What? auto? That's blasphemy!Thought he's getting an auto transmission
Bro. Pomen leh! He got Forester turbo, I think auto Myvi for wife, and a spare rally spec car.....lolThought he's getting an auto transmission
Thought he mentioned 1jz vvti. Didn't know there were manuals for thoseWhat? auto? That's blasphemy!
Reminds me of that Citroen AX at Nurburgring.I guess thats the same Myvi that overtook my brother in a manual Neo CPS. That driver really knows the road as he position his car nicely for each corner.
Standing on the jack how many years already hahaha.
Myvi always the street legend...move aside r35...smdhMy 2 cents.
- Since this is a shared car between you and someone else, don't bother modding for power. Make the car handle better with a set of good aftermarket suspension, a lightweight set of rims, a good set of tyres, lightweight larger brake calipers and rotors, sound proofing and better headlights would make the car nicer to drive and possibly even easier to drive.
- Don't add a ton of UR bars too, understand what each bar does and only decide which bars you need and install those only. Adding everything will stiffen everything and that may not translate into a better drive.
- Exhaust mods at this point is pointless. If you do big mods with your engine then change exhaust to match, sure. Do nothing and just change exhaust - waste money. Stock is good enough la. 4-2-1 or 4-1 won't make financial sense, it's not like your car currently is slow. Vios' in general have great pickup and have great FC. They just don't handle well most of the time.
- Changing to a large TB will have some downsides. If you're unlucky you'll get "on/off" throttle. In my own experience with Myvis, the 2nd gen has a larger TB than the 1st gen and I have both. Swapped the two around and the response was sliiiiiiiiiiiiiiiightly better on the 1st gen Myvi. Not significant. The 2nd gen one has larger valves and all - so if I swapped the head then I'd have better performance. But I wasn't going to do that on a pointless minor performance upgrade. The head gaskets cost more than the performance gained.
Like I said - the Vios is a great performing car. It's not gonna beat any land speed records or outrun a R35, but it's not a slouch and drives pretty well. With a good set of suspension, brakes and rims+tyres, you'd have a pretty nice car to drive around in. Learn to drive the car fast bro without the performance mods. I know a guy who drives his Myvi 1.5 STOCK (except for 15" rims + good tyres) faster than a lot of people going up Genting. In fact he's so fast people driving way more powerful cars have claimed he has a modded car until they see his tiny little exhaust pipe and stock engine bay.
Hi, for a 1.5 NA to gain power is a difficult task and expensive, time consuming if you DIY like I do. If you just bolt on parts it's not going to work, For NA engines to see improvement is to make it more efficient and improvement on air flow in and out. Most you hear why people who bolt on bigger throttle body say it's not worth it because they are doing it wrong. The TB is just part of the intake system, if you want to upgrade you need to upgrade and improve the entire system, from the air filter box to to the intake manifold to the intake cylinder head, same goes for the exhaust side. When you've improved the air flow in and out, you need to look at ignition and fueling system and AF ratio across the rev range. modding NA is complicated and a lot of head cracking time, sleepless nights and lots of disappointment.Hi guys, new member here, as a rookie to modification world, wanna ask is that any way to upgrade your car performance without turbo or supercharger modifications?
(cuz the maintaince and cost too much lol)
Besides, one of my friend recommd me to change the 1.8 throttle body, but there are others of my friend say it is not worth, any idea?
Last but not least, my car is 1st generation vios 06 year model (ncp42)
true. same as motorcycles.Hi, for a 1.5 NA to gain power is a difficult task and expensive, time consuming if you DIY like I do.

Suspension mods chassis mods and all other, I will not talk much, it depends on what you want the car to be and for what purpose. if modding without a target or purpose it's pointless.
