[QUOTE="fabianyee, post: 615848, member: 6"] the N52B25 is supposedly running 216hp at crank.. to have another 30-40whp would bring it above 100hp/liter staying NA and assuming retaining same engine capacity. Not impossible but lots of work needs to be done.. high lift cams, lighter valvetrain, 1000rpm higher redline. lightened pistons, lightened crankshaft, lightened con rods, higher compression, dual bank injection. that's like building a semi race engine aledi... sell the car and get the 335i. end of story.. Unless you have a workshop and make it a challenge to do it yourself. [/QUOTE]
