WATCH: How to build a RELIABLE 1,400 Horsepower LS Engine!


Today in the MotoIQ Garage we’re building a 1,400 horsepower LS based engine that will be powering Dai Yoshihara’s Formula Drift BRZ but could be used for any racing format just the same. Not only does this engine make huge horsepower but it will do it reliably all season long without having to open it up for any serious maintenance!

If you want us to build your engine, visit the Garage Services tab up at the top of the site, fill out the brief form and we’ll get back to you!  (or just click here: )

  1. Do you think we’ll get to a point where someone makes a re-casted k-series block in the same ilk as the RHS used here? Something that would let you build a very high revving 2.7L perhaps?

    1. There are currently billet K series blocks on the market that can take a lot of power, Drag Cartel has them in the USA.

  2. Awesome informative and techie video, I enjoy all the info stored on Mikes hard drive. These builds definitely separate the men from the boys. Serious components for longevity. Lots to learn here… Thanks for sharing your knowledge and expertise Mike!

    “How much horsepower do you want and for how long?”

  3. Do you think you guys could do like a ‘budget’ LS build; relatively stock power but super reliable? I am building a lot of LS engines for amateur drift guys with very small budgets. Just want to see how you guys would go about it. Ive built 2 so far for under 6k, but have really discounts from the company I work under…starts with a H and ends with a Y. Thank you! say hi to Jon Shaffer for me, we went to high school together!
