4G91 Gang..

[eci4ever]

iswara204, add 93 airflow sensor, it will be easier to fine tune..ntw this type of mod can improve power with good fc..tried before but with 91block..

me too, currently i used 4g93 sohc except my block is 4g91, Actually i bought a 4g93 sohc halfcut and i bought 4g91 dohc engine kosong. Then i put just 4g91 engine with gearbox into 4g93 halfcut and put it in my car.

I donno whether my setup is correct or not. But the FC is quite low and the engine is less problem.

alright..any idea how much is the market price for it?? is 93na and 93t same air flow sensor?? hehe..sorry la just ni playin car...

 

[iswara204]

think so...unless u hav bigger piston loe...
iswara204...y dun just use 93 block terus?just askin...

93 block mahal la bro...and my friend just tukar the ori timing belt, then must change again for the 93block..if use 92, can use back the 91belt because the stroke length is the same...is simple words..for now, budget kurang la..he want to modi his car in a certain budget..later ada RM, boleh upgradre lagi..hehe

yes i am.. All part is 4g93 sohc including wiring except 4g91 engine + gearbox. My computer box no is 6758.. Who else here using setup like me? I do this setup because i can't find 4g91 halfcut. Only 4g93 sohc available at that time.. I don't know wether this setup is ok or not...

no lah, mivec extractor not too big ler gor 4g91..the different is the curve n boresize..its just like 93 extractor but different lenght..im using mivec extractor header but with custom downpipe, ok maa...

iswara, 93 aflow 93t not same..cannot use turbo one..if not mistaken 93 aflow code is 455..price around rm100-150..

I prefer this setup, if U changed ur block to 92 or 93, ure no longer on 91 rite, the originality of 91 is not there anymore. And if U play car, cannot enter the 1.5 category anymore hehehhehe.
Letsay If U try to smoke 1.8 and loose, u can still say, my engine 1.5 maa, and if U win.. wow! u can talk big.. rite?

erm... block balancing around rm500-600, boring the block about rm700, piston rm400... performance bearing.. rmxxx .... erm... estimation only..

 

[gabai]

price depend on workshop ler..piston 92p got ppl sell in zth her rm150 only..bearing like acl rm190..balancing n bore block depend on workshop..but rm700 for bore block only i think expensive ler..balancing,lighten n bore can do 1 shot..cost rm650 around that..try other workshop ler..

if use back the mivec's ori downpipe also ok rite?

 

[gabai]

mivec extractor 4-2-1..ori downpipe, the 2 part is shorter than 1 part..u compare with tuned lenght powerzone..its different..power n fc also can be different..hehehe..
