Enhanced 602/604

MRE added "enhancing" to the 604 crate engine for IMCA racers in 2017. We did not realize how big of a deal this was going to be at the time. When adding this new product, we were getting more calls asking if we do the 602 as well. So over the course of the racing season, we have developed a 602 program for IMCA racers. Our goal for either engine was to take a racer’s current used up crate engine, freshen it, then enhance it to whatever level the racers budget or local tracks' tech would allow them to do.

We have many levels to choose from and we will provide a few examples below. The biggest downfall to the crate engine is when it’s wore out you have to buy a new one. So, all the money you spend toward a new engine just gets you what you had before, and more than likely, what you had before is why you’re getting beat week after week at your local track. Our goal is to freshen your worn-out engine, enhance it from 20-80 horsepower, and it cost approximately the same as the "new" replacement engine.


50-100 night 602 Crate Engine

  • Freshen and 30 HP gain, approx. $4,000
  • Freshen and 75 HP gain, approx. $5,000-$5,500
  • Freshen and 90 HP gain, approx. $6,000-$6,500
(all these prices include dyno service)

One other option we have for a 602 is this…we can take a brand new engine, and get you a 35 horsepower gain with a dyno session for $2,900. This is a very stealthy operation and would only expect this to pass tech with flying colors. We have new 602 engines in stock to do this too. We also provide a before and after dyno sheet so you can see the results.


50-100 night 604 Crate Engine

  • Freshen and 30 HP gain, approx. $6,000-$6,500
  • Freshen and 60-70 HP gain, approx. $7,000-$7,500
  • Freshen and 100 HP gain, approx. $8,500

What makes this work so well is once you have enhanced the engine, the next time it gets worked on, the price of the next freshen will be cheaper due to already having the “go fast” parts purchased.



We will not put back stock however, we send these engines out the door equipped with a jock strap.
