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

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!

As the updates come. I have bought a 2056 stroker kit along with a Scat C25 cam, scat lifters, and cam gear.

Still thinking about the heads. Looking at getting the AA 1.8L heads with the larger valves. Makes my life easier and my 1.7 Tins will still fit if I have read everything correctly. 1.7 and 1.8 tins are the same. 2.0 tins are different due to the change in spark plug location.

Doing the math with the flat top pistons, 58cc min combustion chamber, 0.036 piston to deck height, no head gasket. It should drop me just a hair under 9:1 compression. Should make for a very fun car.

Many miles of oil leaks and dirt

DIY hot tank, simple green, and a lot of elbow grease w/ a brush

Still some nasty spots but brake cleaner is going to take care of that.

I did assemble it empty and with some telescope gauges i measured out all my bores. Everything looks to be in spec with the stamping on the original bearings.

Another thing i have to do is think about what exhaust im going to use. Old one had to be cut up due to it being seized in some places.
May grab some stainless steel and tig my own up. It just depends how lazy im going to be.
