im planning on building a track car with a built b18b on a monster dose of funny fog. I was wondering, for ease of installation, which would be my better choice of a shell, a crx or a hatchback (eg6)? I hear crx's have a bit more difficult wiring. let me know what you guys think.

 

The EG 92-95 hatch makes any hydro B motor swap easier since it bolts in with a mix of stock mounts. With the use of the right OBD components, you can basically make the swap a complete bolt-in and plug n' play with no addtional wiring in most EG's (CX and VX need to convert to 4 wire O2).
With the EF 88-91 Civic or CRX you will need a mount kit. If the car is DPFI then you will need to wire it to MPFI and by using the OBD0 parts it will require no rewiring. I have a 92 VX with a 99 B18C1 and a 91 CRX DX with a 96 B18B1. I like both cars, the VX moreso but they are both solid cars.
The VX feels more natural with the swap, kinda like it came that way stock compared to the CRX. The mount kits use stiffer bushings that cause more vibrations and that's something you learn to live with.
