1970 BMW Gruppe 2 2002 (M20B29 Turbo) Build

[88SuperETABD]

So a lot has happened....so I’ll catch ya up. I moved to Austin, Texas. That was a drive....

Transferred within my company. Bought my first house in April, and moved in May. Been enjoying Austin so haven’t been working on the 02 much. But there’s been some progress. On with the pics :)



Had to prep the car for shipment...so needed the hood!

Ireland engineering fiberglass hood.




Dad helped me put the windshield in. Used weed whacker refill spool to put in seal. Made install a breeze.



I had him help make sure I cut these holes right...laid it out with tape...



Drilled holes where the pins went thru then traced the aerocatch systems.



Talk about nerve racking...trimming it out with the dremel.



And the fronts pinned!



Love the intercooler peeking :) looks a little more sleeper :)



Stock-ish?



Now the car is sealed it can go outside!



First natural shower in years lol.



Then a rainbow came!!!

This pedal box was a royal pain in the ass!
Putting it in after the fact the motor was in, stupid idea.



And it so sexy with its black gloss powdercoat.



Shows a good view of the clearances I’m dealing with....

And that’s pretty much where it left off in California....cuz I was driving my
Girlfriends civic to Austin shortly after this and left the 02 behind :(
But this will be its new home!


Dad prepped the 02 for transport...first
Time it’s been in the street for a long while.








And she’s off to Texas...have a lot more to catch up, but need to go to bed...


To be continued...

Love this build!

[88SuperETABD]

Looks an awesome project!'



Could you flare the end of the parking brake tube to fit?

I think that’s an option if my routing will allow it. I think I need to put a spacer there between the tube on the 2002 and the sleeve on the cable...

1970 BMW Gruppe 2 2002 (M20B29 Turbo) Build

Been working on my other project but rolled the BMW out and finally sat in my car for the first time! Let me catch you up...

So of course the shocks wouldn’t just install...


The angle was off so I had to get creative...


Then got these bad boys...




Welded em on! And stuck a bearing in!



And voila!

I didn’t like my welds on my first ever box so welded them for a second try. Better, not great.




Gonna put the expansion tank above the booster


Also not sure if you guys ever have to take this off. I ported this coolant return on the head out. Silly casting...but hey? Everything counts right!



After





Made vent lines and started some SS braided hoses



Rolled the car out of the garage the other day, and put a seat in temporarily for shipping the car. Got a windshield, waiting for my seals from Steve @ Blunttech.



Put some more screws in the fender flares. Starting to look like a car [emoji4] and got to sit in it for the first time. Was great!



Booty shot.



I rolled it back in after failing thinking a e30 parking brake cable would be the right length in an 02.





Also the dang sleeve portion doesn’t fit the 2002 parking brake tube...not sure what to do here. Anyone ever shortened a e3” parking brake cable???

Tips/suggestions welcomed.

Can't wait for the first start vid!!!

[wworm]

Coming along quite nicely! Can't wait for a vid of some pulls :) haha

Chugging away,

Finally hung the differential. Still not done I guess...



Grabbed this secondary ear. Figured this was less of a pain then switching to e36 diff and messing with the speed sensor...



Ghetto hung! It worked while I bounced around with different stuff.



Getting ready to chop the other 2002 diff mount off.



Cut...and time to make new ones :)



Used the brackets that came with the garagistic mount.



Got them both made, I traced these onto other metal I still need to cut out and weld in. But have to get the car way higher to weld or take the diff/subframe out of the way.



Welded them in. And was pleased to see it hanging proper and my axles straightened out.

Then admired the meaty booty.



Now that it’s hanging where it is supposed to. I test fit the driveshaft with no luck :(

Had it shortened and re-balanced.



Now it fits!!!



Tightened everything up and it spins nicely.





Now that that’s connected. Workin on the fuel supply so I can start it!



Some 6061 sheet. 1/8” thick.


Made a template of the trunk...and cut it out!



Almost nailed it. Had to do some touch up to make it come in and out easily without binding.



Fuel cell will be mounted in this location...just need to figure how I’m gonna secure the tank yet make it easy to remove if necessary.




View from the bottom!

Any ideas for fuel cell mounting are welcome. I’m thinking some aluminum tabs welded onto the floor and then have metal straps or something to lock it down in case of a flip over or bouncing around.

Next on the list:
-Secure tank
-run fuel lines
-run brake lines to rear

Are you gonna make the stock gas filler work?

Nope. Gonna shave it. Holidays, the 56 and snowboarding have kept me from progress on the 02. But here’s some updates.



Got some headlights...with hella’s.




Installed. They need some adjusting. I have a rebuild kit I believe.



Got a hard pipe to get the coolant flipped to the passenger side radiator inlet.



Found a guy that sketches toon like cars. Had him do a colored render of what my plan for the car is.



Got the turbo supply line and a adapter for the oil pressure sensor.





Made up the supply line.



Made a cardboard template to size a box I can fit with still clearing all brake master cylinder stuff and have a clear path to route the coolant too



Installed the supply line.







Had the car pushed out to get Xmas decorations out of rafters of garage. I really liked this pic. My car glowing from the garage light. With the 56 aired out next to it :)



Started with some brake lines from Adams Motorsport aka Andrew that used to work at Ireland engineering.

They fit great! Pre bent!



Fronts done. I gotta do the rears next.



Marked the downpipe and pulled it out to tie in the external wastegate. I’d like to make another down pipe down the road with a screamer pipe for fun :) but let’s get this thing running first haha.



Turbo manifold assembly off.



Put back the downpipe and realized something is gonna give me trouble.



Basically the downpipe tube was too long to allow the waste-gate to have enough room for a v-band.

So I had to cut it shorter and reweld. Really didn’t wanna cut up a 500$ manifold, but hey. Sh** happens.



Welded Back up.

Put it back on the car. But has to come off for oxygen sensor bungs and weld a v band on the other end of DP. Also got 5 ft of 3” 304SS. Gonna try to find a 3”
Mandrel locally. If not I’ll be doing pie cuts and getting more practice with the TIG :)

Will update sooner this time. I promise ;)

This is great project and very satisfying to watch. Keep it up.

awesome updates!! Keep cranking it out man!

[88SuperETABD]

I'm gonna give it a shot without ICV...can always add later.



Cleaned out the trunk and started measuring for the fuel cell.



Made a base for the bottom of the tank to sit on... will put another bar down center in between.



I'm gonna sink the tank down in the trunk so the bottom is even with spare tire well.



That's as far as I got cuz my friend came over with a slide hammer and we tweaked my nose to align the fender and so the grill could fit!




open wheel rat rod 02?



I need to get a headlight bucket and the front will be good enough for me to start driving. Nice paint is last.



Packed all that shit back away. I need to get everything installed on the projects so I can have more room. Stupid 4L80e is really in the way. Need to get that in the truck behind the 454.

this is how i welded mine if it helps

[sampayne]

Thanks. Saved me some money :)

I haven't really decided. I may try to run without. But want it to idle nice. If possible with the cam... If I do, I plan to weld a nipple to the charge pipe close to the elbow and do a hose from icv to intake...it's not gonna look as clean and I don't want to buy a ICV...

Hope to talk to someone who has run with and without icv and if it's worth having with megasquirt.

Not sure if its helpful, but I'm running my car with no icv. It isn't boosted or running ms, just a chip, but it honestly idles smoother than before. I have the idle screw set to around 700 rmp, and once it warms up it is very consistent.
