New member all the way from MTL,Quebec!

About 10 days ago my brother and I bought ourselves a little project car, an AP1 S2000 that had a little electrical problem supposedly caused by the battery relocation one of the previous owners had done. It doesn't run at all so we got it pretty cheap at 4.5k, the only missing bits was the door sills which we've already found. The guy had had it for a few years, bought it burnt and never had the time to work on it. Its a 2001 yellow S2K far from its original home in Florida. It was supposedly turbocharged and functioning when it was imported, a few years down the road it had a little fire and the insurance claimed it as being a complete loss. When I say little fire its because the only things that we've seen that actually need to be replaced are a small section of the wiring harness on the passenger side and pretty much the whole HVAC/Heater fan systems, all of which has been ordered. There's also a part of the carpet that melted up in the passenger foot area and a few marks on the dash and door panel which will buff out

Now here is where it starts to get a little weird, the car supposedly has a "modified low compression setup" engine from an AP2 (160PSI in each cylinder) and while striping it down we found out that its hooked up to an H23A ECU...
Has anyone ever heard of this being done?
Best case scenario in my head is that the guy who had it turboed parted out all the turbo bits including the original ECU and put it in as a placeholder or that it might even work??
Worse case scenario is that it might have been turboed but that the engine is completely shot, that the guy put in a H23 ECU in it so that it wouldn't be able crank and that he'd able to pass it off as an electrical issue seeing as the car has some melted wires

Either way, the interior was stripped in a few hours, dash, seats and every single piece of carpet, some of which had melted and glued to the floor. We're planning on getting up and running, passing the inspections and then depending on if the car actually has a low comp block either turbo it again, or in the case that its shot, swap it out for something bigger because everyone likes a good old LS swap right

On a side note, my brother also has a 2008 AP2 that's in working condition so we could easily test for the ECU if we have too.
We're not in a rush to have it fixed, my brother started his own company and I'm at school but even with the little time we have I expect it to be on the road next summer!

 

Bringing it home

Really hoping that this is actually a low compression setup

Burnt harness on the passenger side, this thing goes all the way to the back of and connects to the fusebox, so we've ordered it all together

Putting the bumper back on after cleaning the whole car 4-5 times to get rid of the years of dust

Melted HVAC/Blower and sadly the OBD port

Dash marks not sure if caused by weather or fire

No more dash, no more bash bar or whatever you want to call it and all or most connectors separated.

Are you sure the ecu is for a H23A, what does the model number on it say?

 

It’s at my brothers house and these pictures are the best that I’ve got, it says H22A so oups on my behalf for that. I can ask or possibly go see it tomorrow and confirm!

 

Cool project but looks like a lot of work ahead to get it back into decent shape. Good luck. $4.5k is about as cheap as S2000s get regardless of mileage, condition, and whether or not it runs (I've even seen some for sale around that price that had no engine at all).

 

My guess is someone took the AP1 ECU or whatever standalone was in it and kept or sold it.

The H22 OBD2 ECU on its own is pretty useless, cant be chipped or flashed, has an immobilizer. Highly doubt it was being used to run an F22C.

H swaps in other OBD2 cars are easier done by using an OBD1 ECU; More than likely they had an OBD2 H22 ECU laying around from a previous swap and threw it in there expecting insurance to be none the wiser.
