Yet another, BMW E-36 LSx conversion... by BRAAPZ

3 minute(s) of a 105 minute read

Not much of an update. Customer projects taking priority. Finished and shipped one of our custom L-6 cylinder heads, on its way to France, received another complete road race engine for a head freshen up with a new valve train, maybe a little valve unshrouding and 5 angle seat work that needs to ship back to the mid west by the end of the year, and my fathers Turbo Charged SBC 350 short block I need to assemble in the next couple of weeks!

As for the M3 LSx project, been doing some research and actual fitment of alternative brake options to free up more engine bay space, details of which I am not at liberty to give out at this time, suffice to say, results thus far are quite promising.  

This conversion will incorporate a few changes that will help improve space constraints within the engine bay as well as lower the cost of the typical LSx E36 conversions.  

Stay tuned, updates are still coming, but may take few more months for specifics to be released.

Built another custom LSx engine tool as well;

Teensy weensy update.
Drilled and tapped one hole in the 5.3L block for the F-body alternator mount.

After receiving this F-body alt mount, it became immediately clear the truck blocks were not manufactured for the car accy drives. 2 of the 4 F-body/Vette mounting bosses missing on the passenger side of the block.

A quick search revealed that most just drill and tap the one boss that GM graciously cast in the iron truck blocks and just delete the 4th bolt that GM completely ignored on the truck blocks.

After setting up mine, using a machinists transfer punch then drilling and tapping that boss for 10mm x 1.5 mm, that missing 4th bolt boss looks like it is good idea, but with three 10mm x 1.5mm bolts mounting the alternator already, Ron and I both agree that 4th bolt is probably more for the NVH requirements, making the entire engine and accy package as one mass vs 10-15 individual masses all ringing and vibrating at their own frequency. The Datsun Z car Alternator is mounted with far less attachment and works fine, as such I’m not going to lose any sleep over this.
