Newbie here with some questions! :)

You wont need an oil cooler if you're not going to track your car. Maybe get the 25 row if you're heavy on the gas in a constant 100+ degree heat.

As for other problems, you might want to pull the fuse for your steering lock. If you don't know what I'm talking about, just search it in this forum. It has been discussed about 6,000 times.

HP can vary depending on what dyno you use. But from what I've seen, properly built full bolt on will yield about 320-330 WHP. You're going to have to gut the engine if you want to see 350WHP+
