On the Superchips web-pages, upgrade the Hyundai Scoupe turbo with EEPROM plus high boost from 8-9 PSI stock to 14 PSI, plus intake air cool induction with a result of over 150 HP... 0-100 in less 6.9 seconds.

I also have a '93 S-coupe Turbo and I am looking to stick a Garret t3 turbo on it. But I am having trouble finding a turbo manifold to fit it. If anyone has any clues as to where I could find one to work, please e-mail me at: DRMANGL303@AOL.COM

Thank you.

I've got a 95 Scoupe MVTI turbo. What's the difference between the GT-i and MVTI?

In mine I've embarrassed some big cars with its great, free revving, little motor.

Not the most comfortable, but hey I didn't buy it for that. I bought it to be different.

Hi, I also have SCoupe Turbo GT, and I've fill it with intercooler from "VW Lupo", and big Sports Air Filter "KingDragon". I'm wondering if you could tell me how to get this 165hp. My E-Mail is LWBZIK@POCZTA.ONET.PL.

Hi! I have a Hyundai Scoupe Turbo too. Its engine is a 1.5L SOHC that reached 230 bhp on the "dyno".

You need money to make your Scoupe reach this HP. In its engine I have installed a T3/TO4 hybrid turbine at 21psi using original pistons and no modification to the head block. Also it has an MSD (multiple spark discharger), a fuel pressure regulator, a ram air connected to the turbine intake, a racing fuel pump, Grand National injectors, a HKS valve, an intercooler, a Turbonetics delta gate, header, an Elantra flow meter, and an APEX'i computer to change the settings.

In the transmission, I have installed a racing clutch. With 17" tires it does 13.5 sec. in a 1/4 mile, and with slick tires, 12.4 sec. in a 1/4 mile.

Hi, I am thinking of buying an Scoupe Turbo!

With a front mounted intercooler, a new exhaust from the turbine and back with a diameter of 55mm-60mm, a T2 or T2.5 turbine and a new program chip, which sends the pressure to 1-1.2 bar, the car surely reaches 210bhp.

If anyone has photos of a 1.5 litre turbo engine or diagrams of this motor, please email me at salabren@yahoo.gr

I would like EDGAR DIAZ to send me his email so I can find out what I need to do to get my Scoupe GT to replicate his.

My email address is silloc@caribsurf.com.
