Seriously I'm speechless with all the negativity that surrounds when someone posts asking about bolting on turbo onto their car. Is it that bad? Maybe TS is serious about it and he just needs a point to start. Everybody have to start from somewhere.
1. many shops can do, depends on who you know
2. custom setup where got name bro, you think like japanese car can buy bolt on Greddy kit ka? That one also will cost you 5 figures
3. It's called a turbo KIT for a reason, there's definitely many things that needs to be installed.

1. Not really as long as done right the first time. Maybe just change the oil more often(instead of 7k, change at 5k)
2. depends on your foot. how much fuel you use depends on how much power you use from the engine. if you kaki binary keep boosting then your FC definitely will go down but if you just drive normal, your FC should remain the same or even better than stock.
3. 5k onwards to 5 figures depending on setup.
your concept about cars and how turbocharger system works is totally wrong. Technical experts you can refer to others who had already done it(as can be seen, there ARE turbo'd Forte's running around already), research online what others did overseas, research around BOT users from other cars as well.

- As mentioned previously, FC depends totally on your foot. You take a Golf GTi 2.0 and whack all out touge in genting and watch your fuel burnnnnn
- Usually overheating is not much of a problem, the problem about boosting high boost is whether your engine internals can take it or not. Pistons, conrods, crankshafts etc which is why you see people swapping out their pistons/conrods/crankshafts/gaskets with something stronger if they really go serious into their turbo setup. Intake manifold crack? HAHAHAHAHAHHA!! Exhaust manifold crack ada lah which is either due to shoddy welding during the fabrication of the manifold or your exhaust temps(tuning) is way too high which your pistons will melt first before your manifold will start cracking. And usually people engine blow is due to the head gasket giving way, pistons cracking, conrods or crankshaft snapping, but definitely not manifolds cracking.
- Air intake pipe cannot be straight? You gotta be kidding me. Explain why people go for ITB(Individual Throttle Bodies) then. It's basically sucking air direct from the atmosphere, no bends and whatnot. heres a video with ITB and standoff injectors.

- A properly done up car can actually get a higher RV than a normal car as long as it's properly done up. If you want you can even remove the kit and demod the car and the car will be as good as stock, plus you can earn back a few grand from selling your turbo kit.
- you know alot of technical jargons like wastegate, twin scroll and VGT but seems like you have zero clue on what those are or even means. All petrol cars running turbos requires a wastegate, be it internal or external. VGT, twin scroll are technologies which improves turbo response and performance. Since all turbo's have wastegates, do explain the relationship between wastegate and turbo lag then and also i'm curious about carbon buildup if i release throttle at the 2000rpm spectrum.

I agree that newer cars comes with new technologies that reduces turbo lag and improves performance but things that comes out from the factory isn't exactly the best. They're designed so that they can be massed produced cheaply and effectively while still able to do it's basic job, albeit not the best. Many forced induction cars(4g93T GSR engine and Preve S4PH-T are good examples) have rubber hoses as their intercooler piping which expands under boost and this expansions robs about 500rpm before full boost comes in which is why many people replace it with stainless steel versions and Samco elbow bends which won't expand under boost. Stock exhaust manifolds are also cast iron. Swapping it out with a custom-made tuned-length 'banana' manifold will increase performance as it enhances exhaust gas flow to the turbo providing faster spool-up. Long story short, not all things that comes out from the factory, designed by 'engineers' are good, there's always space for improvement.
Agree with this statement, i suggest TS to study on how turbo system works first and all the parts needed, at least it will save you face by preventing you asking stupid questions to veterans who knows their shit.
the Forte in the video is an auto and the auto GB robs alot of HP from the car. A Polo TSi may win it, but hey, it's still faster than most NA cars on the road and can easily tapao a Vios.

My 2c to TS is to do your own research and what you do is totally up to you as it's your car anyway. But before you do anyhting, make sure you have enough knowledge on hand and don't regret whatever you have done(unless you've done something really really stupid) As you can see, many of the people here in this forum are just keyboard warriors who knows jackshit about the technical aspects on cars. Long gone is the time where this forum used to discuss technical stuff like cams and engine design, now it's just a place where people compare cars and ask what car to buy with a certain budget.

long post, bye bye

edit: btw, please do NOT get your kit from Xenon. just google up their name and you'll know what i mean.

