2.0 litre piston is what mm ??:regular_smile:DarkSin said:zakie : i dont understand what you're trying to tell the person here. 1st of all you talk about vtec (vtec rojak wif 4g93? i love to see that. )and then about a mivec that can smoke a vr-4 but it was stolen. what is the mod is the great green mivec i would like to ask.
I think modding the 4g93 n/a engine is all about your budget and your expectation. no doubt this engine able to produce good results. but again do weight the possibility of gain and $ spent on it. modding 4g93 n/a at higher stage will cost a lot and increasing the risk (cam shaft , bore block and like you mentioned droppping a 2.0L piston.)
dropping a 2.0 piston is not a problem but reliability of it is the matter of concern. would you place a bet on a mechanic that give you "reliable" source. the reliable source will be how long the mod been running and under what condition. it's crap if you spent grands and then see the engine torn apart 6 months later when you try to smoke a fast car. the "reliable" man wouldnt cover the losses.
i can say if you're spending same amt of $ on modding the 93 as transplanting a 93T, you should consider of goin for the forbidden fruit. gain per $ does make more sense.
you can try visit www.4gtuners.com and you will get tonnes of info over the 4g93 engine modding and debates on it.
Agree with you, that why i asked:regular_smile:Yong_5290 said:2.0 piston is 85mm...comfirm cannot put in...if can also the piston floating wit water
max is 83mm and 82mm is safe

Geng,,,2.0 pistons how many mm ?? what is the original sleeves size for 4g93 ? which mechanic can plonk 2.0 pistons,,,,i wanna meet him lar.DarkSin said:yap. no need 25k. with all the thing mentioned, how much gain ratio over $ ? when modding, ppl need to weigh ratio performance gain per $ spent and also reliability.
zakie : what i'm saying is you're talking from the cloud. you need to be down on the earth to tell us what's the mod in your fren's car. rather just saying "my fren got a mivec can make a vr4 run for it's dollar."
if i got rm10k on modding 93 N/A, might as well i plonk in 93T. run stock.
basically any mech can plonk in a 2.0 piston n bore it but dont think he wont gurantee anything after the $ is collected.
dont always believe too much in this kind of claims. i remember a case many years back when my fren's EK9 mod bcame the early batch of "high compression" dream guinea pig by this big tuner in sunway which still exist till this day. the person claimed high compression mod that gurantee high revvin beast. after paying tonnes $ for the modding, the engine went to heaven in less than 3months. then the guy said "you see, that's the risk of modding. it's a new thingy and we both took the risk to try it and i'm charging you minimum for the stuffs...".
a lot of new experiments are being conduct on us. so we must becareful enough not to be 1 of the guinea pig. as $ spent and a torn engine will hurt our pride and wallet a lot.
