Ulenrans '71 Build

[Ulenran]

Decided to fully restore my 1971 Super Beetle, taking it completely apart, rewiring, repainting, and rebuilding engine.

I will be updating this thread on my progress, feel free to comment with suggestions on what I should do while it's all apart!

Ripped apart, only thing left to take off is the windows, interior panels and headliner, and the engine.

Rear luggage tray, yikes!

Found that 72 steering wheel iv'e been looking for

By the way, what is this blocked off line coming from the left side DP?

pans are in great shape, just have to get all the adhesive off...

heater channels are good except for above jack points, metal there has flexed too much and caused small rusted out spots around 2 inches long above each side.

[Ulenran]

Got some more done this week, removed engine, seals, and insulation from engine bay.

Maybe you're already doing it - suggest bag and tag EVERYTHING and keep old parts too, even if right now you know you will be replacing stuff. I also sometimes put a little note in the bag to remind me later about something in particular. Also lots of pictures, these days with cell phones it's a breeze.

cleaned up and repainted air cleaner with high heat primer, going to do this to rest of engine tin when it is clean.

And here are the bad spots in my heater channels:

view through a hole in the right rear wheel well.....

gotta get all these spots clean so I can attempt welding, yay!

[Ulenran]

took the clutch out, discovered why I couldn't climb hills or maintain highway speeds.....

Also, my clutch spring seems to have been replaced. is it OEM or aftermarket?

getting my flywheel resurfaced too, it needs it!

[Ulenran]

Had some spare time to pull engine apart, found out I have an aftermarket header on the right side:

Left side is stock I believe.

Never seen an EEPCO head before. Had to look it up.

Decided to rebuild my engine into a 1680 with think wall 88s. Anybody build one here before? would like to know what a good combustion rating would be using stock carb (not switching to duals) with a cb2280 cheater cam.

Here's what I've got going for my 1680cc:

stock 34-pict 3 carb
stock crank
stock flywheel
stock rockers
2280 cheater cam
HD lifters
88mm thickwall slip-ins p&c's
Dual Port Cylinder Head, 35 x 32mm Valves, bored to 90.5


This will be my daily, and I have been trying to figure out what my deck height and combustion chamber cc should be in order to make a good compression ratio for regular 87/91 pump gas (USA)

anybody able to shed some light on the subject? The internet has information, but translating it to my engine has proven difficult or me.

Good plan. Original CR for a '71 dual-port was 7.5:1. Although I don't see a CR recommendation for the cheater cam, I suggest keeping it in the "high 7's" to 8.0 with the single carb. May need to increase the main jet size 1 or 2 sizes.

General aim for deck height is 0.040 to 0.060". If you look at the middle value 0.050", to get an 8.0 CR you'll need to have the head chambers measure at 52cc using the engine calculator from CB: http://cbperformance.com/v/enginecalc.html

Will you be using the heads now on your engine, or buying new ones?

Are your engine internals in good shape; will you tear the engine down completely?

[Ulenran]

I'm ordering new heads since mine are mis-matched and I don't have a good machinist anywhere near me, and I have yet to tear into the case so i'm not sure what I will find. engine was running decently before it was torn down, so I'm not too worried about it.

Thanks for the info!

Opened up the case, didn't find anything out of place. got it all cleaned up and ready for re-assembly!

Clean case, with a thin coat of silver paint.

New case stud seals installed

Main bearing dowel pins in place, left and right

Cam bearings in, left and right

Working on sanding the actual car to prep for paint too, engine will be ready long before it is though

As long as you have the time, and before you get any further down the road on the engine assembly, have you determined whether or not the case should be (1) line bored or (2) thrust cut? They are inexpensive procedures to clean up the bearing surfaces. Search it and you will find plenty of info on it, but basically start by seeing if your fingernail catches on the color deviation in the main bearing areas.

Been a while since I last posted, has to shelf the bug for a while to deal with other projects/problems...

Since the last update, I finished rebuilding engine and reinstalled it in the rolling shell that my super had become. Attempted to fire it up and all I got was cranking, no start. Turns out I had somehow made my engine a tiny bit wider, and my new stock length pushrods were not long enough to open valves fully.

Here is a picture of the engine being installed:

And here is the car now, with the body being taken off like I should have done in the first place:

Found some heavy rust in the forward 4 left and right pan to frame bolts:

the silver spot you see on the right hole is the sheared off bolt, which was very rusted.

As you can see, I have a lot of work to do![/img]
