70 or 75 mm would be ideal unless you r prepared to loose a bit of torque on the low end for the benefit of hi end. I was almost into getting it for my setup with my big turbo. Try it and let us know the result.

I was thinkin about 80mm. What ya think......to much?

Toyota MR2 225 using a 55 mm and later upgraded to 60 mm on the 245 with an upgraded turbo. 80 mm on a stock turbo and standard setup wud be a little over as you will experience a lost of bottom end torque. If you do drag and street it will hurt bad and probably eating dust behind the Hondas.....for race would be OK. Big does not necessary good for you, it needs to be balanced.
There are cars dyno @ 725 hp on 60mm TB. and also 650 hp on 62 mm TB.
My preference is still the 60 mm TB as I do not do race. 70mm would be the max.I wud go to.
Wud you like to share your setup? I am currently upgrading my 2 in stages, you can pm me on my private messages.

Bigger piping and fittings + throttle body = more air space and also less air velocity = more work for turbo to fill air space = more lag. Unless fitted with a bigger turbo (which = more lag also).
So it matters whether you are building it for road, track or drag.
