ct26 highflow?

G'day, just wondering if you guys do turbo highflows/rebuilds? I heard there is an option available with the MR2 ct26 to bolt up a larger rear housing from a supra ct26. How accurate is this? Just wondering if you could build a ct26 with a larger trim comp wheel (to4?) and couple it with the larger rear housing to achieve a fairly decent bolt on highflow?

Cheers
