so about a month ago I bought/traded for a 72 914. a little rough here and there but a nice dry car.
the goal is to turn it into an improved car for auto-x and short track use (streets of willow) while still keeping it street legal and semi-tame.
for now I decided to stay with solid rotors to keep the budget under control.
so the brakes will be BMW in the front and stock ones in the rear.
I'm going with Koni sport shocks all around with a used Weltmeister front sway bar. I picked up a set of new 21mm front torsion cars and I have some 165lbs/in for the rear. yeah I could go higher spring rates in both the front and rear but the roads around here aren't too smooth and my fillings are loose.
here is some pictures of the work so far.

this is the new suspension next to the old stuff we took out.

here is a detail showing the zerk fittings we put in the front control arm mounts.

here is the rear suspension arm after boxing and with zerk fittings added along with new bearings and 5 lug conversion. I'll trim the studs after we get the rear wheels mounted and spaced to fit the GT flares.

Attached Image


here is the new rear suspension installed in the car. we left off the brakes as I will be taking the car to have the chassis stiffening kit installed. less work for the metal guy to remove the rear arms.

while the suspension work progresses I'm working on another engine for the car. right now the car has a stock 1.7 with FI. I bought a 2.0 off eBay that was local and ended up being reasonable. I also picked up a set of Weber 40IDF's for it.
the 2.0 won't go in the car until I get a side shifter trans sorted out for the car.
right now I need to get a set of front hubs cleaned and longer studs installed.
Cheers,
Kent

Looks like a good start to a nice project! You might want to add the sale items to the classified section. Admins are lurking.....

I have a set of magnesium minilites that are powder coated silver. 7's for the front and 7.5's for the rear.
I just ordered a set of F/G flares for the car. My son and I like the pop-rivet look.
The car is dark metallic green right now. Originally it was silver. We both like orange 914 race cars.

progress:

lots of work is now done and the car is running again.
installed a Porsche ignition tumbler set from a parts car I picked up.
BMW calipers, adjustable front Koni's, poly graphite bushings all around, 21mm front springs, 165 rears, boxed arms, powder coated suspension, new master and flex lines, Koni rears, front sway bar still needs to be installed.

interior is gutted.

right now we are running 6.5 aluminum Minilites in the front and 7 inch Magnesium Minilites in the rear.

projects next up: Lexan rear window, brake bias valve, relocate the battery to the rear trunk.

oh yeah I'm picking up a fresh race motor and a side shifter.

forgot a picture of the aluminum door panels I made.
I'll top them off with the rails from some early door panels after I get them powder coated crinkle black.

i did something kind of sneaky.
i had some 69 912 struts left over from my son's 912 after we put SC stuff on it.
so I used them with some 912 hubs. then i bolted stock 914 rotors on the 912 hubs. that combo puts the rotor in the correct position for the calipers. you have to use the hubs for non-vented rotor for it to work out. the calipers are 320i BMW that I got off the web.
the a-arms are 912 so i used 911 21mm springs and 911 spring adjusters since i used an SC aluminum suspension bar.

i was going to use 912 rotors but they are a little larger in diameter (i was going to cut them down) and a little thicker (used ones are the same thickness as fresh 914) but i ran out of time to turn down the OD and went with the 914 rotors.


just tried to use parts i had laying around the place.

I wondered about that. Some early 911s had solid rotors as well.

Very cool, using what you had on hand.

If you are tracking the car I'd suggest plugging/blocking the head vents, enlarging the case vent, and using a better breather (I never liked the CB one when I ran it in my drag bug).

My car "ran out of oil" when it was "full of oil". I pumped everything I had in to the heads and starved the bearings. Doesn't happen often, but it does happen...

Nice job on the trailing arms. You will love the bearings!

Think about throwing an oil cooler up front for track work. Really makes a big difference in temps and engine life.

Rivet flares are good. (IMG:style_emoticons/default/beerchug.gif)

the engine came with a nice cooler and remote filter but they were mounted to the engine. I'm going to move the filter to the bulkhead and put the cooler up front. I'm also going to run a deep sump and an Accusump to make sure the engine has OP all the time. I used to vintage race a 356 so I know about oil starvation.


been looking for a good exhaust system, didn't think finding a good one at a reasonable cost would be so hard.

been a while since i posted any work.
here is my oil cooler setup under construction.
i mounted it in the back with 2 fans, using a large cooler i had sitting around.
i also mounted a catch tank.
i have a gel battery that will be mounted in the trunk, it isn't shown as i was working on the oil filter mount that is under it.
you'll see what what is going on when i get everything mounted in place.
as you can see i found an exhaust system. 1 3/4 as my engine is 'large'.
the little bracket is for the brake bias valve.
i should have some finished photos this weekend or next on most of these projects.

Kent,

Give us a heads-up when you plan on going out to Streets of Willow. I'm 50 minutes away; it's my home track.
