Not sure but if you read Performance Ford magazine, over the past year there has been a few features of guys who have got their FRS's up to 360+ bhp without touching bottom end. I read somewhere that the bottom end standard is pritty strong, but I have also read that a few guys have put in WRC bottom end running gear.

I'm fancying a GT 28 upgrade but my main concern is how the hell do I get the power to the road I mean I already have to ease off and feather the power to the front wheels to avoid wheelspin and thats with GGR air filter,GGR sport cat, Bluefin, dump valve and Milltek cat back exhaust. Think I may need more grippy rubber, I'm Michelin Pilot Sport 2's at the moment so I will maybe try Yokahama Parada's as they seem to be popular on alot of feature cars.

Keep sharing the info guys
