The next generation of Mitsubishi 4 cylinder engines where based on the same blocks as the G62B/G63B. The 4G63 was introduced in the Japanese market Galant and came in naturally aspirated and turbocharged intercooled variants. The 4G63 variant is a 1997 cc 2.0L engine (85 mm bore x 88 mm stroke) and came in SOHC and DOHC version. The 4G63T is found in various models including the 1988-92 Galant VR-4, the 1990-1999 Eclipse, and the Lancer Evolution I-IX available in a variety of specs.


Mitsubishi has mainly been associated in the rally and road race sport, but in the last 15 years the 4G63T engine has played a huge role in Mitsubishi powered drag vehicles.

We can't start the Mitsubishi drag history without mentioning Puerto Rico's Sakura Racing. Puerto Rico has a history of pioneering import drag racing in the mid-'70s and -'80s, and it is still a huge sport in the island. Although Sakura didn't raced with a 4G63T engine, Eric Yamil Torres and Sakura Racing are well known as one of the Mitsubishi drag racing pioneers. Sakura started racing in a starion powered 4G54 Colt. The Colt was later retired and Sakura came back strong with a '95 Mirage full-tube chassis with the same 4G54 Colt engine and became one of the top contenders in the sport. In July 20, 1997 at the 4th annual Pan American Nationals PR vs USA at Atco Raceway in New Jersey Sakura became the 1st 4cyl import (Japanese) doorslammer to break the 7sec barrier with an ET of 7.97 @ 168 mph. In April 12, 2000 at the Caribbean Raceway Park in Puerto Rico Sakura broke the 4cyl import record with an ET of 7.52 @ 175 mph and two weeks later in April 30 at Ponce International Speedway Park in Puerto Rico Sakura improved its existing World Record with an earth shattering 7.48 @ 176 mph. Sakura later on retired its Starion powered 4cyl engine and swap in a 6G74 V6 engine with intentions of been more competitive with the bigger 6cyl import drag cars, but Sakura never had the chance to release the beast to the wild and currently the World 1st 7sec 4cyl import doorslammer is for SALE.


1990 - 1994

David Buschur the DSM pioneer had just traded his 1985 Monte Carlo SS for a black 1990 AWD Eagle Talon. This little turbo 4cyl. went 15.11 in stock form. Late fall of 1991 David Buschur bought the car most people know about. The black cherry 1991 Eagle Talon which became known as "4Bangr". This car is what got the parts flowing. The 4Bangr Talon ran a 13.48 @ 98 mph the first time to the track and a in 1993 David Buschur's '91 AWD Talon became the 1st DSM to break the 12sec barrier. Dave's best time that year was 12.34 @ 116.72 mph. In July 1994, Dave's Talon was the 2nd DSM to join the 11sec club and 1st non-nitrous DSM 11sec car with an ET 11.98 @ 116.36 mph.


reg DiRocco was the 1st DSM to break the 11sec barrier.

Buschur's 1st DSM Shootout took place at 1993 with just 8 DSMs. The '94 Buschur DSM Shootout had just 19 cars and the '95 Buschur DSM Shootout turned out GREAT with 47 cars, 25 AWDs, 15 FWDs, 2 Galants, 2 non-turbos, and 3 non-dsm cars. Buschur ran an incredible 11.37 @ 124 mph with a 50-shot nitrous system. Greg ran a 11.61 also under nitrous.

Sean Glazar '92 Talon TSI was the 1st DSM to break the 130 mph barrier 10.922 @ 130.97 9/06/97.

Tym Switzer '91 Talon TSI 1st DSM to break the 10sec barrier


Jack Culotta's '90 Eclipse GSX ran a similar combination to Sean Glazar's Talon, a fairly stock block, a hand ported head, a 20G hybrid set up at 25psi. Jack planned in running a new combination the next year and join the prestigious 10sec DSM club only Sean Glazar and Tym Switzer where part of at the time.

By 1998 the shootout was entering it's 8th year. David Sold the 4Bangr to John Shepherd and started a project most people "laughed" at. He was going to build the ultimate DSM, a DSM that would no longer break driveline parts. He back halfed a '92 Talon and converted it RWD, installed a Chevy 12 bolt rear end and a powerglide transmission. The car made a few test runs right before the 1998 Shootout. It ran a best of mid 11's. The following day at the Import Race held at Norwalk Raceway Park David Buschur's '92 RWD Talon became the World Quickest DSM back to back 10.60's and gave DSM'ers something to be proud of. David Buschur's '92 RWD Talon ran 9.61 at 141.86 mph becoming the 1st DSM to break the 9sec barrier.


