#MrTomush :
I could boosting 1.5bar my 240SX 1JZ swapped because my piston and con rod is uprated.
dude i ran 1.75 bar on my 1.5JZ and it supported like it was nothing and even put out 800hps like it was nothing. but check if your engine is an non vvti model because they internals are way superior just comparing a normal 1jz non vvti can put 700hp safely and only has a real risk of blowing arround 850-900hp
but for the vvti's one i saw lot's sending conrods further than nasa did with their rockets with only 600hp
