I was wondering how hard it would be to swap a 4g63 turbo motor into a '93 scoupe turbo, and what parts beside the motor, tranny, and ecu I would need<img src=icon_smile_big.gif border=0 align=middle>

check out the FAQ about doing the same into a 93-96 Mirage at my site:

www.MirageTuner.com

It should be similar for you guys.

good luck,

It'd be A LOT more work than it's worth.

The '93 Turbo S-Coupe has Hyundai's Alpha I G4EKT motor. Putting a mitsu engine would require total refabrication of motor mounts as they both sit on opposite sides of the car.

You'd be better off working on the G4EKT you have. It's a VERY good motor. By adding a BOV, intercooler, and reprogramming your ECU, 160hp is easily attainable.

hum... well, I can't find any pictures online of a scoupe turbo engine bay to verify it, but I have seen one, and from what I remember, externally is was just like the 4g15, same m ounts and all. why would Hyundai offer two motos the same year with TOTALLY different mounts? That's not good business sense.

where can I find some pics of a turbo engine bay? I think the 4g63t swap is very feasible in any pre 95 excel or scoupe.

I agree it shouldn't be too hard.but your best bet would be to get the whole car.motor mounts and all.that way u have everything u need to do the conversion.y not just keep the car?Your s-coupe would beat that car all day with the same motor point blank.

I'll see if I can find a picture of an S-Coupe Turbo engine bay.

The reason they have two different motors is simple. One is made by Mitsubishi (non-turbo), and one is made by Hyundai (turbo).

In an S-Coupe turbo, you're option for an easy swap is another Hyundai motor, such as the 2.0L Beta. In an S-Coupe non-turbo, you're best option is a 4G6 series motor from Mitsubishi.

even with the two different motors, they should be the same motor mounts (the biggest problem with the swap being mounts), right? I thought the early hyundai motors (alpha) where still based off mitsu motors, and the cases should be the same. If that's the case, no reason it shouldn't work out just as easily.

Nope, the Alpha is 100% Hyundai designed. As for what's different between the engines, the motor mounts are different as Hyundai and Mitsubishi motors are on two different sides of the car.

[s-coupe]

well i'm no mechanic and i have no idea what my mechanic is going to do but i have both cars in my drive way(1992 s-coupe and 1992 eclipse turbo)and when i pop the hoods side by side all the mount seem to line up.the other day he was measuring for the mount and didn't mention anything.now weather he is going to be welding or not i dont know but he said there will be no problem to switch the motors.i have also met someone with a 1993 s-coupe who has already done it the motor is in and he's got over 500hp right this moment.how hard it is i dont know but i know it can be done cause it's been done

 

[4doorGL]

The 1991 and 1992 S-Coupe have a Mitsubishi engine. That I'm sure of. As for the 93-95 S-Coupe, I know for a fact that the turbo S-Coupe has the G4EKT, which is the turbo 1.5L Alpha I motor. As for the 93-95 S-Coupe non-turbo, I'm still trying to find out which motor is in it.

[s-coupe]

well keep checking it out.and let me know but i know for a fact i saw with my own two eyes a 1993 s-coupe with the same 4g63t motor that is going in my 1992 s-coupe.i did not ask if his s-coupe was turbo or not before the swap

 

[blytz]

hum.... is the head then rotated around 180? cuase the Scoupe Turbo (Hyundai motor) exhaust manifold will bolt RIGHT up to the mitsu 1.5l motor.

Both engines in the Series II Scoupe are Hyundai units (alpha). The only difference being that one is Turbocharged and one is not.

Series I Scoupes ('90- '92) had the Mitsu 8v engine.

Heres a couple of diagrams of the series II engine bay that might help:

Good call Pony!

Those are the kinds of pics I was looking for. You'll notice that the tranny is situated on the right side of the engine on the Hyundai motors, while on the Mitsu engines, it's situated on the left.

that engine it the total opposite of my 1992 s-coupe

 

[SuperScoupe]

Does this mean I can just swap the 93 and up turbo scoupe engine in my 93 nonturbo scoupe??? 'Cause the first pick that pony showed was my engine bay man! If you guy's tell me that I can do that swap without too many problems I'll get the biggest boner EVER. Joking<img src=icon_smile_shock.gif border=0 align=middle>

THANKS PONY!!!!!

Okay guys, I'm sorry to have cuased any confusion, I was wrong.... so then, 93+ Scoupes have the engine/tranny rotated...

What about Excels? What year was the last Mitsu engine used? I'm guessing the 94 model has a hyundai engine, and it too is backwards?

thanks,
blytz

 

[blytz]

also, what years were the turbo scoupe made?

just curious, cuz the exhaust manifold WILL bolt up to mitsu 1.5l engines, and they are opposite of the above pictures.

thanks again,
blytz

The Turbo S-Coupe was 93-95.

The Excel never had a Hyundai engine in the U.S. The '95 Accent received the Alpha II motor.

From my researches the Alpha Non-turbo, and Alpha II are much the same. The only thing on the Alpha II is that there are more sensors. I did most of my research on www.hmaservice.com . Countless hours of looking at Engines and comparing them. Damn, My head hurts from that. lol
