FOSSIL FUELS - BP0 TURBO

put a spark plug in the exhaust that black (over fuel as you've just let off and im assuming you have a dump valve) will then turn into a massive flame and all dem girls be getting wet and shit..
 
Wideband shows a good 14.5:1 AFR though through most of the range. Could be oil seals I suppose. Piece of piss to rebuild anyway.
 
theres either a fault with the wideband or the map is terrible...

Should be nowhere near the 14's in boost :eek:

11's at best
 
That set-up has probably done 20,000 miles now in it's various guises. I really wouldn't worry. If there was a problem with the map, it would've reared it's head by now. I might just stop looking at this thread, it's beginning to get really gay.
 
Turbo rebuild under way ;)

Being off work for the last few weeks I've put my pictures in files on photobucket.

I'll go back through the thread and add some back in.

Well the turbo is now rebuilt thanks to Spook for all your help...

Before rebuild...

Rebuilt...

Ready to be refitted to the mera...

Might rotate the compressor housing slightly... It's a bit close to the manifold.
 
No need... Quickly checked all the exhaust housing... wastegate gap...all good

The manifold and and elbow are ceramic coated and the insides are very smooth impaired to standard.

Can't see getting much of a gain fitting a tubular manifold... May change elbow at some point but just want the car back on the road.

missing boost.. :(

just to let u know it had 3-4mm in and out play and 1mm sidewards play before rebuild...

Now as 0mm in and out and minuscule side to side (some movement should be there as it would be floating in oil ;) )

Again cheers for your help spook...

Have to take you and the Mrs out for.dinner soon.
 
We marked the shaft and wheel before disassembly. It went back on exactly as it came out so should be ok. In an ideal world with a few more poinds to spend you'd get it dynamically balanced but not on a kitchen table rebuild.
@Cov: There are loads of videos on the net about it. It's pretty simple once you get in there. Take the housings of both sides. Undo the bit on the compressor end whilst holding the ehaust end (reverse thread on these), tap shaft to pop it off the oil seals. You then have a circlip holding on a retaining plate. Once that's off you will see the thrust bearing held down by 3 screws, take these out and remove the thrust bearing. Under that is the first journal bearing, then circlip, then another circlip and another journal bearing. If you set the shaft up on the table and thread everything you take out in order into that its much easier to reassemble. You've also got 2 oil seals, one on the shaft (exhaust side) and one on the bit that slots into the thrust bearing. Assembly is reverse of removal.
I like to put one new bit on and then chuck the old one from the shaft into a tray. You know where you are then.
These are really simple bits of kit. Once you've done one you'll be able to do another one twice as quick.
