Can it be done from an '03 MCS's to an '04 MCa? How radical is this op?

 

It is quite simple. Sell the '04 MCa... Use the cash to buy a '03 MCS

I think that while possible it would be far too costly to remanufacture the car. But if you have the $$$ Speed's Tuner Transformation has converted 330's from slushbox to manual.

 

I didn't think it'd be that huge, just the labor for the swap. Situation would have been finding a cheap MCa and having the tranny.
Thx

 

Are you sure that you dont just want to sell the MC and get the MCS? I testdrove both, and I HAD to have the MCS. I got one of the first MCSa's!
