1991 Mitsubishi Eclipse GSX – Stock-Block Rock Star


The first The Fast along with the Furious film made building a 10-second car seem pretty straightforward: Do some illegal street racing, wear a dirty tank top, have a backyard barbecue then an all-nighter in the garage, and bada bing bada boom, 10-second car complete. If you’re aiming to do it without having a Hollywood bankroll, but if you’ve ever actually tried to go this fast in the quarter-mile, you know it’s not that simple, especially.

For Fernando Martinez and his Florida-based shop, Ostar Motorsports, the objective wasn’t only to build a fast car with limited funds, though that’s certainly an ambition many of us can relate to. He also needed a store car to help you promote his company and carve out a niche within the ultracompetitive realm of high-performance tuning. Little did he understand that these humble beginnings would lead to one hell of the drag racing adventure as well as awas really a kid, having grown up using a gearhead for any father. I remember my dad tinkering with his ’69 Charger 440, and I was amazed at how powerful the engine sounded. It was music to my ears, and it was then that my passion for cars really took flight. I joined the military after high school and bought my first car, a ’91 Honda CRX. From there I moved on to your ’99 Civic Si or even a ’98 Eclipse GST. This list goes on and on from an Integra Type R to an SC300 with a 2JZ swap.

Using a car resume like that, it shouldn’t surprise you too much that in 2007, Fernando decided to open his own performance shop using a partner. Unfortunately, that partnership didn’t exercise, so he had to start from scratch in 2009, founding Ostar Motorsports being a home-based, business online. As Fernando told us, After I started Ostar, I had a little left to get a car to help promote the business. By little money, I mean $5K, which really limited my choices. So I considered to myself, What type of car can I make fast with little money? And that’s once i decided a DSM will be perfect.

While browsing the web for a suitable candidate, he came across this ’91 Eclipse GSX just a few hours drive from Orlando. I called my good friend and DSM guru Armando Miro and told him about my find, as Fernando explained. He said he knew the auto and that it must be a good buy to have some fun with. So, we ended up making the trip, and when I saw the auto, I knew it would be coming home with me. It had been a perfect fit for what money I had as well as the goals we had under considerationAs you’d expect for a cheerful and cheap 1g Eclipse, it was equipped with an internally stock engine, so the initial build was kept simple, resulting in 400 whp. We hit the track every weekend, and the car performed like a champ. So we went with a 67mm turbo and a few supporting mods that, in your eyes, were overkill for that stock motor but would work on the car once we had enough money to build the base end, even though pretty soon 400 whp just wasn’t enough. We ended up tuning the car with this new setup and we went for broke. The car made 650 whp, and at that point, we did not think it might hold up long, but we took our chances and hit the track anyway. We went from 10.9 to 10.5 to 10. in a matter of months. This was super exciting for people like us, and the car was a huge success at each and every track event we would visit. People throughout the net loved the car and what we were doing. Would you have thought that a stock bottom DSM would be able to take so much punishment and keep going and going? Fernando says.

Astonished by the e and reliability.t.’s they’d achieved so far, Fernando and Armando Danny Garcia, and Manual Aponte (CMB Tuning) decided they should just keep pushing the envelope to see where it took them. This is the time they realized they might even have a shot at beating the stock-block DSM record they kept reading about in the forums. According to Fernando, We ended up hitting some bumps in the road, but luckily we had some good friends like Mike Rizzotti and John Shepherd who helped us sort out a misfire which had haunted us for months so we could finally hit the 9-second range and take the record for fastest stock bottom 4G63. Not Fernando and his team, although a lot of crews would have kicked back, cracked open a few beers, and let the Internet glory roll in: After breaking the record, we thought, Why stop now? So we pushed the car even harder and managed to extract a whopping 755 whp. We went straight back to the track and been able to run a 9.22 at 154 mph. What a night! We could not believe what we should had just done. It had been such feeling of accomplishment which i cannot even explain it in words. Not much longer after that, I made the decision to take a different route for your next season, and since we accomplished beating the record, we finally decided for that new season to actually build an engine, and that is precisely what is currently in the works.

Look for Ostar’s record-setting Eclipse around this year’s DSM/Evo Shootout as well as Imports versus Domestics in Maryland, the 2 events Fernando and his team have targeted once their new high-compression 42R one thousand-plus-whp engine is ready for battle. The big boys of the DSM drag world better bring their A-game to stay in front of the stock-block rock stars from Ostar if their history so far is any indication.
