[FONT=Calibri][SIZE=3]Howdy, I need to wrangle new engine into my 03 S. I have a great lead on a 06 1.6 but not supercharged. Other than the supercharger and flywheel, are the two engines the same? In theory, can I bolt my supercharger and my trainy on the 06 engine and drop it in.[/SIZE][/FONT]

 

The base model Cooper's engine doesn't have forged internals. Not sure how much boost it could handle, but probably not a good idea to bolt the s/c to it.

 

No....

 

The cooper engine has very high compression where as the cooper S engine has lower compression as it was designed to run with a supercharger. Bolting a supercharger to the already high compression cooper engine would not be a good thing

 

Can't do it. They're not the exact same engine...

 

Don't waste your time.....

 

Can't do it!

Just thought I would say this since nobody else has.

 

Thanks for the info. Anyone got a S engine they want to sell?

 

What is wrong with the engine you have?
