1970 BMW Gruppe 2 2002 (M20B29 Turbo) Build

awesome work! I had an early 2002 project. I got as far as disassembling an extra m10, then I sold it all. I don't regret it, though, the front cowl was demolished by rust, but the struts were clean.

wow!! dude, gonna be a fun 02.

So I finished up the cutting of the radiator support area for plenty of room for the intercooler,piping and thick z3m triple pass radiator. Should be plenty of room now :)

I want everything to look clean and kinda shave the bay. So I ground it to a corner. I will prob TIG that corner and grind it down. Newbie at body work. So all this is new to me

Frontal view. Plenty of room
Now :) going to make a radiator support bar that bolts to the flat panels there. Will prob weld a 1/8" plate or something as well to reinforce. Haven't thought this through 100% yet.



Also digging through boxes looking for parts. I found the original roundels for My car. They are aluminum, not plastic. Thought it was pretty sweet! Why isn't stuff made like it used to? I found the hood roundel as well. Just put the drill gun away and didn't wanna pull it out again to mount it. I drilled a slightly smaller hole and hammered the roundel in :). Next to my German plates I brought back that Mike gave me when I visited him.



I think I'm gonna polish them out for fun :)

Dude I didn't even know you had a build thread!! Coming along well man! You can definitely make Bimmerfest. Let me know when you need some more help.

[Kershaw]

That's an awesome project!

Looking good man!!

[Brad Sindoni]

Some progress has been made, got some new parts I had paid for a ways back, but holidays got my funds low.
Installed the Ground Control Adjustable Rear Coils. 450 lb spring rate



I need to change the studs on the rear hubs because they are too short for spacers to fill the flares. That castle nut was a big SOB. I tried a 20V Lithium Impact that did 350 ft lbs and a corded crafstman impact, and a 25" breaker bar with me bouncing on it. No luck. The trick is to invite your friend over and you and him both bounce on the end of the breaker bar holding your 45 lb dumbell weights lol. That is how much torque it takes.


In order to keep the hub from spinning I had to install one of the front wheels that had a tire on it + the parking brake.



I cant wait to get some rubber on the 15x10's :)



The passenger side drum was stuck on it so I started smacking it with the 3 lb sledge and the whole hub/drum slid off haha.



Driver side didn't come off the same way :(

Gotta get a puller for this guy.


Stud length difference



They press in from the back.



I wanted to continue with the front suspension, but I dont have an argon tank or helmet to weld with my TIG yet. So I put the subframe in the vette and went to a friends house to use his MIG to reinforce the subframe



Was a PITA to clean and degrease 46 years worth of oil leak + driving.

Used the IE subframe plate. That needed some massaging to fit. Nothing a 5 lb sledge cant fix.



I didnt feel it was necesarry to weld all the way across. Didn't wanna warp anything by putting that much heat into it.



But I stitched it pretty big all the way around.
Same with this piece. Figured this could warp easy.



Then I used some Self Etching primer, Some heavy duty rustoleum pro paint, and did some heavy coats



Leaving it to dry

In between coats I decided it was time to use the angle grinder some more to start cutting the radiator support out :)

First piece out



The more I cut, the easier it looked like the M20 was going to fit :)





After I made a ton of noise I decided it was getting too late to keep cutting. I'll continue this week.



Called it quits Here

so inspirational!! hoping to pick up a 02 soon!! looking forward to more updates, solid job so far.

Jealous of that welder. Im planning on getting a tig this spring. What coil overs are you using?

Do it! Welding is so fun! And resourceful! I will be making all my Christmas presents now haha. No more malls! Just the metal market.


I'm running IE sleeves, shorter bilstein sports, eibach springs, Ireland camber plates and offset spacers. Going to visit Ireland Engineering Thursday to pick up my stuff since I'm heading to SoCal for New Years.

So I continued to strip the struts down in prep to shorten and weld on a sleeve coil over kit.

Brake lines were so hard to get off. I had cut the rubber hose because I couldn't break them free in the fender well.



Then off came the caliper



Then I removed the hub cap with a flathead screwdriver and to my suprised the cotter pins were missing and the nut came off easy and the hub/rotor just slid right off!



Was great :)

To install the coil over sleeve kit you have to take off the original spring perch.



I grabbed the "trusty" $20 harbor freight grinder.

Started at the drain hole and ground through around the strut.
And Off it Came!



Then did the same to its evil twin!



Need to get a table saw and metal blade from my dad to make the cuts to the strut tube. 2" will be cut from the center of the strut. 3" from the top. and 12.75" from the bottom. So I cleaned up the garage since it was dark and getting cold.



Put a bunch of crap in the trunk :)

So excited to start using this machine :) I've been watching all kinds of youtube videos. I can't wait to get an Argon Tank and Helmet/Gloves and start welding!



I picked this welder because it was only 50 lbs, could run off 110v and 220v, could do any metal I pretty much will see. Can do much thinner than I'll need and can go pretty thick for automotive purposes. Can do 1/4" aluminum in one pass with some pre heat as well according to Miller. I hope to teach myself. I taught myself MIG, so any pointers, tips for teaching myself are appreciated, I plan to get a bunch of scrap and start doing beads with no filler, then I'll practice with filler once I feel ready. Then I'll tackle my subframe, then coil overs.
