i saw in terato's forum that a proton's chasis cannot stand the vibration
from a vr4 engine or evo engine and the engine would look as
if "tenggelam" in the engine bay coz the chasis metal is too soft. is this
true? any one of u has a wira or iswara converted to 4g63? does this
problem exist? thanks...

The Iswara and Wira chassis is used for rallying. True, the chassis of the rally cars are probably much stiffer then out road-going models but it shows the true potential of the chassis. Don't forget that the Wira chassis is very similar to the early Evo chassis.

Proton cars may have soft bodyshells, but they do have a good foundation (chassis).

True and False

A rally car is specially prepared i.e. Additional welding points are made.

And a stock mitsu (proton) chassis is not very strong; the SGTI was
improved on (clamed by proton) by having over 20 additional spot welding
points.

You can’t gauge how strong a chassis is by having a powerful enj. A stiff
chassis will still bend and flex like any other, the difference is it can
flex and twist more with out damaging itself.

Want a stiffer chassis, have more spot welding points or add a roll cage.

i agree with ballistic..

no.. the early proton models do not have a stiff chassis at all.

a stiffer chassis isn't just about handling a powerful engine in a
straight line.. a stiffer chassis helps components like your suspension to
work the way they were designed too. Especially in corners where a weak
chassis may twist affecting traction from your tyres. A stiffer chassis
can improve cornering performance, as well as provide better NVH.

Newer cars are a lot stiffer today than cars from the 80's, and 90's, due
to better engineering, and design. The waja may have quality control
problems that irritate, but there no denying that is has a very stiff
chassis.

As for the Evo's, their chassis has no resemblance to the original lancers
that donate their bodyshells. From the 3 all the way to the 8.. the
chassis is heavily modified, with extra metal bracings welded on, and
including up to several hundred extra seam welds on the new 7 and 8.

it is real .
i saw it in the magazine also . someone installed evo inside the hood and
mod his wira into real evo , 4wd mode . i still remembered that the
mechanic mentioned that they cannot cut the parts / chassis to make the
shaft smooth to the rear , this is because the wira chassis is softer than
the original lancer . they did mentioned about some extra welding point
has done on the wira too .
