New 914 Owner Options

[ogdougy]

Hello all!

Just making a quick introduction. Made my first 914 purchase just about two weeks ago now and now starting to dive into this car.

Its a 73 non-California car with the EB 1.7. 100k ish miles on it with a motor that is leaking like crazy (more on that later). Single 32/36 weber. Classic Auto Air AC unit. Fiberglass GT Flares, Empi Replica Fuchs, and a bunch of shit ripped out of the engine bay. Bout all i know on these

Next to my AE86 Track car that is currently getting a cage welded in
(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-26536-1652211033.2.jpg)

So now getting to the real stuff. I have worked on boxers before, i have an 400 HP ej22 on e85 in my Forester (that needs to get pulled, RIP transmission). But I have never worked on an air cooled one.

Right now, i have been doing some basic maintenance that i do when i get a car. Change all fluids, been changing all the hoses on the motor because they look like the original ones, added a catch can, etc....
But of course after changing the oil and pressure washing the bottom on the engine/trans. I notice this thing is pissing oil out the rear main. So i decided with the unknown state of the motor, im just going to do a rebuild.

Reading around its seems like the easiest thing is to buy a AApistons 19XX cc or 20XX cc kit. I dont have a horsepower goal in mind. I just want this rebuild and hopefully get close to the same mpgs i had with the 1.7 (30 mpgs on the highway driving between Phoenix and Tucson)

The end goal with this motor. I have an entire pertronix flamethrower vacuum dist with the correct coil and plugs. While the 32/36 works for now. I will replace them with 40 IDF webers. Then some new headers and exhaust. The horsepower I get is what I get. Not too big of a concern.

Q1: With my motor being a 1.7 i have to get the heads machined to fit the larger cylinders and some massaging of the combustion chambers to get the the compression down. Correct?

Q2: Cam choice. Do people run the original 1.7 cam or just get a "street/oem" grind from Web.

This was a long one but I look forward to what i can learn!

Welcome aboard

How is your new 914 currently running, with the exception of an oil leak or two? Could be a reasonably simple repair to get you along until your new engine is built. Will you be using your existing case? Good call with the Webers

If you are not using the stock FI, ditch the cam and get something more peppy. Make sure to get lifters from the same people that made the cam so they are matched in hardness.

Do something about the wheels. They look like aftermarket fakes, and they're too small for the fenders now.

Are you sure you don't want to swap in a subaru motor and transmission? (IMG:style_emoticons/default/happy11.gif)

It does fall on its face around 4K RPM. I believe this is due to the FI cam with a carburetor and dont exactly trust the tuning on the carb. I will be dropping the motor/trans. I could just drop the trans and redo the rear main. But there are some areas i need to weld up inside the engine bay. Hell hole is fine but battery tray needs to be replaced.

Probably get the most street cam i can get. But i will definitely get new lifters from Web as well. Thanks for that.
As for wheels, yeah its ugly, yeah they dont fit. But that is low low priority. The wheels work and roll. The engine will piss a quart of oil in no time.

I am down in Tucson.

You know why i dont care about power out of the Type 4? Because if i want power i have that ej22 closed deck motor.

Well during the tear down it seems like a bunch of decisions were made for me without my consent.

Every single exhaust stud/bolt was cross threaded. So now im not trusting a single ounce of work done by who ever worked on this before.

New motor, new heads, new a lot of things! Oh boy

Welcome to the PO crap work club. You might get lucky, but you are more likely right. After a while it becomes a game to see what the next special PO feature looks like.

BTW in southern Arizona, you might think about auxiliary cooling.

(IMG:style_emoticons/default/agree.gif) its a real issue and all sorts of (IMG:style_emoticons/default/bs.gif) its contantly found as you own/work on the car I have been half way lucky but now consider buying a car that has been worked on by a less skilled individual is a PITA.

Are you certain they were cross threaded? The air cooled motors run hotter than water cooled motors, I think overtime the exhaust bolts can get really hard to remove?


Air cooled is much simpler to work on than the water cooled, the main thing I found though is you have to keep on top of the oil a bit more and they want to leak more (IMG:style_emoticons/default/smile.gif). Also want to have oil or cyl head temp gauges to prevent overheating.

Some deeper wheels will make that thing look sweet, like my profile pic!

Welcome to the club. I would just add, if you are really looking for 30MPG and to regularly drive your car, build a stock-ish 2056 and put fuel injection on it with a mild cam and a good exhaust and call it done. It will run great and forever. (IMG:style_emoticons/default/beerchug.gif)

[aharder]

(IMG:style_emoticons/default/welcome.png) These are great cars to play with !!

[ogdougy]

Well I at least found the culprit. Someone was as new as I was to these motors when they worked on it but decided not to read about anything.

Rear main looks okay.

Flywheel oring is AWOL

As for the heads. I haven't looked completely in them. But one has already been helicoiled and that coil was NOT done right and is barely hanging on.

So more reading to do on what do actually build because the build budget is skyrocketing. Which is not that big of a deal. What has to be done has to be done.

Hey dude, helicoils have a use, It will get you home. For a fix I suggest timeserts. Really nice looking car, Welcome.

Or DAPO, hate to say it but over 50 years, the number of these guys is many. Looks like you are working through at least some of the previously completed "repairs"

You are 100% correct. They do have their use and when used properly, they work great. However im always weary when using them for exhaust stud repair due to the heat. I know people that have made them work in the exhaust but thats just my personal preference.

But installed properly is the key word. This one was not. You can also see the state of the threads on the other hole. Which is representative of all the other exhaust ports
(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-26536-1652888652.1.jpg)

IIRC this one had a large hex head bolt with a stack of washers on it.


But im still just googling/reading around on how these motors are built. All the possible combinations there are to get the desired size and compression.

[ogdougy]

I got the motor out and have begun to take it apart. Finding some interesting things that, i think, the PO didnt know about.

So first off this is a EB motor. 90mm x 66mm engine
(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-26536-1653185793.1.jpg)

But to my surprise it's got a 96mm piston. Not the best measuring but good enough for this
(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-26536-1653185794.2.jpg)

They are not salvageable unfortunately. Some bad scoring on the skirts
(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-26536-1653185794.3.jpg)


And the even more damage of the 1.7 heads
(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-26536-1653185794.4.jpg)


Im waiting on a case splitting tool to finish the rest of the tear down. Who knows maybe there will be an aftermarket cam in the case!!

But with this discovery I was pretty happy with how this motor ran, even in its poor state.

Will probably getting a new set of 96mm pistons and cylinders. New 2.0 cylinder heads. Adjust it for about 8.5 compression. Then make the cam decision once I find out what I have. If i have to buy one I think ill get the Scat 272 cam.

(IMG:style_emoticons/default/welcome.png) That's the worst install of a helicoil I've seen. Maybe the PO shot it in there with a Ramset gun. (IMG:style_emoticons/default/confused24.gif)
