Why 'wud' you question my concise, well thought out posts in this thread if you can't be bothered to spell things properly? I honestly imagine ignorance is to blame, so just for fun I'm going to smoke you. Try to keep up.

what about lag and the fact that its an automatic car with a redline of less than 6K. if you were to push it, then it wud upshift, then where will you be? sitting in the nonboost zone for a second waiting for turbo Vtec to kick in?

What do you get if you don't have a turbo? Lag until redline and then more lag, because you never get any boost. Why is a turbo a good idea? Because off-idle torque is the enemy of a heavy front-wheel drive car... That is what a positive displacement blower is all about. If we're talking centrif, then the same RPM arguments could be made for both centrif blowers and turbos...oh wait, but I've seen Mustang Automatics with both...and they both worked, nicely...and they don't have 8k rpm redlines.
A turbo isn't anything like VTEC anyway, so I hope you're just trying to be cute.
Unless you have a moron of a monkey putting together your turbo system, it is easy to have a low boost threshold (this means 'lag' time) and a reasonable power increase in absolutely any car. Don't you think those turbodiesel pickup trucks with automatics stay in boost through the upshifts? Well they do, and I promise that they're NOT revving up to 6k rpm. Now you'll tell me that those don't work either. (We won't even mention the Buick Grand National, v6 automatic that B+O brought up, because I'm sure you read this whole thread).
In FACT an automatic is an excellent platform for a turbo, instead of more lag there is no lag on the upshifts because the engine stays under load 100% of the time. There is no "nonboost zone" once you have overcome the boost threshold in an automatic car. THERE IS NONE. The turbo would have to be seriously mismatched for there to even be a drop in boost pressure for a street car. The obvious exception would be a GT42R powered EVO that runs with no wastegate, so boost is directly dependent on RPMs, but we're not talking 800hp and we're not talking about running with no wastegate, so that is out.
Quite simply, and I'll make this VERY simple for you. Take this turbo:
T3/T04B 60-1, .63 A/R turbine housing, Stage 3 turbine wheel.
Put it on an RL with a properly sized intercooler, 3" exhaust, and get the engine management right, and it would rock the house. At 10psi you could support 300-400hp depending on supporting mods, and at 15psi 400-450bhp. I would expect full boost at 2300rpm which is right where the torque converter stall is...it couldn't be more perfect than that.
If you have even the smallest bit of intelligent insight, I'd like to hear it, but since I'm sure you 'wud' have said something intelligent already I'll continue.

supercharger wud be best for this car but its only purpose wud be to get in the passing lane and attempt to keep up with the E63 and M5 that just blew by you.

They can blow me all they want, and so can you. Cheers!
