Well, if you have a 90mm throttle body then you could put that (note that generally, the good ones cost more than the FAst manifold), and the 90 mm FAST intake manifold, on a stock or near stock engine. I'd expect you'd give up about 25 ft lbs of torque below 4000 RPM and not gain much at the top end versus the smaller FAST manifold, but you'd be set up for future mods including a cam or a stroker. The car would present a bit of a tuning challenge to whoever you had do the re-tune (which with the 90mm you would definately need): you'd want to get someone really good to do the tune or you might have driveability issues around town.
