Would this turbo work for me?

T4 70mm Turbo
Garrett Internals:
Compressor:
70mm / 62 trim wheel
4" Inlet / 2.5" Outlet

Turbine:
.81 A/R
T4 inlet flange

I have a 99 WS6 with Cartek Heads and Cam. I want to do a rear mount turbo, is this too big?

Yep work fine, cam might not though if it's real nasty and tight LSA. What Comp ratio with the heads?

Less LSA would benefit you if you can't decrease the static compression w/gaskets, pistons, chambers, etc. It'd lower your dynamic compression a tad which is all that really matters anyways. The problem is, the less lobe separation you fuel injected guys get, the choppier the idel is. So it'll sound really mean getting more overlap in there to bleed off some pressure. Gotta make up which is more important. You'd be best off getting some good dished pistons and having the chambers ported out a little to get more volume in there though.
