I will not change my mind on this, if I had the choice of an M10 or an M30 sitting in front of me, with all the turbo parts at my disposal, it would still be a no brainer!
A bunch of people on the board have read Maximum Boost by Corky Bell... Those who have should be able to see why I'm questioning this. Mr. Deagle is running a 304 cam and wants to push 2 bar of boost. I'm not arguing that it wont make the power, but driving it is gonna be a bitch compared to a 315rwhp M30!! From a drivavility standpoint alone, I bet if you had two identically prepared chassis with adequate sized tires and you put a turbo M10 in one, a turbo M30 in the other, both making close to the same amount of power, the M30 would walk away from it on a twisty road because of the flexibility of the torque curve.
It's easy to see how hard it would be to drive a car fast, smooth, and safe with a torque band that is 2000rpm wide, whereas a turbo M30 that makes over 300rwft/lbs from 2000 to 6000rpm would be much easier. Not to mention that the turbo on the M30 isn't going to have to work as hard, it's got more gas flowing through it to spool up quick, and it's pushing less than half the boost to make the same power... If you could easily fit 265s on the rear of an E30, it would be safer and easier to drive with a peaky, small displacement, high boost motor. But since you can't, that's something to take into consideration! Traction issues on boost don't generally help you when you are trying to blast around a corner. Unless you are a drifter...
My mind is made up!
I'm glad for Mr. Deagle, he's gonna have a sweet E30 with that boosted M10, I'm just questioning the logic because I don't know if he plans on auto-x, trackdays, drag racing, or just fucking around on the street.
