So I came across an old '75 Porsche 914 1.8, I figured I'd try and assemble a few collections of pictures as I tried to get the thing put back together enough to get it on the road, with the long term goal being a Subaru EJ20/255/257 swap. Here it is as it came off the trailer, covered in dust, dirt, bird poop, and all in all looking sad.

First step was to give it a ~very~ light pressure washing, the seals around the Targa Top were worn and the windshield isn't even secured in place. Here it's sitting open, airing out the bit of water that did make it in. The original color was red and the previous owner had decided to give it a gold top coat.

The drive train was separate so first step was to pull the intake, exhaust, and the shrouds off to make sure the engine wasn't a ticking timebomb waiting to overheat. This is the 1.8L flat 4 motor with air cooling, and one of the heads already removed, showing the modular cylinders.

Just checking out the pistons in the bores, making sure that there was nothing catastrophic wrong with i-...wait a minute, what's that?

That deep gouge in the bottom right, what happened there? Did one of the valves hit it? It's a push-rod engine so there's no way it could be a broken timing belt, let's take a look at the head to see what could have ha-...

Oh...oh no...

OHHHH NOOOOOOO...One of the valve seats fell out and was just bouncing around behind the valve, smashed up the aluminum head and punched a dent in the piston...dammit, time to round up a new head...that was it for this weekend, just familiarizing myself with the vehicle and what it needs. 10/19/2014.

I actually want to see the end result, +1.

I'll do as much as I can to get it rolling under its own power as soon as possible!

Umm... You can still hammer the valves with a broken timing belt/chain in a push rod engine. Mangled 3 of them in my GTO years ago.

Or in a generation 3 hemi for that matter. Guess how I know :)

uhhh, I'll take 'personal experience' for $100 Alex....

Well true, but more what I meant is that the camshaft in this engine is a simple 2:1 gear-driven drive off the crank, no belt/chains.

No Problem. Thought you meant that the push rods bend (which they do...) not valves, but with a high lift cam the valves can hit pistons.

I've seen bent pushrods from a 7L Volvo Diesel motor that overrevved when the Allison tranny decided to downshift going down a hill...Ugly.

Don't fail us with updates now on progress. I'm doing the same to a 1969 Plymouth Roadrunner so I know what you're going through :)

It's basically going to be updates as I can afford them. I just noticed this morning the engine access panel pull-cable is rusted through.

Update 2: Engine arrived! Looks fantastic other than chipping paint on the intake. It's been attached to the 914 transaxle. Pics soon!

Since you've requested an update, new engine has been purchased and is on a slow boat from China, a 60,000km EJ20K WRX STi Motor.

Hopefully soon, I'm basically taking this on blind, so the more I can learn with the stock engine, the better I'll be when it's swap time.

I've been looking them over, probably going to modify a Subaru transmission to convert it to 2wd and remove the rear output.

Why? over complicated.

12 years ago | Likes 2 Dislikes 0

Because the stock 914 transmission clocks out, goes home, and retires after about ~260lbs/ft of torque. EJ257's can make 300+

Keep it up! I'm really interested in seeing the progress!

It'll be a slow process...it's old but popular, so parts are hard to find and expensive.

Well, time for an ls3 swap.

I thought about it, but I don't know if I want to do what I'd need to handle 400+ hp and find a transmission to mate it with.

whatchu talkin' bout? I forgot those transmissions suck.

12 years ago | Likes 1 Dislikes 0

Not too many transmissions that'll work given that it's a mid engine with the transmission facing towards the rear, and side-outputs.

Convert to an ls4 then. fwd v8. That'll do it. Goddamn mid-engines ruining it for everyone!

Makes the weight ratio nice though.

Or.. call Hennessey and ask for the trans out of the Venom GT. You're welcome!
