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 gear ratio means it will switch the gear pretty fast and increase acceleration without car original gear ratio 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....
