PMB Performance - Project 914 ORV!, Yup, we're building a 914 for Utah's backcountry... Options

[Eric_Shea]

We've been playing with this one in our spare time. I don't think I ever put an official thread up here on the site so, here goes!

This piece of crap will soon become "Project 914 ORV". Actually what looks pretty bad on the surface; is pretty bad "on the surface".

As many 914's go, someone tried to make this one something it isn't. It isn't a "slant nose" no matter what you do to the fenders. And, I don't care how many Miami Vice episodes you've watched, that rubber whale tail thingy and the rear reflector are just plain "wrong".

But wait... Speaking of "just plain wrong", were going to carve this late model, big bumpered version of of 80's lust into a high-rise, fiberglass skinned, tubed tub that's ready for Utah's backcountry. That's right; White Rim Trail here we come!

Fear not, we're still thinking "all things vintage" so, we'll be pouring over factory rally pictures and builds to make sure we can learn all we can from the engineers at Porsche who went before us.

Here it is as it arrived:

Time to get busy. Shovel loads of crud came out of the trunks and interior:

Ooooh, the comedy never stops when you're working on a 914. Farm and Fleet tractor implement lights silly-coned on for turn signals! Yee-Haw!!

Off come the body panels. Special thanks to Elli-rot who went before us. He sent a bunch of pictures of his Dzuz fastener locations and offered advice on where to put them as we cut the panels off. Here you see pictures of his cars taped to the body as we taped and cut. (IMG:style_emoticons/default/wink.gif)

That there's a good 1 1/2" of Bondo. (IMG:style_emoticons/default/lol3.gif)

Nice solid tub is what we were looking for and it appears that's what we got.

Here you can see what we're aiming for. All of the QRS panels from Jeff are laid on the car in a mock assembly. Already looking 100% better! Next it's off to sand and soda blasting.

Eric - glad you've done the fronts now too. Any chance those will be available for us to purchase?

Hey George, Thanks.

Yes, I'm going to get a set of arms and run through a few "Best Practices" scenarios before I launch them onto the market. I need to get ID measurements correct and LOA with both bushings loaded in their respective end caps and on the car. I have all of the conical washers as mentioned earlier as well. I want to perform a full non-binding install and get pictures and make notes.

Mark, these are very hard bushings with little give so, they can't be made to "force" into the arm like the softer ones. Some fit very tight and some are snug. You want the bushing to remain stationary in the arm while the arm itself rotates on the shaft. The shaft has to remain proud of the bushing end because it gets torqued to 85-87 ft lbs. on the outer side with the mount and 108 ft. lbs. on the inner suspension ear. Those knurled ends dig into the body mounts and figuratively make the shaft one with the body while the arm rotates on the shaft. Any excess side-to-side movement and you'll get slop, noise and odd handling. Any looseness on the shafts and you get rattles and squeaks.

"Most" bushing installs require JB Weld to either install their precise races (Elephant) or their bushings in general. It's those variances you mentioned in your previous post that need to be overcome and with these rear arms, I've found the arms themselves to have the largest variance.

Elephant has a nice method of supplying a sleeve that is a looser fit to the arm (like these) and then makes the arm precise to their bushing ID. That sleeve needs to be JB Welded on though. I may utilize sleeves for my fronts. Still thinking my way through it. The variance, again, will be the arm itself. Some may be rusty stock old paint "get'er on the road" fixes. Some may be powder coat. Some may be paint. That's where the sleeve can come in handy. "Do what you want but, put this on before you put the bushing on..."
