4g15(Wira) covert 4g18 stroker kit

[issuzark]

Rebore the block then?

More cost, then got to calculate whether the 0.5mm worth the trouble and cost?

Use Saga pistons better. 77mm.

... modifying my wira with standard 4g15 carb to 4g18 stroker kit

Pardon my ignorance but how many additional cc of discplacement will this yield?

I know a guy or two who'll be able to do this. Personally if I were you I'd play with carb with the stroker. Changing to EFI might make tuning "easier" and may improve your FC but don't expect miracles. If unlucky you might have initial problems with the wiring and that will be a headache to troubleshoot.

Get the 4G18 crankshaft, not the campro one. Then get the Saga 1.6 pistons. Bore out the cylinders (reline if you have the budget) and hey presto, stroke + oversize pistons.

Iszo bro, i see people use to say saga 1.6 piston if used not reliable true ah bro ?

Pardon my ignorance but how many additional cc of discplacement will this yield?

about 100cc

 

[parakey]

about 100cc

So you budgeted 5-6K for converting your 1.5 into a 1.6. Would it not be cheaper to buy and drop in a 1.6 engine instead?

Sorry for the questions. I am a complete newbie with such things.

Nah. All pistons are the same unless you go for forged pistons. The only reliability issue is if you don't do the oversizing properly. 1.6 piston is going for 1.7L mod already (1650cc++) so the cooling system has to be done right and the cylinder liners must be replaced with strong ones.

Depends on how you stroke. Just the crankshaft alone is about 100cc but the stroke will increase as well, increased torque and more usable power band.

You're probably right. But personally the hassle of registering, JPJ, puspakom and all that is a turnoff for me. Especially if your car is already tinted.

Converting, then everything is new. Pistons, re-bore etc., will be like a new complete overhaul. Transplant engine sometimes is a gamble, how good the engine is....:hmmmm:

Last time Izso suggested to use 77mm CFE pistons from Proton with 4G18 crankshaft.

That's the same Saga pistons he was talking about I think.

You and bro. RENESIS have the right car to mod this.....

Did I say CFE? :hmmmm: Sorry, meant campro. CFE are low comp pistons right? Don't think you'd wanna use low comp on a NA setup.

77mm is the max you can go with 4G15 I think. Any bigger and you run the risk of making the liners too thin

Eh, your 4G15 is MT or AT again?

Hehe, both also 4G15.

Well, you previously mentioned it here.

Mine ah, 3 speeder AT.
Yours is manual Iirc? And MMC as opposed to VDO?

Yours now more stable......heh heh....

5MT MMC...

Mine stock only...

 

[vr2turbo]

5MT MMC...

That is what he wants.......