I have a 1.3L NA saga FLX only..less CC than you...hahahaha
Interesting. I wanna comment on a few things here purely because I wanna ask or because I've had experience contrary to what you listed.Hi Liang95,
Honestly speaking, Vios by stock itself is quite lively, it can keep up to some bigger CC car due to its light weight body. It was never made for highway speed monster. Like most ZTH citizens here recommended, try to make the car handles better and more stable than stock. What you can do:
1. Not technically "sticky", but better grip. Putting overly aggressive tyres may end up hurting his somewhat stock car. I recall a time I had 4 AD07 tyres on my super stock Myvi 1.3 auto. My god did it affect performance but I could corner like a demi-god.Handling Part
1.) Stickier tyres
2.) Lighter rims, more responsive steering wheel, however you might feel lightness in your steering wheel on highway speed
3.) Uprated struts and springs, if not, BC Racing V1 or BR Type if you have budget
4. This is debatable. I'd install some for the safety aspect but after having tried bar-ing up my whole ex-Wira I've realized that the bars add unnecessary weight. Maybe a good ARB, potentially a strut bar and maybe a fender bar will help a Vios but anything more than that would be added weight imho.4.) Install necessary chassis bars, research this properly, you don't want to waste money on those bars you do not need, car needs certain roll to be able to change direction
5. Agreed. But not any old foam. There's two major players in the market that actually work. All others are a complete waste of money and time. I've tried 3 different types of foam brands and I can safely say the cheapest ones that claim the world are pointless.5.) Chassis foam, for better sound proofing and sturdier chassis. Ever wonder why Euro cars are so solid and quiet ? Sturdier chassis and undercarriage is one of those keys. It also adds comfort to reduce NVH. You feel you can drive the car for as long as it could.
6.) Harder engine mount, reduce engine flex and get the car going off the line faster. May cause discomfort as you feel more engine vibrations
7.) Better brakes ! Seriously a lot of people thought the factory brakes system is enough, it is NOT ! At least uprate the disc rotor, brake pad, brake hose and DOT4 brake fluid.
8. A free flowing airfilterEngine Part
8.) Uprated intake system, only helps the car to breath easier but won't gives you 10+ hp like some ads claimed. Especially on a 1.5L N/A engine
9.) Free flowing exhaust, this one depends, but for me, just decat one of it will do. You won't want noisy exhaust in your DD.
10.) E-throttle controller, this can dramatically change the pedal responsiveness but will not add HP
11. Those spark enhancers have potential side-effects. Vios uses COP right? Why not just buy better COP and modify them to fit instead? And make sure the grounding and voltage from the battery/alternator is smooth and consistent.11.) Better spark plugs and ignition system, most likely the most obvious power gains for any N/A cars, if you have access to TM Works ignition package, this will be the most obvious power gains you ever invested, however, ITS NOT AFFORDABLE !
12.) Larger TB with larger intake pipe. Adds throttle responsiveness and gain power at mid to high RPM. Not usable if you don't rev the crap out of the engine to get its full benefits.
13. I know shit about this.13.) Aftermarket VVTI Valve, enable VVTI opening at lower RPM (Not VTEC like but under normal driving you feel the engine is lighter)
14.) ECU remap, another obvious power gains but need to find someone that really knows how to tune.
Hi Liang95,
Honestly speaking, Vios by stock itself is quite lively, it can keep up to some bigger CC car due to its light weight body. It was never made for highway speed monster. Like most ZTH citizens here recommended, try to make the car handles better and more stable than stock. What you can do:
BEST MOD, BEST ROI EVER, 5/5!Handling Part
1.) Stickier tyres
SECOND BEST MOD, STYLE TOO! ROI depends on how much you spend. Don't buy VOLKS lah, too expensive. ROI 4/5 to 1/5 depending on how much you pay.2.) Lighter rims, more responsive steering wheel, however you might feel lightness in your steering wheel on highway speed
Done right 4/5, done wrong 0/5. The most common problem is that its "low" for better handling, lower center of gravity. If you determine how low you should go by the looks and not the suspension geometry, most likely its done wrong.3.) Uprated struts and springs, if not, BC Racing V1 or BR Type if you have budget
5/5 when done correctly. The most obvious one is the strut tower bar. And anti-roll bar. Unlike tyres this one don't wear out. Worthwhile but don't go overkill with ALL sorts of bars.4.) Install necessary chassis bars, research this properly, you don't want to waste money on those bars you do not need, car needs certain roll to be able to change direction
Doing this aftermarket, the impact really isn't that great. I've done it, at the most famous and pioneer of foaming. 1/5 for me.5.) Chassis foam, for better sound proofing and sturdier chassis. Ever wonder why Euro cars are so solid and quiet ? Sturdier chassis and undercarriage is one of those keys. It also adds comfort to reduce NVH. You feel you can drive the car for as long as it could.
