I have 05 M6 with K&N CAI, Kooks Short tube headers, Hi-flo cats, Cat back spin tech, diablosport predator tuner. I haven't gotten the car tuned yet.

My question is that i've called around and i get mixed ideas. One guy from Dominant Motors was giving me suggestions of putting on L92 cylinder heads, eight L92 offset 1.7 intake rocker arms and two L92 rocker arm pedestals, Also new intake manfold. So basicaly new cams, new intake manifold, new heads, new injectors.

I was thinking of a different route. Maybe a twin turbo(procharger). If i get a twin turbo i need a new clutch right? But I'm also worried that having this mod it could ruin the transmission. And any other precaution by having this?

I'm trying to get most power but not go crazy. Its also my daily car. Give me any ideas. Thanks guys

With the twin turbo you will be going crazy...

If you don't go with Dominant MS' advice, I'd go for a heads cam package from some other MS group. I'd add tires and a new shifter to the picture if you have not already switched them, because although they don't give you horsepower directly, the car will feel so much faster with either of those, and your proof will be in time slips.

Turbos and superchargers will make the car a PITA to drive as a DD.

You can do a nice heads/cam/intake package that is streetable and give you very noticible power.

Personally, I would go NO2. Power when you need. Cheap. Safe if you get tuned for it. Or just do 100 dry and your ECU can compensate.

Keep in mind, either route you go, clutch is needed for the extra power.

Forget all that stuff. Change out the torque converter and you will be working the engine in a whole new RPM zone...It makes the car M E A N...

Sorry I see you have manual shift. Therefore I would explore gear ratio changes to your transmission...

No it won't. A procharger or a maggie will give you PLENTY of power and still keep it DD friendly. Maggie's are hands down known for that purpose. Also, plenty of people have the APS kit as a daily driver with no problems whatsoever.

I would even say that if you want serious power that FI is the most affordable option. You could always get nitrous but the problem is you have to spray, it's not available all the time, AND you have to refill the bottle when you run out. An N/A set up will cost you more money to build it right.

The biggest thing people overlook is purchasing your supporting mods (fuel pump, injectors, etc) AND getting a TUNE. Those go a long way in having a proper set up.

Hey man its a great thought to go the twin charger route but....... u need a **** load more than a clutch to support that. were talking New Pistons, new rods, better heads to flow more, better intake, a full dyno tune, possible driveshaft, new rear end parts if u break the 550 mark..... Now if u have 6500 to drop on the charger kit thats great but ur gunna get stompted hard core on the supporting mods. Its ur daily driver and ur gunna need pretty much everything i listed above to run safe.


If your going to do it then do it right dont half ass anyone will tell u that on here. A nice 150 or 125 shot would suit u fine.... I have one and its fine does the job trust me. A nice cam and head package even.

My friend has a Procharged 04 GTO M6. Too much power to be DD. Try driving one when it is wet.. won't happen.

No2 not being avail the whole time is the point... and it costs like $50 bucks to fill a tank and lasts for a good bit. If you burn more then 2 bottles a year as a DD I would be shocked.

I'm not hating on the NA build, but too costly and to put real power down you would need a nasty, PITA cam for a DD.

Problem is DD drivabilty and traction. You just dont' really get that with turbos/superchargers. NO2 is cheaper, better for DD, and easy install.

All have supporting mods of course, but bang for the buck can't beat NO2 for a DD.

thanks guys. so i guess i might just do cam (but i dont know which one) and intake manifold, injectors,heads.

How much HP I'm i going to get from all these tho?


i still might just get a turbo Cause i want to get to 500hp. And ill do what ever it takes. i just want it done the right and safe way for the car with no damage done
