Uhh-Ohh…., My Ongoing 914 Build Adventures.... Options

You need to look at the build as part of the fun.

This is "fun" when my guy gets here to put this lump back together, and we start with the serious stuff.

Supposed to be this week "sometime." Uhgg.

I did make a pretty big offer on the '66 911, she is thinking about it.

This cost me six weeks. I know the /6 Porsche engine will be insane and fun, but if I had this to do all over again, I wouldn't have done it.

I have been at my engine for about 3 months now so I feel for ya but remember one important thing and that is you are doing it yourself so it WILL take longer. The ugly alternative is pay someone. Nope! I have been held up several times for various things and suffered some set backs but like you said it "will be insane and fun". Difference is I would do it again.

Keep at it it will be worth it. Got the timing set over a week ago then had family in for 10 days. Timing was a big hurdle for me and now the real fun begins finishing it up.

Hopefully this pic will provide some inspiration. I was where you are just a couple weeks ago.

I feel you on that. When I think back to how long my car was off the road, how I felt in the midst of the conversion, and how I've felt as I sort it, I think I should have kept it a four.

Then, last Saturday, while I was driving the car from Emeryville to Berkeley, and listening to that overhead-cammed flax six behind me rumble, then sing through PM's Dansk sport muffler, I was soooooooooooooo glad I did it. The car feels, yes, insanely special in a way it never did as a four. And it sounds absolutely sublime—right up there with the best sounding Porsche's I've ever heard.

Good luck.
I can't afford a 66 911 and send my kids to college but I'm trying to get the 66 912
Sort of funny that one of my kids roommates has parents that are (not exaggerating) billionaires.

Are /4 steering shafts longer than /6 shafts? This is a "future project" that I have been messing with whilst waiting for my engine to come to life....The four shaft seems way too short.

[Larmo63]

The heads and manifolds are back, too. Build day is supposedly tomorrow. I'm not holding my breath.

What year? I think the early ones work for the conversion 70-71 but not the later years 72-76. But there is a recent thread or 2 about the conversion as well as sir andys thread

Here you go, snapshot from PET. Late would appear to work

Put the engine back together today and clearanced the case a bit to install the Clewett crank fire system pulley...It was very satisfying to make some progress.

Nice ,what are the main benefits of crankfire as opposed to all the old tech or even pointless setup,just asking cause TBO I don't really know.
Lawrence your head guy came in fast,did you go to bigger valves with the porting? see the inlet manifolds opened up,nice.

[Larmo63]

Valves were fine, we opened up the ports to 36mm to fit my cam profile a bit better. We did a few other small "tricks" too.

The Clewett system is easy, (very) hot spark, and "set it & forget it" timing.

Precision. Distributors have some slop in them; the moving parts cannot move without a little bit of it, and they will wear so the slop gets worse. With no moving parts, a crank-fire system will always give you the spark at the point where you call for it.

Wear. A reluctance sensor pretty much does not wear. Distributor points wear, changing dwell and timing. Even if a pointless setup is used, the distributor parts still wear, leading to more slop as above.

Flexibility. Basic distributors only "know about" RPM. So you get the same ignition timing at a given engine speed, no matter what. More advanced ones can be hooked to manifold vacuum, and possibly to a ported vacuum signal, giving the distributor some information about what is happening to the throttle. A crank-fire system is computer controlled, and it can read every sensor in the car if need be. It can alter the timing based on RPM, throttle position, manifold pressure, engine temperature, and even on recent history. If you know what you're doing, that can help get the most from the engine. (If you don't know what you're doing, it's more ways to get things wrong.)

I have the longblock assembled, and today I set the fan/alternator on for the final time. Hooked up Perry Kiehl's EXCELLENT main wiring harness, and installed the fan shroud. Manifolds are on, this thing is real close to going in. It's been a long road, I've learned a lot, and it feels good knowing that this is the final assembly.

One issue I did encounter is with the fan belt installation, it seems too small. 10 x 710....

Anybody know the correct size I need?

[euro911]

9.5x710 or 10x710 should be correct. Did you move any shims between the pulley halves yet?

[Larmo63]

My outer pulley half is a 96mm part. I have scoured to inter webs to figure out what larger size fan belt works with this set up. Why is this so tricky? I like the pulley I have, why isn't there an easy way to figure which larger belt fits?

On another note, I bought three cases of oil today along with two bottles of Lucas zinc additive. 20w 50 oil.

I'm getting serious now.

Figuring it out is easy as Pi (IMG:style_emoticons/default/rolleyes.gif)
