New start up and idle video with the X-Force exhaust setup. This is with the exhaust valve open.

New IACV installed and working perfectly. Rebuilding the steering rack atm.

[Q8y_drifter]

Sounds pretty good for a single exhaust/muffler setup. The Varex system lowers the noise levels nicely when the valve is closed.

Got a used IACV i'm gonna test out tomorrow. I cant run the engine much since the PS pump is pretty much dry right now. Hoping I can finish the rack and diff before the 18th.

Oooh how's it sound? I'm surprised you fit those pipes under under the front of the car like that. I had to get ovals just to clear.

[Q8y_drifter]

Exhaust system is done and wired up.

Dual 3" piping merge into a 3" y-pipe to a single 3" X-Force Varex muffler. Sounds pretty good.

Base map has been uploaded and seems to start and run okay. IACV died on me so I disconnected it and adjusted it manually for now to keep the engine from dying.

Also shaved the stock fuse box wiring with the help of my friend and completely removed the C101 connector. Stock BMW fuse box now only operates the ext/int lights, horn, audio system, wipers and dash gauges/warnings.

Top steering rack seal blew out on me yesterday and leaked all its fluid so I picked up a Z3 rack rebuild kit from Gates (p/n 348515) and will be rebuilding it this weekend along with my 188mm diff.

Looking forward to seeing it running!

Tranny is back in the car. all clutch and brake lines have been bled and so far so good. Car is currently at an exhaust shop to get the piping done. I'm gonna have to shorten the header outlets as they're so damn long and point down towards the ground for some reason (why is that?)

I had to polish out the Sikky trans yoke since it fit pretty tight in the T56 tail housing bushing. I'm not sure if that's because of the tight tolerances of the rebuilt trans or the yoke itself but it's no biggie and it fits nicely now.

Once the exhaust is done I'm gonna have my tuner upload a base map to drive around and break the engine in before tuning.

I've been out of the country the last couple of weeks so not much has been going on. I've since fixed the clutch leak issue (turned out to be a missing copper washer on the bleed line) and will be reinstalling the tranny tomorrow. I've also finished bending & flaring my rear brakes lines so that's out of the way.

That 188mm diff I picked up from the scrap yard for $100? Well that turned out to be a BMW Motorsport 4-clutch diff. I opened the LSD up and everything looks fairly clean still. I have new clutch discs and some Porsche 2.1mm dog plates on the way and will be rebuilding it shortly. Also placed an order for a Garagistic 2nd diff mount for more support. Once the diff is ready I'll swap it out along with the CATuned axles.

I second that ^
