looking back at the photos, I've had this car in the air for like 2 years. goddammit I need to hurry up.

E30 Picnic 2017 ?

I have the 328i brakes in hand already, which are 300x22. 330 are 325x25, which would be very tight in the weds.

I have the m14 left hand tap drill and tap for the locking bolt if you need.

You can also run 330i brakes but I'm not sure if they'll fit under 16s. They are 15mm larger rotors i believe. I have about 1-2cm clearance on my 16s running the standard e46 brakes

yeah, ebrakes are out already, went through all that with the black car.

not looking forward a ton to installing the fronts..

[pandaboo911]

In that case you'll have the exact same setup as I do. You'll probably have to shave the e46 carriers up front. Lmk if you got questions.

Ebrake lines are easy to remove/install fyi

Nice 5 lug [emoji6]

Running e30 m3 rear brakes?

yup, e30 M3 rears. got my hands on a set of caliper carriers and didn't see a need to figure out something bigger.


engine updates, got it torn down. here's some photos from the process.







an example of the scoring i'm dealing with:




In good news, I traded the S50 crank to Eric for his S52 crank and pistons, and arranged with Rebello to get the block boiled and bored out to 86.4mm, which should be happening in the next few weeks.

In the meantime, I am looking at bottom end bearings. Glyco's ok, yeah?

s52 pistons with an s50 crank will lead to very low compression

Booooooooost????

[ThatOneEuroE30]

sleeving cylinders is unfortunately not 60 a pop in the bay area

also I want new pistons anyway cause these are all pocked up

Well that sucks. Here I can get it done for 60 with labor or sometimes just for the cost of the sleeve. Whats a sleeve run out there?

[kronus]

why? Im not challenging you, just curious.

I would even be tempted to use a M52 crank if you could and make it a real overbore setup with a 86.4mm bore and 84mm stroke. Still would be considered a 3L (2955cc)

s52 pistons with an s50 crank will lead to very low compression, the wrist pin height is higher on s52 pistons due to longer crank throw.

I haven't looked at nonstandard builds yet.. not sure that there's a convenient piston that I can use with an 84mm stroke crank.

s52 pistons need s52 crank

s52 pistons need s52 crank

edit: wrist pin is higher on s52 pistons because longer crank throw

[2mAn]

Is your crank still good? Can you just go to the S52 piston size? It nets you ~3025cc and makes it a slightly overbore setup.

[kronus]

I got excited last night because I know someone who has a refreshed S52 block, but now I see you're looking for a S50 block... booo

yeah, I want to keep the s50 block cause bay area referees actually look at the numbers on it
