7afe turbo questions, what turbo? manifold? Options

[CELL_PROTOTYPE_X]

I've had my 94 celica a couple years now and I think it's time to put in a turbo. I don't want to buy a kit, instead I want to get each individual part and the put it all together myself. Right now I need some advice on what tubo to buy, and what manifold to use. I read some articles about the b series manifold which i like because of the flange for an external wastegate, but it seems like there isn't much room below the manifold for the turbo to go. The turbos i'm looking at are the Garrett t3/t04E .48a/r 46 trim, Garrett t25bb, Garrett t3 50 trim .48a/r. I want good low end response and want to run average of about 8 pounds boost. PLEASE HELP ME.

so what are you planning on doing just slapping a turbo on and boosting for awhile till you get money to either swap or build the 7afte? what kind of power are you looking for? at 9.5 psi on garrett i push 170whp and 180 torque pretty much 200 horse to the crank then i pushed it 10-12 psi as my daily driver so probably 195 whp+
