EA81 (Brat) +EA82 SPFI intake stuff?
Posted 07 February 2005 - 08:41 PM
i know the theory behind putting EA82 SPFI onto EA81...
ea82 disty+ea81disty gear
ea82 SPFI manifold, wiring, ecu, O2 sensor, fuel pump, MAF, etc...
bolts onto ea81 block...
if i get it all to work, theoretically i should have good gas milage, and pretty consistant running right?
anyone else succesful with this conversion? any attempts and problems/reccomendations?
anyone have some good SPFI parts they would be willing to sell/donate to the cause? (I need wiring and ECU, and maybe some other good parts)

here's a pic of his setup

for the disty... maybe use an EA81T disty? that would bypass the need to modify an ea82 disty...
and yes, I will most certainly make instructions/diagrams/ info on how to do it if it works!

No dice on that one. The EA81T uses basically the same inductive pickup type distributor as the other EA81s

the two items are almost apples and bananas
EA81T --- basic inductive pickup used for creating spark only
EA82 SPFI -- crank angle sensor, the ECU uses it's output
for injector firing and spark control.
gear swap- inverted with new hole in shaft for locking it
Ear needs lopped off.
I have the entire package - planning on doing the convertion
this summer - I will try it on my 85 Brat.
My 86 is running so good with the Weber, I hate to mess with it.
Good luck please keep this post active.

im gonna go hit PAP this weekend.. see if I can gather parts there
is the spfi/mpfi/turbo disty different from one another? or does it depend on the year?

Try to get everything from a single car so you know that it's all the same.

the disty came from a 87.5 spfi wagon (same non flapper style)
the rest came from a 88 spfi, both wagons, both MT.
ECU part # is 22611AA392
I need to get the plug pin diagrams, so that I can hook up the harness to it. if anyone knows where I can get that, or could get it for me- that would be very helpful!
Im gonna see if the FSM has that info at work.. hope it will...

I have a FSM for I think 90 loyale series give me a call if you want to borrow etc
Posted 20 February 2005 - 11:25 AM
just my .0000000000002 cents
what did you spend on the ecu and stuff?
Posted 20 February 2005 - 04:00 PM
8.50 on wires
10.00 on ECU
21.00 on disty
so how hard , or what part is the hardest to do with megasquirt?
