Proton Wira Diesel 2.0
Posted 20 March 2006 - 09:00 AM
mind to send me some photo about your engine, especially the fuel pump
People who own this type of car for sure much be serious roadrunner, else,
they will not able to cover back the stupid high road tax imposed.
Therefore, don’t be shocked when you receive a used car that clock few time
more mileage compare with the same age petrol car.
About the vibration, initially I also try hard to find solution, but when I
look that Frontier, Ranger, L200 engine vibration, in fact, not much
different, so now I change myself to get used with it.
From what I know, the vibration is related to the knock generated, also
partly because of the mechanical fuel pump that work like a machine gun.
(the tak tak tak sound…). This type of fuel pump is not possible to perform
multiple stage fuel injection, not like Hilux, Sorento and Rextron that
using a electronics controlled common rail injection system. That can
control the fuel injection into several stage, in order to reduce the
knock. But…. is really heavy to maintain the system ( with my current
income level ), therefore, I still prefer the conventional machine gun system….
I notice a Rextron blowing a long tail of black smoke for quite sometime
already…. must be fuel system problem, but the owner not dare to go and fix

I am driving a standard wira diesel NON turbo so My fuel pump should be
same as the 1 in your car. I have seen 3 units 420TD and the throttle cable
is NOT CONNECTED to the fuel pump. It goes a switch that resembles a volume
control. so when you play with the throttle it plays that switch, something
akin to turning the volume up and down. That is what I mean by drive by
wire. The wira turbo is meant for export to europe. that was in the late
90s. at that time all the european cars are already on euro 3 diesel
engines, which by the way is what we call the common rail here. the engine
in our wira non turbo is perhaps entry level euro 1. what one of our friend
says here that the 420TD is the same engine as the non turbo is wrong. If
it is would our proton BHD be so stupid as to send that car to europe to
sell; when all the europeans are already on Euro 3 engines. Would you buy a
pushrod side cam carb engine new car when all the current cars are DOHC
fuel injected ones?
There is a lot of first generation turbo diesel at the junk yard, same
generation as the non Turbo engine, you can convert the non turbo to turbo
but it is not just the manifold and turbo add on only. there is more to it.
The pistons must also be changed, the fuel pump that comes with the Turbo
engine must also be installed, only then will there be so reliability.
I have taken a lot of care to maintain my wira diesel. I am basically
selling engine oil( marketing guy) and I do have 2 workshop dealer in Salak
Tinggi(Sepang), the main customer are the airport limos, There use to be a
lot of wira diesels there.I have met a lot of taxi drivers there who tell
me the wira diesel is not reliable and need a lots of maintainance. A few
of the taxi drivers have driven my wira diesel and they all were very very
astonish as to the way my wira performs. I am very happy with it on this 2
aspects The fuel economy. RM 10 garuantee 100KM. it moves around like a 1.6
petrol. one more thing when I mention the final drive of the gear box . it
is not the 5th gear ok. it is the final ratio that is driving the wheels.
A lot of 5th gears goes after some time on wiras. That is a common part.

For a long haul salesman, your proton is much more comfy than a Frontier.
Although Frontier can carry more stuff, but after a while the slow and
floaty feel and manual bulkiness of the 4X4 you may feel "sian"... Also
with bigger engines, tyres etc, your costs are also higher. I buy lots of
Rangers and now Hilux for our Quarry Mgrs and have test drove them...
still I prefer saloon cars...

lot in my company. Parking space is so small and limited now day, the Unser
will not able to fit in the company parking lot, so, i have to park the car

sorry I did not notice yr reply. Basically For your info I am not exactly
driving a standard car. All my cars goes through some mods. I have changed
my suspension setup. It is on bilsten rally setup, so my ride is something
akin to a go kart.I have upgraded my brakes systems to bigger discs and
calipers so the braking needs getting us to. If one is not careful and not
wearing the seat belts;possibility of going through the windscreen is very
high. It is a bit of an overkill but due to my driving habits I cruise at
150 plus km on the highway. I constantly drive simpang pulai cameron
highlands under 45 mins. race downhill with a satria GTi once and I won. He
even bought me coffee after that because he was so suprise that a wira
diesel can be so fast plus non turbo.Honestly I am still very baffled by
this wira diesel that I am driving. It is my first diesel engine car. I
have not gotten the chance to try my hand at another unit so I do not know
weather it is just my luck; fluke shot or what. anyone insterested in
letting me try their wira diesels, just curious to know if my tuning will
work on other wira diesel or not.

Would you mind telling what aftermarket rotor & caliper you got? Where
did you get it done?
Posted 02 May 2006 - 11:46 PM
I did not go for after market stuff. The wira is basically mitsubishi, so I
just use parts from lancer Mivec. Plenty around at the junk yard.
There is some after market exotics from endless, brambo, ATE, 4 pot, 6 pot
but you also need to upgrade the master pump to higher volume to cope.
If you want to improve the braking on your car I can suggest you change
your brake hoses to Earls aeroquip ones; That should improve your brakes
and also keep it under safe limits. It is easy to overdo things and end up
having to powerful a braking system... whereby it actually becomes
dangerous and not safe. wheels locking up all the time.... OK.

slotted & crossed drilled following OEM size - National brand from UK but
using back stock calipers and change brake hoses steel braided. What are
your views on this?
Posted 04 May 2006 - 11:08 PM
you will get better braking, down side is your brake pads will wear very
very fast because the slotted part will be skiming your pads down at
rate, I have used slotted and cross drilled disc rotors before and ended up
replacing brake pads every 4 months or so. Nowadays there is a lot of such
parts and 99% of such parts come from CHINA!!! So just be carefull. I have
used such parts before and they are not bad actually for normal road use;
when you use it for race then have to carefull a bit because tends to warp
when heated up. with regards to braided hose, there is a lot from thailand
so have to know how to distiguish them. The ones from earls UK is good.
How much are those parts anyway. FYI I can get them at very attactive prices.

Looks like its time for another TT ke ke... need some recommendation on
rotors and pads as mine is wearing out soon.
For steel braided hoses, heard of Pro RS?
