Some photos of the handy work over the past few days.

New hole cut in the firewall


Firewall side relocation plates. There is a plate on each side of the firewall 3mm thick stainless.


Booster installed (yet to be painted :) still mocking up) Brake lines are still to be done properly ran out of time today.


The brake swing bracket on the interior side which has been extended to handle the move.


E34 brake pedal push rod was re threaded with a tap and dye set today and installed. It fitted perfectly.



New z3 Steering rack which we found out was a 2.8 lock to lock ratio one! .. win. A date with the degreaser and a hose, it came out new :)


Installed


15mm Spacers installed into the rack. Will investigate maybe putting these at the bottom to lift the rack to reduce bump steer however this all depends weather it will clear the engine, wont know that till the engine goes in.




Thats all for today ... more friday going to plan.

Update:

Sorry for the lack of photos on this one .. Will click some off tomorrow, forgot to bring the memory card up in the camera.

So just to tidy up the last post, I had the pressure plate / clutch and flywheel and pressure plate bolts all balanced.
Not much was needed to be removed and suprisingly the Sach pressure plate housing was apparently a 9/10 balance .. which was nice to hear.

Ok so today was pretty epic.

The brake booster was removed and the new laser cut brake booster relocation plates worked perfectly. Thanks to Brendon for getting the measurement bang on and Ollie for sorting the CAD and laser cutting.
Thanks to westy, he fabbed up and welded an extension to the brake booster swing bracket from the brake push rod. Just need to get the e34 brake push rod into it.

All in all the Brake booster was moved around 60mm to allow the s50 plenium to fit.

Tomorrow the z3 2.8 3.0 ratio steering rack goes in and e36 6 cylinder power steering pump and steering pump reservior goes in and will run the new brake lines.


Later in the week the 5 series sump and oil pick-ups go onto the new engine and we will attempt to shoe horn it and the gear box into place to check for final clearance.


Thanks to Ray and co, Westy and Brendon for today.

Sorted out the clutch / pressure plate today ..


Went for Carbon / Kevlar instead of a metal composite to keep the drive train rattles down and will be a little nicer to drive in traffic. Perfect mix of hard core driving / track days and heavy street and ablility to drive in rush hour without glazing up the clutch.





I had a 3035 ft pound pressure spring mated to a new OE sachs housing. Is good for 450rwhp.



All assembled ...







Off to be balanced tomorrow :)

Its been 5 weeks in the making and fair bit of CAD work plus mock up from westy's e30/e46 flywheel / pressure plate setup (cheers tony).. I bring you the billet s50b32 single mass flywheel.

It weighs in at 6.23kgs and had the dual mass ring gear put onto it to match my starter setup.



Old s50 dual mass vs the new single mass :D (quite the difference)




Should rev like a bitch now...

DTM Shifter and s50 -> e30 loom adapter :)

Bought a new toy today. 37k's .. basically only run in :)

Dragged these pics up from an old post.

The s50b32 has had a bit of a hard life outside and unfortunily had water in cylinder 1 which has caused a bit of pitting. The crank also hand a bit of minor rust on it but nothing that a bit of machining wont fix.

Rust in Cylinder 1


s50 block (note 3.2ltr cylinder walls are pretty thin as standard in the ole iron block)


Head


Double Vanos and cams which is going to be blanked off and removed in favour of a locked adjustible timing gear system.


As it stands cylinder 1 is being bored to 18thou to check that the pitting doesnt extend over the 20 thou (.5mm) bore we are looking to do.

Standard pistons are 86.4mm we will take it to 86.9mm.

Next is s50b32 mock up and getting ready for the engine build.
After this we have the interior strip out and roll cage install.
