Whats the most I should pay for a 13B-REW Motor that caught fire? The fire was pretty sever that ALL plastic parts are melted down + it has sat there for over a year.???

 

As long as the internals weren't damaged it should be fine. depending on the miles I would expect to pay around $1,500 to $2,000. Just need to get some parts off the for sale section or Mazda.

 

$1.5 to $2K? Seems a little high to me, for a questionable motor that was in a fire, and has sat for over a year. You can get a Mazda reman for $2k. I would say it's worth closer to $1K.

 

BTW this would probably be only the motor and the turbo's. Thats it. The wiring harness and all selenoids are obviously dead.

 

$500 would be the max

 

500

 

501

 

did you toast your car?

 

502

 

Nah, not me found it at a junk yard.

 

Buy it and make a new wiring harness, 500$ is very decent. There is nothing plastic on the motor (besides the oil filler neck, wastegate solenoid, and the coil packs) that you actually need to have a running engine.

 

How would I MAKE a new wiring harness for it??

 

With a lot of time, patience, and a factory service manual. All of the pin-outs are documented. There's really not that many wires to run on the ECU side of things (presuming you will be keeping it non-seq). I would think you may have to replace some sensors as well. Where exactly did the fire on the engine originate and what portions of it did it burn?

 

Also, with your own harness you can use a larger or two smaller junction connectors next to the firewall which will only require disconnection of your harness from those connectors when pulling the engine - instead of pulling the entire harness through the firewall.

 

Well I guesse your talking about all the electrical diagrams. Patience and Time yup I would need it. The fire Im guessing started where they normally do, the two rubber hoses in the back by the fuel rails. Either way everything plastic is melted in the engine bay. (up to the elbow).

 

Hmmmm.....I would agree that $500 is about the limit.
A friend of mine bought a 300 Z motor that had toasted itself (they were known for that) and it really is more hassle than what you might think. Luckily for him, my friend was able to use all the stuff off his blown motor and was familiar with the layout, and it was STILL a bitch.
I simply can't imagine trying to reconstuct/rebuild all the fried **** on an FD motor that had been thru a severe fire......

 

The hardest thing I would see would probably be the wiring harness. BTW you would have to (properly) mill the rotors for 3mm seals right?

 

BTW, there's really not that many wires for a non-seq setup:

For instance, everything you see splitting off to the right in the 1st picture is not needed for non-seq (this harness partially wrapped):

 

You dont even need the 2 boost selenoids if you run with manual or electronic boost controllers.

 

Yep, but with the way I'm setting up my solenoids, the PFC will be a fine electronic boost controller.

 

Well lets see the price he gives me, and I'll probably go 50/50 with someone on the project.
