Talking Update on 968 Turbo Project

Posted an update of my 968 turbo project on YouTube. There are also a few other videos of other projects there as well. I'm hoping that public posts will help me to get the car finished in a timely fashion.

Love the time lapse.
I assume the 5 speed is from a 944 and the ratios work better on the track?

Were you able to retain ABS with going to the early offset in the rear?

Default ABS Question

Great catch! Yes. I used 1986 944 Turbo rear trailing arms. From the factory, the 1986 cars had aluminum trailing arms nearly identical to the 968. Porsche was doing some pre-planning and had the ABS sensor locations molded into the arms, but the locations had to be milled and tapped. The second difference is how the bearing is held in place. The 968 uses a 4 bolt plate and the earlier cars a “C” clip. In order for the early offset drive flanges to clear the trailing arm, only the “C” clip style works. The 4 bolt flanges interfer with the early offset drive flange. The ABS stub axles work with the early drive flange and the early offset aluminum trailing arms.

Thanks for doing that research and implementing the low offset “backdating”. What offset rims will you run out back?

Did you go low offset for the front?

i spoke with the owner of a race shop (we all like his race suspension parts that provide an “edge”. As I recall, his preference was for the late offset front setup, so I left the front late offset.

For wheels, I had a set of BBS wheels made (9” front, 10” rear) to match the late/early combination.

Very nice project! Look forward to seeing it up and running soon. What led you to the decision for the AEM Infinity? Just curious, as I'm still researching what standalone system to use.

at the time I purchased the Infinity,I had a tuner experienced in the AEM products lined up to handle the dyno sessions.

That sounds like a good reason to me The computer is one of my big concerns with adding the turbo, making sure I have a good baseline to fire up with and then getting it tuned right. I'm not very familiar with any of them, and could see that part being a major pain. On my last build I just installed new chips- nice and easy!

check out the AEM website. Their box is based upon volumetric efficiency, so any upgrades to the engine won’t require a re-tune.

Will do, that would be nice. Some of those setups look to be pretty advanced with self learning and features like TCS, launch control, etc..
