I have a 96 Honda Civic lx sedan and I want to do a B20 Swap, but I don’t know everything I would need any help?

 

Roughly what you'll need to get a basic swap up and running:

• B20 (CRV) Engine (newer the better)
• B18B (LS) Intake manifold (or aftermarket for a B18A/B) with 96+ Integra RS, LS, GS throttle body, sensors, injectors
• 94+ Integra RS, LS, GS, GS-R, Type R or 99-2000 Civic Si transmission, clutch, flywheel, throw out bearing, pilot bearing
• Mount kit for 96-2000 Civic with B-series swap or 99-2000 Civic Si mounts
• Buy a wiring kit or modify your existing engine harness to fit the layout of the LS engine
• 96+ Integra RS, LS, GS OBD2a ECU (P75)
• Shift linkage from 94+ Integra RS, LS, GS, GS-R, Type R, 99-2000 Civic Si or 94+ Del Sol VTEC
• Axels from 94+ Integra RS, LS, GS, GS-R, Type R, 99-2000 Civic Si or 94+ Del Sol VTEC

If you actually make it that far, check deeper in the forums. There are many, many threads on this and the non-vtec B20/B18 swap is about as easy as it gets.
