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!

Finally got it driving over the Christmas break. Put in a Tangerine Racing firewall shift rod bushing and rebuilt the pedal with all new bronze bushing. New accelerator pedal and cable. Fixed my Pertronix Dist. With everything "hopefully" done i put in all the new carpet in as well. Aslo got my self a new MOMO Prototipo Heritage.

The rest of the interior can get done later and not necessary. But seat OBVIOUSLY need to be re-done. The back pad needs to be redone as well since there are two giant holes in it. Door cards need to be replaced since PO put speaking in them.

Radio needs to be fixed and speakers need to be put in.

Gauges need to be finished. Current set-up is my arduino on a bread board displaying on a little OLED screen. I have the design to make my own stepper motor gauges. Will have Oil Pressure, Oil Temp , and Cyldiner head Temp displayed.

However I have been driving it a good amount. Got about 350 miles on the new motor. Been super happy with it.
Final motor settings.
2056cc
8.6:1 comp
C25 Cam
1.8 Cylinder heads with 44mm intake and 36mm exhaust
44mm HPMX
60 idle jet
F11 emulsion
200 air correct
155 main (getting this in close. May step a jet size down still)

Holds a great idle @ ~950 RPM. Pulls great from 3000-6000 RPM.

Cruising on the freeway my cylinder head temps stay between 296-325 F. This is driving between 60-75 MPH. Also in the dead middle of winter so this is the coolest it will be.

Nice little 2-3 gear pull on an empty road.
