I do not know your cams but if they make peak Hp like stock or SC's at around 5500 to 6000rpm, any turbo that works well on a CIS 3.3 is going to work better on your EFI 3.2.

A K27-7200 is a great turbo for early boost and big response for up to about 425fwhp on an EFI car but wont pull more than about .9 bar at a 6500rpm red line as it runs out of steam and efficiency. If you are running a bump in compression and plan to keep boost at or below .8 bar it could be fun and easy to fit.

The HF's and GT 35 is going to support more HP. The GT's can be a small challenge getting the oiling right but seem to be a more modern and efficient design. An added plus of the GT's is the ability to easily change hot housings for different style of mounts and A/R's.

The 3.0 crank and rods can run safely to a higher RPM than a 3.3 so it would be fun to build a 3.2 short stroke turbo that makes HP at a higher rpm (up to 7300rpm+ red line). If that is done a larger hot side, big ports, and a cam to support it would be needed but at the expense of low end response. This strategy could make more HP than a built 3.3 if done right.

Not an expert, just my opinion.
