all sifu, how about 4g15 using 4G18 stroker kit + S4PE high Comp piston??
got any sifu do it before??

4G18 crank shaft and campro 77mm pistons. Yes it has been done.all sifu, how about 4g15 using 4G18 stroker kit + S4PE high Comp piston??

High compression, the will need RON 97?If use pv6 piston maybe can crack if abuse everyday for racing.better use fto piston 78.4 also and high comp.(got bonggol)..
last time sold my fto piston to sp4h campro guy.he say lots of campro guy doing this mode.so means wira should be a problem too....?
78mm!!! Wah!!! Did you redo the liners? Isn't 78 already touching the water jackets?the car is finished already. used mazda b6 piston dome type. 78mm one. now even gear 5 can reach rpm 7k. quite an accomplishment. i decided not to use perdana v6 piston because its 78.4mm. too big for us. thx for all your help.
Not necessarily la vr2, can be adjusted via ignition timing. If it's a VDO, it's automatic. Best thing is VDO will adjust based on your octane too so powerrrrrrrrr when you want it.. only bad thing is it takes about a day to self adjust.High compression, the will need RON 97?
Mine can't, and when tuned too low the power lost....78mm!!! Wah!!! Did you redo the liners? Isn't 78 already touching the water jackets?

Stroke will increase displacement a bit. But by how much exactly depends on the crank you use, the conrods, etc. Measure it with the cylinder + oil method la. And it might just still be a 1.5++ rather than a 1.6. Since stroke is different you'll definitely feel a torque differencelol .. it takes about a day to self adjust ...

if 4g15 mod 1.6 stroker kit, the piston remain unchange?
can i assume my engine displacement has increased from 1.5 to 1.6 ?
Depends on the car make. If like old Ford models the 1.3 and 1.6 shares the same piston size, only that 1.6 have longer stroke to increase it's capacity. Long stroke also better low end torque.Stroke will increase displacement a bit. But by how much exactly depends on the crank you use, the conrods, etc. Measure it with the cylinder + oil method la.

hi boss,hi bro,
u can try:
campro piston kit
s4ph - low comp piston 76mm oem spec (1.6) (willl give u 11-12bar on comp tester)
s4pe - high comp piston 76mm oem spec (1.3) (will give approx 16-18bar on comp tester) (dome piston)
or u might try
s4ph/s4pe 77mm piston
the price roughly rm350-450 including piston ring (proton part center price)
