hey i am about to swap in a 1994 b18c1 into my 1994 si civic hatchback which came with a singlecam vtec d16z6,

i have the following AND ONLY THE FOLLOWING nothing else
1994 si hatchback engine harness
1994 si p28 chipped ecu
1994 si timing belt mount, tranny top mount, tranny lower bracket
1994 gsr ac bracket, rear mount, shift linkage
1999 b16a2 transmission, starter, axles, halfshaft
GSR skunk2 Manifold

seeing as that this is all i have, what do i need to buy or do in order to run this motor at 100% please consider knock and o2 sensors, also consider the engine harness is for a single cam and the motor and distributor etc.. is a 1994 gsr

thank you for your time

You also might want to remember the GSR manifold with the dual runners. either take them out or set up your vacuum hoses to work like the GSR or they wont open at WOT. Or just get the Skunk 2 manifold and eliminate the whole thing.

EDIT: You can use the o2 sensor off the gsr manifold, or off your manifold as long as it is 4 wire. Just screw it in w/ 7/8 wrench and plug it in. You will need to extend your wires to reach around the back side of the motor and drop down by the rear motor mount to where the o2 sensor connects to the gsr exhaust manifold. This is much easier to do out of the car, and much easier to just extend the wires connecting to the o2 sensor, not your actual engine harness. Do not worry about knock sensor for reasons stated below.

I used my stock civic shifter in the gsr linkage. The feel is a lot better. Also you should cut off the counter-weight on the end of the gsr stabilizer bar so you do not get any metal-on-metal noise when shifting. Lets see... you will probably need the gsr/b16a2 lower front tranny mount. The stock 94 si one will not work. If you do not have one, or cannot get one, here a suggestion:

Take the actually mount off of the a/c bracket, take the actual mount off of the 94 si lower front tranny bracket and swap them. The mount is much more solid on the tranny side, this will help if you only have the a/c side hooked up because the a/c sides blow easily. Now when swapping these mounts, you will need to use both washers (one from each) on the new a/c mount and probably one more washer might be necessary for spacing it out right.

Now your stock a/c compressor will not bolt up on the gsr a/c bracket. If you do not want to lose your a/c or have to deal with flushing/recharging your system, then here is an option:

Get a CRV a/c bracket and use it. Your stock SOHC compressor will bolt right up, so you will not even have to d/c it. You can also use a 99-00 Civic Si a/c bracket and modify it slightly (i think cut off one part that is obviously in the way when you bolt it up, I've never done this though so I'm not sure the exact location). CRV bracket from honda is like 130$, dont know about ebay or junkyard price. I've seen a hasport bracket too somewhere once.

You will not need to worry about wiring up these:

IAB (because you have skunk2 manifold)
Knock Sensor (because chipped P28 disables it, or at least it should)
EVAP Purge (it isn't necessary)

Since your car was setup for vtec, you should be good to go.

Also the rear motor mount, leave it alone. Just use the bracket on the B16a2 tranny. If all you have is the stock 94 si bracket bolt it too the tranny, it should work, it's the same. When dropping the engine in, hook up the two side mounts (one by timing belt, one on top of tranny) then use ur hoist to lower/raise motor onto back motor mount. The bracket for the back motor mount should be completely connected to the tranny, tightened, and all you will have to install is the one bolt that goes through the actual back mount. If you have any questions, hit me up. Hope this helps you.

Reason I switched shifter is because the GSR is all curvy and feels wierd in car. It's a little wider in the linkage but just use some washers in there to space it out w/ the 12mm bolt. Just be careful not to bend it overtightening.

thanks that was very in depth, however i'm confused on a couple of things,

first, are you saying that i should not use the gsr rear mount???????

second, are you saying that i cannot use the d16z6 tranny front lower bracket on the new b series transmission???????

third, is there more than one o2 sensor?? i thought it was just one o2 sensor which goes to the exhaust manifold, on the d16z6 it was on the front of the header, on the gsr it is on the bottom near the cat, i know i have to extend that one but you mentioned something about the knock sensor in your first paragraph so i was confues because i didnt know if you were talking about the intake manifold or exhuast manifold(header)

another thing, i think i lost my o2 sensor, so i might have to buy a new one should i buy a gsr o2 sensor or a d16z6 o2 sensor since my engine harness is from a d16z6????????

