A friend mine suggested to buy complete new parts on my new full suspension instead of transferring my 8spd system over is it is old. I am considering if I should do that or just or buy new parts. He said I might run into problems later if I use the 8spd.

If new parts, I am going for complete 2008 Shimano XT M770 Series. It will cost $500 tax included for crankset, bottom bracket, rear dérailleur, cassette, and shifter pods.

Of course budget is an issue here. But $500 isn't too much and I am debating if I should go with new parts or use old parts. I also have an old RaceFace Turbine LP which I can put on my new bike. But my new XT purchase must be in bulk (including the crankset) at that price or is a no deal at all.

What do you guys think...all new or go with old parts?

I built up a new suspension frame two years ago because I had been riding the same hardtail for so long. I went for all new 9 speed XT stuff for the FS build and have not regretted it. Kind of during the same time period I had been gathering up some new, some used 8 speed stuff to redo the hardtail (I love my steel Parkpre) because I had hung on to a 7 speed system for so long and THAT was ridiculous to keep replacing stuff. I had all 8 sp stuff except I had bought a new 9sp XT crank with which I was going to use a nine speed chain with the whole works. I just got to thinking about having to try to replace the 8 sp stuff in the future- and I just said screw it. Turned the HT into a nine speed and things are right with the world again.

Unless you just gotta have 8 speed, do what your friend said and build new 9 speed, I agree with him.
No issues, no unavailable parts, now you have new parts, now you have what most serious MTB people have.
