I am just starting the process (removing B18A1) thats in my 92 Civic. Planning on buying a JDM B18C from hmotorsonline in a few days. Its a complete swap for 4900.00. What else do I need to complete it. I'm not sure on the brakes/hubs. Do the splines have the same count? Will the little Civic brakes stop the extra weight of the motor? Any info will be helpfull on every subject.

 

Welcome to the site.
We have a specific forum for engine swaps, but since you're also inquiring about brake upgrades for your Civic, you'll be best served by the 92+ Civic / Del Sol / EL forum.

I'm moving your thread there now.

As far as the swap goes, the B18C will re-use the mounts you installed with the B18A1. If the mounts need replacing, I'd do it now. Your existing axles and hubs will do fine as well, but if you have plans for major power upgrades (i.e, turbo), this would be the time to upgrade.

I'll leave the brake upgrade question to the Civic forum. IMO, a rear disc conversion would be nice.. but your front brakes will be taking more strain.

Assuming you are running an unmodified ECU, you'll need to add a couple wires to control the VTEC oil solenoid and input from the knock sensor. Check out the Engine Swaps, Tech & Tuning forum for more info.

 

What model is your '92 civic?

A b-series motor doesn't weigh all that much more than a d-series. If you're swapping from a b18a to a b18c, the weight difference will be negligible, but upgrading the brakes is probably a good idea anyway. The brakes that came on CX, VX and DX civics are inadequate for anything more than basic commuting.

Regardless of b-series/d-series, the axles/hubs all have the same spline count, so swapping the brakes wont require new axles. Going on the assumption that you have a CX, VX or DX civic, I recommend a full front and rear brake swap.

What you'll need:

FRONT: front knuckles, rotors, calipers, pads (get new ones, and check the rotors for warping before you put them on), and brake lines from a 94-01 Integra (some civic models also came with the same size front brakes too, but I can't remember what they are).

REAR: trailing arms, rotors, calipers, pads (same story with pads and rotors), brake lines from a 94-01 Integra or 92-95 Civic EX 4-door.

E-BRAKE: Make sure if your car is a 4 door to get e-brake cables from a 4 door and vice versa, they are not the same length.

OTHER JUNK: most people recommend a 15/16" master cylinder from an integra to firm up the pedal. I still use my 13/16" because I'm used to it and I kinda like the pedal travel. You will want a brake proportioning valve stamped "4040" from any civic/integra equipped with factory rear disks.

:edit:On a different topic: If you already have a b18a running in your car, there is no need to buy a complete swap. You can re-use your axles, mounts, shift linkage, etc. You can even use the same transmission if you want (although the gearing will be too tall). All you really need is a longblock and ECU.

 

You should definitely consider buying a new clutch and pressure plate while the engine is out, its a cheap swap and makes sense so that you don't have to do it again.
