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...
bro...me also wanted to convert turbo kit for my 4g93p but i'm really confusing 'bout the piston and block!!some people told me notnit to change that just put the metal head gasket 1.5mm, drill the block and the oil sum!!ayaa...can i use 4G93P head ar??can u help me all sifu2.....:cry_smile:
for your info... i had put in CA18 piston inside the engine. also with the conrod. is'it can stand for high booost. the size is 83mm. and i used td05h turbine.
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..
