i would be interested....how do you plan to lower the compression ratio? custom pistons?
I am in the process of working on either a supercharger or twin turbo in the N62 engines. Fully installed approximately $10K. Just gauging some interests to see who would be interested. Should reach around 500 HP and 400-500 ft-lb torque. It's all up in the air right now. I may take a plunge into this.

I think this will just be a headache for you in the end man. You're probably going to ruin your engine. Lots of maintenance and tinkering and tuning.
I think you best bet is M5 with bolt on mods. Keep it NA. More reliable in the long run.
But that's just my opinion. This looks like a thread of NA vs Turbo / Supercharge.

I dont think we would need to lower the compression. I would imagine that the 10k price quote does not include a set of pistons. Swapping a good set of pistons in and lowering compression would yield some serious boost. With low boost, 6-8psi, the stock compression ratio should be ok. Obviously a good tune is extremely important...

True that! Man our cars would haul major ass with a supercharger or turbo kit. So you think around 500hp to the wheels? That is some scary power. I wonder how reliable these engines are boosted. If they're anywhere near as bulletproof as the 2JZ-GTE engine that would rock.
yeah dude those 2jz engines are very interesting

There could potentially be a small market for this. Take myslef for instance, recently purchased an 04 545i 6mt. I definately paid way less than 10g's for your standard used e60 m5 out there. For the 10g's I would still be saving a nice chunk over an M5 and would be faster than a stock M5, albeit not my much. First concern though is the clutch, does anyone make a performance clutch for the N62? Will an M5 clutch set up fit? Then you will always have to deal with the stigma "yea but its still not an M car". Just some thoughts....
Ive searched (i had to replace my clutch last year) and i remember coming across one that deletes the SAC. But when it came time to order the part i couldnt find it and none of the guys i use locally could find anything either.

In the words of Paul Walker from Fast and the Furious Uno... "Don't race him (Johnny Tran), he probably has over $100 grand under that hood." In this case, it's more like half a billion... hah nice picture PTL.

3-4psi max, or you'll fersure hole a piston