Since TS asking for advises whether to get Turbo, you are the devil while I am the angel. Ofcourse, 1 support 1 against. Those custom shops you mentioned, do they even know anything about pressure and air density in the first place? Do they know how to calculate the most optimum flow? Those piping are done with proper measurement or just copy and think got the style means ok. You can set air intake straight but it will not draw the highest volume of air with optimum density before pump into engine. You could draw lots of air but not highest density end up more fuel guzzling.

Excuse me, Forte 2.0 NA will get better FC than turbocharged 2.0L. This is fact. Also, the FC depends on how high the boost. If boosted to 2.4L engine strength professionally by Kia, it'll consume less fuel than 2.4L NA but still higher than 2.0L NA.

When comes to hands of Ah Chong or Ah Meng modify workshop, Lol!! Whatever they do, they are nothing close to what real carmakers could do in reality. Only end up with high FC and more horsepower but less torque. Vios is not made for performance and it is nothing more than a city car. Why take that for comparison?

Do you know what are the function of VGT & Twinscroll Turbochargers in the first place? Ever since these 2 types are introduced, those normal turbo we all know are now labelled as lower level wastegate turbocharger to differentiate clearly from the 2 new toys. What do you know about turbolag?

Pug508 1.6T
output 156ps@6000rpm
torque 240Nm@1400rpm

The turbo activates from 1400rpm onwards. If you think below 1400rpm without turbo assist is lag, that is wrong. Turbolag happens when the turbocharger activated and while operating at 3200rpm and there's sudden deceleration, the pressure from exhaust become low and to allow the turbocharger to continue spinning optimum, the VGT would retract the blades for low pressure mode continue to draw in air.  Twinscroll type in BMW has 2 vents, 1 for low pressure and that allows the turbine to keep spinning under similar situation. The older normal wastegate type can't do this.

Talking about maintenance & reliability, do you know those who knows nothing about pressure would end up choking the engine. In long run, wear & tear faster and more often, requiring more cleaning.

Honestly I'm pretty lazy to reply this as this clearly shows your lack in technical knowledge. But since it is already 5am in the wee hours and I need to waste some energy in order for me to sleep, here's my post.

What you need to know about pressure and density? Ideal Gas Law? Boyle's Law? Charle's Law? Seriously? And talking about intake, you say straight air intake won't draw in as much air as a 'bent' air intake? Those 4age's 1600cc are pushing more than 200hp with that setup and you're telling me it's not drawing enough air? Let's go to Jet engines then, direct ram air intake. Anything to say about that? It's still basically a 4 'process' engine as it still requires intake, compression, combustion and exhaust, just that it does it all at once. Air is sucked in direct from the atmosphere and it makes use of the ram effect at high speeds and altitudes.

You're saying the efficiency of a 2.0 NA will always be better than a Turbocharged 1.6L with the same power as a 2.0NA. Seems like you're missing the knowledge about volumetric efficiency here. Turbocharged cars will always be more efficient than NA engines as the turbocharger is harnessing energy from the exhaust which on an NA engine will be wasted, then using that energy and compressing air, forcing air into the cylinders, increasing it's volumetric efficiency. About FC, as long as you drive in vacuum during normal town drive your FC will remain the same or even better than when NA, and will definitely be better than one with a higher cubic capacity.

Reason we're comparing with a Vios is because the Vios is basically in the same category as a Forte, a basic everyday-drive point A-B car. If a Vios can be turbocharged, why not a Forte?

Yes I do know the function of a twin scroll and VGT, I'm just afraid that you don't. Seriously you're making a fool out of yourself saying 'wastegate-type' turbochargers are old school tech. ALL turbochargers used in petrol engines needs a wastegate else the boost level will just climb as the RPM increase until the engine kills itself from overboosting.

