AUDM DC5R K20A engines produce more power than the AUDM DC2R B18CR after bolt ons.

AUDM DC5R is more restricted from factory than the AUDM DC2R

Only issue with the DC5R is the high dash and the suspension as it tends to be a bit tricky to get to most peopls liking.

I've owned both and overall the DC2R is the better handling car where as the DC5R has the better engine.

And TBH this thread has the most stupid replies I've seen.
