We're adding lightness!

Besides those are over-rated.

ADDING lightness, thats a new one. What more could you add to lighten it? Good plan tho :-)
But looking great. Good luck.

I think Colin Chapman of Lotus came up with that phrase - so I can't take credit....
I'm just not that clever.

Hmm. But I think Chapman became involved in some legal battles after one of his 'light' designs suffered a serious (fatal?) failure. Don't add too much lightness.

Alan

Very nice, Brandon - well done! You'll be giddy to have it back clean and leak/worry free!

Mine's coming out (like Rawknees) this month for that same cam tower leak amongst others. Lift now makes a that muuuuuch easier 8-)

Good luck with the final stretch...

Hey Paul-
Yeah I'm excited - makes me especially excited for the Rennsport road trip in September. I thought mine was a cam tower leak but it was actually between a couple heads and cylinder barrels [EDIT - dumb me - leak WAS between cam tower and heads]. Wish I had a bigger garage and lift....kind of. I'm also kinda psyched to have a good excuse not to do it and have an expert do it quick and right....

Paul has his hands full (literally ) with regard to leakage sources - extreme, long-term orifice (all of them ) wear and tear has taken a toll on that bisch's systems!!!

The motor is getting very close. Just so impressed with how clean and new it looks - with these old parts! Well mostly old...some of the oil lines are new. Got the tins back - they look new - the metal was in great shape. Gotta love Arizona/Colorado cars - no rust. Got the injectors back and saw the flow graphs. All good now. Just need to do fuel lines, ignition and exhaust basically.

Here's a few pics - they SHOULD be right side up!









I don't know wtf is going on - I took these photos myself with the phone held vertically. No matter how these photos get taken the site is turning them sideways. sigh. Oh well.
EDIT - apparently I was supposed to take pics with the phone sideways. Next time. Sorry guys. Worst picture thread ever.

LOL.
No, I asked before. He is saving weight. (adding lightness). The biggest saving would be in the crankshaft tho.

If you're a Windows user, use the Windows Preview app (right click on pic and select Preview) to check the orientation of the pic . You can rotate the pic while in Preview mode and save it. If it's a Mac you're using, well I dunno.

OK tomorrow is the big day. Motor has been done for about a week and it's going back in tomorrow. I did a few things on the car while the motor was out for rebuild.

I gave the engine compartment a general cleaning - nothing like concours tho...

The engine pad is in very good shape overall but the top was a little ugly - so I installed a Pad Keeper. Looks nice IMO.

Oh and the deck lid struts. And the rubber hose that vents the tail lights.



I replaced the section of power steering line from the reservoir to a hard line (yes not applicable to 930's). I replaced the fuel filter and accumulator and a short fuel line that was looking...aged.



Also replaced the section of rubber hydraulic to the clutch slave cylinder.



Here she is ready to go back in.

So the motor went back in on Saturday. About 6 weeks start to finish. I had the car at home while the motor was being rebuilt. Got a few pics. They might even be right side up.

The install went as smooth as it could go. No leaks anywhere - fuel, power steering fluid, brake/clutch fluid...or oil.

Startup was a methodical process. Before totally buttoning it up we filled it with about 7 qts of oil, then we started cranking with the fuel pump relay removed so we could build oil pressure. Got 3 bar. As for gas - I had replaced the fuel filter and accumulator so there was a lot of the system to fill before it even got to the fuel distributor. Plugged the relay back in and the pump activated. Then we did quite a few mini starts..where he turned the key and as soon as it started to catch he'd turn it off. This got the fuel into all the injectors. Finally we did the the real first start and she fired right up with a small puff and settled into a nice (but slightly high) idle. Super smooth idle. We continued to add oil and let her warm up. After a bit took her for a spin around the block a few times. Sounded great. A little more buttoning up then I drove her home. AFRs are off by about 1.0 so I'm doing a little fine tuning on my BL WUR. It's been a few years so I've been re-learning.

A few pics:

Going onto the flat bed with 6 weeks of dust


No more gunky scavenge pump and a new oil line


A couple shots form underneath - lighting doesn't show how clean it is....




I didn't take a pic of the final install...I guess I will. But man it's cool to have such a clean leak free motor!

So I eliminated the air pump, had the injectors cleaned so they are spraying consistently now, new cap/rotor/wires/plugs, cleaned out the intercooler with lacquer thinner, and considering the intake manifold bolts were not tight, all in all it adds up to a motor that is running so smooth. A little more responsive on the bottom end. Hard to tell much when boost hits..although I have not driven it a ton yet (been busy..and it snowed) and when I have I have not been going all WOT yet. Soon.

