hello all sifu... i just wnt to ask some question. I want to modified my 1.8 4g93 turbo engine. What is the most suitable piston can use inside the engine?

u can try mazda B8 or B8 210 pistons,the size was 83mm and another option is da toyota 4AGZE pistons,81mm( same as GSR but good quality,can wistand high boost )
or 0.50 which is 0.5mm bigger then GSR...:_:

Ya... 4AG piston... that what i see a 4g93t did it with 22 pound (1.5bar)
If your are think to boost it that high... No problem soo far been using for bout a year...

b8210... if im not mistaken,the piston is a semi-forged..

I think with good proper tuning, 4G93 GSR pistons has been proven to withstand 260++ On-wheel Horsepower @ 26kgs of torque

for info to all sifu, my engine is a bolt on turbo. Used 4g93P block with GSR head. Evo 2 turbo with fin up-grade. Custom intake manifold. Evo 2 throtle body and wiring. Replaced chip for fuel mapping,ignition and cut off to 8500rpm. 450cc injector with fuel pressure at 3.5bar. 2 extra injector activated when boost above 1 bar. The piston crack when i run boost up to 1.8 bar..
