If someone asks for advice, they'll get it. He wants 400 whp, and the best way to get it is with a turbo. The M90 is so inefficient its ridiculous. He'd be maxing EVERYTHING out to get 400 with it. With a turbo he'd be able to hit 400 and have room to spare. I'd rather go that route than be running on the edge of everything just to hit that number.

There are so many people on this very board who have stayed with an M90 just to say they did it and they regret it saying they should have went turbo in the first place. He'll be beating his head off a wall if he tries to stay with the M90. I'd rather someone tell me to try something different than for me to waste time, money, resources etc on an unrealistic goal.
