First & formost there are TWO distinct S-Coupe`s......The Mk.I car (up to & including `92) & the Mk.II (`93 to `95).
Only the Mk.II was available turbocharged.....with the Garrett T15.

The Mk.I car has a Mitsubishi engine (tranny on left as you face it) & ONLY this car can take other Mitsu. engines!.

The Mk. II car has Hyundai`s own in-house designed Alpha I engine....tranny on right.
The later `95 models featured modern distributor-less ignition with twin wasted-spark coil packs.

Any T2 Series Garrett turbocharger (T20/T25/T28) will bolt up & replace the turbo on the S-Coupe Turbo model, BUT, because of the flange & internal porting, it MUST have a stock Garrett flange OR be ex-Nissan............Mitsu/DSM flanges are NOT suitable & WON`T fit!.

Here is a photo of the S-Coupe Turbo`s stock Garrett T15 turbocharger which clearly shows it`s manifold mounting flange :-

Cheers,
Nick. :)

Exellent info! Thanks!

Mmmmm Turbo......the reason I bought the car.

in europe(at least holland, de mk2 was available from '92 until '96 and the gt turbo from '93-'94

can you tell me the weight of the standard Scoupe SE (non-turbo) 1995?

and the stock BHP?

trying to work out bhp/tonne :)

cheers.

Oz.

i find tht wierd about the model years cause several scoue gt turbo's i could had bought were from '92 also, but if im right they were some kind of "special" edition or something!

Nick, interesting post. I have a '91 Scoupe, and need to do an engine change. Do you have any specifics on what Mitsu motors will fit such as Eclipse? Transmission also(prefer auto). How about axles,wiring fuel,etc. Any insight greatly appreciated.:-)

The only engines that fit that I know of are the 4G63T and the 4G63 N/A. These engines generally come from the EVO, eclipse, and eagle talon. I've seen a guy on cardomain who claimed to have put in a 6G72TT engine from a 3000GT VR4 but that would take a lot of work.

The weight of a '95 N/A scoupe is 943 kg.

Stock b.h.p. of the n.a. car is 90.

Here is some more info on the Scoupe.


"Hyundai Motor America is trying to pump up its image with an all-new Hyundai-designed and -developed engine.

The Alpha (G4EK), Hyundai's first internally developed engine, powers the new '93 Scoupe, which reaches dealer showrooms in October. The 1.5L (1,495-cc) 4-cyl. engine has a 75.5-mm bore and an 83.5-mm stroke, It is a single-overhead-cam 12valve (two intake and one exhaust valve per cylinder) engine with multipoint fuel injection and is available in either naturally aspirated or turbocharged form.

The naturally aspirated engine produces 92 hp at 5,500 rpm and 97 ft.-lbs. (131.5 Nm) of peak torque at 4,000 rpm using a 10:1 compression ratio, while the turbocharged version kicks out 115 hp at 5,500 rpm and 123 ft.-lbs. (167 Nm) of torque at 4,500'rpm with a 7.5:1 compression ratio. Hyundai says the Scoupe is the first production application for Garrett Automotive Products' new model T15 turbocharger. The turbo unit includes water-cooled bearings and housings and an integral wastegate.

The naturally aspirated Alpha boasts a 14% increase in power over its 1.5L Mitsubishi-designed predecessor, and the turbo produces 42% more horsepower.


South Korea's first domestically designed engine features a cast-iron block and crankshaft. an aluminum head, aluminum pistons and steel connecting rods. A special compact pentroof combustion chamber design with central spark plug location has been incorporated to optimize engine efficiency. The engine utilizes a Robert Bosch GmbH electronic engine control system and a knock sensor.

The Alpha engine, the product of six years of study at Hyundai's Mobookri Engineering Research & Development Center outside of Seoul, is produced in Ulsan. Alpha capacity is 100,000 engines annually.

The '93 Scoupe also offers two new transmissions. First is a 5-speed manual that employs cable-type shift linkage and a hydraulic clutch. Final-drive ratio is 3.842 when mated to the naturally aspirated engine and 3.650 when teamed with the blown engine. Fifth gear ratios are 0.838 and 0.878, respectively.

There's al so a new 4-speed electronically controlled automatic transmission with lock-up torque converter. The automatic transmission is only available in combination with the naturally aspirated Alpha engine. Final-drive ratio is 4.029 and fourth-gear ratio is 0.685.

The Scoupe also gets a facelift for '93 with new hood and front-fender sheet metal. from-bumper fascia with body-color air inlet, a rear spoiler, new wheel covers and up-level alloy wheels. Prices remain nearly unchanged. The base Scoupe lists al $8,999. and the new Turbo Scoupe is expected to sell for under $11.000.

In 1997, the Scoupe is to be replaced by the HCD-2. Much like the HCD-I sports car that bowed at the Detroit International Auto Show in January, the HCD-2 offers different rear and front fenders. Targeted to compete with Mazda Miata, it is still unknown whether the HCD-2 will be a 2-or 4-seater, says Dal Ok Chung, Hyundai Motor America president and chief executive officer. He adds that the production site could be the Bromont plant."

Okay here goes.....Engines that theoretically fit can fit in a 1st gen scoupe:
all engines that 4g6X, 4g9X, 4g1X 4g3x with swapping around mounts trannys, cv axels,ecu's,wiring harness or such from various other cars. also if you want to use older g63's,g32b's,g37's, they should theoretically work too. a g54b will not work as the engine was designed at least in the usa for rwd applications only. I've seen 1 6g72 swapped in a c50 colt (closely related as the scoupe is based on the earlier c10), but the guy for some reason welded the front clip from a galant(retarded), and put it in the galant engine bay. You can make just as much power with a 4g63t as a 6g72 and you'll have more after market support. A 6g72 is just for the WOW factor, wow you have a twin turbo v6....neato. Although a 6g72 can theoretically fit as the engine is the same width as a 4g63 and the awd tranny is the same (w5m33, with different bell housing). the engine is a heavy f-ing beast and would make the thing handle like poo. Also a 4g63t can make more power with less money. Why not get a gto/3000gt/stealth and have better handling, if your looking for the bling factor? If you have a mitsu question just go to 4g61t.com and newbie forum and plug away.
