4g15(Wira) covert 4g18 stroker kit

[issuzark]

Like you always say, no replacement for displacement.......hahhahhahahaha

Hell yeah. Now that I drive a 2.0L, 1.5L just won't do it for me anymore...

4G63 swap!

 

[vr2turbo]

4G63 swap!

You cannot unless illegal.....hhahhahahha

You cannot unless illegal.....hhahhahahha

So tempting.

4G63T transplant in a C91 chassis is just asking for trouble. Accident, cannot claim assuming you survive. That chassis was not designed for that much power either so expect it to crack over time. Nose heavy too.

I've seen a C99 Putra chassis crack with a 4G93 NA modded car. 4G63 in a C91? Good luck seriously.

But since you're gonna go illegal, might as well spot weld the chassis while you're at it.

Go big or go home? True that. It's already illegal so I might as well do some spot welding, and foams to increase the rigidity as well just for good measure?

That being said, isn't a Putra running 4G93 stock? How much NA mods did it have?

Did that car have added aftermarket bars or any other measures taken to stiffen the body; specially in the front section of the car.

 

[^pomen_GTR^]

my c98 satria 1.6 auto already crack worrrrr.... old car...normal penyakit...

no worries...Ultra racing got all bar we need...

4G93 NA mods with some cusco bars here and there. This was when UltraRacing was still new in the market. Spot welded chassis, solid mounts and stripped. On wheel it was over 300bhp+ and even with LSD it was twitchy. I never drove it because the owner was relatively short. Had a full bucket with modded brackets to cater for his height. As for the mod list, it was extensive to put it mildly. Without the standalone the idle speed was 1k-2k-1k-2k-1k God knows how he drove it like that for the time without the standalone.

The funniest story about this car was his bumper canards were installed at an overly aggressive angle and during sepang, the front bumper snapped off. The fella claims over "downforce" the front

Anyway in the end car was scrapped I think, or was it sold? The front cross member area had tears (don't know the actual name of the area but it was near there) and everytime the fella revved can physically see that tear flexing. If he did sell the car, I pity the new owner. It would only be a matter of time before the car becomes condemned. Hopefully the new owner was smart enough to demod and use normal mounts. Too much stress to the chassis la I think.

Thanks for sharing.

Still we shouldn't place all the blame on the engine upgrade. With more power available, the desire to speed increases

The driver behind the wheel has to share some of the blame. Chassis damage results from aggressive driving. Stuff like extreme corner Gs or high speeds over undulated surfaces. The chassis is severely flexed. Over time, this flex translates to permanent damage.

no worries...Ultra racing got all bar we need...

yeah, I feel the fender bars are particularly important. Mind sharing what other steps you took to stiffen the car? I recently autofoamed my side sills. Car is so much nicer to ride in now.

If going illegal, why stop and spot weld, add iron bar and strengthen.....lol

Add iron bar? Still a street car for daily drive mah...

Say already mah! if going illegal.....hhahahhahaha

 

[Izso]

roll cage!!!

 

[issuzark]

roll cage!!!

No need to be so obvious gua... Tube chassis

 

[vr2turbo]

roll cage!!!

Bro. Izso, Bar in engine probably can hide. Fit Roll cage, you know who get shot first.....hhahhahaha

Hmm .. would it not possible to custom a roll cage to be hidden within the ABC pillars?

4G15 Wira not C97 chassis?

Just because of the weakness in chassis, the whole engine is wasted... Too bad... I wonder if the owner manage to source original Mitsubishi chassis like those of CA4A Mirage Cyborg or Mirage Asti, will these chassis be tougher than then C99?

Hmm .. would it not possible to custom a roll cage to be hidden within the ABC pillars?

No place to hide....

 

[parakey]

No place to hide....

Referring to the attached picture of Proton Suprima. Note that some bars align to the pillars.

I don't mean a full fledged roll cage with tubular bars but perhaps modify a bit using flatter, slimmer tensile ones which can later be hidden with the pillars' plastic covers. Roof has ample space to add tubular ones. It's a bit like reinforcing all those pillars and connecting each to the strengthened roof. Should act similar to a light duty roll cage. Likely won't need to wear a helmet driving this.

He He .. with those bars added, car will be heavier. No more pickup :damnmate:

Edit:
LOL .. don't mind me. After re-reading this post, I feel as though my head got knocked on one of those bars. :stupid:

the strongest proton chassis was the one and only version Satria GTi R3 edition...true double spotweld (i think it was more like triple spotweld on some area)

i use fender bar+4point strut bar....but didnt believe much on the undercarriage bar especially the one hooked to the already sturdy engine subframe....


autofoam is good start...u can upgrade using the track package....

that would be just impossible.....from my experience with rollcage....my only suggestion is u custom order whole rollcage set from chrome-moly material using 1"-1.5" diameter tube pipe and as close as possible to a pillar, b pillar and across floor at b-pillar fully welded along with sturdy base plate at all 4 point to the floor as well as retaining plate placed at strategic spot and secure using bolt....and final job to mask all of that via whole interior panel wrap in fabric (means cut stock interior panel to clear the rollcage and then wrap the whole area with interior fabric.... (floor can do with similar pattern of floor carpet and wrap around those cage to hide the obvious....

thats the best we could do if u really want rollcage and remain stealth from outside....but whoever steps inside your car definately will notice that....
