ok. i just finished my RHD conversion on my 1990 civic hatch Si. i did a firewall swap. the rack and pinion bolted on just fine and so did the streaing coloum. my problem is, my rear tranny bracket doesnt align to the rear mount. its off buy a whole lot. i got the left and right motor mount bolted on but the back dont align up. does anyone know what im doing wrong? help meee! here's some pics of the rear mount.

i just want to know. since my EF clip had a B series motor in it, do i have to change that back rear mount? what do i have to change to make my D series motor fit?


here's a pic of the rear mount. as you can see, its off buy a whole lot.


this is the bracket that im using. im not sure if i have to use some other kind of bracket...

does anyone know if there is a difference between a b-series rear mount and a d-series? cause im not too sure..

 

My thinking, without ever doing a RHD swap

I think the problem is, if you went RHD with just the firewall / interior / steering rack swap you have changed the mounting point from the one of SOHC motor to a DOHC motor, that's why all the other mounts still work except that one.

If you went RHD with a whole front clip swap -- firewall --> headlights -- than I have no clue what's going on with a SOHC.

the same thoughts here. Is the new rear crossmember from a dohc car but the rest of the front sohc. this is probably the difference

 

So let me get this straight, you have USDM mounting brackets in the front, and a JDM rear crossmember is JDM? And you want to put a D series in?
IDK about JDM rear x members, but on the USDM ones I've encountered they had 2 mounting points one for the B mount and one for the D.

 

i did a EG conversion and all the mounts bolted up just fine. i compared and measured the LHD and the RHD crossmembers and they seem to be the same. im not sure if its the mounts on the motor or what. IDK

 

But as you know, the EG chassis shares the same mounts between the B-Series and the D-Series, that is not the case in the EF chassis.

 

so do i have to change the mount on the crossmember or do i change the bracket?

well did you have the engine in there before or is this the first time putting it in? if its been in before just use the old X member if their the same.
I dont understand though what you mean by you did an eg conversion?

 

i bought a clip with no motor jsut so i can do the RHD conversion. i bought the motor and trans soon after. i ment that the LHD and the RHD crossmembers are the same as in the position of the rear mount. it just seems as if my motors too much to the left for some reason. is their something im missing or doing wrong?

your still not making sense.
an EG is another chassis model.
If you just did a RHD conversion on a ED/EF (88-91 Civic) then you did nothing involving a EG.
what engine and tranny are you using?
Did you look and see if there are other holes to mount the rear mount on the x member?
like I said, mine had 2. one for D series, one for B. If I recall, the D series was on the left.

 

does everything else go together smoothly.. how do the axles fit into the hubs.. is the passenger side a bitch to put in?.. maybe you have the wrong mounts making it shift toward the passenger side.

 

yah my sedan had two, one was used with the automatic transmission, the other was used with the manual transmission.

i know that EGs and EF chassis are different. im jsut saying that i did a EG RHD conversion and everything bolted up just fine. ill check for the other holes. maybe there are other ones. thanks for the help tho. ill keep u guys posted

i cant make it shift to the passenger side. the left and right mounts are bolted on. i havent had a chance to put on the axles cause i cant get the rear mount on. does it matter if my RHD crossmember is a 4 door? is there a difference??

so your telling me you used a EG RHD clip on a EF chassis?

hahaha naw man. forgoet i ever said i did a EG RHD. nevermind. my question is, "if my clip had a b series motor in it and im gonna put a d series motor in it, would i have to change that rear mount? is a 4 door EF crossmember different from a EF hatch?"

 

He means he has done a RHD conversion on a EG(on en EG) before and there was no problem. Now he just did a RHD EF(onto an EF) conversion and has those questions about the mounting about the EF.

 

im looking at my rhd crossmember and compared it to another usdm . you will have to move the mount over to the left more to use a d, but its missing the hole for it.

 

u have a welder just cut the rear mount

and weld a plate to make it work

Now that this is all clear this is a simple ?

If you used the whole front RHD clip, mounts n all, then your problem is the DS mount is placed different than the USDM one (or so I've been told)

What VIN number is on the firewall? you can identify what chasis it came from off the VIN

 

you simply got like a automatic rear mount...you just need to put a D manuel that is a few inch on a driver side!

 

your problem is the rear x-member is a B-series x-member and it IS different than a D-Series X-member. even if you were to use a B-series motor, if you ever used a Motor mount 'kit' for B-series you would have the same issues because the kits are based of the mounting point of a USDM x-member (JDM already has B-series stock, therefore never needing these 'kits'). Also, I remember reading someone's post that did a K swap to a RHD CR-X EF8 and ran into the same problems because all mount kits are made for USDM chassis/x-members. Just my observation, i may be wrong....also if it is automatic x-member then you are in even more problems.
