The tool du jour (IMG:style_emoticons/default/smile.gif)

Bolt stretch gauge for the ARP bolts. Homemade of course.... (IMG:style_emoticons/default/biggrin.gif)

With ARP bolts you can torque them, but the recommended (for 3.0 rod bolts) is measuring for .010" of stretch.

Note I checked them with a torque wrench, the ARP recommended torque was .010 stretch.
So i wouldn't be afraid to use the torque if one didn't have a strech gauge.

Had to do a quick check to make sure there was no issues with my crank gear change, I'm going from a CCW dizzy to a CW dizzy and I'm using a 2.7 dizzy crank drive gear.
I've be told a 3.2 gear is slightly a different size and can cause issue, but this one seems to work just fine, not to tight or too sloppy.


Altough I took this gear off my 2.7 crank it is the same gear as on a type1 or type four engine. It even had a VW logo stamped on it. (IMG:style_emoticons/default/shades.gif)

BTW this was before I totally cleaned the crank and for this check I didn't care about the orientation of the #8 bearing..

Sorry I couldn't do a better set of pic's on the build up, but once you lay down the sealants you only have maximum of 45 minutes till the case has to be torqued.

But.... (IMG:style_emoticons/default/w00t.gif) (IMG:style_emoticons/default/smilie_pokal.gif)

Looking Good! That's a good feeling to get the case closed up.

Another thing, I noticed your running a single pulley, is it an older 126mm? I just put one on my car (vs the stock SC 136mm) and it slowed the fan down some it runs a little hotter at idle now, I'm going to go back to the larger pulley.

I didn't measure it, but it's the one that came with my 3.0 core and it is quite a bit larger than the two 2.7 and one 2.0 pulley's that I have compared it to.
edit:I get an OD of 134mm and it does have a 930 part number. I'd rather not replace as it is balanced to my engine.

Time to start thinking about the next phase (IMG:style_emoticons/default/smile.gif)

Pistons, new Mahle, 3.0 RSR, Goetze rings
Cylinders, stock 3.0 nickasil, replated Milenium/LN engineering.

I'll still have to DFL coat the skirts, and ceramic coated tops,

I'm not sure where these originally came from, guessing they may be leftovers from a racing program. They also might be 2nd's as they were a hair under size for stock 3.0 jugs. That issue was fixed in the replating spec.

So between kidney stones, dealing with my kids problems, my mom taking a tumble and the bad boy below I've fallen behind on not just the 914 but all my project.

Hopefully I can catch up but I won't have a bunch of time to on this site this summer.

I did get some more headwork done.
Took me a while to get my head surfacing jig sorted but in the end it worked real good.

Nice!

What are you doing for intake port sizes? Are you going to run carbs?

Good choice on the heads. That's what I have in my 3.2 short stroke!

Nice! If you're looking for weber 40mm ida's, I have a nice pair already tuned for a 3.0 (it atleast should be close for yours). They were rebuilt a few years back.

Oh good, you may want to consider 36mm venturi's if you're going to rev past 6000 much, I guess you can get it together first and then decide. I also installed the AEM 02 sensor. Its great for tuning, but I found that these carbs like to run rich in almost all rpm bands that aren't WOT.

Can't wait to see it done! (IMG:style_emoticons/default/driving.gif)

Too much life in the way so progress is slower than hoped, but progress never the less.

Heads done, mild P&P, new valves, guides including a trimming the tops and Eibach springs.

P206 spring setting tool (far left) made life easy.