Sean Glazar owner of Extreme Motorsports is no stranger to the dragstrip and has been racing since 1995. Sean's NHRA Quick Class '92 AWD 2,900-pound Talon "White Lightning" forced fed by a Garrett T04 turbo prepared by Turbo Engineering Corporation that reaped the benefits of a Spearco water-to-air intercooler and controlled by a PMS EFI system. To grip the road, Sean ran 15x8 Bogart wheels and M&H slicks. Its best ET at the time was 10.66 @ 128 mph.


John Shepherd had two DSMs at the time. John's purchase Buschur's '91 black cherry Talon, now the infamous Shep 7sec AWD Talon as we know it these days. A proven 20G turbo feed a Buschur air-to-air intercooler to a Buschur sheetmetal intake manifold. Boost pressure was set at 25psi and Volk Racing TE37 wheels with Nitto NT-555R drag radials tranfered the power to the track. Shep's Best ET was 10.72 @ 131.02 mph. John's flame red '92 Talon retained its daily-driven characteristics. The car still ran its A/C, cruise control, and power steering along with full interior and upgraded stereo system. The car's engine was similar to his '91 Talon set-up, with a few minor exceptions. A 20G turbo at 26psi and 17x6.5 in. Konig wheels and Nitto NT-555R 225/50R-17 drag radials. Its best ET at the time was 10.95 @ 125.74 mph.


Brent Rau had bought a brand new '95 Eclipse GSX as a daily driver vehicle for his wife and it didn't stayed daily for long. Brent soon found out the next following year it would make a good race car, at which point it became a track only car. Brent raced the car through the '98 season with full interior and power steering, weighting 3,150 lbs. His best ET at the time was 11.11 @ 123.38 mph.



David Buschur sold his RWD Outlaw class Talon at the end of 1999 and started a 2G tube chassis.

Sean Glazar AWD Talon went thru some changes. A new paint scheme, drop the weight to 2,755 lbs and made a few changes to the engine internals, changed to an air-to-air intercooler and Haltech ECU and squeezed 663 whp & 617wtq @ 30psi & 100-nitrous shot, but still had its OEM dash, center console, and carpet maintaining the factory interior look. Sean's Talon made a lot off progress that year.


Early '99 Brent Rau decided to get serious in his quest for bragging authority and made some serious irreversible changes. The Eclipse went thru a weight loss diet now at 2,740lbs, a turbo upgrade , a Haltech ECU now controlled the engine. Brent's first race in 1999 was at the Diamond Star Shootout, which he won with a 10.57 @ 131 mph. At his second race of the season at a track near Farmington, Minnesota he scored another 1st place win with a 10.41 @ 138 mph ET with the help of a 50-shot nitrous system. Brent upgraded the nitrous system dial-in to a 100-shot and 657whp. At the Battle of the Imports Sept 17-18 Brent qualified 3rd with an ET 10.10 @ 147 mph and won the finals against Ed Bergenholtz's CRX with an ET 9.74 @ 146 mph becoming the Quickest Quick Class DSM at the time.

When Eric Plebani's 4G63 powered '87 Starion first graced back in '99 it was a fast, budget-conscious Diamond Star. Plebani's Starion debuted May 15th, 1999 at Island Dragway in New Jersey and ran consistent 11.5s at 124 mph, which was enough to be considered a very worthy Starion. Back then, the Diamond Star was equipped with a bone-stock 4G63 Eclipse powerplant plugged into a bone stock OEM Starion transmission. Plebani swapped out the 20G turbo for a larger T-66 Innovative turbo. The new hair dryer was set for 27-psi of boost pressure, just like the original. Soon after, a Chevy Powerglide was poised and upraded the rear end with a lower gear ratio. In just under a year, Plebani was able to move up the ladder from double to single digits. The Screamin' Starion grasped 9.73 at 141 mph at the '00 DSM Shootout. Plebani ran a personal best of 9.54 @ 144 at the IDRC Maple Grove event August 12, 2000.


