Pls don't get the GDI... i know it's newer than the CM5A GSR, but you will regret later...
I was in the same situation as you 2 years ago... 160bhp vs 205bhp... so logically went with the GSR... loving it so far.
but its only on paper...but when dyno the hp will down bout 5-15%...yeah!!! buts it's true better you take the GSR stock hp is more then the GDI TURBO.....
