Swap that VX trans into the HX and use your 15" lightweight wheels and you will have highway cruise gearing taller than the original VX and approaching the 4th gen HF. You could put a Kamm on the HX much more easily than you can swap that HX engine into the VX. But I understand the passion for the better looking car, so if you feel confident and can spend the time, go for it. Have you studied aerocivic's mods to his CX/VX? You could do a lot. Also 3wheeler's insight boat tail -- both are amazing pieces of work.
Yep. I have a 5th gen VX (1994) trans in my sixth gen CX (1997). I bought it for $150 on CL and it is great. It performs the same as the CX did with the factory 6th gen CX trans but without the bearing noise. Both ran 1700 RPMs at 55 mph. in my opinion, they are the same transmission. I think there is a lot of misinformation on the 6th gen CX gearing on the internet. Probably becasue there are so few CX's and the majority of them get swapped with a faster engine and trans. There are also many debates on what the differences between a DX and CX hatchback. The CX is lighter and gets much better gas mileage. The trans is the main reason why.

I still have the old CX high geared transmission. If there is a way to identify them as high geared, just let me know. I was hoping to rebuild it and swap it into the HX first. It might be more cost effective to pick up another used 92-95 VX trans though. Swapping the transmission takes very little time and would be a good test of the cars efficiency. Then when I have more time, I will swap the entire dropout over to the CX.
I have been a long time lurker on this website. I joined back in 2008! I have followed both of those cars for quite some time. In fact, 3-wheelers car is actually the desktop picture on my computer. lol
