Jared

it depends, the 90-91 is electronically different from the 92-93

90 ls

B18C5-EH2

From the JDM CRX/Civic SiR or Integra Xs-i:

Engine
Tranny (not a must-have, but see below)
ECU (PW0 or PR3)

From any USDM 1990-1993 Integra:
Rear mounting bracket
Axles

Wire up the VTEC

You've already got the axles and the halfshaft covered, and the rear bracket too

I would get the B16A with a JDM J1/S1 since your LS tranny will kill the acceleration on a stock or all-motor B16A

Good luck!
