1st Real Project: E30 BMW 4.0 V8
Discussion
Right, long break over (during which, I finished my dissertation and David made a guitar, from scratch!) so bit of a minor update from sunday.
The prop clearance to the fuel tank was a nagging concern to both David and I, so we decided to rip it out and do a proper fuel system. So, tank and swirl pot ordered, and after some flow rate testing a Honda CBR1000 motorcycle pump was selected for the lift between the two.
In the car:
Also did some further welding on the exhaust system, no pics at the minute, to incorporate a centre silencer and huge repackable backbox across the width of the boot floor.
Next weekend should see the exhaust all finished off, and provided we can source an 044, fingers crossed it will run on the new fuel system.

Right, another weekend of work on the BMW, initially attempting to get the fuel system sorted.
044 Bosch Fuel pump sourced, bracket made and fitted to the car:
Then we realized that the fittings needed were not included, D'oh, so turned something up on the lathe:
However a lack of copper/doughty washers prevented us from making further progress, so we moved on to fitting the coolant pipes:
Not overly impressive, but its another job ticked off the list. With that done, the rest of our time was spent on getting the exhaust finished. The down pipes and Y piece were sorted ages ago:
But due to the lack of silencing, the rest of the system had to be given much more consideration. Eventually we decided upon using the current silencer as a centre box, with a much larger rear silencer mounted across the width of the boot floor:
Centre Box
Back Box
Full System
With all this exhaust work, both David and I feel like we are making serious progress in the TIG department:
The remaining work needed to finish the system was the mounting detail, so take some 10mm stainless and an oxy torch to get this:
A little bit of bending, cutting, filing and welding later and we have a hung exhaust, albeit with only one mount
Time was against us, so we didnt manage to get the rest done, but next weekend should finally see the exhaust and fuel system complete, so we can test to see how loud it is.
One final pic of roughly where the tail pipe exits the body, bear in mind its not supported so is seriously squint:
More next week.

Really admiring the work you are putting in to this. Its going to be a savage machine once its finished, and I for one can't wait to see it! Massive kudos :-D
Ta very much!Very small update, fuel system complete & exhaust all finished.
Had the car running for a while to get up to temperature and test noise level.
New exhaust is 85db, 1 meter @ 45 degrees, 3000 rpm! It's whisper quiet, but over 5k rpm it sounds like an angry god gargling :-)
Happy is an understatement.
Sorry about the recent lack of updates, but nothing has really been happening apart from us learning to map!
The tick over and low speed/load fuel and ignition portions are done, but we need somewhere (a runway, im thinking bruntingthorpe) to do the high speed/load stuff.
Additionally, I am getting married in ~ 1 month so money is tight, coupled with the fact that I have recently (<3months) started a new job involving a serious daily commute, means that things will be slow for the forseeable!
The project will continue, just not yet...

If you need any help with DIY mapping, head over to http://www.geekmapped.com
Ta very much, I shall have a read :-)Just a quick note to anyone waiting for more....
Progress is basically on hold, as I have not long got married, with all the stress that entails not to mention expense, but as it stands the car runs and moves under its own steam.
The suspension bushes all need replacing before further mapping, as they are dangerous, but idle is all good and the drive train seems strong. Cooling system does the job and holds temps at a steady 85C and the exhaust is whisper quiet (apart from when its rev'd hard and then it sounds amazing).
Fingers crossed some progress will happen over winter, but I shall update as and when.
Cheers.

Right ho,
Due to a change in circumstances the drivetrain package from the BMW is up for sale.
So, 1UZFE V8 mated to an R154 box using bespoke spacer plate, very light billet flywheel (~4kg) and concentric slave cylinder.
Would prefer to move it as a package, but may split depending on offers.
Also for sale, spare R154 with 7MGTE bell housing and Mk III supra rear diff (Torsen).
Open to offers on the lot. Cash on collection, so no fear that I am some sort of scam artist. Will not deliver due to size, weight etc etc etc.
Cheers!

"so I turned something up on the lathe" Christ looks better than many professional parts suppliers could come up with! I admire how casual you are about your obvious talent with metalwork.Then we realized that the fittings needed were not included, D'oh, so turned something up on the lathe:

k this is a real shame... Rapid progress > engagement > hiatus > marriage > project cancelled.Guess the new project management office had reigned in the chief engineer
Just read this from start to finish and gutted it won't see an end, you are a real credit to yourself as its very rare to see those practical skills combined with engineering - a formidable package as highlighted by the pasta cutting machine!
If you don't mind me asking, how you are so fortunate to have free access to such a well kitted out shop?
