haubstr Posted July 16, 2008 Report Share Posted July 16, 2008 My dad bored his L20B out 20 over and now needs new forged pistons to compensate for the turbo he is putting on(got the turbo, exhaust manifold, and down pipe for free). The turbo is off of a Corvair Spyder, so probably not much boost... What would be the size of pistons he needs for this? Is there a stock Turbo Z engine we could get the pistons from? Thanks Quote Link to comment