The way you're describing 'turbo lag' is as if you're describing a supercharger. Activates and deactivates? Bro, a turbocharger spins even when the engine is idling. When a turbocharger starts producing usable boost is a whole different thing, it doesn't 'activates' and 'deactivates'. Newer technologies can start producing usable boost at an earlier RPM than older turbo's with older technologies and hold that boost throughout a longer RPM range than an old-school turbo, but the way you describe it is totally wrong. What vents for low pressure and high pressure? All VGT does is changes the A/R ratio and exhaust flow in order to compensate for low-rpm and high-rpm driving thus creating boost at a lower RPM and then changing the nozzle angle to accomodate higher RPM operations. Some VGT Turbo's in Diesel applications do not require a wastegate as they don't rev that high anyways and does not produce that much gas flow but most petrol engines do. Volvo's VGT turbo's does have a wastegate built-in and a twin-scroll turbo definitely have a wastegate built in. They're taking technologies that had been long used in the aviation industry in jet engines and finally putting it to use in the automotive world.

For those who don't know what's VGT, HERE'S a simple description on what VGT is. For twin scroll, it divides the cylinder exhaust gas, thus seperating exhaust gas pulsations and improves the scavenging effect in a 4-stroke multi-cylinder engine. And yes there are also split to a small and large turbine for lower and higher engine rpm efficiency.

About your last paragraph, so basically a bolted-on turbo engine will die because it would choke the engine, eventhough with a turbo you're basically forcing air in? What a joke. I do agree that the wear and tear in a turbo engine would be slightly higher than an NA engine but with proper maintenance, both NA and turbo engines will last pretty damn long. What cleaning in specific are you talking about? Throttle body cleaning? top overhaul? Engine bay cleaning(LOL)?

Before you comment any further, do share what car are you driving and what car had you driven? Plus what had you modded on your car(or any cars) in that aspect? I see you have an atrocious reputation in AutoWorld forum i see

Anyways, good night.

I doubt you know what pressure means and what purpose it serves in combustion engine. You don't know anything don't go and influence others to install turbo without consideration. You'll end up causing him killing the engine early and also causing him dearly should FC goes too high and his car lost resale value. Having wiring messed up could hardly get proper wireman to fix. Most of them can't fix, just to keep the electrical part barely functioning.

Yes, I owned and also maintained proper turbocharged engines and they come together with the SUVs, pickup trucks and cars. They were well made by Engineers that work for R&D in the respective brands, Ford, Hyundai, MMC, Toyota, Pug, etc.

Definitely not any Ah Beng with trial and error background that mod car like they think look like Need For Speed Underground or Fast & Furious means very good. They don't even know what pressure is. All they do, quote you custom ECU + intercooler + self made steel piping with style (not proper pressure calculation), normal wastegate turbocharger (prone to much lag), and have the diagnostic like machine to tell how much to boost. That's all. Nothing else, just tune according to how much the customer wanted. Then change large noisy & polluting exhaust. Final artwork, a car that would need to rev harder to move. Low end torque failed one.

LoLzz

Yoyr frens from thailand or not??


Sorry bro cant help it..

His crapping is until a level I dun even wan to read. Lolz

I dont read what he type at all, all crap   

HOLIDAY HOLIDAY 

Lyn f&f constantly have pro appear like k5master n now another...  Entertaining....

Whatever workshops they open, I have zero confidence on their workmanship, etc. Got degree but lack the machines & tools to do the precision calculation and most importantly, the material required to make proper intake hose will not be able to come up with anything close to carmakers tech & precision.

You are the fool here, stop trapping people with sweet talk that they could tune up their cars without worries. 1 wrong move and that spells the end of his car. Stop using the word 'Beh Tahan". Go to toilet then.

Lolzzz...

We became salesman .. So did u bro.. Turbo salesman

sleepwalker <--- macam ini:


or, use the report post button

HAHAHAHAHAHAHAHAHAHA

shit's getting so stupid, i don't bother replying already.

I'm currently taking my license in Aircraft Maintenance Engineering and air flow is basically what i NEED to know, and I've been running a bolted on turbo Waja for more than a year now and i can easily tapao any Vios or Forte on the road. Talk so much, what qualifications do YOU have to give all these advice? Gouki have a degree in engineering, ketam here tunes ships and gensets for a living and what about you?

