CRX Hf shell/VX engine/tranny?

[sebass]

Hi guys. I was thinking about buying crx shell ($800) and buying brand new vx engine and installing it into crx hf body. Engine cost is $350. Not sure how to go about getting a HF tranny. Maybe brand new aftermarket tranny to HF specs? Is there something like that out there? Is VX tranny or are there any other honda tranny's manual that are same gear ration (tall gears) as HF gears? How much do u guy think installation cost (rough estimate) would be for all that? Is this worth a hassle? How many MPG would this frankenstine get? I figure VX gets 49 but it's 200lbs heavier then CRX HF so VX engine can get 52mpg+ if it would be in CRX body? Any replays would be very much appreciated.
