Ah, I see. Na, I am trying to get the tac signal from the distributer and send it to the Porsche gauge cluster. I would hope that the signal from the GM distributer is pretty light, but IDK.

When I was testing the wires a few months ago some of them, when put to ground through the multimeter (just testing for voltage) would give a blip on the tacho. ME THINKS that means if I give some of those wires a blip from a tac signal off the distributer they will make the little Porsche tac come to life.

This is what happens when you have the plug wires in the wrong spot and your engine says "CHECK YOUR TIMING" and you are like "F YOU I'm gonna pour more gas in the carb". Oh well I really shoulda clear coated that adaptor plate anyway.




And I picked up a piece of garbage on the side of the road today... then I put it on my car.




Well, I was thinking that air, being a fluid, would find the vacancy in the engine bay of my car the path of least resistance... then slap a Z-art top over that vacancy and I'll get all kinds of rumblings that I don't want. SO I wanted to make a belly pan of sorts (to keep that naughty air going out the back of the car). I found a washer machine on the side of the road near my house and I picked it up. Fits pretty well, I just need to do some trimming and paint. BUT I think its gonna do well back there. It fits under the OEM plastic trans tunnel (??) panel; so I don't think any excessive air is gonna really find its way into the engine bay.

BUT at the end of the day I know its just gonna look like I have a washer machine under my car. ROTFLMAO

Dunno if that will work for you guys...

She's on the ground and I charged up the A/C. Now its just a matter of fixing a 2007 Mitsubishi Eclipse before I can back the boxsterado out of the garage. My wife's car warped the head and is currently blocking me in; gotta fix that first.



It looks so mean when its off the jack stands.

Yeah, looks sharp! I loved the belly pan solution, very genuine

Further in the saga of LISTEN TO WHAT YOUR ENGINE IS SAYING. LOL

Yeah, roots blowers don't allow for backflowing of gasses. Apparently I've been running on 5 cylinders ever since I first started the engine. LOL

I'm not mad, I'm actually impressed. That push rod made it through a rocker.

Oh well. In about an hour and a half I had both the heads off stripped and I'd ordered new headgaskets, rockers, and lifters. God I love this engine in this car, its like insanely easy to work on. Everything is so easy to fix and right there. Imagine having an engine on a permanent engine stand with 2 feet of room to work on either end; that's a SBC in a Porsche.

Ahhhh yeeeeah; She moves. BUT got some questions...

The DME apparently does NOT like this situation. The A/C doesn't click on because the computer doesn't think the engine is running (oh boy its running LOL). So I have to hard wire strait from the climate control box a wire to the A/C clutch. Does anybody here know off the top of their heads which wire kicks the A/C on?


Also, cause the computer is not getting all the info the cooling fans aren't coming on... Thats an easy enough solution. I'm just gonna get a thermo switch and hard wire them. Not really looking for an answer here; just sharing


And third problem. The Porsche designers didn't make the throttle cable long enough for an edelbrock carb. WHAT WERE THEY THINKING???!! LOL



Other than those issues... its fun. Just fun to be out of the garage finally. Even though I'm happiest when in the garage.

For the A/C: there are at least two points where you can hotwire the system: the A/C pump relay, and the A/C control unit. Based on the circuit diagram probably you can trick the control unit such that it thinks the engine is running. Do you have the Bentley service manual? I`m uploading the respective diagram here, just in case, I hope that`s allowed:




Hope that helps.

Hmm.. Looks like it got resized, I guess you can`t see the text. I can send it to you in the original size, that`s readable, lmk if you need it.

Got it.

I think I'm gonna try giving the crank angle sensor some voltage from the tach wire. I'm hoping that might trick the computer to think that the engine is running. I think that might cure what ails me.

If not I guess I've gotta wire stuff up.

Last image dump.. The body isn't gonna change much at this point so picture viewers can sign off now.

I have the "tuning top" on the car right now. It makes it soooooo much easier to make carb/timing or other tuning changes when the hatch isn't on the car.

OK sitrep I have cooling fans when the engine gets up to temp. The problem is the fans cool off the radiators... and the radiators are 2 meters from the sensor. Maybe some day in the future I'll wire up an electric water pump to turn on when the fans do. That way if I shut the car down the fans won't run FOREVER. ATM I wired them to turn off when key is in the off position.

There is NO power to the relay 2 box. I'm gonna try to hot wire the relay 2 box tomorrow. That might give me A/C voltage.

As for the tac... I'm still up in the air. I think I might honestly just get a Porsche CAS and glue a picup sensor to my flywheel. Kind of a jerry rig situation, but who cares.




Anyways, she is lookin suuuuuwweeeeeet. [You're supposed to read that with a good southern inflection]

















PS: yeah, I know that right fender is fubar... the door is questionable.
