1989 Porsche 911 Carrera Modifications and Maintenance Rennsport Kansas City

Had this little guy come into the shop this week for some work. We have been waiting a little while for this car, and it is finally back. I believe this one was originally sold at Art Bunker Porsche here in town back in 89, and finally is back in KC

Long story short, but we have a set of SSI heat exchangers and a RarelyL8/M&K muffler to install.

After a bit of work, the old system comes down and out.

A couple things need to be modified to make the SSI’s fit, one is this heat shield bracket. Off it comes.

And a bare motor.

We ran into this issue on the 930 project, and ran into it again. The stupid oil lines to the thermostat. The replacement lines that were sent with the exhaust uses a thinner rubber material than the old lines, and they kink, restricting oil flow. Sooooo, I ordered another replacement line that will work better. Maybe I should just start stocking these darn things. So, in the meantime, I decided to service the transmission with new fluid.

And bleed the brakes.

And pull the delaminated fuel gauge off to send out for repair.

This car just came from a dealer, and the turn signals were not canceling. We are also putting on a 930S steering wheel, so it all had to come apart anyway.

Apparently this car had a different wheel mounted on it, as the horn contact/signal cancel wheel was not present on the backside of the wheel. Guess I know why it wouldn’t cancel now, lol.

Can the horn contact/cancel wheel be changed out separate? Or is it part of the whole wheel?

The left turn signal (only) does not cancel on my 944. It will cancel when turning right. So I’ve just compensated by making all right turns.

    Yup, it is attached with 3 screws. Good adaptation to the left turn problem, lol!

Hey Doc,
Thank you so much for these postings I always find them fascinating! Just out of curiosity, what kind of brake bledder are you using?

    Hey Michael,

    I use a vacula brand system (this one came from Snap on, but I think sears sells a similar unit now in their catalog) that sucks the brake fluid through the system and into a container (the unit itself), rather than using a power bleeder which attaches to the brake fluid reservoir and pushes the fluid through the system and into a catch bottle. The suction system makes bleeding much quicker, cleaner, and easier in some cases such as stubborn clutch cylinders. I believe Motive has come out with a little more affordable unit now that sucks like mine does. I have seen quite a few motive power bleeder hoses (the units that push) explode due to age even when only pressurized to 10lbs, and the result is brake fluid all over your engine bay and paint, so I have stopped using those types of bleeders. The only downside of this system is that it runs off air, so you need an air compressor to use it.

    Hope this helps!
