i had a chat with one of the sales guy in perodua the other day. i asked him if the 1.5L engine in Alza is the same with Vios 1.5L?

He told me no. it's actually the same engine with Avanza, but not VIOS.

Is there any difference? I thought Toyota use VVTI and Perodua rebrand it to DVVT. But 1.5L engine should be the same for all alza, avanza and vios right?

Alza - 3SZ-VE
Vios - 1NZ-FE
Rush - 3SZ-VE

Alza = Rush, but detuned.

Do read up more on the engines as they are all different, although they have VVTI/DVVT across the range

Avanzas engine - coded 3SZ-VE - has a
cast iron block whereas the Vios engine has an aluminium block. The 3SZ-VE
engine, which also has two camshafts, four valves per cylinder and of
course, VVT-i (Toyotas variable-valve timing mechanism), is also used in
the latest Toyota models like the second generation Rush compact SUV
and even the Scion . It can be configured for transverse or longitudinal installation in the engine bay, depending on whether there is FWD or RWD. In the case of the Avanza 1.5G which has RWD the engine is mounted longitudinally.

Maximum power output of this engine is 108.8 bhp/80 kW with 141 Nm of
torque at 4400 rpm

although the 1nz-fe can also figure quite the same which is 80 kW (110 hp) at 6000 rpm with 141 Nm (103 ft·lbf) of torque at 4200 rpm.

what do you mean by detuned?

wow, that's very detailed explantion. i'm not really a car techie myself. so in layman term, can i say that 3SZ-VE has 2 camshafts, hence makes it more "energy" to run the car full of 5 adults, compare to 1NZ-FE has lesser "energy" to run a car full of 5 adults?

Detuned = less power

1nz olso twin cam with vvti
1nz are older from year back 99

i see. so avanza using the detuned one or same with rush?

so wat makes the diff between the yr 99 and now then? since both also twin cam?

Avanza engine = Alza engine.
both cars are manufactured in Perodua production plant

ok ok. so what's the diff between 1NZ and 3SZ then? Only year produced?

the block...

So, is ALZA worth buying & durable ?

I tot Alza's engine is same as Avanza's but detuned instead of Rush's

i think what they mean is
Alza = Avanza < Rush

yup aluminium block is lighter..cool down faster

cast iron block is better for durability, easier to be rebored but heavier thats all

Got any powerband chart for both Avanza & Alza?

Alza where got same engine as VIOS....you think Toyota gives you their latest technology meh....DVVT is older tech, VVTI is newer tech.

Also iron cast vs alumminium block.

But Alza is same as Avanza...with diffrent tuning.

hahaha..funny. then why on rush n avanza they said vvti since alza shared the same engine with avanza n rush?
nway the reason they give detuned engine because alza is fwd while rush n avanza rwd. the whp not much diff since avanza n rush might lose some power due to using rwd and differential compared to alza direct to the front wheel. plus detuned will give better reliability and fuel consumption.

Perodua uses DVVT as their notion for valvematic while Toyota uses VVT-i as theirs; not to be confused with Toyota's VVT. Toyota never came up with DVVT.

As a gimmick, Perodua uses DVVT naming replacing VVT-i for a 3SZ-VE in Alza.

The Toyota SZ engine family is a straight-4 piston engine series with its exhaust facing forward. This engine was jointly developed by Daihatsu.

The 3SZ-FE is 1.5 L (1495 cm³). Bore is 72 mm and stroke is 91.8 mm, with a compression ratio of 10.0:1. Output is 80 kW (109 PS) at 6000 rpm with 141 Nm of torque at 4400 rpm. It features VVT-i.

Applications:

* Daihatsu Terios

* Daihatsu Gran-Max

* Daihatsu Luxio

* Daihatsu Materia / Daihatsu Coo

* Toyota bB

* Toyota Passo Sette

* Toyota Avanza

* Toyota Rush

* Perodua Alza

vvt-i = dvvt
3sz-ve = 1nz-fe - (aluminum engine block)

settle?

if avanza engine = alza engine, which one feel more power? these two are MPV, look like underpowered?

Alza is sharing the same engine with avanza and Myvi 1.5

Avanza 1.3 engine also sharing the same engine with Myvi 1.3

Also Vios engine actually had higher engine displacement compare to Alza engine.

Cannot. 3SZ-VE has longer stroke - which is a common recipe for higher torque @ lower range but at the expense of lesser top rpm.... so no idea why MyVi 1.5 uses this.

I think it is because myvi is a city car? In start stop traffic low torque at low rpm can be lethargic to drive

A city car need CVT more.

It will cost more.

More or less. Avanza use rwd, will result few hp power loss even tho avanza hp a bit high compared to alza.

Err Vios engine more super power.. If not in Toyota for entry car sedan and selling Rm80 and above..

Nothing can flight with Vios engine at all.
Myvi engine is lowest cost = intel Celeron.
Vios engine = Intel Pentium.
