4 adults also no problem.

Hi guys, I've just bought a Persona SV (AUTO) about 5 months ago. I found out the gearbox are so sucky and it consumes a lot of petrol. Go up genting 2nd gear also cannot, have to change to L, and it also make a lot of petrol consumption. I was planning to change the the engine and gearbox to GDI 1.8. But I was thinking that it was a new car and scared if the warranty will be cancelled if a do any modifications. Just wanna ask, when is the right time to change the engine, how long is the warranty from proton? As I know, if there is warranty, we still have to pay for any problems, so its better to just modify and its gonna cost the same. The engine now really not petrol saving and burning my wallet. Need your helps guys.. Thank you..

If you want to change engine this way, may as well get a wira cheap cheap and modify.

You no need be scared the warranty will be cancelled if change engine or gearbox, I reassure you most of the car major warranties will be gone. So no need worry since you get a definite answer now.

Hit an LCP (lighten crank pulley), be it the budget Works Engineering or the premium Mytheo. Plug and play item, if needed just ask mechanic to switch it out if claiming major engine warranty. My small SC did not even bother to see if its a mod, just claim only.

LCP will shorten the time when upshifting the gear while originally the stock gear box will initially hold it back for a while before shifting upwards.

That means it will switch the gear pretty fast and increase acceleration without car pulling the car back (PE got major tendency to do that). Thus without LCP, I won't even consider driving PE now

As for makan manyak petrol, 2 major points,

1. Your right leg. If you're one that like to tekan minyak, better go buy a viva to save FC, coz any car pun makan minyak if you don't change your driving style.

2. PE is a heavy car with an engine that has a weak lower torque. You got to live with it's makan minyak tendancies unless you go for lots of mid speed highway run. Either that or go change car to viva. You should have gotten a Myvi in that case.

For warranty, its generally for 2 years or 50K mileage whichever comes first. If you get dough and don't bother with warranty, then go ahead and switch the engine and gear box out..

However with the car weight and 1.8cc engine, I still think its gonna makan minyak. With increased power, your kaki will tekan more and more makan minyak. So how ar....

Thank you cavino for the info. By the way, about the FC, i'm using Putra with Gsr engine, and it consumes less petrol than my persona do. Thats why I'm wondering. I press on the gas pedal, and there is no pick up at all. So, have to press a little more to selit in when jam time, it consumes more petrol. I was thinking of changing the engine one shot.. I'm a traveler too, so its not comfortable to travel long journey in Myvi or Viva. I guess Persona is just fine. Any more suggestions??

Get the car supercharged / turbocharged? Honestly the time when I felt a need to limit the car to gear 2 or lower is when I reached close to the top of Genting. Before that it was pretty OK. Try turning off the air-cond if you haven't done it. That takes a lot of power from the car.

persona is not fine bcoz you previously drive a putra with gsr engine.
the power to weight ratio is much difference therefore ur putra give better fc.
another thing is the characteristics of campro. it is a high rev engine where the torque came late which means you need to rev high and as usual, higher rev, higher fuel consumption. if you ask me, with your current problem, yes, you will get better fc if you change ur engine and gearbox. but remember the car will not be as good as your putra because of the weight. if persona are made at nearly just 1000kg like those vios, city, almera, basically you will get fc as good as them too. however it is not really worth it if you just bought the car then throw in another 10k for the conversion. basically, the warranty that you really need to concern mostly are just the engine as gearbox where when they void ur warranty this two are very costly to repair which everyone are scared of. so if you actually plan to change the engine and gearbox, warranty is not a problem anymore. you might not even have to go back to proton anymore. just make sure you have a reliable workshop for routine maintenance that can make sure everything is working fine.

Coming from a previous car with a powerful engine to this pitiful powered car, sure you're going to regret left and right in terms of power and fc consumption.

I understand your frustration very well coz I curse left and right during jam and toll runs....

Try out LCP first. It would not even come near to matching your previous ride but it will "fixed" the lower end torque acceleration. I always get stuck in heavy traffic with an auto H-line. Frustration comes with all cars start jumping in front of you coz your acceleration is slow like a turtle. Tekan manyak manyak, makan FC and car surge in front a bit.

LCP remedy this issue to a satisfactory level. LCP used on a car with a strong low end torque like City is a waste coz don't see much difference but hit it on a weak low end torque engine with a reluctant gear box that does not want to switch upward when needed or downward when you want it....its a mod that PE auto tranny should not be without.

You might still not be satisfied based when compared with your previous ride but its a compromise.

I wanna change stock reflector to LED reflector, anyone know of any shop that is selling and also provide installation as well?

too bad now new honda can't buy this kind of car anymore.

can. not recommended if ur car is old. basically 40 give more protection. but used 30 before for sometime, it give better fc and acceleration in the city. but in prolonged highway run it actually gives noise? and it also have a bit more vibration.

Thank you so much bro. I can understand about the power to weight ratio. Its just i'm frustrated with the pick up thing. I will try to workout something else before going for it.

i will say decide on what you want before going for anything. if you mod here mod there at the end not satisfied, you will regret not go straight for the engine at the first place.
but then, somehow there are a lot of ways to improve the car.
since you seems to have the budget as you consider the engine conversion, maybe you can try something on engine management system. purely that is able to give you increase in power and torque while improving fc also.
can ask @ckdenion for that.

I see, you coming from putra 1.8. No wonder la you say persona cannot naik bukit one.

so i have to drive with 1st gear only or gear up to 2nd if possible?
good to hear that. my parents r doesnt allow me to drive with my old wira XD
around 4 adults with lots of luggage. my friend drove myvi and her car struggle to climb genting even though she only carry 1 adult
u done it before?

Since when a crank pulley has to do with gear ratio?

Ye ke? dei itu LCP pasang at engine crank, how lah to change gear ratio?

Dei wtf, gear ratio? LCP?

Cavino, your post gave me cancer. I died, then it resummoned me from the grave so that I can express my shock.

Not sure if trolling..

Persona FLX CVT

Just use D will do. If not enough power just full throtle the paddle. Dont scare with the engine roaring. It will automatically shift to lower gear if you need more torque. D,3,2,L is all about shift lock, not gear. 3,2,L is usefull when you go downhill and want to use engine braking, if you select L, the gear will remain lock on 1st gear only. If you select 3, the highest gear will be 3rd gear and it will not shift to 4th gear. no need to depend on brake only, use the shift lock when downhill.

good to hear tat his post makes you back alive... instead,that post makes a few sifus come bac alive...

Oops....read back....wonder why I use the word gear ratio...what I meant is the gear tends to switch in earlier rather than pull back the car engine.

Today I read back also I feel very embarrassed. Don't know why I post abt gear ratio pulak...

I'm going to hide my head under a bantal now...with my jiken...

Reminded me never to simply post rubbish technical explanation, will get shot down by sifus....
