i have read somewhere and cant remember if it was petrol or diesel about putting a thicker head gasket on to lower compression rates then upping the fuelling are air flow greatly to get more power. speaking to a friend he says that doing this would make my aaz a biatch to start when cold and not worth the gains!
i have moded pin in pump, got a k24 turbo to put on and intercooler. got a manual boost controller. before these go on will get an egt guage boost guage and a oil temp guage
is there any other mods i can do apart from what i already done to help me on to 150 bhp+
Don't do it. It doesn't lower the compression significantly, but undoubtably has a negative effect on the turbulance in the swirl chambers.
so no to thicker gasket!!
just enquiring what else can be down for more power
