Really enjoying this series of wheeler dealers, could never get away with the American version
So glad to see Marc's mechanical prowess on display! Impressive!
Ahhhhh ha ha ha ha ha ha ha ha ha ha ha ha .........ha ha ha ha ha ha ..... what a load of dog eggs
@@barrydavies998 how was it when you were a mechanic on a winning F1 team?
Oh, wait…
@@barrydavies998 waiting for your apology

Marc is an excellent mechanic and a fantastic personality behind the camera! Well done Michael for making such a good point!!! 👏🏼
Had 1 of these engines in a bravo hgt 2.0 5 cylinder was the only 2.0 that was affordable to insure back in the day had a lovely sound to it aswell, sold it to my friend who then took it to a indicated 141mph. What the actual top speed was I don't know but was nice sporty car and unusual for a 19 year old at that time.
Probably 139mph if it showed 141mph. But yes 5 cylinders are the perfect unicorn engine, turbo or na, they ooze character and uniqueness. Personally i think the 2.0 sound better than the higher capacity 5 cylinder engines because of the smaller cylinder bores and with that comes the cheaper 2 litre road tax bracket. Tho going turbo 5 cyl i could NEVER go non turbo. Simply because the sound is all the more intoxicating xD
@@cylturbskie yep the tax bracket and insurance was crazy low for a 2.0 then, couldn't insure anything other car above a 1.6 but the hgt was same price as I was paying on a clio only paid admin fee to change over.
@@beany1987 yeh thats what i do mate, just the fee to swap the car over, tho this time i got a refund swapping from my 2009 520d to this 340 wheel horsepower fiat coupe 20vt plus model. The 2 litre tax bracket has gone up its now 295 quid to tax for the year as opposed to when i got my first 20vt 8 years ago and was 220 for the year.
@@beany1987 speaking of insurance i went from an mg zr 1.4 105bhp at the cost of 800 pounds fully comp to my first fiat coupe 20vt with 220bhp at the lower cost of 541. This was when i was 23. Like what were they thinking! xD
@@beany1987 it was like they were paying me to try n kill myself? Lol
They forgot about the IC, the std one cant cope with that boost, you get over 60deg C into the plenum. Apart from ca 25deg air and no pinking, you’d get 10-15hp more, with a front center mounted intercooler.
Then, that exhaust manifold will crack, its shit. Try get a new or repaired OEM iron, and port-match it (they’re s little off on cyl 4 & 5 usually).
There will be a little torque steer, so do get a lower subframe brace, OMP for Alfa 155 on ebay. Will reduce it 95%
Your right there mate, the standard smic cant cope for shit, certainly when they get full up of oil overtime from the breather system vapours pooling up in the piping.
i have the pro alloy big fmic on mine. unfortunately causing the car to run abit hotter at idle and on boost (am heavily modded) but ill be putting the 40mm aluminium radiator on and deleting the ac condenser and putting a fresh thermostat on mine in a month or two.
@@cylturbskie That sounds like a different issue, the FMIC shouldn't cause any heat issues. Mine didn't (but then I was only at 340bhp, not 5-600 as some others). If it runs hot on idle I suspect the fuelling is thin side, or the radiator is shot.. The new one will tell that, I suppose. Good luck! Fantastic cars these.
@@pereldh5741 i read on some old forum post that a couple more people had the same issue after fitting the fmic running a few degrees hotter with both the ac condenser and IC restricting air flow, i have a new alloy 40mm rad to be fitted along with a new thermostat which will be going on in the next month or two, but as soon as it has air flow going through and not on boost the temp drops right down to 65-70 degrees if not a we bit lower depending what speed im doing
@@pereldh5741 i cant keep up with the comments im starting to put the same thing twice! what a pleb am i😏
Looking forward to this new series, looks like an interesting line up of cars.
This Fiat Coupé is the same as mine! But I upgraded the brakes and changed the shock absorbers with the addition of a new anti-roll bar before moving on to upgrade the engine!
I am amazed with the turbo's workshop and its machine. Fantastic!!
Before you should even think about winding up the boost on an old turbocharged car, you should do a compression test on each cylinder.
And change oil 😅
Bye!
Beautiful review, and beautiful specimen! .. 👍🏻
I would like to add and talk about a detail that has not been mentioned in the video review at all, that is the traction, as it is considered (the 20V Turbo) one of the best front traction in the world, due to some technical details not just, that is :
THE FRAME: "Type 2", this is the evolution of that of the Lancia Delta, more rigid and robust, as well as the body.
THE TRANSMISSION: A sophisticated (especially for the 90's era) electronically controlled transmission through turbocharging management (Garrett TB28) invented by Fiat / Bosch, on the first two "EBL" (Electtronic Boost Limiter) gears, of this what few are aware of, even if it has been mentioned several times by various Italian magazines such as: Auto del 1997, Quattroruote 1999, and also by international magazines, as well as a mechanical self-locking device called (ViscoDrive).
