how fucked up would my sohc run if i ran vitara pistons in my engine before going turbo. i need to pass emissions next month and i am trying to get my engine built before then but also maybe want to go turbo.

well your compression is going to drop significantly but if you tune it right i dont see why it wouldnt run right.

You would lose a little power because of the lower compression, thats about it, it would run perfectly fine otherwise. Vitara's compression ratio is 8.5:1, stock pistons are around 9.2:1 i believe, not that huge of a gap. You could always have a few thousands milled off of your head to compensate if your that worried about it.

You will throw a cel. Probably triggered by o2 sensor

Incorrect fuel burn. However, I passed with mine. I just unplugged my ecu right before he tested it so the cel went away temporarily.

In Cali, they plug the machine right into the computer. pulling light bulbs doesn't work. the cel will show up anyway
