Frank's mpfi/obd1 swap list
 

I would like to compile a list of things I will need to do this, if I do this.

I have a stock 91 civic std (d15b1/dpfi/obd0)

I don't know which im/tb/dizzy/ecu etc i need, so if anyone knows I can start looking. :rolleyes:

missing anything here?

b7 im
b7 intake arm
b7 tb
dx dizzy
p06 ecu
ecu plugs


thanks guys.

You look good, there might be something I'm forgetting, but nothing too serious, I ought to write it up one of these days. Wish I had my camera with me, boo my foolishness.

You can use any old IM/TB, but to match the ehad best I would use DX stuff. I happen to have an obd1 dx IM laying around, :p

Ben, do i need a chipped ecu or a dx ecu (p??)?

I'd be interested in buying your im if i cant find an integrated im/tb.
is the wiring a pain? what is the easiest way? buying a new harness? :o If I want to modify my current wiring would that be hard or much more time consuming? Thanks!

p06, wiring is easy, use the old hardness, you need to and it's easy.

Cool. Is it neccesary to go obd0>obd1 in order to do an mpfi swap?

What is "ehad" and is there any benefit of using the dx im as opposed to a cx im? Anything wrong with using the 88-91 b8 im or the 92-95 b7 im? :rolleyes:
maybe mpg diff's b/w the dx and cx? would i then have to use a diff ecu?

You don't need to go obd1.

The DX IMs will match your intake ports better, and the b7 IM is prettier than the crx/civic si one.

if the b7 (same as b8?)im lines up, fuel efficiency wise which im should i go with? do you know if i would run into probs with the b7 im not lining up well enough?

b7 is DX, b8 CX. I'd use the b7, because the b8 will have ugly air flow. *shrug*

cool, I am now starting to read on h-t about mpfi swapping! :cool:
