this is what happens when the 1jz spools. hahahaha.

also with the shorter stroke of the 1jz the piston speed @6500rpm is the same as the 2jz piston speed@7500redline.
this is wht the 1jz is better than a 2jz and 1.5jz. the shorter stroke allows the 1j to rev harder and higher. lighter rotating assembly is a cause also. lets say you jump in a camero or any performace v8 and floor it to redine. pretty slow rev huh.
now jump in a gsr or any small displacement motor and do the same. revs faster and harder. just like f1 and superbikes. samll stroke=fast rev. the quicker you can get into the powerband and reach max boost and hp the faster you will go



sure there is a replacement for displacment.
its called boost.
