First off without going into details there is a million things to consider when pushing the 400hp + limits with an engine. How do I know cause there is a giant hole in my bank account from learning the hard way. We purchased an engine from Enjuku racing from their drift team. They used to carry 4 engines. 2 in the cars and 2 as back-ups. We purchased one of the back-up motors. The bottom end is not stock not even close to prove it here is a pic of the piston we destroyed. ![http://i287.photobucket.com/albums/ll146/intensemotorsports/Intense%20S13%20Drift%20Car/IMG_2145.jpg](https://canada1.discourse-cdn.com/flex034/uploads/speedlife/original/3X/7/a/7a622ef992192486aa61bddf29ec9d47136781a4.jpeg) --- _[View the full topic](https://forums.speedlife.net/t/building-an-sr20det/118136)._
