Q & A

What repairs and upgrades were done to the BMW engine?

The engine was fully rebuilt including new pistons, cams, cylinder heads, and rod bearings. It also has some upgrades like higher compression ratio pistons and higher flowing cylinder heads to make more power.

What was done to refurbish the brake system?

The brake calipers, rotors, pads, and lines were all replaced. The calipers were disassembled, cleaned, painted, and rebuilt with new seals and pistons.

What winter wheel and tire setup is used?

Square setup of original 18” Style 260M wheels with 245/40R18 Michelin Pilot Alpine 5 winter tires.

How is the engine broken in initially?

It's broken in by driving normally varying RPMs between 4,000-5,000 RPM for the first 1,000 km. Then the oil is changed and it continues to be driven.

What fixes are planned for the next steps?

Planned fixes include replacing the shocks, fuel pump, filter, headlight projectors, mirror, and tail lights.

What is the issue with the transmission oil pump?

The pump is working but there seems to be an issue with the car's computer not properly activating it, so it needs to be manually activated.

What is wrong with the clutch pedal feel?

The clutch pedal has too much dead travel at the top and bottom and feels light and springy. A new billet aluminium pedal assembly will be installed to improve feel.

What is the purpose of the engine oil changes?

Early oil changes check for metal debris to monitor engine break-in. Mineral oil is used at first to allow more wear then switched to synthetic.

How much power is stock and what is the goal?

Stock is 420hp. With upgrades the goal is to exceed that once fully broken in and tuned on the dyno.

What nostalgic memory does this car bring back?

Listening to music on the way to school as a teenager and dreaming of owning an E92 M3 one day.
