Modding A 4g93 N/A Engine...Give ur comments pls ppl

[satria81]

Dear All,

Im in the mid's of tuning up my 4g93p engine.Doin this truly n really cos i dun feel the power of it .As a few ppl have told me its a worthy engine to be modded.Id like to get some ideas from all u ppl here.Below are the modifications ive planned.Anything better?....u think? pls do state it....kindly do not hesitate,thanks!

1)To renew pistons to high-comp,was thinking of 4g92 oversized size 100 pistons
2)To replace throttle body to Mivec 1.6
3)To Port n Polish cylinder head
4)To Replace the valves to bigger size but unsure what valves to drop in
5)To fix a adjustable fuel regulator(My fuel pump is ori 4g92p's)so just to contra
the fuel pressure

Any other mods that will make a diff in power or torque,pls let me know...now my pedal is like empty when i floor it....ive lost the torque that a normal 4g93p gives out....so pls help!Thanks ppl in advance for helping.

Additional Info
------------------
My engine is not from putra or gti or any malaysian spec.Its from the japan spec perdana/ETERNA body 1.8 DOHC.Never ever buy this engine from chop shop, its crappy n shitty based on my experience!

-Ecu Code-MMC 6123(weird ha,but true) with speed cut at 180 km/h
-Pistons are totally flat(real flat) now compared to msian ones with at least 4
curves on each pistons.This i think really making me loose power.

Note
-----
There might be some of u here who has the same engine n performs well.Maybe mine is a faulty engine n thats why it does not perform....so no hard feeling ha to u guys who have this similar engine....im saying all these based only on my engine n NOT ANY OTHERS

Main question, how much are you willing to spend for this upgrade? :regular_smile:

pm rep'ed

 

[lozo]

try 4g92p pistons. it increases the compression

 

[Yong_5290]

oversize 83mm piston

 

[boyzone]

one of my member run with this engine into his satria chasis. anytime can smooth local 93p engine. Is quite powerful engine.
since u r saying this engine is not good enough, why u dun want change ur engine ?? u will pay a lot in ur Rebuilt cost. After rebuilt, how long can this engine stand for ?? it is worth ??

For me . I will trade in this engine + save the rebuilt cost go to drop in a mivec engine.

just my opinion.

kua kua kua..... is not that i do not like mivec...
be-coz i've got a lot of frewnz who oredi spend thousand of kepaLa agoNg
just 2 make mivec goes fast.......
but at the end stiLL lose to v-tec.......
but now i just wanna see 4 throtLe mivec side by side with v-tec,
but still dont have the chance to watch it.......
arrrgghhhhhh !!!!!!.......

 

[Excalibur]

You might haven't seen it.... but mivec side by side with v-tec is just biasa...
If you are driving a vtec and a mivec side by side with you i wonder how you face goes......

 

[tykoh]

is it true... mivec cannot stand a change with VTEC?
lets say using stock mivec 1.6 vs B16A vtec....
which one is faster in term of pick up?

 

[spyderslr]

answer is vtec....unless the vtec is in really shitty n hopeless condition lerr.....

mivec beat vtec...??...last time i know 1 green satria 1.8 mivec does.....but now no more....i guess lotsa u haf heard bout it b4, nicknamed Green Goblin......

 

[Yong_5290]

whose ppl who transplant 4gx engine sure lah is mitsu o proton...then pula u ask him go for vtec...

if can i go for rotary loh...road tax cheap sumore

 

[boyzone]

power to weight ratio is very important for mivec ownner , is the only way to beat Vtec by stock to stock condition.

 

[zakie]

yup,
that was the Last ever Green Mivec own by my frend, he he he he so damn fast wan,
even vr4 side by side oso will not stand againts that mivec...... i think that was 2
years ago be4 his car was stoLen...... cant remember oredi maa....
reaLy do miss this mivec performance....
