Very productive weekend.
New input shaft seal for the gearbox. Was super careful putting this one in, made sure it went in as square as possible and tapped it just barely below flush.
Didn't take many photos since I was really trying to get the car driveable for this week. Motor back in, cooling stack in.
I installed a new MAF sensor, O2 sensors, fuel pump. But I still had a rough idle. Eventually discovered it was the MAF connector itself. The female pins were quite loose which meant that with the airbox off and the intake tube moving around with the engine the contact was not good. I squeezed the pins tighter and fitted the airbox so everything was solid and the idle was perfect. A quick look at the fuel trims in INPA suggest they are perfect but I'll do a proper log later and see how things look.
Front end taking shape
Back on the ground, first time seeing the final ride height (will settle a bit) with the new bilstein B8s and eibach springs. Pretty much perfect for what I was looking for seeing as it will be my daily.
Cabin filter and new windshield cowl fitted. Unfortunately I'm still missing the front air duct that feeds the airbox. The one of the donor car was broken so I'll have to make a trip to the scrap yard to get one.
Interior assembled with a few nice new parts, I'm still repairing the driver seat so I have temporarily fitted the driver bucket seat from the M3.
Sorry Olaf, this ones getting a badge.
Car got a much needed wash and out for it's first quick test drive.
Absolutely stoked with this thing. It's very quick, corner to corner it's not really any slower than the M3. Not quite as much zing as the S54 up top but much smoother and torquier low down. Still a few details to finish it off:
- Driver seat
- AC re-gas
- Air intake scoop
- Exhaust hangers, the 325ti has unique hangers which I didn't pony up for resulting in the tail pipes not sitting quite centred
- It's too quiet. I like my cars quiet but at idle you wouldn't even know the thing is running. It has a fully stock 325ti exhaust, so I think I'm going to open up the small centre resonator and gut it and see what that sounds like.
- Z4 FCABs
- Alignment
- Tyres, the Chinese ones on it are not up to scratch for the B30 torque
- Custom plate I think, this one is a keeper I love it too much already.
