    Default My 146 Ti turbo from South Africa

    My current Alfa Romeo is a 146 Ti 2.0 Twin Spark with plenty added goodies and magic!
    It has bee turbocharged and intercooled by Alpine Developments South Africa.
    Here is some specs and photos:

    The turbo conversion was done when the car had about 5000 KM on the odo.
    Pistons are standard.
    Conrods are standard but shortened to drop the compression ratio to 8.0:1
    Fuel pressure regulator was bypassed in the tank at the fuel pump and an adjustable fuel pressure regulatorfitted at the rail with a new return pipe to the tank. (done by myself 8))
    2 x Extra fuel injectors for more fuel controlled via a Gotech mini X system.
    The standard Bosch M1.5.5 management remains on the car.
    Boost is set at 0.5 barpressure although this setup can easy handle 0.8 bar. I left it at 0.5 for extra peace of mind!
    Adjustable Koni shocks with a 30mm Eibach drop.
    16" Yokohama A-drive tyres 205/45/16
    Madman EGT gauge installed.
    TIM boost gauge installed
    The standard plastic plenum was replaced with a CF1 Alluminium plenum. The plastic one broke under pressure and led to number 4 piston running lean and breaking a ring landing. This happened to the previous owner.
    Power reading was 141KW on the wheels and 176KW on the flywheel.
    Not bad for a 2.0 4 cylinder! I am in 3.2 V6 territory.....

    The car now has a geniune 74000km on the odo.
    It is a 1999 model.

    Love it, a real street sleeper, if I'm not mistaken 176KW is about 230bhp on old money.
    That should surprise a few people out on the road.

    Anyway, welcome to the forum, and feel free to add the car, and any others you have into the garage.

    Been a while since I was on this forum.
    Turbo I am using is a Mitsubishi TD04H 16T. Normally found on a certain volvo think the 850 T5.

    I've managed to destroy my gearbox.....
    Will post photos on the gearbox change.
    I have a brand new gearbox now.
    fitted it myself.
