    Jessie was amazing to work with. Helped me put together an amazing engine package to meet my goals. I’ve had it in the car now for about 8k miles with ZERO issues. You cannot go wrong with EMS!

    Can’t beat this for the price! Engine had handled over 500whp with ease and plan to make 700 soon and have no doubt this will take it like a champ. Jessie at EMS is great to work with and I can’t say enough about their attention to detail and quality when it comes to their engines! Highly recommend
