To the OP, why the hell would you even consider using the S4 block and bottom end if you had the RS4 pieces?
oh well.. life goes on.

If you can get RS4 engine with reasonable price, get it. I would use it because it has stronger crankshaft and con rods, bigger oil pump, better block and heads, cams and so on. Many things. Then you just have to change the turbos to bigger, thats basically it.

with the 3rd and 4th grears being different does that not mean the gears are different?? lol. I know why people go with it. I remember back in the day when jared (snowtrooper) was trying to get one for drag purposes. With going with all the power that he wants to do, why would you not go with the RS4 rear if your doing the motor and trans?? Makes sense, sense these rears like to break.
Your not going to get an rs4 motor for a good price, and a good price will be expensive. euro>dollar, shipping will be crazy expensive.. By that time your better off just doing what isaam said, and a built stasis trans. It will be stronger, more reliable, and hold more power.

But all the other RS4 "goodies" is the "thing" that makes it tempting, if the price is reasonable.
600hp at the motor.. Shit why even bother going Gt's?? Why not go rs6?? cheaper. You can make 600 to the motor on race gas with ko4's.
RS4 goodies are also a waste of money. Show me any dyno that prooves a result of more then 15whp for all of that money spent on rs4 intake mani, fuel rail, TB, head, etc.

I was told that S4 has better trans than RS4 and stronger and S4 and RS4 have different engine blocks and trans won't fit (RS4 block+s4 trans wont' work)[/QUOTE]
Do rods, and s4 bearings and youll be fine.
s4 and rs4 have the same block (correct me if im wrong) and the bell housing fits right on.
I think your better off making a thread saying what you already have, What kind of power band, hp, tq, etc. you want. What you want to use the car from, and ask for advice from there..
If you got the motor, and trans and shipped here for less then $2500 then you are the man! I prefer the RS4 trans because its better for drag, but everyone is different.
