Twin Cam Project for 4g92

[pifecto14]

I just got quoted by a mechanic saying that will cost RM1900-2000 for the conversion...wah lau abit pricy than i thought...:(

Anyone here actually did transplant the mivec engine head??? Wonder how much would that cost??

 

[leftfoot]

i;m not sure bout this but i think u also need the ecu if changing to mivec head. and that also will involve wiring. can easily go above rm3000. i think la.

1900-2000 for 4g93 head conversion? some of us i think did a lot cheaper. maybe 1500. try buying the head urself la. i think it only costs 400-500 for the head. then u'll also need a distributor that can fit that head. can easily buy from a forum member. then try asking ur mech how much he wants to do the conversion. sure he cannot markup the price of the items anymore. except if u have to change ur valve seal, timing belt for sure . best of all, try looking for a head thats in working condition and not those from chop shop. u'll save alot more. good luck.

Well besides, chop shop i dunno where to get the 4g93 head. Plus how to differentiate that its a good condition or a bad cond. head also at doubt.

For those who use less than 1.5k for the conversion, mind sharing wit me the location of the mechanic??

Thanks

yup, try to find a 4g93 dohc head in zth lah, is more cheaper than chop shop about 400-500, last time one member offer me 380 including the manifold and spark plug but my mech advice don do this conversion(bcos he said no power, just waste money), now feel a little bit regret y don take it..
totally cost will around 1500, i heard from members from this conversion thread. alien_03 and deacon bro got one to sell, try to ask them and get from them. if conversion need 2000 fees, i think u should not go do this conversion, it is not such feeling that match v this amount do it.
anyone successful can share v more details like performance, fuel comsuption, torque, hp, and any attracted pics? hehe.. nice conversion.
actually i also go ahead v this conversion v my sohc 1.8, but i am confusing now whether go v mivec head or just dohc head. mivec will give more power but following v the cash flows also. some more need a skillful mech, if not, mivec din't operate properly.

Any more new news on conversation to DOHC??? hehe

 

[pifecto14]

damn, still have doubts in doing this conversion...

nelson when u converting??

 

[Blowfish]

Actually to do this DOHC conversion, can use 91 head also. Recommended by my foreman. Coz according to him, the 93 head ports are a little too big for the 1.6 block hence u lose more on low end. With 91 head its actually more suitable. In fact most of the ppl i know have done this conversion with 91 head. Just need to get the distributor.

FYI, I have a complete 4g91 DOHC for sales ( everything inside head completed ). .An extra that I bought. Its going for RM300 non nego. Blardy cheap already. HEheh Pm if interested.

 

[pifecto14]

hmm...not sure bout using a 4g91 head...Already there is a member saying that using 4g91 head on 92 block will have problem like sound and all.

Btw, Do u guys know where can i find cam pulleys (adjustable or non adjustable wans) for 4g93 engine head???? Or mayb recommend any shop which i can able to find it around PJ area??

for thoose who wanna convert 2 mivec head.. i think u dont need 2 get the wiring n ecu as well... coz mivec is not like vtec.. 2 activate mivec just need to tap 2 wires to battery.. means >> only 2 wires from insed the head, attach wit suis the 2 battry.. then can activate mivec manually.. if u hav the extra cash can go 4 VAFC.. my formen thats damn lazy did this wiring n tought me.. he say sav budget ma... heheheh

 

[pifecto14]

Guys, anyone of u here using 0.4mm metal head gasket along wit this convertion?? Will it really create higher compression ratio and power?? wats the pros and con of it??

 

[e819]

ive used 0.4mm metal gasket b4... knocking kaw kaw.. better don use ler

 

[pifecto14]

Dude, the knocking sound comes once in awhile or its there as soon as u start ur car??

its advisable to get the complete mivec wiring and ecu coz it runs on different fuel n ignition maps b4 n after the mivec activation point.....yes, u can still activate mivec wif various types of method, but it just wun perform as good..... =)

[kksoon]

long time no c.....

I'm back....all my bro......how r u guys?:_:

great news guys!!!
i managed to clock 9.64 seconds from 0-100 last night. i know its not that accurate but me and my skinny friend did it many times. well we got 10.2+ and 10.3+ in the first 2 tries when the air cond was on. furthermore the 1st two tests was done on an incline road. so i should say that my car can go under the 10second barrier and i didnt even change the cams!.

leftfoot, go run man....good timing u have there.....

kksoon: wei, man, long time no c u online and reply here, how about ur engine? modified wat part already??
