Really pistons are the best thing you can do. You can use srt4 pistons with 420a rods you just have to turn it 180 degrees. They sale for cheap but most of the time it is for stander bore so if you have not bored out the block you can maybe use them. Really pistons and rods is all you need to drop your compression when going turbo. If I were to to back and start over on my build I would have built up a 2.4l cloud car motor really that is the sweet spot and Its the same price to build as a 420a but cheaper parts and bit bigger motor plus the srt4 pistons and rods drop right in.
