Variable air intake doesn't help reduce FC that much as seen in some earlier generation Conti, US & Koreans made when they have not able to develop proper VVT in early 2000s. Toyota SC got greedy and set short interval to cheat owners? People don't change ATF fluid that short interval for conventional AT, at least 100,000km onwards only.

Saga FLX
Engine 1332cc with VIS but no VVT
output 94ps@5750rpm
torque 120Nm@4000rpm
kerb weight - 1055kg lo-spec / 1065kg hi-spec
CVT gearbox
0-100km/h 14.5s

Fiesta 1.6 AT
Engine 1596cc dual VVT + VIS
output 122ps@6300rpm
torque 152Nm@4050rpm (website showing 148Nm ??)
kerb weight 1153kg hatchback / 1171kg sedan
6AT - strong & bigger gears 3.917 1st gear
0-100km/h forgot whether 9.9s or 9.7s

Saga relies on smaller engine & lighter weight for FC. Saga FC can't even beat Myvi 1.3VVT. How sure are you that Saga can beat Fiesta in city FC? Fiesta is 1 of the few B-segment (budget <100k) so far that could challenge Vios in real city driving. Preve Campro VVT is belt driven which is less effective like older generation Korean made when they first came up with VVT, all belt driven. Only Sonata NF Theta engine & later i30/Forte Gamma engine equipped with timing chain have proper FC comparable to Toyota.

You think Toyota so kind and generous to give timing chain? FYI, timing chain cost more expensive to produce and that chain alone cause Toyota to lose out millions out of 60k timing belt replacement income. They have no choice but to give timing chain as the VVT could only operate well with timing chain.

Toyota is known as reliable & durable, some uncle doesn't even bother to change ATF and their old Toyota gearbox still in 1 piece. FYI, conventional gearbox is mechanical and the ATF fluid is there to serve as lubricant. CVT gearbox ATF not only as lubricant but to allow the movable face to operate well. 

CVT is made as more gears alternative when they could not produce 5AT with larger gears at that time. Today, gearbox manufacturers have no problem coming up with 6AT, 7AT and the latest 10AT gearbox with much larger gears than the Manual transmission counterpart.

Probably your self made turbocharged engine have to service everything early as the air intake & exhaust part pressure doesn't comply and inefficient choking the engine. Breath in too much air and can't fart out the air well causing excessive pressure trapped inside and more carbon buildup. Have to clean everything often therefore your maintenance cost go skyrocket.

There is no joke here, only you and those who could not accept reality and facts said so to prevent the knowledge from spreading. It's an unethical strategy called make facts look like made up with you bunch outnumbering that comment.

Ohhhh timing chain improve FC!

Seriously im interested in the part too much air goes in cannot come out ... Lol lol lol

MAN He is Good in these stuff man!!
. Pressure build up cannot release I bet gone case d... Lolz.. But he can build a system where pressure can be trap ! KReS in turbo

Warranty cover is not so big issue..
Like the most expansive parts on gearbox?
4AT can last longer than CVT after pass 5 yrs who guarranty it?

In the first place, once you bought the use car, if that car is purely accident free..
So why you too worried?

For example on my 2003 sentra and clocks over 150k Mileage already.

What I did.. Change the engine oil, 4AT oil, suspension that so... Still can last another 10 yrs.

Make sure you do interval 5k Km for serving & maintenance, what is the faulty parts and change on next serving.

These car also like human, didn't take bath and sleep or change cloths, even new born baby also will faulty.

i just heard from my colleague that ATF is changed every 100k
he might got the information from this fella....
if one going to drive the car 20k km per year the ATF going to last him 5 years
for me i have no confident that the ATF remain unchange in my GB for 5 years

for me i going to change it around 30-40k interval

Sure or not?
From I know, 4AT Gb in recond set only cost less than 5k all in, if really unlucky.

How bout new saga SV CVT?
Over 10k right? If after warranty or unlucky.

If you have own more than 10 yrs old ride until now, you sure appreciated of old car vs new car today.

For me I am to be the hobby as sentra N16 now.

Like a member of the inspira gang whom use to own and fd3s.. now driving er34 with rb26dett. Keep poison me get my dream ride fd3s.. i told him even i can buy cash .. the car will be my daily cash wash and polishing model.. lolzzz

ofcoz like you said earlier better
but when i go to see my "under-tree" ah beng workshop at 20k interval gear oil change he said i siao that y i change it at 30k
wah people owned ER34 also interest with PRC smell

rx8 also same bro?

yup .. he told me that .. infact he did have a spare 13B in his store when he got his ride .. lolz ...
and my inspira is on his rx7 ori allu wheels ...

its just a crappy satria 
i bought it a very cheap price about 13k for 2005 auto last year
going to change it to manual auto is fucuking serow

this is still 1 of my dream car.but looking at the cost of maintenance, i can say this car is not for me  but now i see at mudah got many ppl selling off this car around 80k-90k. wonder why.

Second hand car higher interests and no promotions too.

Fiesta is 1 of the few B-segment (budget <100k) so far that could challenge Vios in real city driving.

Only Sonata NF Theta engine & later i30/Forte Gamma engine equipped with timing chain have proper FC comparable to Toyota.

If your car has VVT, example if it is Camry 2.0G '09.
1998cc with 1st generation VVT (low to mid end support only)
output 147ps@6000rpm
torque 190Nm@4000rpm
kerb weight 1450kg
city FC - 8.8km/L

If you had the intake VVT actuator removed and tune it to same tuning as above, the Camry will have the FC deteriorated to just 6-7km/L for tuning to that high plus with that weight. FYI, without VVT, the 2.0L could only tune to between 176-180Nm to get 9km/L with kerb weight of 1370kg. With 1450kg even tuned to 180Nm would experience serious underpowered and end up fuel guzzling as you need to rev harder. You think VVT for what? It's not just a name.

2nd generation full time VVT intake only could get hi-rev capability. With dual VVT, they could save FC, go hi-rev and even tune up higher to 165ps which is impossible without additional support or risk engine blown.

nightstalker1993 <- wannabe spotted

Gouki Are correct...
even i noobs and newbies at FnF sections.... and
who say oldies GTR R34 and Subaru can't remapping the ECU?
just u spend a bit at ECU and some "piggy" and etc etc etc
then can runs like a boss, u cannot mah... rite?

inb4 learning to mods the cars..

and stop bullshiting your UN-KNOWLEDGED STUFF!  
read your post..... gonna come outside and slap u
