[QUOTE="speed2horizon, post: 4058206, member: 30831"] basically, e-manage n safc are also piggyback. But the parameters involve in tunning are different. An safc is user tuned based piggyback. It only involves rpm n +- fuel with 2 different throttle position. Hi or low throttle. So, total 16 set point. Where e-manage is more sophicated. It involves rpm, throttle position in percentage, input of fuel injection n also reading for maf/map. So, total of 256 set value. So, which one do u think would be more reliable in the product's reliability. fuel tank should be given together with the halfcut. If using iswara, just change the fuel pump. heard Jian Hang at batucaves created a set of 4-2-1 for campro @ neo according to the mugen design with the bryon detachable. Heard he say will feel the engine lighter. high cams?? Gti/putra cams already have higher lift compare to 4g91. To achieve a 1.6 stroker, all u need is the bore up to 81mm. Cause the stroke are the same as 4g92 mivec, 77.5mm. By choosing 4g92 mivec pistons, u'll achieve 1.6L with 11:1 compression ratio. High enough for an NA. Equivalent to vtec b16b. So, why gen2 pistons? Piston pin all different, why all thVe hassle where u can use something plug n play... Porting head is something relative to individual. But a proper port n polish will require a bench flow test to make sure the flow in each port n runners are even. So far, only matspeed n nasty port flow have the benchflow. E manage + safc??? WTF is that? Microtech??! No need la. The ecu good enuf to handle. Btw, bro please give correct infomation n not just bantai only. Some ppl really get info from Zth. But if thigs. if the BTDC of the cams are set properlly. Can really feel the diff. [/QUOTE]