When eyes where first laid on Sean Glazar's new 2000 Mirage race car, there where two quick impressions. The first had to do with the immaculate build quality of the vehicle and the second was, where's the Talon? The Mirage was powered by a Turbonetics T-Series turbo set at 30psi and a two-stage, single-nozzle nitrous system from Nitrous Express. The first stage jetted 50hp and, when activated, stage two added an additional 50 stampeding ponies to the mix. Like the Talon, engine management chores are handled by a Haltech system. The Talon ran an E6S-8 and the Mirage runs on an E6K. After playing with the program for a while, Sean's Mirage ended up with 603.4 hp and 513.4 ft-lbs. The traction equation greatly changed from all-wheel drive to front-wheel drive. The slicks are 8.7x25x13s mounted to 13x8 Bogart Racing Pro 4 wheels while the rear consists of skinnies-15x3.5 Bogeys and 2x24x15 rubber. The 4G63 made its debut at the Virginia Battle Of The Imports. At its first event and its sixth pass ever, the Mirage boosted its way into the 9-second club with a 9.95 at 150.30 mph. Problems with the 1st gear synchros had forced Glazar to launch in second gear. That's right, the Mirage ran a 9-second ET while launching in second gear. The Mirage was tweaked for more power and the crew set off for the IDRC event at Englishtown. Right out of the box, the Mirage screamed to a 9.73 at 152 mph.


At Oct 1 at the Route 66 Battle of the Imports in Joliet, Illinois, Sean Glazar brought back his Talon and clicked off insane numbers after 10 months of down time blasting a 9.22 @ 153 mph and winning the Quick Class finals.



The 1998 Eagle Talon tube chassis car was finished by Gary Reese chassis in the early spring of 2001. The first time at the track the car ran a 9.0 on a partial pass. David Buschur's 98 RWD Talon became the 1st DSM to break the 8sec barrier. They ran a best of 8.04 at 172.8 mph the first year with the car.


Sean Glazar was fighting to become the NHRA Quick Class "Top Dog" since day one. The NHRA Quick Class was the most competitive class of racing at the time. Becoming the "Top Dog" wasn't an easy task. Sean's Talon underwent a diet and a turbo upgrade generated nearly 800 hp at the wheels. Due to the different regulations between drag racing sanctioning bodies, Glazar has to alter the weight of the Talon by as much as 200 lbs between races (NIRA: 2,330 lbs vs. IDRC: 2535 lbs.). At the IDRC Maple Grove event on October 21, 2001, Sean tore off a scorching 8.875-sec. at 153.85 mph during competition, making it the first ever 8-second pass by a Quick Class car. Prior to the mind blowing run, Glazar already set the pace with a 9.02, 9.04 and 9.08 run on the quarter. When Sean ran its 8.875, it was still at a heavy 2535. At the IDRC Nationals Quick Class finals at Moroso Raceway Park in Florida, Sean blistered a 9.28 @ 155 mph against Mike Crawford's FWD Neon 9.72 @ 133 mph taking the win.

Len Monserrat's Outlaw Class AWD Eclipse was featured as a 10-second racer earlier this year but at the IDRC Nationals at Moroso Raceway Park in Florida Len ran a personal best of 9.37.

Nov 11 at the IDRC Long Horn Nationals semi-finals in San Antonio, TX, John Shepherd looking to increase his IDRC Street Class points lead blasted a personal record ET 9.898 at 147 mph on drag radials . Shep won 8 IDRC events that year and became the IDRC Street Class champ.


In July 4th weekend David Buschur's '98 RWD Talon ran 7.81 at 175 mph becoming the 1st DSM to break the 7sec barrier at the IDRC Summer Slam Nationals at Englishtown, New Jersey .

Brent Rau debuted the '99 RWD Eclipse at Atco Raceway August 02. The first pass off the trailer was riddle with suspense and ran a low 10sec pass. However, the car steadily improved at the semi-finals with an impressive 8.63 @ 156 mph, but was outran. Since then, Brent and his team kept pushing the car harder during the season yielding a best ET of 7.98 @ 168 mph during a Battle of the Imports race. With just 9 passes in the season it was clear Brent's Pro Outlaw Eclipse was going places.