If manufacturer's tools and machines are SOOOOOO accurate, why are Proton's so shoddily built eventhough they have the tech for a turbocharged engine right in their back yard? Why do manufacturers use cast iron 'inaccurate' manifold instead of tuned-length manifolds? Surely they had calculated that with a log-style cast iron manifold, the exhaust flow surely wouldn't be optimum since the pulses will clash with each other before reaching the turbine no? SURELY with their PRECISION CALCULATIONS they would've known the hoses they use to route the charged air from the turbo to the intercooler and to the throttle body will expand under boost and cause around 500rpm of turbo lag, why did they do that? Does it mean that the manufacturers had calculated turbo lag is actually good for the car?

Stop making a fool out of yourself. I may be a decade younger than you in real life, but your tech knowledge and attitude is of that a dacade younger than me.

was your degree from Thailand?
No? not valid  

I'm reading this and I can't ban somebody for being wrong without him making any offenses in forum. You guys have not learnt from years of being in the forum that there will be attention seekers with wrong info. Some you can incite him/her into replying with hatred in which we can ban them. Some will play the game safely and we will have no reason to ban them.

This forum does not have a function to remove a certain person from the topic by the topic starter. What we can enforce from here is for you guys to police your own topic. If a certain person is interfering in your topic and upon the request of the topic starter, I can warn that person not to reply and then if he still does, then I will have a reason to ban as he has ignored the warning.

If the topic starter can't be bothered to do so, I will assume that the topic no longer holds interest for him/her and I will close it the moment I get reports of members stirring up issues.

So the next time you see a member stirring up issues, please PM the TS to take action and report. I will do the appropriate.

No. Ignore craps and attention seeker will go away. Reply with craps would just be taking the bait. Just get the topic owner to report that their topic is being disturbed and I will remove the replies. Next reply would earn a warning and the next will get a holiday from the forum. If there is no response from the topic owner, I will close the topic since it no longer holds the attention of the owner. That is playing by the rules.

Hey guys, I am finding all this really interesting. Didn't know it would last this long and generate into a turbo discussion thread.

No, I have not gone invisible, I have been reading through.

But I urge you fellas to maintain the peace and civility - if you disagree, just agree to disagree. This thread has generate so much knowledge for me and other guys here. I just don't want it to turn into a warzone.

To sleepwalker: This can be a legendary thread? Wow, I am honored.

So how? Want me to close thread or let thread wither?

Sell off your forte i would suggest if you still love your life. I and my cousin already sold off our kia 6at version.
Full of problem.. Really regretted bought this car. My cousin almost flew out from windscreen lucky got safety belt protecting him. His car airbag didnt deployed when involved in accident with a toyota vios. His car front side all gone , leg stucked inside and steering on his body.. Cant imagine how kia designed forte actually. My forte, since bought, the car dashboard full of noise, complaint at SC but still persist.. Then before reached 10k milleage, engine keep dying. One morning suddenly cant start up, towed back to SC, after a month only collect my car. Using less than 20k, engine cant start up again! Really lousy car, i and my cousin really regret bought this korean car.. Should follow parent advise go for japanese cars.. My father toyota camry also never had this problem.. 2008 until now.. About 6 years already. Hope my SA faster deliver my honda city.. Really tired because of this lousy car.. Traded in to used car dealer only worth RM41k.. Used 1 year + only... Biggest regret..

good that you are monitering.
i wonder why material science is a basic subject in all engineering courses. 

owh, i think is because IT IS A BASIC in engineering degree!

bro, havent you tell us your qualification? because everything you said, i can find it in the book of foolgineering

malas reply liao.

I think, usually manufacturers' original setting is more pessimistic to cover the reliability in very harsh condition (tested in dessert or antarctic area), that some people got the ecu re-mapped to get better fuel consumption (maybe ignition timing earlier/air-fuel ratio to lean,... ), what ever car it is. Maybe some tuner is crap, but it should not be all.
