I'm not sure but no is my guess, since 4g92 SOHC cuts off at 6.8k RPM, a point where you haven't even get the most out from the DOHC head which is at 7k RPM according to Wikipedia.

Please raise the rev cut if you're planning to do the swap, also if possible, throw in some MIVEC pistons. ;-)

well.. some trick for mitsu/proton engine can be done to use back SOHC ecu.....

providing that all sensor was same (ignition and injector) u can use back SOHC MAF sensor along with SOHC ecu.... :adore:


about the DOHC head whereabout i donnow.....might be easier to source out 4g61T(1.6T) engine than 4g92 DOHC non mivec head...

i have a pivot megaraizin installed in my car. i noticed that most of the time it shows two readings. 4.7v and 10.5v if i remember correctly. i understand thru some research that 4.7 is the lowest voltage at the start of engine and 10.5 is the real voltage. my questions is how will i know if this is healthy? how will i know if its time to change the battery or my battery has some problems?

i went thru this but still dont get it...
