Thank you!!!...

It felt wrong not doing stainless lines now that I'm in this deep, so I bought the Bimmerworld kit and finished up the front brakes.

ATE pads, Zimmerman Rotors, and rebuilt calipers I got...

Hey all-

Does anyone know compression height spec for euro 9.7:1 b25 pistons, or how to identify them? I'm trying to discern if a set of replacement pistons overseas are 8.8 or 9.7:1 before...

I scrubbed the wheel wells with purple power and a tire brush so I could start suspension reassembly. Painted some brake lines, measured/ordered new hardware for most of the car, assembled front suspension...

The ultimate street 2.9 pistons were ~$1300. They've always sold 84.5mm mahle m20 pistons (11251714810) for around $900 which could be what you're thinking of.

Custom pistons through topendperformance...

Good intel- I suspect this 318 carpet was original as I had to cut around the HVAC box.

The last big project on the 318b27 are front seats. I've been staring at parts for...

As far as I know there are four types:

84-85 detached foam (might be 84-85 325e that got detached foam and 318i that got attached, unsure)
84-85 attached foam, fine threading (from...

The PO put cheap carpet atop the pretty decent factory charcoal carpet so instead of installing the spare gray carpet I have sitting on the shop floor I spent an entire afternoon with rapid remover, a...

Still doable, just expensive. If you think you're going to rebuild it eventually, start buying parts now. Most of the stuff that I put off purchasing has either gone NLA, or way up in price.

I spent a lot of time in iX land during my formative E30 years and I'm not sure I'd describe it as rewarding. RWD E30s are more enjoyable to drive, and far simpler to own/maintain.

Would...

Agreed- I think it'll be a great daily with the eta motor. It's a 3.91 small case open! Considered putting a 188mm 2.93 in it but need to start focusing on interior now that the mechanicals are pretty...

Had an eta 2-1 downpipe handy, so I ordered some 2" exhaust tubing so I could make a mid section to adapt to the nicer m10 Ansa catback that came with the car.

The '84 m10 cars had...

How has S54 maintenance been over the years? Anything you wish you would've done from the get go? Nice to finally get the booster sorted I bet!...

The cooling system for the M20 swap in 84 318 chassis was pretty straightforward.

The radiator support is different in m10 cars from what I can tell so the early rad didn't work with the...

Main relay would click when I hooked up the battery. Car cranked fine but I knew I'd have to fix this before it would run.

Turns out Pin 30 on the main relay was shorted to ground. Pulled...
