i'm using a 4g91 carburetor on proton saga megavalve, month ago, i've change to adj. campully(arospeed) + engine racing pully (advan racing). after tuning and tuning and g-tech pro test, 0-200m can go 10.5 sec.
recently i feel that there is not enough power. need some help out there or some views(port and polish, putting a 4g93 camshaft etc... ), for info i'm using 1.5 megavalve distributor, not the 4G one. at least can tapau wira 1.8 sohc. hehehe
