#217511 Have you looked at Chrono's DelSol Built thread here?

Starting on page three he mentions getting a new Tee bracket for the swap. The other pages mention items like extending the O2 sensor wiring, shift linkage and exhaust changes needed. Should get you stated and answer most questions.

#217530 What you will beed to MOUNT the engine into your civic.

DC integra Driver side and Tranny mount.
B series rear T bracket. The mount from your civic will work. Just need the metal T bracket.

DC/EK axles and Half shaft.


if your motor is obd2 you will need the proper harness adapter. whether it be obd2a or obd2b. You will also need OBD1 alternator, Distributor and Injectors. You can still use your current civics engine harness.

You can run the motor on a P75 LS ecu. It will run just fine. If you concerned on the matter, take it to a tuner and get them to chip it with a b20 basemap.

You will also need to pick up a stock or after market LS intake manifold.

You will not be able to use the B20s tranny and will need to find another Hydro B series tranny. IE LS, GSR, ITR or B16a.

It is a relatively easy swap on all parts. I currently have a B20z in my car.
