I drove it!!!

Congrats, Daniel! :party:As one of my former car buddies stated years ago after a build completion and the first start, "That's as close to giving birth as a man can get." :driving:

Shane, It would have to be a C Section as we are not plumbed correctly for birthing. Yuk!

 

Daniel, Congrats on getting through a lot of those gremlins. Your story reminds me of why I have not or will ever tackle a build. I just don't have the patience and/or expertise to pull something as complex as you are doing off.

Thanks guys! It was definitely everything I hoped for and I haven’t even been able to mash the go pedal yet. The turbo spools quickly and sounds awesome. I’m glad I went with a vent to atmosphere BOV (I guess there is a little ricer in me). I passed the brake and light inspection today. The guys was super easy going and seemed to skip a few steps since I drove it there. Let’s hope the BAR is as smooth.

A friend of mine takes on much bigger projects than me and I made a similar comment to him as you did here. His reply was that all it takes is the stupidity to start and the percistence to finish. This project definitely turned out to be bigger than I had anticipated and had I really tried to plan in greater detail I probably would have talked myself out of it.

Ok, after driving the car some more here are my additional questions:

 

- How do you put gas in these cars? I spent probably 10min to get about 2gal in at the gas pump. I tried every angle I could, but just couldn't get the nozzle down far enough to push open the check valve. This meant I was only able to fill it at the rate that this valve leaked. Is this just due to the CA nozzle design or am I missing something?

- After multiple attempts I can't get the speedo to work consistently. I tried moving the sensor, but only got a few blips of speed. Is this know to be finicky or should I start looking for issues? I'll try adjusting it again. Can the sensor be too close?

Fuel filler:

I removed the alloy filler/cap assembly and took a Dremel to the three spot welds holding in the spring-loaded flap restrictor doo-hickey the best I could, then tapped it out with an old screwdriver. It was a really easy job, even for me. This made it MUCH easier to put fuel into the tank, though it's still not perfect - I typically insert the pump handle upside-down, and just hold it the whole time. It's not too tiring due to the small tank capacity.

 

Speedo:

Could be the brass "top hat" thing isn't seated in properly, maybe? That circlip is a right P.I.T.A. due to limited access. In any case, the problem is more likely to be on that end of the cable.

+1 for holding the nozzle upside down and go at a slow rate. I have found some stations have higher pressures than others. Try different stations and see which have the easiest to control pumps. If all else fails there is the 5 gallon gas jug approach.

I doubt you could find one now. But, in the old days we had No Lead and Leaded gas pumps side by side. People who wanted to put Leaded in a No Lead car bought a nozzle adapter that had the skinny neck to go through the flapper, topped by a bigger neck that fit a Leaded nozzle (slightly bigger diameter). This was just an adapter, no conical funnel. A bit of automotive nostalgia that might be useful again.

The upside down method worked at a different gas station. It seems the nozzle design is something I’ll have to pay attention to. The car is now about 99% ready. I had the alignment inspected and weighed. Nothing is far off, but I’ll probably make a few tweaks. The car weighed 1630 with me in it and a full tank of gas. That puts the car around 1430 which from what I can tell is about 100lb more than a normal CSR. My cast exhaust manifold, turbo, intercoooler, and girthy engine explain that. Hopefully it’s well compensated for with an extra 100hp too :).

The external ring of the fuel filler assembly is scalloped in one spot, intended to be located at the top as relief for the pump nozzle. I have heard of it being accidentally installed rotated at another angle. Probably not your issue, as you seem to have a keen eye for detail, but something that's easy to check.

We are cooking now! I got the O2 closed loop issue solved. Apparently GM (or ECM supplier) elected to have a dedicated “ground” for the O2 sensor that had a 1v positive voltage. My aftermarket harness had this at the common chassis ground.

 

i drove the car for about 50miles yesterday and I have the referee inspection tomorrow. The next step will be some tubing so I can really romp on it, but according to my log I hit 5psi boost at 5000rpm and it was already fast. 20psi and 7000rpm on the way :).

Plates in hand! I’ve done about 200miles now. I haven’t been able to open it up fully yet, but it is fast. I’ve only seen 5k rpm (briefly) and 5psi (of the 20 or so it will see). Looking forward to being broke in and tuned for WOT!

I now have the title so it's fully legit. I don't have a mounting bracket for the license plate, but I've passed plenty of cops with no ill effect. I think I'll just carry the plates with me and see how long it takes to get harassed. SoCal cops don't tend to mess with expensive looking cars.

 

I've been trying to convince myself I have the 3.38:1 diff. I thought I had nailed the rpm to speed ratio well enough to say it was actually 3.62, but after spinning the tires and counting driveshaft rotations I think it is indeed 3.38. This was relatively important to me because my engine doesn't rev to 9k so I need some taller gearing. Even with the 0.82 5th gear I feel like the engine is screaming on the highway. I can drive around everyone in 5th gear w/o issue. It's hard to control myself!

 

I'm fighting a few small oil leaks and I've found a few loose bolts, but overall it seems to run great. I need to take it to a dyno to get the WOT AFR calibrated, but that will have to wait for after break in.

 

The other thing I've found is that I get a lot of exhaust fumes into the cabin. I'm definitely going to need to add some type of extension to the exhaust to prevent this. Knowing that direct injection exhaust is relatively bad for you (much smaller particulate sizes than diesel) I would like to avoid breathing them all.

 

I'm also still fighting the speedometer. It just doesn't want to read over 60mph. I've moved the sensor all over the place and it either doesn't read or drops out at speed. I did make the well known modification to the wiring by grounding the sensor to the chassis near the sensor. Before this I was having issues with the speedo jumping with the turn signal and cutting each time I pushed the brakes. Those issues are solved.

 

I went to my first C&C in Palos Verdes last weekend. That was the most Porsches I've seen in one place outside a Porsche meet. I arrived late and parked away from the crowd, but it was fun.