I think it is right to say a few words about the sophisticated electronic control of the transmission on the traction, and on its operation.
There are 2 sensors / switches inside the gearbox, which are connected to a first satellite control unit, this is connected to the mother control unit (Bosch Motronic 1.1.2) which in turn is connected to a second satellite control unit which is connected to an electronic valve called "Pierburg" which always in turn controls the WestGate valve of the Turbo, opening and closing it according to the wheel spin by means of the ABS sensors.
The beauty of this sophisticated electronic system lies in the fact that it does not INTERRUPT the wheel spin, like a common "ETC" (Electtronic Traction Control), where it cuts the current to the engine, making you feel the classic serration and kickback, but REDUCES the wheel spin. of the wheels, precisely decreasing the supercharging pressure, so as to maintain a fluidity and pleasure of driving while driving, without losing performance.
The system automatically excludes itself once the third gear has been engaged, included onwards, to reactivate automatically once returned to 2nd and 1st gear respectively.
The control system, if necessary, can be excluded with special "Computer Examiner", and not by the Driver in the passenger compartment.
The beauty of this sophisticated system lies in the fact that if you want to elaborate the Coupé, even in an extreme way, to increase power and torque, and therefore performance in general, with more extreme trim, etc .... With this electronic system (with ECU reprogramming) you can choose the boost pressure according to the gear engaged so as to always have a smooth and pleasant drive, without excessive skidding and loss of control of the car!
ES: If original, the pressure expressed by the Turbo is: 1st gear 0.8Bar, 2nd gear 1.0Bar, from 3rd gear included 1.2Bar (therefore the maximum boost pressure).
By carrying out the processing you can do:
E.g. 1st gear 1.0Bar, 2nd gear 1.2, Bar, 3rd gear included onwards 1.5 / 1.8 / 2.2, and beyond, so as to never have the classic explosion of power with relative wheel spin in the first 2 gears, which takes away the pleasure of driving.
A truly brilliant and unique system in the 90s sports!
We remind you that the "normal" Fiat Coupé 20V Turbo and special editions (Limited Edition, [numbered and certified] Plus Edition, and MY99 'Edition) is the only 90' front-wheel drive sports car to have a controlled transmission and mixed management, (Electronics + Mechanics), the latter cohesive in unison, in the name of mimesis, although these are not physically connected to each other in a single piece, like a classic "VDC."
In practice, the mechanical self-locking (ViscoDrive) acts as a "TC" (Torque transfer) and the "EBL" (Electtronic Boost Limiter) electronics as a skid control.
SORRY IF IT'S LITTLE !!!!!
*******
P.s: Some models (more than a few) of original "Limited Edition", new, and of a single owner, rolled on the test bench, have all registered powers of over 230hp, in spite of the 220 declared by Fiat.
This indisputably explains the greater performance in terms of maximum speed and acceleration scored by the various magazines, in spite of the "normal" 5-speed versions, that is: (252.23 Km / h, LE, against 248Km / h Normal .), and acceleration, (6.1 / 3 Sec.LE, against 6.5 Sec.Normal) all electronically "limited" in the first 2 steps, as stated above.

Bye!
Elvis has left the building
Celtic Tuning, only the best. Nice to see them involved with this project.
They have remapped two over my cars in last four years and both were fantastic results and value. Very recommended!
Amazing work on the turbo.
And its back. This is the real Wheeler Dealers....
elvis i personally think your the best mech yet mate
Very good episode. Car is one of my favourites and i really liked the color. There is one problem though, avoid using that "cheap' cooling fix with water injection. In theory and practice it works but the downside you add water droplets into your cylinders which in turns scraps your manifold and whole exhaust as a result of corrosion.
Fantastic car. I owned a Sprint blue 20v turbo with tan leather 20 years ago. Such a well built car. I would have another. Just missed out on one that was up on ebay last week. Same spec, sprint blue with AC, sunroof and tan leather.
Hmmm, I'd have opted for putting in an oil filter relocation kit with an oil cooler and an oil-air separator kit as well. It'd allow for greater power gains while increasing reliability and making servicing a tiny bit easier.
And if, at some time, you buy and do one up for a profit, you can do that. But this is not your project now is it.
Dont forget these guys only do the absolute bare minimum in terms of preventative and needed maintenance in order to actually make money.
Personally i just vent the breathers to atmosphere on my 6 speed plus. Barely any room for another damn container of sorts under the bonnet unless you have an fmic and put it in the corner where the smic used to be, or do something reducing the size of the washer bottle to allow more room there.
