228R or MS3
The car is not a DD nor will it see track use. However, I would like it to pull hard all throughout the powerband without losing too much on the bottom. Realistically this car will run more often at 1000-4000rpm more so than redline.
I was thinking 228r but don't want to regret it and wish I would have went bigger. Is the MS3 too big for a weekend warrior or is the 228r better suited to what I'll be doing (just some occasional street races at stop lights) Thanks for any suggestions/recommendations.
Based on your post something around the 228r is much more in line with your goals.
Auto or manual? If auto you better have a stall, if not get that instead.
I would atleast go with something like the TSP Torquer 2 232/234 or the 233/239.

The car is an M6 for those asking. Full bolt ons.
Basically what Im saying is, it comes down to the tune. Any size cam can be very streetable, as long as the person tuning it knows what he is doing.
as far as the ms3, I made 351rwhp, 355rwtq with just long tubes through the stock catback before it. After the cam install, tune and a catback I made 412rwhp, 381 rwtq. The feeling of the power band on the ms3 is pretty intense. It is sluggish below 3400rpms, but at 4k, its like spraying a instant 100 shot. It just turns on pretty harsh. I love it. My revv limiter is at 7100rpms, but I shift around 6600 on/off the bottle....however, even with my stock ls6 intake manifold and stock 241 heads, the power never fell off to 7k. It stayed linear at 410rwhp from 6500-7k.
here at my place, I had my dyno sheets side by side from the long tubes compared to the ms3 etc and I still gained power and torque as soon as the peddle hit the floor with the ms3 over the long tubes/ory...
so in other words, I didnt lose any power...I gained power.
I will actually see if I can find up my old thread in the search with my side by side comparison.

If you bother to upgrade gears switching from 3:42's to 3:73's will not justify the cost. At least go with 3:90's.
