It was my understanding that beginning in 1988, the transmission mounts were changed so a VX transmission will likely not attach to your 86 civic frame.
I also believe that the VX transmission has a hydraulic clutch so you would need to find a slave cylinder/clutch pedal assembly.
I could be wrong on all of this- hopefully someone else can confirm/deny what I am saying.
you are correct, in 1988 the civic engine and tranny changed a great deal, part of it is that more engine and tranny mounts were added, and the engines started useing the D15* number sets insted of the EW* number sets. I think it was still a cable clutch untill 1992 when they switched to hydrolic.
that is why if you want stuff to simply bolt in, sticking with simaler year/body styles is a good idea those being 1969-1972 <--pre-civic air cooled, 1973-1977, 1978-1983, 1984-1987, 1988-1991, 1992-1995, and from 1996 onword I get a bit fuzzy as I've never owned a honda that new, there were a few minor changes in those years, like I think that at some point in the late 80's they changed the splined shaft on the engine, but off hand I don't know what modles/years.
I don't know much about this car, I found an ad on craigslist and liked it so much that I saved the imagies, but couldn't get to it in time to buy it, I think their asking price was like $1,200 and that it was the S modle (pre-SI, carburated)It's so shinny...
sorry, but for some reason I can't get it to insert the image in here, so you just have to Fallow The Link.
I believe you should consider the engine's torque curve when choosing a transmission. StorminMatt's experience attests to this.
The VX's engine was designed to operate well at very low rpm to match the tall gearing, yours perhaps wasn't.
Here's another guy here who had a bad experience with an HF transmission on a 1988-1991 DX:

I think that the problem here is that the DX motor IS designed around higher revs. Given that the 1988-1991 DX motor is the same in both displacement AND HP to the 1984-1987 SI motor, I would expect an HF transmission to have similarly bad results.
IIRC the older motors have peak torque at 2800ish the newer ones 4500ish
I remember The RoadWarrior..To understand who he was, you have to go back to another time..the world was powered by the black fuel & the desert sprouted great cities..Gone now, swept away..two mighty warrior tribes went to war & touched off a blaze which engulfed them all. Without fuel, they were nothing..thundering machines sputtered & stopped..Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice
