST with full bolt-ons, custom tune and E30 might do 0-60 in 6 seconds flat with the right driver and a clutch dump. Maybe. A Hemi Challenger does it in 4.2 seconds. The only way you would "keep up" would be if the Hemi driver couldn't drive. Or it is possible that you "kept up" from 30-50mph at which time the Hemi would leave the Fiesta far behind; there's no way an ST on stock turbo can keep up with a V8 approaching triple digit speeds, it is simply not possible, even with E30 and a tune and all the bolt-ons, not possible.
If you don't believe me, go find a flat road, set your Accessport to measure your 0-60 time, and post your results. Folks with the same setup as you are getting in the low 6s but that's it, I've been in the ST community for 2 years and have seen this conversation over and over. Let's say you got a 6.4; in that case, you barely kept up with a stock mini-van, maybe besting it to 60 by one whole foot.
I love my ST and did full bolt-ons and custom tuning on the stock turbo before going hybrid, but let's be realistic. Too many ST drivers out there think their car is the fastest one on the road. The Fiesta ST has tons of torque but on the stock turbo, in any configuration, it still feels way faster than it really is.
Invalid by no means; the car has 6 gears, downshift to 3rd or even 4th at 50mph and you'll get the turbo to spool no problem, that's why we have the wonderful manual transmission. 2500rpm-ish can be found at any speed under around 70mph, you just have to pick the right gear.
Not sure what you're talking about here, nobody got anything handed to them, you're describing a stock turbo, this video is about a hybrid X47 turbo which thrives after 5,500rpms, but thanks for stopping by Chillis2u.
Chillis2u that wasn't me, learn to read, that was Nathan Rock who is on stock turbo. I was explaining to him that the car on stock turbo was quick not fast and comparing performance numbers to a minivan.
My car in question here is a Fiesta ST with the X47 upgrade. It makes 100hp more than the car on stock turbo. It makes 80hp more than the car on stock turbo with all upgrades plus ethanol tune. Either way it's a huge difference.
gray25xt I think he meant the r/t 5.7 hemi, not the scat pack 6.4 hemi. The 2018 5.7 only have 370 hp at the crank and weigh 4270 lbs. The Fiesta with e30 (dizzy tune get 230 like mine) at the wheels, so I think it's possible to run neck and neck or beat it, from a roll of course. I'll assume that the Fiesta, in my case, has 260 at the crank while only weigh 2700 lbs.
What size did you go with on the Federal RSR's? I don't see them in the stock 205/40r17 size but maybe I'm missing something.
215/40/17
Did you mention if you're sticking with the stock clutch & flywheel? I thought the extra torque might be catching up with the drivetrain?
I am staying stock they hold till 375ish I"m nowhere near that.
What size you running the rsrr? And on stock wheels? You should do a review on them
Stock wheels, I like them. They are Federal RS-R, not the -RR. The -R has a wet traction rating and is ideal for daily driving, whereas the -RR has no wet traction rating and are better for track only IMHO. I'm +1 sized, 595 RS-R 215/40/17 tires. I thought about a review one day, maybe sometime....in short, the good is they stick like crazy, they are super cheap. The bad, a bit of tire noise (though not really too bad at all, just more than other tires), they have no treadlife so I might be replacing before too long. But they really do stick way better than the stock Bridgestones, both in cornering and in acceleration (more traction which is why I bought these).
Is the fiesta st a 1.5L?? Cause I have a 1.5ecoboots fusion and I’m looking to see what aftermarket turbos fits the 1.5 engine?
1.6 us spec 2015.
"Car is too slow, need more power"
*Makes it have more power*
"It's undrivable, it's too fast"
Right on Cole, right on.
The idea here was to have the power on tap if needed, but the reality is that it's more power than you can really use on the street safely.
Hey how did u like those federal Rsr tires? We’re they louder then the stock tires? I might get those too for my fiesta.
They are great, very sticky. People swear by them at the track. On the street, a bit of noise but nothing bothersome, you get used to it after a day. They are cheap but the question is how long will they last. I bought them knowing they had no treadlife rating....we will see......
