420A 420a CV Axles and Transmission question?

[BuiltFourTwenty]

How much HP can the basic 420a CV Axles and stock transmission handle? I just recently purchased a 5spd and In the process of building it to handle a turbo setup. I have a good idea of the engine mods Ill need but the transmission and axles are keeping me second guessing.

Can anyone give me an estimate of numbers or does anyone have any experience with this? Thanks.

You might want to ask in the 2g na/t forum.

I know I am not suppose to say this but I have heard that they (axles) are good up to 400 Hp. BC that is one my concerns too, I mean at least we can upgrade our axles for about a $1000-00 but to my knowledge there is nothing for our gearboxes at least they are a dime a dozen, right!!!
