Using of high cam w/o ECU upgrade...?

[zarique]

bros and sifus,
maybe this is noob question but i wonder...
can i upgrade my 4G63T engine with high cams such HKS or BC 272 in/ex without having any upgrade with management such piggyback (E-manage) or SAFC...
i'm sure that with standalone management, it will be best...
opinions needed...
thanks to all....

u need atleast something to compensate the extra airflow
get a safc least , dnt want u to blow ur engine

 

[zarique]

thanks bro...:wavey:

for example,
with the install of safc+cam 272,
will i get the sound of revving up+up (vroom, quiet bit, vroom, quiet bit, vroom)...

 

[jinkl]

u dnt need cams to make that sound
that sound is caused by overlap , standard cam can make that sound with adjustments
hmm , dnt chase for sound, chase for performance la bro

:D hehe...
chasing for both...
since got no money to mod gns2...
recently change my piston to 1jz 86mm + metal gasket 1.5mm cause my compression for evoIII lowered down so less kick than b4 but boosting at 1.2bar...
thinking of gainning power from the head which is the cam...
hrmmm...

bro jinkl,
if due to changes in compression ratio from changing piston to 1jz,
can the compression ratio be up back with the use of a forged piston...?
what bout the metal gasket..?
advise needed...

 

[jinkl]

blur, u want to increase compression or reduce ?

 

[zarique]

rite now i think its reduce due to the 1jz pistons..
so i wanna increase bit mayb back to normal...
either reduce the metal gasket thickness...?
or change the piston to forged such wiseco..?
thanks
