According to this thread Honda-Tech.com: Hybrid: Finally, the TRUTH regarding K-Series vs. B-Series engine weights! the b-series motor and tranny is around 100lbs more than a d-series motor and tranny... and according to this https://hondaswap.com/reference-materials/honda-acura-vehicle-chassis-weights-28662/ an 88 HF weighes 1819lbs... so that would put an 88 HF at around 1920lbs...A b series motor doesn't weight 250lbs more than a d. There's only about a 50lb difference which would make it weigh in at 2000lbs.
Last thing I have to say is I think it is possible to take 200lbs off a crx hf to make it weight under 1800lbs with a B series swap without cutting the crap out of it.
It also helps that my car weighs less the 1,800 pounds. See if you can lose weight somewhere, unless it looks really nice then leave it be and add some power. That B18c should have no problem getting the power you want, just depends how deep the pockets are and if you and some buddies have time and knowledge to piece it all together.

I'd also agree that you could easily shave some weight to get to 1800lbs however, that still doesn't change the fact that an HF that sips gas, is mated to a tranny geared to help do it, gets less MPG's than this MazdaASpec's modded b-series engine in his CRX that has mated to a tranny geared for acceration (I highly doubt he's running an LS tranny).
Let's just say your average B-Series, lets say it's an integra gsr, lightly modded gets 25 mpg's. I don't care what anyone says, by just throwing that same motor in a 1800lbs car isn't gonna double the MPG's...
EDIT: Just saw that he has a 91 HF, they weigh in at 1967lbs, that would put his car around 2070lbs with the B20/Vtec. At that weight, 1800lbs seems just that much farther... Plus what ever he weighs... do able, yes, but highly unlikely...
Here's a car that was built in good taste ( eg. non ricer. Ok maybe the wheels...) ;-)
LS/Vtec
12:1 compression JE pistons
Eagle rods
Cometic 0.051" head gasket to lower compression to that
stock 81mm bore
Skunk2 Pro Intake manifold and 68mm throttle body
Hondata IM gasket
GSR head
Skunk2 Pro valve springs
Skunk2 retainers
Skunk2 Stage 3 cams
AEM tru time cam gears
Type R oil/water pumps
GSR tranny
11lb flywheel
Stage 2 exedy clutch
I have a polished ss hytech header waiting to go on
P28 Chipped by me running crome on an ostrich eprom emulator
LC-1 wide band with o meter
Picture was taken before the cams and headwork so you won't see cam gears.
The whole body of the car is stock but the front emblem was shaved and the side rub strips are painted. Fresh paint last winter. Oh and the painted ricer mirrors I didn't put them or the wheels on.
Let me drive it, i'll do that for you lolNot 100% sure yet. Still have to get it tuned.
The butt dyno likes it though and it hauls pretty good all the way to 9k. I won't take it any higher than that.
Lol me either ;-)Let me drive it, i'll do that for you lol
