BLU CIVIC · #1 10-06-2008, 12:58 PM

alright, looking at getting a B16, mabey, to replace my dead B18a1...now i what can i used from my B18a1 swap if i decided to get this B16? and can i keep my obd0 if i get a PR3 ecu?

or better yet, is it possible to get a b18b and make it obd0?

Just run your B18A1 dizzy and ECU, done.

Basically, its one of the simplest things: The majority of the time, just as long as you stick with the same ECU/Dizzy pair, you can swap it around to run what OBD you need. Ofcourse it won't exactly as intended, but it will run just fine with it. The main time there are complications with doing that is when VTEC comes into play because of the ECU.

i was thinking that but wasn't too sure

You won't have Vtec w/ the B16 if you keep your ECU tho... for clarity.

Also your fuel maps wont be right for a b16..but it should run.

should run slightly rich... about .2 liters worth of rich.
lacking Vtec, etc... but only until you get the right ECU and dizzy combo for it... and if you're sticking OBD-0, you just get the PR3, and sell the OBD-1 dizz for $75.

i kno i won't have vtec if i keep my PR4 ecu, hence my first question

K, so use the PR3, and use the dizzy from the B18, that will keep it OBD-0.

You won't need to use the dizzy if the B16 you're getting is already OBD-0 tho.

Or you could chip the PR4 and make it Vtec... or you could use a chipped PM6, or you could use the PS9 chipped and use the auto lockup solenoid (A8) for the Vtec solenoid... using the stock maps and only editing that one thing, then throwing some better maps at your topend (after crossover).

In short, you actually have a few options for OBD-0... use whatever one is best for you... probably the PR3 if you can get one readily.

Theres also the pw-0, but thats a jdm ecu and unless your engine comes with it you might not find one. I have seen them for sale and my crx ran one.

I love how you guys make it complicated.

Adrian, have you decided which engine you are going for?

at the moment it's a toss up between 2 different B16's, one that noone will get back to me about, a B18b that i'm waiting on an answer from, and a B18a that is a complete engine...if i get either of those i may end up with my complete B18a sitting in a corner somewhere
