B18b1 into 97 civic hatch
Just picked up a 97 civic hatch w/ no motor and no tranny. I'm not sure what motor was in there before but maybe a d16y8? Anyways..
I'm looking to put in a B18b1 from a 97 integra LS that I have my eye on. What do I need to do a complete swap beside the obvious (eng/trans)?
I do realize this topic has probably been beatin to death. I did a couple of quick searches but found plenty of GSR, k's, and other swaps but nothing as simple as what i'm asking..
Any help is much appreciated!

You will need:
-96-98 P75 ecu, or a 94-95 P75 ecu with a stepdown harness.
-94-01 integra/99-00 Si shift linkage.
-94-01 integra/99-00 Si axles
-99-00 Si rear t-bracket
-Don't forget to rewire the IACV wires at the ecu.
-94-01 integra/99-00 Si lower torque mount bracket
Other than that the whole thing is drop in and plug and play. I would recommend upgrading the driver side upper mount; the stock jelly mounts tend to break.

-Will also need to adapt the IAT
-Use the 99-00 Civic Si mount that bolts to the timing belt side of the block
-extend secondary 02
-modify exhaust to fit the new configuration including catalytic coverter

^^^^^ this good info that most people dont know about of think about until they get to that part of the swap and go "Oh **** my O2 sensor wont fit". Password JDM makes nice O2 sensor extension harnesses.
Re: B18b1 into 97 civic hatch
Your best bet is to go to the dealer to get the t bracket and mount. They bout $60 each and new. It's a pain in the butt trying to find em used. The exhaust issue all depends on the manifolds year. As the older b18s have shorter length down pipes.
