1992 Plymouth Laser RS Turbo - Laser Power

Beware of two things: Kyle Cimbron’s 10-second Laser and sharks with frickin’ laser beams attached to their heads!

“Light Amplification by Stimulated Emission of Radiation” makes for a pretty awesome sounding acronym—laser. Plus, in theory and in science fiction, it makes for a pretty potent weapon. So potent, in fact, that Dr. Evil wanted sharks with frickin’ laser beams attached to their heads. And that’s exactly what he got (although he had to make due with mutated sea bass for a while), along with an ungrateful son and a severe case of male-pattern baldness.

Meanwhile, back at the Chrysler Tower in the late ’80s, Lee Iacocca’s marketing geniuses decided that their version of Mistubishi’s first-generation Eclipse needed a name capable of communicating just how technologically advanced and space-age cool the car really was. And so the Plymouth Laser was born, the top trim level having the added cool factor of both an RS (Rallye Sport) and Turbo (warp speed!) badge. Truth be told, the Laser RS Turbo and its Eagle and Mitsubishi counterparts were incredibly advanced machines at the time, bringing the advantages of turbocharging and AWD to market in a refreshingly sleek and aerodynamic body shape. If you were a car guy in the early ’90s, chances are you wanted one of these little pocket rockets.

Kyle Cimbron, a 26-year-old Rhode Island native, may be too young to have lusted after the Laser when it first came out, but he’s clearly a DSM man through and through, given the number of them he’s owned and the 10-second street beast he’s turned this ’92 RS Turbo into. Sure, he still owns the ’90 Mustang LX 5.0 that was his first car (a project he and his father started when Kyle was just 14), but given his plan to swap a stroked 4G63T into a ’92 Ford Mustang LX as an 8-second drag car project, it’s safe to say he’s a DSMer to the core now.

As Kyle tells us, “I got my start with cars at an early age thanks to my father. We started with the ’90 Mustang I still have today, and I was heavily into Mustangs for a few years, but in New England, we run into snow and tough weather sometimes, so I knew a Mustang was not going to cut it as a daily driver.

We came across a ’90 Talon TSi AWD that had some front end damage [and] looked like a good year-round candidate. I drove that through the winter of my senior year in high school and had a ton of fun with it, researching “free mods” on the Internet and just driving it like a teenager. I sold it after the winter and continued on with Mustangs for a bit, but I always missed the feel of the DSM—tight chassis with good handling and smooth power.”

Kyle then went on a DSM binge of impressive proportions, owning no less than eight—four Eagle Talons, two Galant VR4s, an Eclipse GSX, and a FWD Laser Turbo—but didn’t modify any of them beyond a basic exhaust upgrade. That’s when, in 2005, he came across this Plymouth Laser RS Turbo. As Kyle explains, “I was always a domestic guy, so I thought it was cool too have a Plymouth-badged DSM. When I testdrove the car it had a small, 16g turbo, a boost controller set to 18 psi, and an old five-knob AFC, and it felt like nothing I had driven before. I was hooked. With a stock intercooler and injectors the car ran consistent 13.4- to 13.5-second e.t.’s at 104 mph, and that was where the progression started.”

Once the tuner bug really kicked in, Kyle was running in the 11s down the quarter-mile thanks to larger injectors, a bigger intercooler, a TiAL 38mm wastegate, and DSMLink for tuning. He went through a few turbo upgrades in search of even quicker elapsed times starting with a Buschur 20g and then a twin-scroll 0.70 T4 exhaust housing GT3582R. As Kyle tells us, “That combination never worked that great for me, even though I went 11.0 at 134 mph. It was much laggier then I thought it would be, so I switched to Forced Performance’s FP30 bolt-on Mitsubishi turbine housing and had the compressor housing polished by Jarrod at ShineWorks and started to have more consistency. Plus the engine now made the same power on pump gas as it did on race gas previously. My good friend SteveB deserves a lot of credit on the tune; we spent many nights on the highway to get it where it is today.”

Since then Kyle has focused on slowly improving his Laser’s performance down the strip while maintaining a factory-fresh appearance. According to Kyle, “I try and keep the car as detailed as possible because I know when I go to watch racing, an extremely quick car that is also clean really appeals to me. I have raced the car for eight straight years on the original long-block [only changes being Forced Performance FP4R cams, beehive calve springs, and ARP head studs] and I’ve reached my goals for the car. I wanted a 10-second pass on 17-inch street tires, pump gas, full exhaust, a full interior, and over 3,000 pounds, and I did that last summer at the DSM Shootout [10.95 at 130 mph]. And with 24.5-inch M/T slicks, the car has been as quick as 10.68 at 132 mph.” This may not be quite as quick as a frickin’ laser beam, but we think Dr. Evil would approve.

When I test drove the car it had a small 16g turbo, a boost controller set to 18 psi ,and an old five-knob AFC, and it felt like ...

Unlike Dr. Evil (and his dysfunctional relationship with his son), Kyle credits his father as being the biggest factor in his Laser’s evolution. “We attend all the races together, and the car would not be what it is without him and his help. He is heavily into cars, too, and has a ’68 AMC AMX, a ’79 Porsche 911SC, an ’87 Mustang GT convertible, and a ’69 Chevy C10 that we maintain together.

I also have a great group of friends here locally that we race with (Infamous Performance, SteveB, Victor Teixeira, Brian Cap) who all make doing this fun. Tony Garcia, who does our fabrication work, has also been a major help, along with everyone at NewEngDSM.org.”

Since this feature last year, the car has since gone 10.36@134. Still on the same 136k mile stock motor :-) Thanks for the compliments.

That's quiet hilarious a 40 year old checking out a 18 year old. Creepy. And I'd heard difference from many people so yes... Nice try

My first car ever. 91 turbo. Miss that thing. Since upgraded to an Evo X. The good ol' Laser introduced me to Mitsubishi and haven't looked back

I wish my Laser wasn't a broken heap... Stuff like this makes me want to fix it. Damn rod bearings...