I also went with these tires after the factory ones wore out. I have 5k miles and love them so far. I drive hard and they don't let me down. It just got cold here. Today is was 34F and it still was gripping hard. They are better than factory and cheaper.
Quick question. Do you get any turbo flutter type sound when driving 10 to 40 mph.. changing gearss. Cheers
Sometimes in cold weather but it's barely there and only sometimes. I'm pretty sure it's the wastegate and it's normal. Your tuner can fix that issue with a tune, my early tune revisions had a good bit of flutter but after my tune was finalized it was gone, I hardly ever hear it and only when it's very cold outside.
gray25xt thanks for this. I have x47r and a dfb recirc valve.. but driving around low speed.. lots of flutter... cheers
Stuart Prescott i’m trying to get a way to get that flutter
I think most folks in the fiesta community don’t understand “lag” you want a fast fiesta? get a bigger turbo. I’m getting a s280 with only downpipe, intercooler and panel filter. All that’s needed..280-300whp is the sweet spot for this car.
The forums are full of you guys having no idea what you’re talking about. 26-29psi at 2-3500 rpm is a good way to break transmissions ,bend rods etc. once you’re rolling why would “lag” ever matter. You trolls are just obsessed with 2nd,3rd gear rolls.
Once you’re in boost a turbo doesn’t come out while under acceleration.
So dragging or road racing or spirited driving bigger turbo. You wanna go fast at 2000rpm in 3rd gear while passing cars downtown or autocross ?hybrid.
0-60 after mods?
Come to think of it I've never used my Accessport to record 0-60 since the turbo swap, when the weather is a bit nicer I'll make an effort to do that and make a video about it. Stock the car is about 6.8; with bolt-ons and tune on stock turbo it's around 6.3; I've seen folks with my current setup or similar post numbers around 5.3, so let's go with that. Somewhere between 5.0-5.5 I'd say realistically with a good launch. The thing that slows these cars down is the rev limiter kicks in in 2nd gear at 58 mph so an upshift is required to get to 60, which slows things down. My redline is set a bit higher though so I should get to 60 in 2nd gear.
gray25xt I was able to get to 60 on second gear by raising the Rev to 6600 on e30 tune.
How would you compare this hybrid turbo with the Mountune MRX? They both seem somewhat similar.
Jim Haight I actually have a friend who has the MRX and we were not able to compare in real life but we compared data logs extensively. Bottom line is they produce relatively similar dyno numbers and acceleration numbers on the same fuel. The difference is the MRX spools a good bit later so the power kicks in later but holds a bit longer. The X 47 spools quicker so it will take off earlier but does not have as much top end power as the MRX. Theoretically in a road race the X 47 would pull ahead and then the MRX would catch up around 60 or 70 mph.
I guess when it comes down to it, maybe the MRX might be easier on the launch and the top end? But this is way down the road for me. Just in the "information gathering" stage at this time. First mod on the car is obvious and clear since, my lack of a firmer motor mount on my Gti caused the braiding to come apart on a new down pipe. Therefore I have learned a lesson.
In my opinion you're getting stress on the components of the car regardless of when the stress is put on the engine/transmission. Yes launch will be easier in the MRX since there's less torque down low but it's still stressing the mounts and the rest of the car. I suppose a lot of it has to so with how you treat the clutch. You can get a decent launch and still be nice to the clutch. I researched the MRX myself but I do not like it because it is quite laggy and changes the nature/character of the car by moving the power band. I bought the ST because I love the low end torque, I don't want to lose that. With a hybrid in this case X47 you keep stock driving characteristics (low end torque) but maintain power till redline.
Check out this link, this is a V-dyno comparison between my car and my buddy's MRX, you can see how the torque/power band is shifted to the right:

Literally dont need intake till 400+ whp range
E Sondi agreed
I had money to burn...did it for fun. It probably adds 2 hp but it looks sweet.
Do you have an upgraded RMM as well?
Yes I have the Cobb RMM. Really helps firm up the shift feel and also I've had no issues with the motor hitting the firewall as some report on the stock RMM.
