Stock Iswara 1.5i Aeroback
Automatic Tranmission
170 km/h
6200 RPM

Pretty impossible for a stock Iswara 1.3 manual (even with meagre power help from the slightly enlarged exhaust) unless at a steep downhill or the faulty speedometer is faulty.

I'm driving a stock Iswara 1.5i auto myself & I had also driven a stock Iswara 1.3 manual before too. Unless it is modded, moving downhill or speedometer faulty, no way to achieve 180 km/h.

Then it is definitely the speedometer is faulty or out of calibration. Even the specifications brochure for Iswara 1.3 manual did not state its maximum speed can achieve 180 km/h. It is not the matter believing you or not, it is practically impossible for a stock Iswara 1.3 manual to achieve that speed.

I had practically driven almost all version of stock Iswara 1.3 manual, none can reach 180 km/h. However, I experienced driving an Iswara Limited Edition 1.3 manual with a slightly faulty speedometer (the meter moves up & down a little) able to achieve the top speed of 175 km/h (that's considering the speedometer is faulty). I had also heard from other forums that claimed stock Iswara 1.3 manual can achieve over the max 180 km/h on meter but the drivers themselves believe the speedometer is faulty.

Tried both brand new & used unit before, not possible. My current 6 years old Iswara 1.5i auto can achieve 170 km/h though.

The problem is that we are talking about 180 km/h, not 170 km/h.

No offense, but definitely not possible for a stock Iswara 1.3 manual. All people that I know of (from real life to forums) who achieved that figure also acknowledge that the speedometer is faulty.

If you had driven many Iswara cars like myself, you will know how frequent you will encounter a faulty speedometer (especially those going up & down, +-5 km/h) on Iswara cars.

Please don't get work up. It is a fact that stock Iswara 1.3 manual cannot achieve 180 km/h in reality. If still don't believe, ask your friends/relatives (with actual technical & cars knowledge) or even google. If still not convinced, try to ask your friends/relatives to try out top speed together, so you can get benchmark results. I trust your posted picture is real but as I said before, your speedometer is faulty or out of calibration.

My current stock Iswara is 1.5i (pre-installed fuel injection kit by Proton, only available to limited units in the year 2000) automatic but is for sure 170 km/h is achievable and the speed verified with my friend driving a Waja following behind.

Regarding the brochure, I'm not sure about it but car manufacturers won't bullshit (even if they do, they will state a higher top speed than actual, rather than lower) on their top speed as they tested their cars in ideal conditions.

You won't get accurate results by doing so with someone you don't know on the road as you won't know whether that person is driving at maximum speed or not. Try it out with someone you know, so you can have a much more accurate benchmark result.

I'm not sure about the real top speed for Waja manual but should be higher than my Iswara 1.5i auto. My friend claimed it is capable of over 190 km/h. That time I asked my friend (driving Waja manual) to purposely follow behind to gauge my top speed, so I can get an accurate benchmark result.

If you had a chance ever visit a car research & development plant, you will know that they do try out their top speed in practical not theory. In overseas (not sure about Proton though), the car manufacturers will even test top speed of their cars on an ideal condition speed circuit.

And yea, I would like to ride on your car to see it touches the limit of 180 km/h & how's the speedometer condition. Personally I had not driven an Iswara (1.3 manual & 1.5i auto) capable of reaching 180 km/h on the speedometer (disregard its faultiness & out of calibration), so it is a good experience for me.

I know they do on highways too but what I said is that overseas car manufacturers do it on special circuit too in order to test the really maximum speed achievable by the car they manufactured.



As I said many times, it is a faulty & out of calibration speedometer. Another possibility as pointed out by gouki is the 4-2-1 extractor.

Another point is that I had raced with a few unknown Iswara/Saga 1.3 manual (Limited Edition & LMST) before on highways, none surpassed my Iswara 1.5i auto (peaked at 170 km/h). Whether these people are doing full speed or not, I'm not sure but none of these cars which tried to tailgate or race managed to smoke my car before. I need to contact any of my old friends whether they own any last batch of year 2004 Iswara/Saga 1.3 manual, so I can test & know the actual fact of the 4-2-1 extractor existence.

By the way I had not test driven a Gen2 before, therefore I cannot make any comments.



It comes with the 4-2-1? If it really do then the story is different. That thing used on my friend's Wira 1.5 manual & really exhausted his car's engine.

I'm saying that in response to kcng's reply about car manufacturers using theory to get maximum speed, whereby in reality it is not just theory because it involves practical too.

I'm not sure about other stock Iswara 1.5i auto but mine is peaked at 170 km/h, no matter how long the straight road is. And no, I did not feel my Iswara is the fastest as I drove an Iswara/Saga 1.3 Limited Edition which achieved 175 km/h on the speedometer (the meter is slightly faulty though). We are sharing actual facts here & exchanging informations about Iswara/Saga cars, not to challenge who's car is faster.

However as enlightened by gouki, if the car comes with the factory preinstalled 4-2-1 extractor on Iswara/Saga LMST 1.3 manual then I believe the 180 km/h is achievable. Otherwise, no way a normal stock Iswara/Saga 1.3 manual able to achieve that speed unless assist by a steep downhill.

A few friends of mine & myself who drove Iswara 1.3 manual before can't reach 180 km/h at all. All of us complained that it has not enough power & top speed, some even commented they frequently defeated by Kelisa 1.0 manual. However a few of my old friends did managed to reach 180 km/h (& even over) but all of them claimed that their speedometer is not accurate or even faulty. Weird part is that I never got passed by any Iswara 1.3 manual during race & tailgate events at highways, although my current Iswara 1.5i auto only able to achieve 170 km/h. This is why my conclusion is that 180 km/h displayed on the speedometer achieved by some forumers here is not real (unless fitted with the 4-2-1 extractor by default). I'm sharing my experience & facts, not to demotivate you guys. I'll do another test with a Iswara/Saga 1.3 manual LMST when got chance, so I can get another more accurate benchmark result.

Why not you try driving an Iswara 1.3 manual at 180 km/h on par with one of your friend's car & share with us the results here? I planned to do that myself too when I got the chance, just to prove if I'm right or wrong for one last time. That's more practical. You guys seemed very worked out with this & confident of the 180 km/h speed, whereby my group of friends are all skeptical about Iswara's performance & as I said some of them even got beaten by Kelisa 1.0 manual for a few times.

The problem is Kelisa's top speed is not as high as 180 km/h, which supports my conclusion of 180 km/h achieved by you guys' Iswara 1.3 manual is not real. By the way, Waja 1.6 manual can smoke both Jazz & City 1.5 i-dsi & please do not compare with a totally different engine technology like rotary as featured in RX-7.