@@cylturbskie I get, it's just a personal thing. I tend not to buy cars that don't at least have an oil filter relocation kit cause it's a pain in the ass to replace the oil filters on the vast majority of cars without one. Even when I do purchase one, it's among the first things I actually do after the initial service. Pretty much every car I've ever bought, sold or traded has had it either done before or done by me. Save for maybe like 3 Mercedes.
@@Dominik189 oh yes i know what you mean dude, the coupe has one of it not THE WORST damn oil filter location ive EVER seen. Only thing that really puts me off is the relocation kit vibrating loose over time like filter sandwhich plates tend to do, i have a paddle clutch and get enough vibrations pulling away as it is,
On the coupe the oil filter is basically sat behind and between the aux belt that is driving the PAS + alternator and the turbo down pipe so if it decided to squirt oil everywhere its going straight onto the turbos hot side :/
Damn Mike. You need to lay off the pies! 😂❤
LMAO 🤣
Why
@@user-mi4yc7pr3x Watch S1 of WD and compare his appearance to the current series and you will get your answer....
@@saads7 he's getting older?
@@user-mi4yc7pr3x Yeah well done mate. Genius! You hit the nail on the head 🤦🏽♂️
This is a 20+ yr old classic by now. Keep it stock and take care of it. Boy racers go somewhere else.
Is Wheeler Dealers stiill active? It’s been a long time since I’ve seen a video from you.
The whole episode used to be on here a short while back in english but they took it down.
Here a 12sec fiat coupe owner which have modified by himself:
The turbo shaft play should NOT be checked like that, but from compressor to turbine and viceversa, along the shaft;
Turbo hybrid like that which you described is a KILLER of engine, because generate huge backpressure, usually exhaust mainfold pressure will be HIGHER than boost in intake mainfold. That tb turbocharger is ALREADY a factory hybrid, so she have anyway pretty much a big compressor wheel and small turbine. If you would install even BIGGER COMPRESSOR WHEEL keeping same turbine wheel, is like you would try to inhale on mouth and exhale at same flow in same amount of time on your nose. Which is IMPOSSIBLE. Not to memntion the waaaay greater temperature on exhaust which makes gasses to exoand even more.
No part 2 to this?
Definitely one for my collection when I win the lottery I can’t afford to play regularly.
There is no way that turbo was running in that car with that much play… you must have hammered that poor thing to get it to move like that 😂😂😂
I feel like he really undersold how absolutely destroyed it is
@@Sheehy223 absolutely 😂 that thing spins up to 100,000 rpm and it would send itself out of the housing
calm down mate it wasn't that funny
Please do a Fiat Uno Turbo or a Punto GT Turbo
like Elvis
wow! 317 HP and more of 300lbs/ft torque, the best episode since ed China left the show (for me)
Its on borrowed time imo, that standard intercooler will heat soak like crazy after a few pulls and be way down on power.
I say on borrowed time because of no supporting mods for that power level.
Mine is running 340bhp to the wheels. And 303lbs/ft torque. It will eat this for breakfast, brunch, lunch, dinner and desert.
@@cylturbskie🤷🏻♂️😴
What about the extra cooling of the intercooler 😃?
the Italians do like an inaccessible engine bay 😂
This car was designed with the 4 cylinder twin cam engine.
This model has a 5 cylinder, ofcourse its tight lol what did you expect.
It's like an Audi S6 V10, tight af engine bay.
@@aaryeshg.6526 genius.
it's an Alfa disease. Their packaging has always been to support exterior design, with maintenance at the bottom of the priority list. Makes most of them a PITA to work on.
Mike we love the new format
It's the best wheeler dealers
Of all time, love elvis 👌
If the manifold is the steel one, it will not survive for long, I have seen several break, including mine... Better to go with the original one, but it has to be reworked a bit
Good to see Mike and elvis back in the UK
Truly. Super Glad he’s back. He’s Good Bloke
I love the fiat coupè 5 cylinder turbo
When can we see the new shows in the US?
I hope they replaced the standard plastic recirc valve or atleast checked it. Because they will die and leak with age and heat. It may be leaking and overworking the turbo maybe only a psi or 2 (and they may not of even noticed) but after time it can hurt the turbo. Aswell as the plastic end tanks on the smic leak also again with age and heat, tho they are not as bad as some of the other standard SMIC from other manufacturers.
Having to partially pull out the engine to change the timing belt and the water pump sounds ridiculous, especially on a Fiat...
The car was originally made for the 4 cylinder FIAT Twincam. The 5 cylinder was a tight fit.
You don't have to pull it out at all...
That’s what she said.
@@neutronalchemist3241 the Fiat 16 Valve too the space is Very tight
no need to pull it out, just needs to be put into service mode
Got a question about the all-purpose cleaner (allesreiniger in dutch), what brand did you use, and does it work with all plastic types? (I have Golf mk4 from 2002 with the same problem)
And what brand plastic restorer did you use afterwards?
