Best of Both Worlds v8rx7guy#8217;s LS1 Swapped 1993 RX-7

V8rx7guy#39;s obsession V8 engines started about 10 ago while he was still in high At the time, Matt K. was driving a V6 MX-3 which he thought was one of the cars in his school. It wasn#39;t the day he tested its acceleration against a Foxbody Mustang that he that it was time for a different

Even though he knew a large engine in a small car was the he had a hard time finding the car. All of the cars I looked at had V8#39;s that I could were always too heavy, not on the outside, or really only well in a straight line, says. In his opinion, there too many sacrifices when it to domestic cars and he really something that could well and still being in a straight line.

Matt#39;s began in the Japanese import and he knew he wanted to keep it way. He began researching cars from Japan with V8#39;s and as most of us there aren#39;t many While searching, he stumbled RX-7 owners who had swapped out the rotary engine in favor of an V8.

This piqued his interest and he had always been a fan of Mazda, he no time finding an FC RX-7 to build. While the shell particularly clean, he was a poor school student who was about to a poor college student so it bother him too much. Matt up swapping an LT1 out of an early 90#39;s and drove the car all the way through college.

finishing his degree in Mechanical and landing his first job, he this 1993 RX-7. An FD had Matt#39;s dream car for many and he wanted to take everything he from his previous RX-7 and it to a newer and nicer chassis. The thing he did was source an engine and from a 2002 Pontiac The LS1 and T56 (6 speed transmission) was superior to his car#39;s LT1 in many ways but importantly it was lighter.

He knew that LS1 engines aluminum which meant there would be a minimal increase (if any at all) over the dressed turbo rotary.

has owned his RX-7 for 5 years and it has through multiple iterations and My philosophy on building cars is to set goals, modify to meet goals, and to enjoy the car while feedback from how it behaves and a new set of goals, he says. Every Matt sets a new goal for the car takes it to the next level. He that if he sets too lofty of at one time, the car will do nothing but sit on stands.

By setting realistic and not trying to do too much all at once, he gets to enjoy his car when rolls around. Last I met my goals of reaching 10#39;s in the mile and competing in a handful of events. This year, I am my focus to AutoX as I feel I reached a level in drag where I will have to comprimises to my car to go any faster, Matt

You may notice that Matt#39;s is a slightly different yellow other RX-7#39;s you#39;ve When Matt was choosing a new to paint his car (the car had already painted yellow by a previous he went through 10-12 samples from various before finally deciding on Bathurst Yellow. This is the same color as Special RX-7#39;s from the last of production in Japan.

When I Matt what his favorite mod is, it was a decision for him. He finally I think that my favorite besides the LS1/T56 swap of is probably the roll bar. The bar was a requirement when I started below 11.50 in the quarter

I actually designed and fabricated the bar myself which was a challenge for me. One of the features about the roll bar is even though it is welded in, I was to design it to be moved in and out of the car throughout This allowed me to do all the important outside the vehicle and even it off for powder coating before it into place.

A well-built bar that doesn#39;t interfere daily driving is not an easy but I think it turned out really and I get lots of compliments.

One of the more questions that sometimes asked at car shows or drag events is: Why would you replace the with an American V8?

His response: I why people feel that the engine is unique to the car, but might just be the only argument. If people can get around they find that an LS1 not add any weight or ruin the weight It is significantly more reliable, it has horsepower potential, and gets better fuel economy.

In my opinion, there really is a big in behavior between a high-sprung car that makes it#39;s up high (not just but in general) and a mildly built N/A LS1 can easily produce 450 RWHP and 380 ft-lb of torque through the whole range of RPMs. It may not be a queen of an engine at that (though it is plenty capable if you to go down that path), but the low end and reliability allows the car to be competitive in any of racing event you throw at it.

estimates that with his cam swap and other mods his car is around 450 HP. He plans on having the car in the near future and it should be more power. His fastest mile time is a 10.94 at 129 MPH a 1.64 60#39;.
