65 More Door with Subaru/Porsche conversion project
Posted by: azdave ()
Date: June 12, 2017 07:14AM

Yes. I bought another.

Some of you may have seen the 65 4-dr on Phoenix Craigslist that has been for sale for many months and was on ebay recently too. It has been converted to run a Subaru 2.0 turbo with a Porsche transaxle. The conversion has not run and was never quite finished because the previous owner developed health issues.

I towed it home just before the Tri-State Meet in early June and found time last weekend to put it on the lift to evaluate it further. It has rust and bondo repairs in all the usual places and the front floors have been replaced. It came to Phoenix in 2008 or so out of Missouri with a 110 and 4-speed tranny. It had a pretty nice restoration somewhere along the way but is now showing its age again.

I'll probably attempt to compete the conversion unless I find a fatal flaw along the way with the conversion. The fuel system needs re-installed and the temporary cooling system in place is just enough to prove out the rest of the conversion.

I found a few things to address with the conversion such as a cracked weld in the suspension tubing, a broken U-joint strap and a shift linkage that need some re-engineering. Nothing I've seen so far tells me this would be better to part out. I don't like the clutch linkage and would probably consider a hydraulic clutch if everything else comes together.

I've never worked with a Porsche transaxle or a Subie engine so I have much research to do. I think it has a Kennedy adapter plate but no idea what is inside for the clutch setup. The tranny is a 916/63 5-speed and externally looks to be in good shape and the fluid is clean. The engine came most recently from a sandrail so who knows the condition inside but he did say he had the engine running at one point. It turns over, the oil is clean and the anti-freeze looks good.

He had begun adding a new larger fuel line to the engine and converting the original fuel line into a fuel return. The gas tank is brand new and it came with three different high pressure fuel pumps for testing.

I found other minor issues like rear brake shoes reversed and a disconnected e-brake. Since I bought it for less than the value of the tranny and the engine I figured it was a low risk endeavor to pursue. Time will tell.

Now I need to start studying up on the power plant components.

The definition of bitchen Dave!!!

Digging the cradle style rear mount.

I'll bet I know where that weld crack is.

Hydraulic clutch only way to go with the 915.

I see plenty of room for an EZ code six cylinder.

Looks like whoever performed the swap knew what they were doing to maintain the rear suspension geometry.

Nice ride. Personally I would buy it for the drive train and suspension mods. Then put it in a LM 500 2-door car. Then sell the 4-door to someone for parts. That would be nice. I believe those engines can be tuned to output ridiculous HP. I also like the 6 cylinder idea but why not run this one for a while and see how much fun it is.

They have oil pans that are shortened for the buggy crowd . Might be a good idea for that car.

Looks like a 2.0 to me. The 2.5 turbos have variable valve timing. Still an easy 300whp with a few bolt ons and a good tune. An intercooler would be a must have though. That's a pretty good size turbo.

Thanks for the tips and suggestions. Yes, it is a 2.0 and I'll try to complete the build as it sits for now.

If all goes well, I've considered moving the conversion parts to a 2-dr chassis (I have a few of those around) but that's thinking too far ahead at this point.

Rod, thanks for the link and oil pan info.

One other thing that caught my eye is with the half shafts. One is installed with the slip joint outboard but on the other side the slip joint is inboard. So far, I can't find a reason for that other than a mistake during installation.

Cool factor of this one is off the charts!!! I'd love to have that. (I work at a Subaru dealership).

Did some research on the engine management system that came with the deal. It looks ancient by modern standards. Since this engine came from an old sandrail I'm sure that it was simply transferred from the rail to the Corvair.

So far I'm not really finding much info online but I haven't tried to get archived docs from Electromotive yet either. It might be a better decision to go with something more popular and modern so the online support is there instead of fighting to learn the old technology. Up to now I've only done ECU re-flashes and piggy-back systems and even that has been almost 10 years. This would be my first standalone.

The ECU currently has a serial cable dangling from it so you can plug in your Windows 95 laptop. smiling smiley

There's no rush to make a decision on the engine management since I've decided to pull the engine and be confident about the mechanicals of the clutch/flywheel setup and get the shift linkage sorted out better. The clutch cable will work for testing but is almost sure to get converted to hydraulic later.

Craig piles on: I was thinking the same thing. Looks like there are lots of little things to address but the heavy lifting seems to be all done. Not a bad looking car either. smileys with beer

The Electromotive.system isn't a bad system. It is still more than capable of supporting a lot of power. But it lacks a lot of features that modern stand alone systems have now. Self tuning, individual cylinder correction, internal boost or methanol controls, data logging, etc.

This is awesome! I would definitely keep the 4 cyl since it is lighter than a 6 and can still put out plenty of power.

Let us know when you get this running and out to a Cactus event or Pavilions. Would love to see it.

I don't know if I believe that this engine is lighter, but it does look like a cool build!

for reference an EJ20 like the one in this car is 350~ pounds and that before you fill it with water or attached the radiator!

What a great project and find with so much done already.thumbs up

It seems a lot of projects get close but not finished. Too bad the previous owner had health issues that prevented him from seeing this finished. But at least you will have the chance to get it running and test the conversion.

Very cool and in good hands. Thx for pics.

The half shaft confusion is the sort of error I would make!

Took about an hour last night and prepped to pull the powerplant. Not a lot to disconnect with wiring. The lift is in place and all that remains is to remove the half shafts and rig up an engine cradle for when I lift the body up out of the way. I really need to pull it to fix the cracked weld properly.

I will split the engine from the transaxle and see how things are in there. The seller mentioned he was not 100% confident the clutch was operating properly so might as well be sure what is in there. I'm pretty sure he used the KEP adapter kit but we will soon see.

The PO didn't do too bad running the new fuel line but anyone see a problem with the shift tube mod? grinning smiley
