my buddy wants to put a b18 into his 92 cx hatch and he has a d15 in it now. how hard is the swap? any fabrication needed or pretty basic?

 

El search-o next time, por favor.

Here's just a couple of the findings, from a sticky at top of the forum:

Good luck and have fun!

 

the swap isnt hard.. youll need new mounts though, and youll need to wire your car for vtec.. unless the cx is pre-wired.. i dont remeber.but yeah plenty of answers, just search.

 

it pretty easy if you got a cherry picker etc you will need everthing from the b18 motor better off with ob1 motor cause its plug and play

 

b18A? B? C1? C5? Is it OBD0, 1, 2?

If its an OBD1 B18C1 you'll need to either wire up VTEC solenoid, VTEC pressure switch, Knock sensor, IAB's, and add a 4 wire O2 harness. Or get a 94-95 B18C engine harness and plug and play.

 

its a b18b

Assuming it is an OBD-1 engine (since you neglected to answer that question), you can just drop the engine in using the CX harness; the only wiring that will be required is for the O2 sensor (1-wire vs. heated 4-wire). If you have the B18B engine harness, that will just plug-and-play with the CX chassis harness. The OBD-1 P75 ECU will swap right in place of the CX P05.

You'll need the '94-01 Integra axles (assuming you're using the hydraulic-clutch transmission and corresponding intermediate shaft that goes with the B18B), '94-01 Integra shift linkage and shift lever (or modify the Integra linkage to fit the Civic shifter, or use '99-00 Civic Si linkage with the stock shifter), various maintenance bits (timing belt, water pump, accessory belts, fluids including engine oil, transmission oil, coolant, and brake fluid to bleed the clutch system; main seals, oil pan gasket if leaking, cam seals, valve cover gasket, spark plugs, clutch/flywheel, etc.), a del Sol VTEC A/C compressor bracket if the CX has A/C and you want to retain it, and these mounts:

You can use the mount from a Del Sol VTEC as well, but not the 99-00 [Civic Si] mount because it is totally different.

For the rear mount you will need to use a 1994-2001 Integra rear bracket. The actual rubber mount that bolts to the rear subframe can be the stock civic one. [...]

The topside tranny mount can be the Civic [...] one - it is the same thing.

The front mounting brackets need to be from an Integra [1994]-2001, but if you want to keep A/C then get the A/C bracket for a Del Sol VTEC model. the actaul mounts that bolt to the underside of the framerails need to be the stock Civic ones.</TD></TR></TABLE>



You'll also need to figure out exhaust manifold and intake arm fitment.

Obviously I am missing a few minor bits, but you'll see them as you run into them. Integra-to-Civic engine swaps are extremely common and there is a nearly infinite amount of information and help for these already published on the Internet. Please use the search (H-T and Google) and read the FAQ sticky threads. Also make sure to check/search the H-T Hybrid forum.
