    Although it is not the 1.4 litre it is in the ecotec family... the 2.2 litre that was in the cavalier was modified by a gm performance team to put out over 1000 horsepower. If I remember right it put out close to 500 on stock internals. It just goes to show how much potential there is out of these motors. Mind you the 2.2 litres that GM modified was gigantic by the time it was done.

    the problem with the 1.4L engine is that the turbo is so freaking small. IMO at 200whp and over you are flowing well beyond efficiency of the turbo. But to verify that you'll need the turbo map spec sheet.

    I think on a stock turbo you should look at 200whp as a goal. Go over, look at a turbo upgrade.

    but when you upgrade, you got to get a new exhaust manifold, as they are a one piece design

    That part of GM Performance was actually Roush Racing in Livonia Mi. With the 2.0 Ecotec they made a hair over 1500 bhp, pushing about 60 pound of boost on methonal revving 10,000 rpm.

    I understand everyone here is arguing soley on possibilities of the motor and not the wisdom of the application to the Cruze. But it still must be said just incase. The Cruze is not the prefered platform of choice for high power high performance. But like said before with $X not being a factor then Y_Performance is always possible.

    Thats the one!!! I couldn't quite remember the details. It just goes to show how much power can be pushed out of a tiny motor!!

    Yeah but how long will it last? At over 10,000 rpm its no longer a street car engine but a race engine and they swap those out each race. It's longevity is measured in hours not 10s of thousands of miles.

    Actually they did quite a bit to ensure it could handle the stresses and last. That is why it ended up being twice its original size. I found the website => GMTunerSource.com - ECOtec Drag Engine Specs. Its the equivalent of a 350 V8 putting out over 4000 hp.


    Engine Type: Inline 4-cylinder
    Displacement: 2.16 Liters
    Bore x Stroke: 89mm x 89 mm (destroked for high RPM operation) Valves/cylinder: 4
    Balance Shafts: Removed for high RPM operation
    Block: Aluminum (lost foam cast) with steel cylinder liners
    Head: Aluminum (sand cast) with custom race porting
    Crankshaft: 3.505 Billet Steel
    Rods: Manley I-beam, 300M material
    Pistons: JE aluminum with 22mm PPP Pins
    Compression: 10.8:1
    Camshafts: Comp Cams billet custom ground, with roller finger followers
    Induction: Borg Warner S400 Turbocharger w/ air to water intercooler
    Ignition: Capacitive discharge by MSD
    Fuel Delivery: 3 injectors per cylinder with FAST XFI controller
    Fuel: Methanol
    Lubrication: Dry sump
    Exhaust: 4 into 1, custom bent
    Horsepower: 1450hp @ 9200rpm
    Torque: 940 lb-ft @ 7700rpm


    Anyways this is an extreme but my original point was they obtained in the area of 500 hp off of a stock motor with no modifications to the block or head.

    The value of maximum RPM doesn't justify the term "Race Engine".

    Just remember......


    1. it's easy to build horsepower on a vehicle that has no limit on horsepower

    2. it's hard to build horsepower on a vehicle that has a limit.


    It looks like with Shawns post about the trans we can only build close to 200whp without getting deep into our pockets. Hopefully that FMIC from ZZP will be a nice gain after the normal bolt-ons and tune.
