I know the compression ratio is higher on the natural aspirated engine, but would the turbo intake exhaust manifold bolt right up or are the engines different? Is the bottom end basically the same?

 

If you want a turbo, why not just sell the base model and get an S? Adding a turbo to an NA would be complicated and expensive, and these are not rare cars or anything.

 

Taxes, registration fees, already have this one...

Same transmission?

 

I looked at the same when my Justa fell in my lap. There are many differences. Everything I read basically pointed to 3 reasons it won't work: non-S crank, rod and pistons can't handle the power, same with the transmission, and computer stuff. not to mention exhaust(which could lead to body work). now, I'm more interested in whether an S transmission will fit a non-S
