at least without extensive modification of the plenum. ASH managed to do it but had to purchase a very expensive specific welder that allowed him to modify it. Just for the record, I tried this about a year ago and bought a bunch of TB's to try and find one that would fit directly to the Z32 intake...no dice. I still got over a $100 worth or used TB's from various junk yards in my garage to prove it. BTW- disassembly, modification and re-assembly are still going to be needed to make them work regardless even if you ever find a set that matches. You will need to dismantle at least 1 TB and re-set the TB butterfly and butterfly pin to the inner direction as well as considering butterfly pin length...TPS...fitment to the TB linkage in the center...and you will have to set both TB's to match butterfly positioning.
I would recommend sending yours off to o2induction.com as they do good work at a great price. There is even a picture of a bored out completed set on their site.
As far as numbers I don't think anyone has ever done a good comparo on these.