thanks again for replying

no you can use the rear mount, they are identical, but if the rear mount from your 94 si is still mounted to your firewall, leave it, it is less work. Either rear mount bracket should work on your tranny

second, are you saying that i cannot use the d16z6 tranny front lower bracket on the new b series transmission???????
yes, you cannot use it, at least in my experiences, just hold the bracket up to the tranny and you will see the 3 bolt holes on the tranny do not line up with the 3 on the bracket. This is for the front lower tranny bracket, a little left of the slave cylinder.

third, is there more than one o2 sensor??
no there is only one, sorry for the confusion, you will just need to extend the wires to reach the new location.

another thing, i think i lost my o2 sensor, so i might have to buy a new one should i buy a gsr o2 sensor or a d16z6 o2 sensor since my engine harness is from a d16z6????????
either one, just make sure it is 4-wire o2 sensor.

thanks again for replying</TD></TR></TABLE>

sorry for my confusing statements.

Paulnsx

good info i'm hoping to do a similar swap in the spring

bboylito

thanks again you are the man, one last thing does it matter if i get an ob1 or an obd2 sensor???

To be honest I do not know if it matters, just get a 4 wire o2 obd1 sensor and it should work. Sorry for my lack of knowledge.

bboylito

lack of knowledge??? haha dont make me laugh you have 12 posts and have answered all of my questions so i tip my hat off to you

bboylito

anything else i need

bboylito

ok this is what i'm still consfused with, the chart from the helms says that i should use the integra mounts but that i should use the civic rubber pieces maybe someone can clarify this for me in a b c terms SORRY

I used a EX mount (like you) on a LS swap in a EX. I maybe wrong, it was like 5 years ago.

You should be allright with your timing belt mount if it looks identical (3 bolt holes in same location).

Now on the a/c mount bracket, the rubber is breaking. This essentially means the mount is screwed. Look at the picture above. take the mount(rubber part) off of the "right front mount" of your civic (since it will not fit the b-series tranny).

Now in the photo where it says "retain the civic rubber mount" put the rubber mount from the "right front mount". You will need a total of 3 of those washers that belong on there (you will see the washers I'm talking about when you remove the rubber mount. If you are confused, just look at the ones in the picture under the "left front mount" photo, it is the only washer in the picture.

Using these washers will line the mount up with the body.

The right front mount is a helluva lot stronger then the factory a/c rubber mount. I've been running this on my gsr swapped ej1 for a while now and it is holding up fine. I found out this little trick because my threads are stripped in my tranny for my right front mount. A local honda guru told me to just use the a/c mount with the right front rubber, works better. You know what they say, better rubber, better protection. j/k

hope this helps.

Here is a link with TONS OF PHOTOS for the gsr swap into eg/ej civic:

http://www.c-speedracing.com/h...p.php

concepts the same for most b series motors.

bboylito

thanks that helps a lot guys, so it seems like all i need is the actual right rubber mount that attaches to the tranny and keep the part from the civic that attatches to the chassis, and i also need the same part for the left side,

so my timing belt mount looks good??? it has 3 bolts

bboylito

lol haha i found another problem the gsr motor that i'm swapping in was previously in a 1996 ek civic coupe and it seems that he had to change the timing belt bracket that is bolted right onto the engine is different from what it should be or is it????

the picture with the red valve cover is what came with my gsr, and the picture with the pulleys is of a motor that came out of a 2000 si notice how the gsr bracket is round and the b16a2 bracket is squared off, so i'm confused

GSR


B16a2

Turbogixxer

That bracket is off a 99-00 SI, you have to use that bracket for a EK. You need a integra three post mount.

bboylito

thanks do you have any idea where i can get an integra 3 post mount? junkyard? how much? because if i go to my junkyard the guy is going to tell me to give him an offer so i need to know how much they are worth
