2002 E46 M3 // Build Thread

Recommended Posts

Official start to my E46 M3 build thread! This is joining my garage along with my 2015 335i M Sport and my 2008 328i daily. Progress may be slow over the winter months, but progress is better than none at all! Car is completely bone stock minus a brake rotor upgrade and some Bilstein shocks. It also came with a mountain of maintenance receipts to sift through, but the most important are vanos and rod bearing replacements. Sadly didn't come with subframe reinforcement so that will likely be the first order of business come spring. It was inspected and in great shape, but we all know how important it is to do preventatively on these cars. Here's a quick spec list and a nice roller photo I got on the drive home!

Absolutely gorgeous car. One of the best colors, factory 19’s and from here it looks to be in great shape!

How are you enjoying it?

Coming from the turbo N55, it's so much different. Throttle response is WAY better than I imagined, induction noise is beautiful, exhaust is meh (not a huge fan of the tingy sound stock), steering is incredible and my favorite part of the car. Coming from electronic steering where it sometimes gets floaty and feels like you're not in control, this is a HUGE upgrade.

Overall I love it, and it'll likely replace my 335i come spring

Really wanted to salvage the original steering wheel since the leather is in decent shape. Tried my best to "refresh" the stitching with some felt fabric markers. Probably didn't match color exactly but I think it came out alright, here's a before/after

Edit: I did wipe off the excess dye from the leather with alcohol afterwards

First time ive seen an idea like that. Not bad!

Any planS to track it/stance it/drift it/install a CF airbox?

Appreciate it. I think just going OEM+/restoration for this car. I'd love to see it on CSL style wheels but @Rekpoint says Apex or nothin. CF airbox is definitely in this cars future, unsure if I can afford the CSL one but we'll see 😁

Another small update, small details matter though right? Noticed the rear badge was pretty sun faded/cracking on the M stripe section. Rather than replacing the entire badge, if you just apply a bit of heat (enough to make it warm to the touch but not compromise the badge adhesive) the M stripes can peel right off and be replaced. I got the replacement vinyl from here if anyone is curious. Badge looks brand new and cost $8 and 2 min of time!

Found my first moist surprise. Went to go disconnect the battery to start installing my headers, and my flashlight caught a little reflection. Turns out the passenger tail light lens was slightly detached, allowing water in:( Thank god it didn't rust through the metal and I was able to wire wheel, clean, naval jelly rust dissolve and rust converter it. Finally I tried adding some etching primer to try to match the factory finish best I could. Probably not perfect but helps me sleep at night.
