its true that you have to buy motor mounts for an 88-91 civic for a b series swap, But....
88-91 OBD0 B16A swap... $1500
92-95 OBD1 B16A swap... $2250
can you say "ouch"?
I'll take $250 for motor mounts over $1250 for an OBD1 B16 anyday.
Although if i had the money, i would get a 5g hatch. I started off as one of the very first modded 4g civics in my town and now (2 1/2 years later) there are about 10 CRX's and 4-5 4g hatches and that is just my circle of friends
I could swap my entire turbo setup over to 92-95 and get a P28 ECU, chip it, run Crome or Uberdata and call it a day.
honestly, my 4g is fast (SOHC VTEC turbo @10psi with a comp cam), but it is a beater. About time to upgrade.
