thats right, i found the OE pass. side plate at a yard and then ordered the euro/drivers one from BMW munich. 

H&B decals output

had my buddy Smeraglinolo (yes thats really his name) make these for me from the original templates, took a bit of work in prep on my end and he spent a great deal of time making them, however for now im holding off on installing.

pulling the block

time to get dirty. and we have a scored block

 

H&B wheels

were the original H&B 3-ps wheels of the era. i sold em to recoup expenses and i wasn’t a fan of the fitment. they are still avail today.

fuel tank coating.

kbs (tank) kit was used.

3 step process, could easily be one the most difficult phase of this build. though these tanks are NLA i didnt have many options.

rebuilding the output shafts

these things were toast.

Air Dam

oddly enough HB specialists (once H&B) still had an original in the RAW gel-coat e24 air dam. safe to say i picked it up.






tear down part 2

i knew the head gasket was blown at time of purchase, here are the photos of its removal and the carnage that ensued pushing me toward the direction i took for a full rebuild.

  • note the “hemi’d”out chambers
  • ringed head
  • heat shield on hood
  • all point to what used to be a boosted monster