Brent Rau's Eclipse became the first NDRA Pro Outlaw rear-driver to make it into the 7s (7.96 at 172.36 mph)

Early 2003 Buschur built a RWD Conquest. This is a gorgeous car. Kevin Lawson, a very good friend of Dave had the duties to pilot the car. With just a 10″ tire, no wheel tubs, power windows, carpet, all functioning lights and a sunroof the car ran a best of 8.61 at 158 mph.


In July David Buschur was at Englishtown, NJ racing his tube chassis Talon and ended up crashing it against the wall at 150mph. Buschur fixed the Talon, but as 2005 it hasn't been ran again.


John Shepherd joined the 8sec club at Oct 5 with an impressive 8.76 @ 165 mph.

Automotosports (AMS Performance) employees campaigned three street class cars in Nopi's NDRA race series. It was a rough first year as they were running against the Efantis and Titan race proven Toyota Supras. AMS was definitely out classed but made 90% of the events that year. It was a good learning experience for them as it was the first national racing circuit they attempted to compete in. 2003 was also the year the Mitsubishi Evolution VIII arrived. AMS was the first in the area to have one and immediately started work on improving the already potent platform. In mid 2003, AMS had already begun the development of the Evo 8 T3/T4 kit. The tubular header design was optimized and a lot of time was spent perfecting the ultimate combination of turbine and compressor sizes for the turbo kit. AMS was looking for the most power without compromising spool-up time. Twelve different combinations netted what has become the most popular spec'd GT35RLS found in most 4G63 applications for years to come.


Curt Brown became the world quickest non-nitrous DSM with a ET 9.41 @ 146 mph

Russ Coxe VRC Racing '95 Eclipse GSX became the 1st automatic DSM to join the 9sec club with an ET 9.70 @ 139mph.

Dale Nardozzi became the world quickest Galant VR4 10.27 @ 132 mph.

In the fall Tim Salefski piloted the AMS Evo to a full weight Evo record of 10.53 @ 137 mph.

Robert Barac '94 Evolution III ran a full interior, full exhaust and BFGoodrich street tires, and Garrett GT35R turbo 1.06 A/R on the turbine side & .70 A/R compressor @ 35psi controlled by a Haltech EGK engine management system generating 589whp and a best ET 9.97 @ 145 mph at Willowbank Raceway in Queensland .



In Oct 16 at the NDRA Finals at Norwalk Raceway Brent Rau in his Osofaast Racing Eclipse ran a 7.0 in the first round and then a unreal 6.97 @ 198mph. Brent Rau took the Pro Outlaw RWD win, became the 1st Pro Outlaw car to break the 6sec barrier and the world quickest 4 cylinder.


In Oct 2 at the NHRA Fall National at Old Bridgetown Raceway John Shepherd ran an impressive 7.97 @ 179 mph and made history becoming the world 1st 4cyl AWD and 2nd AWD ever to join the 7sec club.

At the end of the 2004 season AMS converted the Drag Evo 8 into a Road Racing Evo, still kept drag racing and in September the AMS shattered the long standing ¼ mile record for an Evo 8 by running a 9.41 @ 150 mph.


At the DSM Shootout Shep ran an impressive 7.95 @ 182 mph without nitrous becoming the quickest non-nitrous DSM. In Nov 5 at the World Cup Finals Imports vs Domestic at Maryland International Dragway Shep ran a personal best ET 7.70 @ 191 mph, a record that still stands as the world quickest Mitsubishi AWD.

Marco Passante of Magnus Motorsports blew away the Quick 16 competition at the DSM Shootout with numerous 8-second runs taking the class win. His best ET at the Shootout [email protected]


AMS continued to run quicker times in the Drag Evo 8 working down to A 8.97 @ 165 mph.

Im sure a lot of people will knock on DSMs as themselves will have rod knock. A lot of kids get these cars and just do the stupidest shit to them. Ruin them. Make them look bad. Act like dopes. I dont have to mention the movies. But there are actual great DSMs out there. Legit ones built right that make power and look like sex. Im trying to go down that road. I dont buy the cheap shit that just makes my car work and then go beat the shit out of it, break down in front of everyone and make an ass of myself. There are guys out there that drive these cars right. And when they are, I believe theyre pretty fucking sexy. And honestly they should be slightly not so much feared, but cause a concern when theyre built right and ready to race. Because they can perform great numbers for only a 4 cylinder.
