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!

And we're back.

Had one major set-back. My brand new AMC cylinder heads had one of the spark plug threads messed up from factory. Only found that out when i was getting ready to put the new spark plugs in and start the damn thing up.

So pulled the head and put a Time-sert in there to fix the threads along and put it back in the car.

Then finished off the rest of the little things i needed to get done.
Trans output shaft seals replaced, shift selector rod seal replaced. Trans shouldnt leak any more (hopefully)

Made new mounting tabs for my oil cooler. PO just had it bolted flat against the trunk. Plumbed up the rest of the oil cooler lines. Headers are done as well.

Got the Patrick Motorsports Odyssey Battery kit and got rid of the old lead acid. Oil pressure, CHT sensor, oil temp sensor are in. Finished writing the code for those. Just need to finish up my Stepper motor gauge design and then I'll have a analog CHT sensor that doesnt cost an arm and a leg. In the mean time im just going to use little OLED displays just so i have some way to monitor them

All set up and the car is finally sitting on the ground after a long time. Going to try and fire it up this weekend.
