I have a an auto tranny with ddp 90 injectors, 150 fass, 5" exhaust, smarty s with ts mp8. wanting to hit 700 hp what intake system and turbo would be best for me?

I have read that there is not much to be gained on the intake side [ even though there are things you can buy for a lot of money & look good , some testing has not shown much improvement ] .
But a bigger turbo would be called for , somewhere a while back I saw a chart showing many turbo's and HP levels for each , I lost my copy and not seen again , but maybe with this post someone will bring back , It would be a good tech. sticky .

Your going to have to run a big turbo like a htt 66/71/13ss or a silver bullet to get close to 700 hp and you'll have to upgrade to a stg 2 or 3 cp3.

Agreed...

Silver bullet minimum for single turbo, twins would be better. Stage 3 cp3 and even then with the DDP90's it will be tough. Possible, but unlikely. You don't have your sig filled out so it makes a difference if you have an 03-04 vs 04.5 and up... because you have a better chance of hitting your number if you have the latter.

More likely to be in mid/upper 600's either way provided you have the necessary supporting mods.
