did engine swap on my 94 delsol.Was 1.6 now its a h22a .Car has all kinds of tourqe,even had to buy racing axels.I snapped the first ones in it.My problem is v tech is suppose to kick in at 4600 and when its luke warm it does and the engine flat out screams,But when the engine is hot it kicks in at 5600.Could the problem be the o2 sensor, need larger fuel pump, vtech sensor.Im lost I need help.
