It would be a travesty if anyone over the age of 20 in this country didn't.


I am and I dont, so it must be a travesty. (BTW, I don't want to know) I know you guys out in CA have your own lifestyles, and it's none of my business.


Nice project by the way. It should be interesting to see it all work out.

And nobody picked up on the term "travesty" from the German "Travesty Cabaret".

Alright, I'll stop with the obscure tranny jokes and get back to work...

Alright, engine and tranny are out for a while. Waiting on parts and have a LOT of work to do on the chassis. So back to rust abatement we go.

Anyone know a good howto thread on removing the motor tin shelf that runs along the long?

If you're removing them for good / not trying to salvage the shelf, I found it easiest to use an angle grinder and/or an air die grinder with a 3" cutting wheel to grind off the spot welds -- much faster than spot weld cutters. And if done slowly/judiciously you won't have to fill in the little circles left by the cutters.

Just grind the area of each spot weld until it is paper-thin, then carefully pry it away. Easy-peezy, especially after you get the hang of it.

It's been a couple hours and nobody replied, so I improvised with the grinder, seems to be my default. You don't want to know what happens when the wife leaves me without direction in the bedroom.

Seems much of my near future is grind, weld, grind, weld repeat until dead.

Ok, things are going slow lately. I'm not as mobile as I'd like and it's cold as hell in the shop. Some progress though, I managed to find cheep off the shelf axles for this conversion. By sheer luck, the driver's side axle off an early MKII Golf is a perfect match after the thickness of the flange adapters on the tranny.

One less thing to worry about, it's been nagging on my mind.

More parts arrived today. I've got an airbox!

Problem is it's too damned tall, this isn't gonna fit under the engine lid:

On the up side it didn't cost much and I've now got a plug to mold something that works. Who's dumb idea was it to put an Audi V8 in a 914 anyway?

Alright, I'm shelving the v8 for now. I know, sad news and all. Just too many details to sort out and still get this car running this spring so v6 it is.

Got a little sidetracked, had to build one of these for the wife's goats:


(IMG:http://www.914world.com/bbs2/uploads_offsite/i910.photobucket.com-9685-1334522798.1.jpg)

Took a while as I couldn't drive up there, with all the rain the clay soil turned to grease. Had to hump all the materials up that hill by hand. Happy wife happy life, what are ya gonna do?

Anyway, back to car business:

Ordered a new clutch and pressure plate Friday. Turns out the PP from the 30v v6 bolts up and has an integrated 60-2 trigger so that makes that part easy for the MS install. It's dual mass so I can use a solid center clutch from Kennedy and not get that "snap" that normally happens.

Lately there's been both time and money. This never happens. I just wasn't happy with the motor mounts I made so this happened:

(IMG:http://www.914world.com/bbs2/uploads_offsite/i910.photobucket.com-9685-1334522798.2.jpg)

Now to wait for paint to dry and gut what's left of the interior...

After a little blasting, that hell hole isn't so hellish after all. I'm gonna toss some more metal in there shortly just 'cause.

What size square tubing did you use? With all due respect, it looks too light.

Sure, now that it's done you want picks?!

Sadly, I forgot to replace the pilot bearing when I put it together, guess it's coming apart again. Pics to follow.

It does doesn't it? 1" 12ga obviously doubled on the laterals and stitch welded with 1/2" solid diagonals on the forward mounts gusseted..

The math works out, the mount points will recover from a 500lb pressure deflection. Since the engine is only producing about 300lbs (ish) at those points all will be well if I managed to push some decent welds.

I agree though, it LOOKS dainty.

I agree though, it LOOKS dainty.

Doubled horizontally (as compared to a single 1" square tube), the deflection is roughly cut in half.

Doubled vertically, deflection in this case would be reduced by a factor of 4.

There will be a lot of different forces at work. My concern is the basic vertical load. A 500 lb static load may result in deflection of 0.1" and a max stress in the range of 10ksi. A shock load (speed bump, railroad tracks, pot hole, etc.) could be 5 times that resulting in stresses higher than the material (and welds) can handle, especially when repeated.

Your design may be perfectly fine, I can only comment based on the picture and information given.

All I know is it looks Orange (IMG:style_emoticons/default/confused24.gif) Holy crapola we have some smart teeners out there. You actually did the math & engineered it? For a messed up build that has nothing right. Sounds like you know what your doin (IMG:style_emoticons/default/unsure.gif)

Don't get too excited, this is somewhere between rocket science and "hold my beer, this'll be cool".

Plenty of time and decisions left to screw everything up.
