I went from this https://www.youtube.com/watch?v=LmvyscXRCNU
to this https://www.youtube.com/watch?v=g1GG2t8xn7M because GSF forgot the AFR bung I need for checking the tune. Plus I cant MOT the car with zork anyway but I just had to test it first.

I know which I prefer.

There's hope for you yet, bro!

BTW - Paul is slacking - I woulda' thunk that he would have seized the opportunity to post a pic of his Garretson-superior, ginormous, better than Viagra intercooler . . . could pull from the 20+ other pictures that he's posted of it, tha' gloating (or is that "goating" ?!?!) beech!

So now we are posting idle videos??? Guess I'll join in - a tad rich with the current heat.

Considering swapping out the hooligan for an outlaw over the winter.

The car lives! And although there are the expected teething problems, overall things are going much smoother in the tuning department than I'd expected. Given the car hasn’t been tuned beyond a “finger in the air” conservative ignition map, and using an AFR to dial in the Leask, I’m impressed.

The positives:

• The car sounds AMAZING. The Zork and K27-7006 make for one wicked sounding combo - much more like a nasty, big cammed NA race car than a turbo. Literally the best sounding 911 I've ever heard.
• The other question mark that has been resoundingly answered in the affirmative is the cam choice: 993SS cams are a winner! With twin plugs and 8.3:1 CR, power delivery off idle is way better than my SC and the power curve is sweet, with a nice rush on top.
• The other question marks, the suspension and brakes, also passed with flying colors: the car handles and brakes great.

And now, the Negatives:

• No blinkers...kind of not safe to test drive, as result.
• No driver's side window controls...I can't even hand signal to turn!
• The turbo still leaks oil . Not as much, but it leaks.
• There's a MASSIVE boost leak. The car doesn't register boost unless you hammer it and won’t register boost at all on a slow roll or at constant RPM.

The biggest concern is of course that the turbo still leaks. We are going through some troubleshooting steps right now and hope to have it sorted shortly. The boost leak is no fun, so we are going to have to make sure that the BOV is operating as expected, as well as to confirm that the boost controller from the ECU is functioning properly. The blinker...probably a relay or fuse (hopefully).

So the jury is still out 48 hours before departure for Rennsport. If we can sort out the above issues, the 930 will go. If not, the ‘66 will get another return trip to Monterey instead. We'll keep banging trying to get the turbo road worthy. Stay tuned...

[patina]

Kenik - you are making progress! When you talk about registering boost - are you using an analog boost gauge or the crap factory gauge on the tach?

[patina]

Also this may be a stupid question but did you check the torque on bolts on the cold side before the turbo was installed?

[kenikh]

Crap factory, but even the factory gauge doesn't register a zero at 5000 RPM. But I will check the data logs, too. Butt dyno confirms the boost leak, as well.

Congrats Kenik..........."Crap factory, but..... butt dyno"...sounds like you're putting the anal in analog.

[kenikh]

Anal log. Sounds like constipation.

[al lkosmal]

That should not be a problem.....once the boost is working well...........
Have fun on the trip.

So how was the trip (ASSuming problems were sorted in time, buttofcourse) - any skid marks laid down (on the seat)?!?!

[kenikh]

2600 miles later, I can report that the 930 stayed home. It was close, but no cigar.

[kenikh]

Boost leak problem solved. Minor setup issue with the solenoid was leaving the WG open, as I'd guessed. Haven't driven it yet, since the turbo is back out of the car to address the oil leak.

The good news is that the cause of the leak seems to have been identified. Just waiting for a new oil feed tube to arrive and we should be ready for another crack at it!

I'm going to start out road tuning, via the data logging. Once I think I have it perfect, we'll move onto the dyno for final tuning. The fewer pulls I have to pay for, the better. ��

Kenik,

Congrats on the progress - I'm sure the wait will be worth it.

[Ronnie's.930]

Too bad about the car not being ready for RS Kenik, but it looks like it's getting there! So a leaky oil supply tube (different than tube leaks that Paul is familiar with), eh?

[kenikh]

You know it is getting close when you start focusing on whack-ass details and BS.

First, what's not whack-ass is getting the big IC to fit right under the decklid. We took a stock IC up-pipe, cut it up and have mocked up a new up-pipe that will be welded in a configuration that will work. I'll get some pics on this ASAP, but it seems the intercooler conundrum is almost resolved!

Back to the whack-ass BS and there's nothing more whack-ass than electrical gremlins. These gremlins are so whack, I had to call in the services of a local auto electrical genius. So far, he's resolved the following previous non-op issues:

• The driver side window goes up and down
• The headlights work
• The turn signals work
• Four way flashers work
• Front and rear wipers work
• Dome lights work
• Brake lights work
• Cig lighter works
• Electric mirrors work

Is there anything that actually worked on this car when I bought it??? Some other nice surprises that will wait until I disassemble for paint:

• Wiring harness for fog lights is completely missing
• Headlight washer harness is missing, fluid lines are missing and the pump is dead
• Windshield washer fluid needs lines and a new pump

Other stuff that was more mundane, but is now done:

• Battery replaced
• Crankcase breather hose installed
• Oil sender was replaced
• Starter and engine solenoid replaced...who knew that the starter has a solenoid that kicks off cold/warm start fuelling???
• Turbo oil line replaced

So with a fully rebuilt engine and transmission, fully sorted electrical system and other mechanicals, this will officially be the ugliest, most mechanically sound 930 on the planet.

ETA for completion is now EOD Monday. Fingers crossed.

Nice, congrats on getting close man.

[kenikh]

^ Thanks! You've seen it more recently than I have!

[TurboKraft]

Finish line in sight!

[kenikh]

CAR IS READY! . Too late to go get it tonight, but tomorrow, we'll be in business!
