im keeping stock internals.... i figure stock compression ration (10:1) which i know is really high for turbo aps, with low boost (4-5psi) is the equivelent of low compression (8:1) with high (10-15psi) boost. for half the cost and less than half the work. im not too worried about toasting the engine because i can always rebuilt. unless i fuck up the block, then i will swap a new engine. but im thinking i can accomplish what i want
