    Default 3.1 Turbo Grand Prix Mclaren Engine for sale

    3.1 Turbo Grand Prix Mclaren Engine for sale

    Hello,

    I have a 3.1 Turbo Grand Prix engine and Transmission for sale from a 90 . I did a swap into a Fiero a few years ago and now we need to let it go. This engine has a cool history and is very unique. After a few years of driving, it started to smoke so we parked it. It runs and sounds great. Not sure if the turbo seals are leaking or if it has a bad head gasket. Looking to sell the whole car or just the drive train. I have left it stock and have the engine, cooler, computer, trans, and harness. Let me know if you have interest. Can get a lot more power from this motor with a bigger turbo and some tuning. See below.

    Engine Description 3.1L 60 degree V6 Turbocharged
    Horsepower 205@5200
    Torque (ft-lbs) 225@2100
    Top Speed 128 mph
    Max Engine Speed 5500 rpm
    Block Cast Iron
    Heads Aluminum
    Valves 12
    Displacement 3.1L (3100cc, 192ci)
    Cylinders 6, V formation, opposed 60 degrees
    Bore 89mm (3.503")
    Stroke 84mm (3.3122")
    Compression Ratio 8.8:1
    Fuel Management MPFI (Multi Port Fuel Injection). Electronic, controlled by ECM
    Fuel Premium unleaded, 91 pump oct.
    VIN code V
    Usage 1989-90 Grand Prix Turbo, 90 STE Turbo
    Type Gen II - Same motor as 2.8L with an increased stroke


    "Select engine components" meaning they were checked when taken from the parts bin for closer tolerances, that includes some of the engine items listed below:
    Unique Vin V version of the VIN T Block, part number 10140528, stock VIN T Block is part number 10089656. Block, 20% Nickel content to improve strength, very small amount of tin for same.
    (Yet unreleased at that time), head casting 10087511 and its larger, less defined heart shaped combustion chamber, with the deep dished 28cc/ml piston top to achieve the .1 drop in compression ratio to 8.8 (or 8.78 depending on what you read).
    Forged Rods, these forged versions are unique to the 1989-90 TGP and TSTE only, part number 10070113, C-1037 Heat Treated Steel Forging, SAE 1050 Air Quenched Rod Caps.
    Hardened Crank (Nitrided), Nodular Cast Iron with journal camfer/deep rolled fillets, casting 981 but this one IS unique to the 1989-1990 TGP and TSTE, worked on after starting as a 981 crank! Part number 10110549. Ion Nitrided/hardened depth of .02"-.03" raising surface hardness from 30-35 Rockwell C to 60 Rockwell C.
    Mahle Autothermic Hypereutectic Pistons with Reinforcement Bar/Steel Strut to add strength to the top of the piston, 12% Silicone.
    Stock 3.1L cam, as used in the 2.8L, 3.1L Vin T and Vin V.
    Mellings Iron Body High-Volume Oil Pump.
    Engine Oil Cooler as some Monte Z34s had, maybe others, unique water tap to regulate water to turbo, and fittings to plumb it in.
    Coolant line take off welded on to provided for turbo water system return.
    Oil tap port fitting added to block/metal braided hose for feed line to turbo.
    Unique oil pan with turbo oil drain line fitting, and metal hose extension.
    Unique Rear Exhaust Manifold to feed with other Exhaust Manifold the Turbo’s Exhaust/Turbine Side, constructed of cast nodular iron.
    That damn OEM Crossover Pipe.
    Larger 22 lb injectors.
    Upgraded Fuel Pump taken from the Vette Parts Bin.
    Garrett Water Cooled Turbo, T25 though smallish, at least one of the larger versions of it, for less lag problems though all lag is programmed into the chip, unplug the computer from controlling the boost and tire smoke in less than a second, way too much boost/spin to get a good launch, needs a bigger turbo for lag and traction control!
    Boost control solenoid and lines.
    ABS Unit Heat Sheild.
    Unique Fuel Supply/Return Lines/Engine Bay Area, in front of ABS Unit.


    Tranny setup is unique, larger tranny cooling lines and an aux tranny cooler in fender well.
    Hardened Gears and Gear Carrier Set.
    Additional Nested Accumulator Springs, other little changes to the tranny, some not listed until it's taken apart for inspection.
    1898 rpm Stall Converter, not a High-Stall as the stock turbo is not large enough to warrant it!
    Vacuum Line Check Valve/Bleeder at Modulator, Vacuum Line has internal restictor in-line to limit boost pressure and to allow check/bleed to fuction.


    Thanks,
    Curt
