What turbo required for my setup ?

Hi,

Building my setup right now, I'm planning to have a low 10 streetable car.

I'll go for a 109 block, and I'm in negociation with Brian for this tranny : http://www.turbobuick.com/forums/parts-sale/266048-2004r-full-billet-roller-brake.html

What turbo do I need for this setup... since I plan to use it both on the track and the street, I need a quick spool turbo so I think BB could be a good idea.

Right now I'm thinking about a PT6776 bb... maybe a PT70 but is it some kind of overkill ?

Go with the 70 you will have room to grow then.

I'm a bit concern about the spool time of the PT70 ?
What is it compare to the PT6776 ?

to run the times you want you will also need at least stock ported heads cam and the right converter 3600 to 3800rpm range. with a set up like that you should have no problem getting low 10s. oh and a fast system or bigstuff 3 dfi you should have no problem spolling the 70
