So I have read all the stickies about 4th gen B- swaps ( only about B16a no threads on the b16b) and specs etc etc etc. So here it goes,

I have 91 JDM Ef honda 4 dour civic. It currently has D series w/ 4-1 headers custom exhaust , cold air intake, DC Muffler resonator, Eibach lowering springs etc.

My question is how much further can I go on a D series. Right now i push 100hp
Or Should I swap it with the B16b motor w/ LSD Tranny ( I am thinking this route due to top end 200HP & 8500RPM redline)

If i do swap it what parts can be carried over.

Thanks

A B-series swap, as you shouldve read by now, is definitely a smart route for multiple reasons including the ease of upgrading it. But in order to give you clear answers you need to state which D-series engine you have.

Im also tweaking your title from "Read All stickies still ?'s 91 EF" to something more concise & helpful being that mentioning in the title that you read stickies is useless.
