BP into auto aspire

[bhazard]

Picking up an automatic aspire with a siezed engine for $175. What's involved in swapping a BP in? Its an obd-I car.

The cars in beater shape but I'd like to get it running. Later on down the line I can Yank the BP back out and part/scrap it.

if it's OBD-I I bet it isn't much different than swapping into a Festy, other than it may be easier because I hear they have more room in the bay

Are the ecu's different since some had abs and airbags? Might want to check the connections first.

[Zanzer]

The ABS and airbags may have their own ECU's. That's the way many other cars are set up.

Well what about, say, the different maf/vaf connectors and such?

I got my info from nerdracing . You need the egt harness you will use the complete big plug side of that harness then splice like seven or so wires into the small side . He was building the complete harness for fifty bucks . He has all the info you will need .

I want to know how the auto does with the BP. I'd sure rather have a manual trans but a BP swap is quite enticing...

shadetree - not a knock, but I like your unique use of periods.

I was hoping Aaron would chime in. I know he did a BP aspire.

So it wont run on the aspire harness? I have a festy harness at my disposal too.

if your swapping a BP into an aspire, get a '94 miata ECU and the harness should match up pin for pin (except the egr valve which the BP and Miata don't have)

[bhazard]

Ok....that takes care of the ECU. What about everything under the hood? Sensors and such...use aspire stuff? Use Miata MAF?

[FestYboy]

miata MAF and aspire/BP everything else.

[getnpsi]

Can this be confirmed? Miata pinout and aspire pinout 1994-1995 are virtually the same?

[FestYboy]

i'll print out yhe schematics today and compair. DIY tune states the ecus are identical (except some driver pins and the tune)

[bhazard]

Eh I think ill just stick to a B3. Too undocumented of a swap.

I can do a harness up for you if you get a BP engine harness.
