    Difference in 130 vs 155 4tec

    Looking at buying a 07 GTI that was hydro-locked. What the difference in the 130 vs 155 engines, bore and stroke? I'm assuming both are NA.

    The difference is that one has 25 HP more than the other, LOL.

    Seriously, the only difference between the two is a different cam and different ECU. All other engine parts are the same.

    I hope you know what can happen to hydro locked skis after they've been cleaned out and up and running again..

    I've seen a few blow a rod thru the block within the 1st 10 hrs of riding..

    I'm not saying it always happens but it has happened.

    I agree. As a precaution, I believe it is good practice to throw away connecting rods that have been in a hydrolocked engine. I also wont reuse a rod in a cylinder that has dropped a valve for the same reason.
