Modifications for the Proton Wira


The Car Tuning Guide look at the Wira tuning options. Which are the best modifications for the Wira.

Available in standard form with power of upto 135bhp (depending on the year), so this goes to show the tuning potential of the Wira. From this you can increase the power from anywhere between 148.5bhp to 229.5bhp with modifications varying from a few DIY mods to some pretty major engine work. The higher you go the more unreliable the car will be and you should expect to have to rebuild the engine regularly if you want to extract silly power. A big forced induction upgrade would be needed to push beyond the 100bhp per 1000cc limit.

If you have a lower powered Wira your best bet for a mod would be an engine swap with the 135bhp Wira Hatchback. The more powerful Wiras respond exceptionally well to tuning mods. The most frequent modification we see on the Wira include sports exhausts, air intakes or induction kits and a fuel pressure boost valve.

FASTROAD CAMS should be next up on your tuning list and will offer big power gains on the Wira. Turn your attention next to the Wiras engine head. With a good gas flowed ported engine you will see much better mid and peak range power.

The most powerful Wira Hatchback in our database offers 135 bhp. From this you can increase the power from anywhere between 148.5 bhp to 229.5bhp with mods we have outlined above.High on your list of mods for your Wira should be handling improvements. The Car Tuning Guide do not recommend lowering more than 35mm.
