Is it worth the work/money to swap my m6 motor for 8 or 10 or should I just start with a different sled? Or any ideas about a good motor mod....
M6 to M8?

Big bore!
there are lots of 8 or 900 avalable and they will beat a stock 8 all day long!But of coarse there is fuel controller and clutching to deal with.i have a REALLY NICE Union Bay 900 that would really wake that sled up!
It really depends if you want to wrench or not.

What year M6? Overall money wise you'd be better off just buying a new sled.
But, if you really want to keep the one you have.....
There are lots of big bore kits to go from a 6 to an 8. You can take 700 cylinders, bore them to 800, reflash your ECU, get a pipe to match and fuel controller you're in business. If you do this make sure you find a kit that uses stock Cat OEM 800 pistons.

Its an 07...thanks for the help....sledbasher looking at selling that Union Bay kit?
I did it. I swapped out an 06 m6 with a Dakota performance kit. It can with a different pipe, the fuel controller. entire top end, clutching, and can.
It worked well. I did have to spend some time tuning it but it would run with the best. It was ported by Dakota and the pipe was altered by them as well. Lenghthend out in the mid section and shortened at the neck. I Liked the kit and the up grade over all.

I took an 05 M6 and put an 800 top end kit on it. Worked well when it ran, had a kit with the Polaris 800 pistons and the Cat 800 pistons, Cat pistons worked much better, more power and better reliability. I had lots of problems with boondockers though, bad luck I think.

How much did the Dakota Performance kit cost you?
You don't need new pipe if you don't want. HP will be little less with stock pipe than with the after market pipe but there's still 30+ hp over 600cc with just 800 kit and fuel box. You can add pipe, timing etc afterwards when you get used to 800 bb power.
Get one of those kits using 800 Cat pistons. Bullet proof and works like any stock sled (exept more power) after you get clutching and fuel dialed.
RKT and Racing Station 800 kits are proved good ones and there's some other too.

I went with RKTek 8 bigbore on my M7. Stock pipe and skinz super q can, no boony box to deal with. I have a speedwerx pipe sitting on the shelf for next year but will need a boondocker box IF I go that route. Not sure if I'm going to do that yet. Bigbore power and no boondocker box tuning is just too EASY. Clutch it and enjoy it. When you're ready for more power, throw a speedwerx pipe and boondocker box at it. Or twins.
I picked it up used. paid around 1400$
I really have no idea how much it would be new.
I would give them a call.
Dakota performance; I think the guys name it Jeff( I could be wrong).

If you do an 800 kit, talk to a good dealer and they should be able to send your ECU to Cat and the Race Dept can reprogram it. Our old dealer here built one two years ago, it looked exactly like the 600 with an SLP pipe on it. No fuel controller and it out ran most other 800's.
Thanks for all the help guys is it cheaper/more effective to just reflash the stock ECU?

It would probably depend on what your dealer charged you to do it, easier for sure.
Last I heard Cat wasn't reprogramming ECU's anymore, but maybe find a dealer who knows a guy in the race program? IMO, a fuel controller is a must for big bore kits. They give you much more flexibility for tuning for different pipes/heads/porting/etc.
I`ve done it. Look in this tread: http://www.snowest.com/forum/showthread.php?t=113201
800 engine will run on M6 ecu and harness.

Sounds like some tuning required no matter which way I go...not a problem though I think ill go with a big bore kit
I looked into doing this to my 06 M6 and the Speedwerx top end kit is around $1800 give or take a buck all in.
I decided to get their stock head mod with the billet dome for $260.00. That is a cheap 10-15 hp. I figure I will ride it another year or two like this, buy an M8 and keep the M6 for backup.
