4g15(Wira) covert 4g18 stroker kit

Saga 1.6 camshaft.

but how does a camshaft effect the displacement of the engine?

That's a very good question :D

Maybe this may answer an earlier query

WACForum -> New Found Secret Of Restroking Our 4g15

Saw the Campro alternative from here some time ago. LANGKAH2 MENAIKTARAF PRESTASI ENJIN 4G13 & 4G15 ANDA (enjin lain pon leh gak)
Didn't know it'd hit 1.7 though.

and there are reliability issues if we do so rite as what stated on both sites so i guess better stick with the 4g18 pistons or how about upgrading it to higher compression pistons

bigger pistons, thinner walls.....heh! heh!

okay. no more poisoning me myself. play standard only lohh with 4g18 inside

 

[Izso]

longer stroke = more cc
bigger pistons = more cc
put both together = a lot of extra cc

So it's about 1680cc which is approximately 1.7L la. Why cannot? My issue with the campro crank is that it's too skinny. I have no faith in that crank. Compare it with the 4G18 one, it's super thick in comparison. And personally I'd redo the liner and balance the engine. Longer revs, higher revs, more torque, ok mah

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...

Same here lah! Been on 2.0L turbo some more, when tried the 1.6L Tiggo, no way, must take the 2.0L one....hahhahahha

4G63 swap!

 

[vr2turbo]

4G63 swap!

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...

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

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