Thanks in advance!
When is this show on I can't find it
It's on Discovery plus mate .

So where is the follow up video ??
Grande auto
Well, of course there is editing. Separate turbo from iron exhaust. Look at shiny header. And, wait for turbo overhaul.
This guy does nt actually work on the cars - he is way too clean lol. You could see that Ed was greasy and got his hands dirty but this dude is more like a face of the show
Where to get parts for water cooling radiator?
5:20 didn't knew Mark had a second job as a mechanic.
Alex from car trottle got a soft spot for these cars
Mike, you seem much more chilled these days and that’s a good thing. Take it Easy ❤️ Welcome Home 🏠
Damn I used to think they were sweet back in the day there a rare right on the roads now
In my country 20v very Hard to found
Since when does increased power increase the strain on the timing belt!?
its the writers of the script, they just say what they are told to to make it sound worse than it is, the writers clearly dont know the difference between crank and wheel horsepower which the presenters clearly know but it just gives more evidence that the show is scripted
It doesn't. I think the script writers need to make scheduled maintenance more exciting.
Boa tarde congrats vai amém bom trabalho
Seth Rogen makes turbos! Nice
Oops it jonah hill
Big turbo big enjoy
Ciao belli
Damn mike, hope your health is ok.
Dit is zo geen reëel beeld van hoe snel dit allemaal gaat.
We created a 400bhp fiat coupe.
Now ant is gone, what?
Mike made a pass at him!
Fiat!!!🔥🔥🔥🇮🇹🇮🇹🇮🇹
Could someone please tell me if that guy used to work in F1 cos they never mentioned it🤣🤣
Magyar felirat lehetne előre is köszi.
Did he say the turbo spins at well over 100,000rpm?
In the test rig
@@nowtelsematters he gives the impression they do that a lot though.
@Lloyde Turner it was the way he said it, it implied they operate that fast usually...rather than when on test. I think the F1 cars can spin at 200,000rpm but I'm not sure ordinary cars go much past 70 or so
@@sleepingwarrior4618 shows how little you know then. Go look at a compressor map, compressor speed can exceed 100k fairly easily.
@@nemanja162 can.....that is no way normal.
he does know the water pump he fitted is not metal doesn't he 🤦♂️
They probably recorded that scene before finding out they couldn’t get a metal impeller. 😂
720p, really?

Ol mate doesn’t pass up the chance to mention how he use to work of Formula1 cars.
Great cars , nightmare to work on .
Depends on what you do… Clutch & cambelt, yeah! :)
They keep changing the mechanic on this show when they should just get rid of mike.
Seriously? He feels the need to use a 20 inch long ratchet to remove sparkplug? Over compensation for something?
better than smacking your knuckles
like for only Elvis
Listen Mike it's all finished when Ed was gone.
Ed chinaaaaaa
pas de fin avec la ferrari !!!!!!!!!!!

Trying to look like a 575 Ferrari.
Ahhhhh ha ha ha ha ha ha ha ha ha ha ha ha .........ha ha ha ha ha ha ..... what a load of dog eggs
6 ho gaye he 30 karva 🙏do plz
Hes not the mechanic
This is one of my favorite cars, so sad to see such a cool design outside and such a poor design for its core; I mean, cast iron manifold? Come on... (Still managed to make 252 kph though)
Most factory turbo cars have iron manifolds, even the most famous ones. The iron manifolds held the heat of the exhaust gas better, which reduces the underhood temperatures. Had cars like the Nissan 300ZXTT not had iron manifolds, the problem of underhood temperatures would have gone from bad to even worse. Those cars are difficult enough as is.
Wow my ex nightmare.
WD is that bad now it's advertised as fat boy brewer and a Trusted mechanic how they ruined a good show is criminal
Did you guys put the dodgy MOT on this car or did the guy your bought ir from do it? Look up it's MOT history people 🤣 This car is a shed.
I can't wait to see what figures it makes on a really dyno also. 309bhp and over 340lbs/ft? Nah.
Is it me or has this program gone soo dog 🐕 s**t since Ed left…..
It is definitely you.
No Edd, no care
Sry didnt watch this show anymore. Edd China was the best.
One of the ugliest little cars ever
You will never see an Italian, French or English car parked in my driveway.
Even my loved manufacturer, Volvo, is no longer what is was.
Since Ford bought Volvo in 1999, all successive Volvo's were really a Ford.
A 2009 Volvo V70 is really a Ford Mondeo on false plates.
I stick with my V70T2/2007 and my S60T2/2005 until a reasonable replacement can be found.
I do not pay Volvo prices and receive a Ford!
