In reality tts probably just the same if not more efficent and easier to just swap the gearbox over from the Crx to the Civic.

i got the box but i think its crushed or sumthing coz i can only start the car wid the clutch in, also do i need to change engine mounts or fuel lines i mean ive got every thing spare from the crx i just need to know every spare part i need from the crx to put on the civic, does anyone have a link to a project one that somebody else has done before that i could research, thnx every one for there help.

is the d15b gearbox a s20 ? If so will bolt up to your d16a motor

that would work out perfectley if it is a s20 the civic is a 91 so what ever gearboxes they come with.

you gearbox code on your gearbox would be on a sticker by your front mount it should fit thou as d16a / d15b use same motor casing just different bore holes

if you are changing from the D15 carby to the D16A EFi you will need to change the fuel lines, and fuel tank for EFI. I thought about doing the same think as i have an ED at home and just got a 90 CRX, but really, SO much work to do to convert it. hope that helps and doesnt dull your spirit :) have fun the little ED would go awesome with the D16 in it

yeah that will be awesome, you should be able to with no problem change the fuel tank and lines over from the CRX as they are the same floorpan and same dimentions. should be really good, let us know who it goes.