Haha you'll regret it for a street car. For the ROI and pain, 1/5 for a street car.6.) Harder engine mount, reduce engine flex and get the car going off the line faster. May cause discomfort as you feel more engine vibrations
Better brake pads, ss braided hose and of course the DOT4 brake fluid (make sure its fresh sealed bottle). 5/5 if you choose good brake pads. Brake rotors of the same size for street driving is 0/5. Brakes stop the car by turning it into heat. More mass can contain more heat. So unless you change to the big brake kit with bigger rotor... changing just the rotor won't make a difference.7.) Better brakes ! Seriously a lot of people thought the factory brakes system is enough, it is NOT ! At least uprate the disc rotor, brake pad, brake hose and DOT4 brake fluid.
If just dropping in aftermarket air filter, just pick K&N. Washable and reusable. 2/5Engine Part
8.) Uprated intake system, only helps the car to breath easier but won't gives you 10+ hp like some ads claimed. Especially on a 1.5L N/A engine
This is the MOST SIGNIFICANT MOD, in terms of, awareness. You will be VERY AWARE of this mod. ROI on a naturally aspirated car? -2/5 for street driving. 2/5 for track driving.9.) Free flowing exhaust, this one depends, but for me, just decat one of it will do. You won't want noisy exhaust in your DD.
No comment on this. It's just a "feel" thing. I don't pay for feel. I pay for real absolute gains.10.) E-throttle controller, this can dramatically change the pedal responsiveness but will not add HP
Changing to Denso or NGK iridium spark plugs, now most cars come with it anyway. 5/5. Ignition system, ROI 1/5. Very costly, I think spending the money on exhaust and full intake more noticeable in terms of noise and style. 2% on a car with 100hp is 2hp. 2% on an evo with 300 hp is 6hp.... Does TM Works got gains? Got, confirm got. Question is, you pay the same price as the evo owner.. you gain way less.11.) Better spark plugs and ignition system, most likely the most obvious power gains for any N/A cars, if you have access to TM Works ignition package, this will be the most obvious power gains you ever invested, however, ITS NOT AFFORDABLE !
Might mess up your ECU tuning, if the intake of air is out of the range for the stock ECU. Actually even more significant is the intake ports itself are larger. I changed from a YRV head to a Myvi 1.3L lagi best head because the ports and the corresponding valves are physically bigger. No tuning definitely messed things up. ROI is 0/5 for no tuning, 2/5 with tuning on N/A car, 3/5 on a turbo car.12.) Larger TB with larger intake pipe. Adds throttle responsiveness and gain power at mid to high RPM. Not usable if you don't rev the crap out of the engine to get its full benefits.
Tak tau.13.) Aftermarket VVTI Valve, enable VVTI opening at lower RPM (Not VTEC like but under normal driving you feel the engine is lighter)
Vios can't remap, will need piggybacks like E-Manage. Not much use unless changes have been done to the intake or exhaust. Problem is 9/10 don't know how to tune. ROI? 0/5.. you find someone who knows how to tune.. with no mods.. 1/5 maybe. with mods.. on N/A.. 2/5..turbo.. tuning.. 5/5 because increase boost yo!14.) ECU remap, another obvious power gains but need to find someone that really knows how to tune.
Correct.What i suggest, the handling part for now is the best thing you can do, as one once said, power is useless without control. It's 1.5L N/A engine
Hi Izso, which are the 2 foam manufacturers which worked for you?.
5. Agreed. But not any old foam. There's two major players in the market that actually work. All others are a complete waste of money and time. I've tried 3 different types of foam brands and I can safely say the cheapest ones that claim the world are pointless.
6. Don't do nylon or full rubber mounts. A compliant PU mount from superpro would be way better than solid mounts. Less harsh.
