    Boosting a N/A motor

    Hey guys my buddy just got a 06 GTI SE and I am wondering if you can change out the pto housing and put a charger on it, Yes i know the fueling and other stuff would have to be played with just wondering if a stock 185 or 215 charger would go on and what you would have to change to get it on the motor.

    I think the pistons are different. Different compression ratio.

    yeah its 8.4:1 in a SC ski and 10.2 or something like that in a N/A motor i know but if u run no I/C and enough fuel it should be ok with a thicker head gasket.

    just a few things i could think of you'd need would be:

    SCIC Intake Manifold, cause im pretty sure the GTI TB is on the wrong side
    Stock IC
    SCIC PTO Housing
    SCIC Flywheel
    SCIC ECU & Wiring Harness
    Map Sensor
    SCIC Pistons

    told you he shoulda bought my buddies RXP for 5k....

    Could always put a turbo on it to see how long it will last if boosted too high..!!

    Compression is far too high on N/A.
    Pistons are forged in SCIC motor.
    Bearings are stronger/better metal.
    Oil pressure is higher, and better.
    Crank is stronger.
    Rods are stronger.
    Cam is correct for forde-fed engine and head.
    Valves better technology.
    Electronics are more complex.
    etc, etc.

    Then there's the hull... a few things there too.

    The internals are all the same cams,rods,bearings,valves,oil presure and crank are all the same for sure.The pistons should be changed even though the 185 GTX uses cast pistons.The compression is to high.

    Sorry, I gotta dis-agree with ya there.

    Anyways... If you want to try it, and blow it apart, then go for it. But by the time you re-build one... and figure out it wasn't worth it.

    Turbo may be a good idea, but go for a better cam, it will reap benefits.

    Mild tune tho'...... or POP.

    If I had the spare I'd like to try a project like this.

    I did build a turbo GTI with the stock motor.I only change the pistons and ran 18 psi boost with no problems.

    I just went on the oem parts and all the part #'s are the same.The crank,valves,cam,bearings and rods.The only differance is the pistons and pto cover I beet on that.