Can't wait for the Rennsport road trip.

So I did a little WUR tuning last night. I have the airbox removed while I do this - with a cone filter on the FD and filters on a couple breather. Allows much easier access to the WUR - and I realized that even with the intercooler and AC compressor in place I can remove the WUR! Last time I removed the IC every time - huge hassle. I can sneak it out the side. I do have a longer vacuum line already attached which makes a big difference - in fact it's probably a necessity. I'm at 15.1 cruise so just need to back off the warm CCP a smidge. Then I'll dial in the others. They aren't far off....

Here's a pic of the cone filter. Minor mod (notched the base to fit around a fuel fitting) and squish to get it to fit. Can also see how the pad keeper cleans up the appearance compared to before



before



Enough room to sneak the WUR out without removing the IC!



Not much to see but here she is now

Hey John - thanks. Sent them to a local place called Fuel Injector Specialists. Very creative name - but if my engine guy likes them then I trust them. He really knows his stuff.

Hello

I love your 964 C2 Turbo (965) looks like mine.

I have a couple of question and concerns. I see you removed the air injectors and air pump why ? I believe that even thought it looks better with out them having them connected doesn't not effect the performance, In fact you may have issues tuning the fuel WUR to work correctly because the oxygen sensor control unit is looking and adjusting for what was the air injected in the exhaust system the control unit will think its still intact and make adjustments according and lean it out thinking your to rich, does that make since ? I could be wrong, unless you're planning on disconnecting the oxygen sensor and running in a open loop all the time. which is fine for tuning but not long term. I'm not sure but you may also have other issues with not having the oxygen sensor plugged in because it has many other functions as well. Here's some info I found

Oxygen sensor.
The oxygen sensor provides the oxygen sensor control unit with information about
combustion efficiency. The oxygen sensor signal is used to continuously vary the airfuel
mixture via the frequency valve. The heated zirconia (ZrO2 ) oxygen sensor, fully
warmed up, generates a 0.1 - 0.9 volts fluctuating current in response to oxygen
content in the exhaust gas. Fuel mixture is electronically regulated based on the
voltage output of the sensor. Oxygen sensor out put is unreliable when cold. The
heating element brings the sensor element to operating temperature under normal
circumstances within 90 seconds.

Open loop mode (up to approximately 90 seconds after first start of the day) is in
operation when the oxygen sensor has not reached normal operating temperature or
if the oxygen sensor system has failed. When operating in open loop mode, the
oxygen sensor control module supplies a preprogrammed duty cycle to the frequency
valve.
Closed loop mode (activated approximately 90 seconds after the first start of the
day) becomes the normal mode of operation once the oxygen sensor has reached a
temperature of 315C (600F) by being heated by exhaust gases and its own internal
heater. The oxygen sensor signal continually modulates the frequency valve to
provide the correct fuel / air ratio.
Acceleration enrichment
To ensure smooth acceleration even when the engine is cold, an acceleration
enrichment device operating according to the pulse-duty factor is installed. The
acceleration enrichment process requires the output of the oxygen sensor control unit
to be provided to the acceleration enrichment control unit. This control unit is installed
alongside the oxygen sensor control unit under the left front seat.
The enrichment feature is effective only when the engine oil temperature is less than
35 (95F). As soon as the oxygen sensor temperature switches from cold to hot, an
acceleration enrichment at a pulse-duty factor of 75% is available for 0.5 seconds
within 25 seconds. When the engine oil temperature exceeds 35 (95F) the
acceleration enrichment device is controlled for 2minutes after starting the engine to
a pulse-duty factor of 75% for 0.5 seconds when the 0 and 7 throttle switches are
open.
The acceleration enrichment process is dependent on a number of sensors and other
inputs and these are:
35 (95F) engine oil temperature sensor mounted in the breather housing of the
crankcase.
15 (59F) engine oil temperature sensor mounted in the right hand timing chain
cover for the Turbo and in the breather housing of the crankcase for the Turbo 3.6.
0 and 7 throttle switches located in the throttle switch body
66 or full load throttle switch also installed in the throttle body.

Here's more info

Temperature sensor: he signal from this sensor is used by the oxygen sensor control
unit to fine-tune the fuel mixture. This sensor is a positive temperature co-efficient
(PTC) sensor. This means the resistance increases with an increase in temperature.

You may want to post on Rennlist 964 turbo forum. Most People on Pelican (great guys by the way) have 930 / 911 turbo's almost the same but different in the Control units and systems.

I just want to see you have a flawless running 964 Turbo.
