Project Porsche 914 Update

tomrichardson · 06-12-2001, 04:14 PM

I now have 3 Porsche 914's.

My blue one (1973 1.7L)
My yellow one (1970 1.6L)
My black one (1974 don't know displacement yet)

I'm going to completely finish stripping my yellow one tonight. I have most everything out of it, engine, interior, lights... etc. Tomorrow it's going to junkyard to be crushed.

I just bought my black one today for $350 from CoPart. It's hit bad in the front. The engine has performance equal length exhaust system and two Weber-like carbs.

My blue is going to be the car I'm going to keep. It's going to turn into the actual project car. This week and weekend I'm going to take the engine and transmission out of the black one and put it into my blue one. This will put me to the point where I will be able to drive the car to work and so on. Going to strip whatever I can from the black one and get it crushed also.

Engine:
I picked a 2.0L VW type 4 case, crankshaft, rods, and flywheel two weeks ago. I ordered 103mm jugs and pistons. Going to get the case machined sometime next week. Stock bore for stock pistons on that engine is 94mm. So, I am waiting for my pistons and jugs to get here so I can take it to the machine shop and get the case machined for fitment of larger pistons and jugs.

Len is going to Pamona, CA this weekend to see if he can pick up a cam and heads.

Bore: 103mm
Stroke: 71 mm (stock)
Compression ratio: 7.6:1 (stock)

With this information, I can calculate my total displacement.

Cubic centimeters = (Bore x Bore x Stoke x .7853 x # of cyl.) / 1000

(103 x 103 x 71 x .7854 x 4) / 1000 = 2366 cc

2366 cc = 155 cubic inches

1 L = 61.024 cubic inches

Which means my lil VW engine is going to be 2.54L.

If I can get my blue one running with the engine from the black one this week... I just may be running it this weekend at the auto-x. I'll do crappy, but oh well.

More Later,
Tom

with all the money you have for all these cars i could use some to get by with till i get a job or.... you could go to the denver DUMP a motocycle salvage yard and get me the fairings i need the fronts and lower. and a front tire fender cover too. thatll be it.

Tom, what are your final goals for the engine of this car? Are you going to build it up as a natty monster or is there a way to stuff a nice autocross-sized turbo in there?

-Jon

tomrichardson · 06-13-2001, 10:03 AM

Final goal is so be an extrememly fast street car, and an occasional race car for SCCA sactioned events.

I'm pretty sure I'll be sticking a medium-sized intercooled turbo setup in there.

I want to be puting about 300 HP to the wheels.

Here's a link to the 914 racecar I've worked on. It belongs to a buddy of mine who races it in POC/PCA events. He's definitely one of the faster guys out there. I'm mostly responsible for the aerodynamics and chassis welding work. If you have any questions just let me know!

Holy shiznit!! That car is f***ing awesome!

That's even the color I want to paint it... Porsche red. Nice job!!

I will definately have some questions for ya later on! Thanks!!!

Tom

tomrichardson · 06-13-2001, 10:53 AM

I've even got some question for ya now!

Is that a 914-6? Did you put on the GT flares? How hard were they? What size wheels (width) were you able to fit in the front and rear? What kind of coilovers are you running the back? Did you keep the torsion bars in the front? What sort of transmission? Stock?

I've heard the stock 914 transmission is awesome... Lucky for me through my travels I've acquired three stock 914 transmissions in full working condition.

Thanks!

Tom

Blackskull · 06-13-2001, 12:55 PM

Heh... I thought my friend was nuts with his 3 914's...

Only 1 is working though... he may have spare parts if you ever need any.

email me if you want to get in contact with him.

my email: den1@asianavenue.com

jerome02rs · 06-14-2001, 01:33 AM

Tom,
Pretty neat huh?
Yep, it's a six. 2.2 liter, about 220hp. He had a four in it before but they just don't last too long in racing trim. His previous 4cyl. motor actually stripped its cam gears, which is pretty severe. The new 2.2 is a nice compromise between power and durability. Changing to a six is definitely the way to go and it's really not that hard. You can even go upwards of 3 liter displacement.
The flares are original factory steel . The car as you see it in the photos is no more- a new widebody kit was just put on that allows for 10'' rear wheels (275 tires in the rear.) We added more chassis reinfocements as well.
The rears are Carrera coilovers and fronts were just changed to coilovers. The front struts had the spindles raised to lower the car without radically changing suspension geometry. The car is definitely stiff- you'd have a hard time getting it to move while pushing down on the fender. It sits pretty darn low too- the roofline is maybe waist high.
The trailing arms are boxed in and their mounting points are tied into the engine mount beams.
The front end has a big chromoly hoop that extends from the secondary front wall to the front suspension pickup points. There are reinforcing plates and curved triangular gussets down there as well. Those were pretty tricky to weld in! Try TIG welding upsidedown while still controlling a foot pedal- you get the idea. The back end has the towers tied into the roll cage with additional plates welded in for reinfocement of the towers. They are also now triangulated all the way back to the rear swaybar mounts and the sheetmetal above the transmission (a 915 I believe) has been cut away.
We molded the oil cooler ducting ourselves. It opens from the airdam and seals up to the front of the cooler. Then the ducting leaves the cooler and splits going up and over the fuel cell and exits the hood. It works extremely well. There is a transmission cooler in the rear as well. Also added was fresh air ducting that gous from the roof of the car and through the rear window to the engine compartment. All windows and windshield are Plexiglas. The roof has also been chopped 2" in the front and the windshield extended out a few inches.
The rear wing is carbon fiber with aluminum endplates. The first wing we made ourselves (I'd have to check my airfoil info- maybe NACA 4415) and it produced some serious downforce- apparantly more than my rough calculations estimated because it came apart at Road Atlanta at about 140mph. The wing was literally torn from the endplates. Oops! The new carbon wing seems to have solved this problem. Most everything on the car was done by ourselves with no budget and a lot of ingenuity. You'd be amazed at what can be done to a 914- they're definitely underappreciated.

tomrichardson · 06-14-2001, 01:45 AM

Whoa... maybe someday we can race that car and mine head to head, eh? That'd be cool!!

Thanks for the information!!

Tom Richardson, Jr.

JJTheSubeDriver · 06-18-2001, 09:25 PM

If I recall correctly there was a 914 at this weekend's autocross. It was yellow, that's about all I know about it.

Here were his times:

CHRIS DEWHURST, N > 43.199 <
73 PORSCHE 914
1) 46.188 2) 43.727 3) 43.199 4) 44.592

For comparison, my best time was a 37.768

tomrichardson · 06-19-2001, 12:53 AM

You tryin to say my lil Porsche is a hunk a junk, eh?!

We'll see!!!!

:P

ImprezaRS dot com · 06-19-2001, 03:20 AM

Yes, Tom, he is telling you that

My RS did a 33.682 and a 33.819 on the re-run because the car in front of me left a cone layijng on the course on my fastest run

Instead of winning stret mod by a 10th of a sec, I made second by 34 thousandths...

Good luck with your 914

tomrichardson · 06-19-2001, 03:58 PM

Well, just so you know, the max HP for a 73 1.7L 914 is around 80 ponies at 4500 RPM.

My project engine (big bore + turbo, 2.5L) should put out about 300HP at just over 7000 RPM.

Not to mention I'll have adjustable coilovers for front and back.

It'll be a lil different picture.

Tom
