Thanks Dave, here we call this Omega platform. There are variations of Omega around here for the motorization and optional comfort. However the Omega was produced in Brazil between 1992 and 1998 in versions 4 and 6 cylinders with manual and automatic transmission. The most powerful were the 6 cylinders 4100cc followed by the 3000cc. The engine L6 4100 had improvements in the gas admission with a multipoint injection system, however, the programmable ECU, explore a little more this engine. In Brazil this car was only sold with an 8v head. I'm now posting some more photos so the OOF's can see and comment. my project is simple and predicts something around 400whp. here in Brazil there are many performance parts for the L6 engine.

Photos do not follow chronological order. They are just to demonstrate some details of my project. Hope you like it.
In photos you can see the changes of battery position, ABS and hydraulic steering system. Some air conditioning hoses have been altered as well. the turbo assembly lasted almost 4 months and cost approximately $ 4,000.00. Around here, a well-maintained Omega costs around $ 5,000. The biggest problem of Omega are the "accessories". There are no OEM parts like taillights, headlight, blinks, sidebars, spoilers and so on. A well maintained instrument panel is difficult to find as well.
