Turbo Week, Day 2 - Finished!

-

Er... it's finished. The turbo is on, nothing seems to leak and it runs sweetly. First of all, I bolted up the turbo and connected the oil lines, turned the engine over on the starter for about 20 seconds, then checked oil was present in the turbo drain... and it wasn't. Oh dear. Then I remembered I'd changed the oil, so of course it was going to take a little while for the oil to find it's way there. Another 20 seconds on the starter, and the golden goodness was there.

Next step was to install the trunking, and to actually attempt to start it. I did consider getting out the video camera for this, to catch the moment of fiery explosion so my family would have at least some record of my final moments (and perhaps get £250 off Harry Hill), but couldn't be arsed. So I just switched it on and it started immediately, no drama whatsoever.

I let it idle for about 10 mins, smoke was pouring off the turbine casing by now but I was pretty sure it was just the solvent burning off. Considered getting the vid camera out again, just in case. Still couldn't be arsed. Once it had reached operating temp, I reset the idle and timing (I've set it to a conservative 8 degrees BTDC for now). The smoke had stopped at this point, and I was feeling pretty pleased with myself; I reckon I could get a job at Kwik-Fit with these l33t sk1llz.

The final step was to install the BBR ECU and connect the vacuum hose. This is a piggyback unit, and works in conjuction with the factory ECU (it takes over when boost is detected, hence the vacuum hose, and retards the timing and increases injector duty cycle). The ECUs live together under a panel in the passenger footwell (see below). Running the vacuum hose through the firewall was easy, there's a little ready made nipple in the large grommet just below the wiper motor - you just need to snip the end off. I then pushed the tube in through from the engine side, there's no access under the dash.

Final start, with everything connected then; ignition on, green light showing on the BBR ECU means it's alive; brmmm! That's where I've left it today, I still need to fix down the ECUs and sort out the rat's nest wiring, and check for any slow oil leaks.

The car has no MOT so of course I can't drive it... but if I did I would assume I'd be impressed by the psssh-wooosh, even though it doesn't spool until 3500rpm and max revs is 4000 for the first 600 miles. Yeah, I can see myself sticking to that!

Adding bluetooth to a Mini with Harman Kardon audio

-

My R53 Cooper S has the unexpected bonus of the Harman Kardon premium audio system.  While it has impressive power and sound quality (once you discover the hidden settings ), it's firmly stuck in the past with just CD and analogue radio.  You can't change the head unit as the speakers are all wired to the 10-channel amp that lives in the boot, so new cables would need to be run from the head unit to each speaker, which would be an almighty faff. I wanted to add bluetooth so I could play my cheesy '80s music from Spotify, so bought a Grom BT3  which is a small module that plugs into the CD-changer port on the rear of the standard-fit Boost head unit.  It allows you to stream music from your mobile, and make/receive calls via the supplied microphone.  You can also buy another module that plugs into the Grom to provide DAB radio, USB, or iPod wired connections, I didn't bother with any of those, I just wanted Bananarama, loud. There are 2 versions of the Grom...

BMW E39 diesel pump replacement

-
Image
I replaced the fuel pump in the tank of the 530D yesterday.  It was quite fiddly and I couldn't find any useful guide on the internet, so I thought I'd create a quick outline of the procedure: Symptoms of failure : poor starting/cutting out when the fuel level falls to around a quarter of a tank. Cost : £42 from GSF , plus 2x 9mm petrol hose clips (the originals are not reusable). Procedure :  remove the rear seat base by pulling up sharply on it's front edge (there are a pair of spring clips holding it in place).  Beneath are 2 access panels to the tank, the pump is under the right-hand side one (behind the driver on a UK right-hand drive car).  Remove the cover and disconnect the 2 hose connections and the electrical plug (removed by pushing the locking clip sideways).  Unscrew the locking ring by gently rotating it with a hammer and chisel. Now slowly remove the fuel sender unit, noting it's orientation and how it slots into the pump assembly below ...

MINI tailgate hinge replacement

-

I replaced the snapped tailgate hinge on t'old MINI today, and it wasn't too bad a job.  The design is a bit crap and they tend to seize, and then break and attempt to bonk you on the head with the tailgate.  Didn't like that. The hinge is held on by a single nut but you need to partially drop the headlining to reach it.  To do this you need to: remove the tailgate seal remove the rear seats remove the rear side panel trim on the affected side This is all covered by some helpful folks in this YouTube video.  After this, you need to remove the white C-pillar trim; it's held in by 4 plastic tabs (2 top, 2 bottom), which fit into metal clips in the body.  It needs a sharp tug but there is a fair risk of breaking the tabs, but I got away with it. Now you should be able to gently pull down the headlining, to release the clip in the centre: That should give just enough clearance to get a 13mm socket onto the nut securing the hinge.  There is...
