Rally DNA in Proton Cars

Pic shown above isWira 1.8 EXi DOHC

Proton made 2450 units LE and 50 units of RS between 1995 to mid 1997.
New car price during that time was around RM80K-85K (plus minus accessories)

The 'uniqueness' of LE was :-

1. Full set of factory fitted Recaro Seat (custom fabric by Proton), internal door panel (same fabric use as seat) plus Momo steering and gear knob.
2. Unique rear spoiler (we call it 'Tiang Gol' as in 'Goal Pillar' in Malay but this is an optional accessories)
3. The one and only Step 0 (un-rechip-able) MMC ECU custom for this car/engine, no speedcut
4. Running on Co2 adjuster instead of o2 sensor *(down side is not so environment friendly but in term of power its much more agreesive than those running on o2 sensor
5. Engine parts were majority from Mitsubishi.
6. Unique F5M222VRXE gearbox (best gear ratio to match the engine power output
7. 4 round disc brake with ABS control (sorry no ACD/AYC)
8. Projector type fog light.
9. 14" AAC rim made by BBS
10. Only come in Marjaco Black color

'symbol' of LE is twin tip exhaust, plus tiang gol.
Chasis is 'stiffer' compare to 1.3/1.5 and 1.6. Lower arm, obsorber all thicker but its compatible to 1.3/1.5 and 1.6
After Wira LE discontinued, the same spec was stil use in Putra till 1st batch of SGTi..than the re-launch Putra in year 2000 (4000 or 4500 units) already with Lousy engine spec (o2, least agreesive ECU), interior standard only....

SGTi after 2001 would running on Siemens

The 'uniqueness' of RS LE :

1. Strip down version of interior (same like 1.3 where no Recaro, Momo, plus even no power windows probably rear only don't have)
Reason was told that they wanted the be as light as possible.
2. Running on Rally spec re-program settings ECU (still same ECU as LE)
3. 14" ROH rim made in Australia (lighter i think)
4. Only come in White color

There were many cars that PERT had. Most were built by ralliart Australia and Malaysia. Not all had homo docs. They started using the Orion which uses a Fiore tc engine. Next came iswara with a 2L engine, then Wira 1.6L car but fitted with a DOHC engine. Later stages came another version with the wira body but with a 4wd tc engine. It was due to be call Sembilu but somehow approval was not given to make this car as a street car so means no homo. So then came MMC to the rescue,  Evolution 2 which was rebadge to a Proton. That driver was local legend Jimmy Low. The Evolution 3 came when PERT sponsored MMC in WRC. Flying sikh drove 1 of the cars apart from Tommi Mäkinen and Kenneth something.

Somewhere in 1995, there was a 'special edition' of the wira with 2.5k units made for the homo docs to entry to rallying. One of the ex-mechanics who was with the team back then should be one of the car owners or maybe ex now. His name is Tajul who specialises in transmission and was the transmission specialist in the PERT crew mechanics.
