| Yes, I am talking about the M60 to M62 swap, and it depends on your definition of not yielding much at all. First of all I'm doing a 6spd manual (M5 tranny) conversion with a custom geared LSD (3.45). The M62 has the same HP as the M60 but more torque. The 840 is already lighter in front than the 850 by about 100lbs., so combine that with another 300+ lbs. lightened by losing the automatic and torque converter, 75-100lbs. from a lighter custom exhaust system, plus another couple hundred from other tricks I have planned, and it begins to make a real difference. Using the UUC LTW flywheel and the big 280mm CSI clutch with the rear gears will get the 8er going very well and keep into the better power band of the M62. My initial approach to performance with my 8 is not to throw tons of money at trying to produce more horsepower, but rather to give a good engine all the breaks to let out and use the pretty decent HP and torque it already has. Sure, if money were no object I'd put the S62 in, but I can do all the mods above and bolt on a supercharger for less than the cost of the engine alone. When all is said and done I want a clean, smooth, performer at a reasonable cost.  |
