Im not sure on the ecu, stock radiator will work, might need the modify the hoses or use the integra hoses, you can keep the fuel pump, use the integra shift rod and extension. I believe thats correct someone correct me if Im wrong. If your in need of a b18 complete swap, I have one for sale, let me know if interested

Make sure its from a 90-91 and it'll plug right in.

Under the heading
Basics:
All civic and integra OBD0 ECUs share the same plugs. Yep, so you can easily run a civic/crx si motor with a 90-91 integra ecu and vise versa. Plug and play.

You will have to use the integra's shifter rods AND you'l have to shorten them both by some 5-6 inches.

Well I assume you have a learning disability then. Then if you know soooo much, why did you ask the question?

I took a B18A outa a 90 Teg, pulled the D16 out and you know what?

Shifter on a Teg will fit, you simply have to shift it from in the trunk, so, it's your choice, bud.

Yes, you need to cut a section out of the shifter arms so it will fit. Trust me on this.

BTW, it ain't hard.

Sorry,

Yes, use the stock integra shifters, but modify them by shorting their length to fit.

IS that better?
