tell us more abt ur car:

1. What car r u driving?

if u need power then upgrade to 1.8 mivec
juz change the engine block to 4g93
then do set the setting for ur ecu
set when the mivec kick in
piping muz hv the correct size to suit ur car cc so that there wil hv no any lag of power
high cam n performance cam shaft wil help
a fully balanced engine will help u to increase the power oso
then if u still feel underpower bolt on turbo or supercharger or NOS will definitely help u a lot
but bare in mind that mivec will never will a vtec in standard condition
sometimes mivec will full also hard to win vtec(this is my experience)

so wat car u r driving

but bare in mind that mivec will

Dear mirage2929,

I'm driving mivec-md in wira aeroback around 2y++. So far no break-down along the road. A good thing on mivec-md is the engine can engage mivec system twice. Normal mivec just once at +/-5000 rpm. Can you feel that??

Last year , I upgarded my engine to 1.8 with 4G93 block, bigger t.b., bigger injector, 6" open pod air filter. Installing SAFCII to re-setting the ECU. All at Hyperrevved, Pandan Indah. Good Tuner!!! Anything just pm me.

Now, planning to join the turbo member.

MD have kick in in twice ?? I think u r wrong bro ..
For mivec MD, below 3000rpm will run only with 2 pistons.
after 3000rpm, then run with all the 4 pistons. ( like normal mivec / engine )
high cam only kick in at 5200 ~ 5500rpm.

There will have many way to mod mivec engine, all just depand how much u can affortable.

Talk about mivec-md, all 4 piston will run at any rpm but.... only 2 injector will inject the fuel when driving below 3k rpm of +/-90km/h.
MD will kick twice?? yes correct. but only when you drinve at slow acceleration. Just about 2k-3k rpm. Can feel it at 1st & 2nd gear. Sometimes at 3rd gear. Anyway, i'm very puas hati with my engine.....

Zams,

Whats the cost of converting to 1.8 mivec?

 

[ZamS]

Hi,
Can't remember.Rasanya aroung RM1000++. Change 1.8 block GSR/Putra, bigger T.B, bigger injector. Did it at Hyperevved. Good tuner.

Bigger throttle body ?? is it aftermarket one ??

 

[ZamS]

Dear friend,

For larger t.b. , i'm using evo 1 punye. No modification, just plug & play

 

[jinkl]

let me shoot my idea la :)
first for mivec-md
change ur ecu settings to disable the MD
cams maybe use mivec standard, its difrent from the MD

my idea is, extract the power of ur engine rather than POWER MODDING and gaining litte from the standard

 

[boyzone]

mivec throttle body already stand at 60mm , is it evo 1 large than this number ????

Is depends how $$ u have..if u say normal mod is still can play wif vtec..don ever say mivec not a competitor..if u say vtec put 100k n mivec 100k is fair if vtec lose..

Mivec MD kicks in 2 times? Sure o not bro ... :emoticon_U:

Suggest u to change ur piston to high compression piston and put a thicker gasket after u change piston .... u will really feel wat is mivec kick's in .... :P

Hi cam only kick in after 5500rpm ....
