    M50b20 with welded 3.15

    So i want to swap my 3.45 open with a 3.15 welded. How the engine willy take it? Too long considering that my touring has a lpg conversion wich when activated drops the horsepower to about 130.?

    The car i use it only 1 or 2 days a week at most, and i want to have some fun
    ... then regret the stupid decisions i made.
    I don t really want to weld mine and i will keep it as a back up.

    What about all that full opposite lock, sideways, tire roasting precision drifting fun those mighty 2 liters will provide?

    If you can leave two black stripes from the exit of one corner to the braking zone of the next, you have enough horsepower. - Mark Donohue

    Yeah sure, a V8 is nice, but If you need a V8 to do some skids in a parking lot, than you are doing something wrong.
