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!

Engine is back together. Had the machine shop remove some material from the bottom of the cylinders and set me up with a 0.038' piston to deck height. Putting it at 8.6:1 compression. Should work out great.

And in an effort to learn something new. Got me a beginners TIG welder and will be attempting to make my own exhaust. Stub pipes first. Should go about 11 more inches into a 2-1 collector and out the back with two yoshimura RS3 mufflers from a hayabusa.

Now to the shitty part. Cleaning up the engine bay from a splattered cv joint and god knows how many years of oil leaks. Got the falling apart battery tray out and got a good look at the rust damage. Doesnt seem too bad, mostly surface rust with some pitting but the hell hole seems to be on the same level and im going to be welding up those seems.

Since im taking out the non-working air conditioning i got to look at the longitudinal. Only rust there seems to be from them squeezing the lines through.

Fixing the front hole as well

Annnndddd to the rear fire wall. Some one tried to do a patch job and it was the shittiest job possible. Cutting them out and fixing that as well.

Ignore the blue that was the PO. Older gentleman only worked on the car a couple months a year use the color to help him keep track one what he did.
