Question about Suby ECU in a swap Options

[jasons]

I know its possible to swap an NA EJ25 SOHC using the factory ECU. Renegade sells a "Speed Sensor" kit. I think it bolts to the output of the transaxle. Is this required or optional?

I'm trying to understand the ins and outs of these swaps because I think they are interesting. I know a swapper could go aftermarket, Link or Stinger or whatever. I'm curious how much work it is to go with the factory ECU.

BTW, I've looked at most of the threads that are relevant. None of them really give a play by play on using the factory ECU. Just intimidating pictures with lots of wires.

$1750 for that e-bay motor is way too much, you should be able to get a complete non-turbo 2.5, 2000 or newer, complete with harness and all, for $1000. That one's being sold with the column as well, which may mean it has the immobilizer. No problem if you're using an aftermarket ECU, but something to avoid if you want to use the stock ECU.

Do a search for threads with '"speed sensor" subaru vw conversion' or somehting similar, because I think there's a way to fool the stock Subaru sensor with magnets glued to the transmission output flange. I don't remember where I saw it, but it was a cleverly simple idea. The stock ECU is free, so if you can spend time stripping out wires it's a great deal. If you can't or don't want to do that then you can pay Smallcar $300 dollars or something to do it for you. There are a couple of other companies who do it as well, so do a search. Still cheap, so that shouldn't be what holds you back.

Not that I've seen, at least shopping through front door sources like ebay, car-part.com, etc. I don't want to argue with you, I do want you to be right. But, what I see for $1k are usually DOHC motors. I'll keep my eye on CL or upullit type yards.

The few I've found locally through car-part.com were around $1600 w/ 28k miles, no ECU, no AC, No Alt. Thats why that ebay one looked attractive. If I were to put a radiator in a 914, I want to put a condensor in too. I would like to be able to daily drive the car, and in AZ its just not possible without AC

But That one's being sold with the column as well, which may mean it has the immobilizer. No problem if you're using an aftermarket ECU, but something to avoid if you want to use the stock ECU.

Good point, and I wonder if that motor has the throttle by wire?

Yeah Dana kind of described the same thing above. I just wouldn't want it to be a hack job.

Actually I think I just saw smallcar charges $650 for that service. I would do it myself. That kind of stuff doesn't scare me, actually I enjoy it, if I have the right information.
