I see you are/were an anime lover and a geek. Previously I was a geek too, I can repair and have repaired speakers, laptops, desktops upgrade software, and trade small small electronic stuff for a penny.

So I will be gentle a bit in reply-ing you.

Since I am already working full time, have a professional career and also have to handle my shop business as well, I can't always spend time to research and diy everything myself even though it is my passion/hobby. As a diy-er, you should know much time is needed (researching before DIY as well), especially on cars that needs specialized jig and some handy equipment to do proper repairs. Example like my audio upgrades, their have an equipment to make sure that all wires are connected to the correct phase or not it will sound weird. I do not really know what is that or how to use it, nor do I have the equipment. To know all that and do a proper job, I will have to spend a lot of time for research and testing. Finally I will have to fork out money to buy the equipment. Normal people don't have this equipment nor will the shop rent it to me as they also want to do business.
Get it?

Mechanic say every time you do an oil change. I say every 10k should be ok, base on my visual inspection lol.

thick dust already wor.. clean better haha

vvl also kick in la. exactly same as vtec the concept, switch cam profiles to more aggressive profile at 5500 rpm. Just the mechanism different.

Do you have a car?

oriat

Yes honda engines have more aggressive profiles, but they lack torque for the b series.
k series should have big improvements since b series is a 10 years later tech than the k series haha.

Assuming you love spirited driving, what is your budget? Because it gonna cause you more than 10k for the conversion. Get ready 13k to be safe.

My car not antique la . Mine is a beater car. Gonna use it for the occasional spirited driving and going to work.
I saved a lot when I use my another old beater car previously, compared to my friends who use new cars. A LOT. Compared to them, I saved over 20k in the course of few years, including all my repair bills! And because I maintained my car nice nice, my car never break down in the middle of the road too.

Aiyo same goes to new car la.
My friend one year car already have unstable idle rpm which until now toyota SC says it normal because they can't solve it, weird squeaky sound here and there which took a few trips to the SC to solve.
I also have one friend new 1 week old car broke down while driving and need to tow away.
Sure new cars are less likely to break down, but it is more to the owner's issue. if you properly maintained and inspect your car, it will be as reliable as a new car. Furthermore old car's has less electronics which are more likely to fail.

In short, since I knows about car maintenance and did not skip those important ones, I can say the big advantages newer car has are SAFETY during collision and Second is fuel consumption.

Giant hypermarket during promotion period. Bought 4 bottles lol

If you are referring to the amount i spent on my car, you haven't seen anything. I have seen guys who spend 5k on paint alone for his honda civic ferio (25 years old car). And he used up all his savings lol. Me, my allocated budget for my car is only a small portion of my available cash in my savings. Savings that i can spend if i wanted to. Heck i can buy a new car in cash if i wanted.

Yup

I am aware. The safety ratings is very poor for this car for current standard. 0 stars lol

Beli at lazada, pasang at ub mart at penang

7k without repaint? Can list down what things u done?

Its from giant. Should be real

My car inside still looks relatively new due to proper care. Old volvo u need wait few months to get parts.

I did changed car just recently, to this car lol. Its my project car, built for daily ride too.
