B16A FAQ

**Canemode** · 18-07-2007 11:57 PM

Hey, I did a swap last year into my ED Civic hatch of a B16A Gen 1. I swapped everything, wiring looms, dash, motor,tranny,frontend drive shadts brakes the lot. It all came from a 1990 EF9 SIR Jap Spec half cut. It has been great but over the last month the wheel bearings, CV's and gearbox have all pretty much died. I put new wheel bearings and CV's in it and discovered that these are the same as on a 1989 prelude, which seems to make sence given the bigger motor as they are all heavier duty than the original ED gear was. My question is what is the best way to replace the box since they are rare to find for the B16A. Can i get a 1989 B series box from a Prelude or should I try to find the original box or should I consider repairing the current one. Any advice or ideas or suggestions where to go would be greatly appreciated.

hi im currently looking at doing a b16 conversion to my 89 da9. Was just wanting to know a few things. Will i be able to use all my original parts from my b18a like drive shafts, shift linkages, air con, radiator, wiring loom and just add a few more lines for the vtec, alternater, waterpump, engine mounts if i was to buy just the b16a gearbox and ecu? Also will i require a engineers certificate since i am dropping in displacement from 1.8 to 1.6? Also what engine would you reccomend me since my car is OBDO? b16a1 or b16a2 as i still want to stay cable style clutch?

The Gearbox you have on your B18 should bolt straight onto the B16A because all B motors have the same gearbox compatability. Your choice as to which one you do. I am not sure what drive shafts are on your existing car but they may or may not be compatable with the B16A gearbox I do not know it is dependant on shaft size and number of splines. With my car I had to do all of it because my old gearbox was not compatable and then the old shafts were not compatable with the B16A gearbox and so on, so I did the lot. But I was swapping out a D15B motor which is not a B series motor so that is why. Also the B16A1 is a cable clutch so this should be the same either way. As for the wiring I replaced the whole wiring loom to avoid this hastle so I can not help you there. I dont know for sure but I suspect all the front end should be Ok to leave as is if you use your original gearbox.
Engine mounts I am not sure about for that swap but you can buy engine mounts aftermarket to suit if you hunt around. This is what I did, plenty on ebay in the states that works out economical. Same with linkages. If you decide to keep your existing gearbox let me know, cause I am looking for another gearbox for my B16A and would be interested in doing a deal for the B16A box if you decide not to use it.

will i require a engineers certificate if i was to swap a b16 into my DA which currently has the standard B18A in Victoria?

I dont know but suggest you ring and ask main roads so you are sure.

hey sorry to revive an old thread but im really confused with my engine lol the guy i brought it off put a b16a in it and on the recipts it states its out of a 93 del sol but when i look at the engine its only a b16a, so does this mean i have a jdm b16a with 125kws or a standard 118kw? and also wat obd would i be running

Look for the engine number etched on the engine block.
If it says B16A, then it is jdm. If it says B16A1, A2, A3, etc... it's not JDM.
DelSol should be OBD1 just like other EG, someone to confirm.

wiki says

Engine(s) D15B7 1.5L 102 hp I4
D16Z6 1.6L 125 hp (93 kW) I4
B16A3 1.6L 160 hp (120 kW) I4
D16Y7 1.6L 106 hp (79 kW) I4
D16Y8 1.6L 127 hp (95 kW) I4
B16A3 1.6L 160 hp (120 kW) I4 1994-1996 OBD1
B16A2 1.6L 160 hp (120 kW) I4 1996-1997
OBD2

which says that it doesnt use a b16a

yet wiki also states
The VTEC trim level (called the "SiR" in Japan and the "VTi" in Europe) was added in 1994 in the United States (The CR-X Model in Japan had the B16A engine with 167 hp (125 kW) though),

which says that it does use a b16a

lol this is way 2 confusing thanks for the help but
