Default Turbo--good for FM?

MP t-70
P-trim/.68 A/R size

Would this be a good turbo for a front mount setup? How much power is capable with this turbo up front.I will have plenty of fuel with the new setup and the proper tune. engine CR is 8.1:1
Also, what size piping is being used to make around 900rwhp?
Thanks

They use the MP on this kit from forced inductions. I have no personal experience with it though. On the same web page you can calculate your turbo needs under "turbo 101"

-The exhaust housing at .68 A/R is way too small. Thats more for cars with twin turbo's or a single on a 4cyl. to get it spool faster. You want a .96 A/R.
-I don't think a t-70 is going to get you there. You want a T76-GTS. Good for roughly 1050-1100 crank hp / 900-950 rwhp.
-Piping.... don't really know. I'm guessing 2.5" or 2.75" piping to turbo from manifold's. 3.5" to 4" downpipe. 4" IC piping.

Sorry, when I was talking about the 900rwhp, i was thinking ahead so when the piping was made, it wouldnt limit another turbo when I switch them. I was wondering more what that turbo up top could make?
Thanks

Try using our Turbo Calculator. You can enter information on your motor and plot the output directly on several turbo maps. See attached sample output. As you can see on the attachment that turbo will be too small for your application.
