Ok, I am going to swap a b16a2 into my si hatch. I want to boost it. What are the most affordable ways to lower the compression? What all can you do to lower the compression to about 9.5 :1?

 

[:@] just drop the cash on getting low comp forged pistons in it. if you use the thick head gasket, you only get the detonation resistence of about half of the actual CR drop you get. so you kill your low end power to run a couple more psi of boost. just keep it stock and keep the boost low, build it right, or wait till you can.
