Thanks  

Let's hope I don't have to sell one of my Kidneys to keep it on the road!

It's going in for an inspection on Thursday to work out what needs doing and for some general maintenance. Will see what the damage is then.I was planning on trying to get this to the 500bhp mark, but that might have to wait now.

I've got my eyes set on a Ducati 748 for this summer, so that might keep me occupied.... for a bit anyway

Quick update - car went into the garage this morning and its leaking at both water pumps (front slowly, rear significantly).

Getting a new timing belt kit fitted whilst it's in and the cam cover gaskets replaced as they were weeping fairly badly.

Looks like getting a bike will have to wait until next year  

At least the car will be solid when it comes back, as I wanted to get the timing gear done for peace of mind anyway. Probably best as ideally I want to get it out to Combe next month.

Anyone think of anything I should ask the mechanic to inspect / replace whilst the front of the car is apart?

So, getting the following done:

Water pump
Aux water pump
Coolant flush
Timing belt + tensioners
Cam cover gaskets
Sump re-sealed
New spider hose (old one is a cracked)

It actually took a while for them to get the car on their ramps as it was too low to get into their usual workshop, they had to wait for space to free up in their commercial unit





Whilst the cam covers were off last night I took them home to clean up and paint. It took 5 hours to turn them around as the shop needed them back today and I have work. I used VHT  (the brand) high temp primer, royal red and clear coat. Took 15 mins between coats, an hour to dry, then an hour in my "paint oven" at 100'c.

Pretty happy with how they turned out given that it was a rushed job.







I'll be using the same paint / process on the hispec calipers, so quite confident the finish will be to a high standard now I've seen what a rushed job turned out like  

Really miss driving this - been over a week now and getting boost withdrawal

Got the car back from the workshop on Tuesday and done a few long journeys in it. It boosts all the way up to 20psi now (compared to 17psi before), so guessing the new spider hose and inlet manifold gaskets might have solved a boost leak.

Decided I'd pull the engine bay apart tonight to have a bit of a tidy up and to check everything was as it should be. I've already decided to replace the expansion tank (again) as the new(ish) one was horribly stained by the muck that was in the old coolant. I've also found that the TBB is split, And one of the thin DV hoses were torn.

Whilst I wait for parts to arrive I'm going to give the engine bay a good clean. The red cam covers set it off a treat!





I'm beginning to think that I have no idea how fast the car actually is, as I'm still finding boost leaks

So got the new genuine oem throttle body boot and expansion tank fitted last night. The tbb lasted all of 30mins and several ~20psi pulls before it decided to let go of the throttle body completely. Being left stranded on Hanger Lane roundabout (for those who know it) is not fun!

I refitted it and watched as my brother revved it (probably building 10psi or so) - its scary how much it balloons at only half boost  

Whilst I wait for WOT Motorsport to get the 034 TBB's back in stock, I'm going to try a wider jubilee clamp and some hair spray - I think the only reason the old one might have been staying on was due to the tear in the boot relieving pressure.

In the meantime here are some bling bling pics  

I did this more for cosmetic reasons before anyone starts getting scientific

I'm pleased to report that 'extra hold' hair spray coupled with a new hose clamp and a thorough degreasing has kept the TBB firmly in place   (I've got an 034 TBB and MAF hose on order from WOT Motorsport atm).

When I started the car however it was running like a dog. Unplugging the MAF smoothed it out so cleaned the sensor and disconnected the battery for a bit and restarted - all good now.

Took it out for a spirited drive last night and no problems. Strangely though, whilst the car is pulling better than ever, I'm now only getting peak boost of 15 psi only (had 20 psi before replacing the torn TBB). Definitely doesn't feel like the car is being held back by anything though...

I've got it booked into MRC for a health check for the 26th so will have refrain from driving it too much until then.  

Does anyone here know what psi MRC 'safe map' their K04 conversions to?

I was getting the common EGT (bank 2) implausible signal error so decided to take it out and re-solder. Was fairly straight forward as I have no DP heatsheilds. Even managed to get the sensor out the manifold with a straight open ended 17mm spanner.

Got a bit of good advice from member s4saf which was to remove the gel only from around the soldered points (most of the guides say to remove all of it).

Took the old solder off (actually looked okay) and replaced it.



Replaced it all this morning and took it for a half hour drive and a few WOT pulls and no fault codes

Will just have to see how long it lasts before throwing another one

Went up to MRC today for a health check and found the following:

-big hole in the n/s intercooler
-fuel pump running all the time

So looks like I'll be fitting a FMIC sooner than I planned. I'm half tempted to go for this one

http://m.ebay.co.uk/itm/B5-S4-RS4...b6ad3910f5bfffbc416%257Ciid%253A3

It comes in at just under £400 (plus import charges) which doesn't seem so bad. The alternative is trying to find a decent 300zx core somewhere and sort the piping myself.

Also ordered a new genuine fuel pump relay (£24 from carparts4less).  

The front inner cv boots are torn so will need sorting as well. Audi have quoted £74 for some new boots, or £380 for the cv and boot kit.

Anyone recommend any alternative places to find a quality cv kit? Or is it best to stick with genuine Audi for these?

With it running all the time the fuel pump you noticed an increase in fuel consumption.? How did they diagnose this dude

I'm not sure what it's done to the fuel consumption as I'm almost certain it's been that way since I got it. MRC pointed it out to me, as it should turn off after a while, but didnt. Either the relay has seized on, or it's been bypassed somehow.

I tend to get about 25mpg on a sensible motorway cruise and about 16-20mpg around town. My previous car was an RX8 which did 8mpg around town though... So anything would seem good after that.

Weirdly, the car should be running rich with a boost leak as big as mine, but if anything it's running lean, which points to a possible dodgy MAF I guess.

I noticed with mine having the egt fault on bank 2 my fuel consumption went really bad, when I bought the car I managed 350 400 miles from a tank, and then I struggled to even get to 160, I recently replaced the board, think the fuel trim takes a few runs to adapt back to normal flow. My lambda had been contaminated due to running rich for what must of been months. Always showing no activity. Since running for hundred miles that's cleaned up, fuel is getting slightly better but still sub 200 miles on a tank, but this is all city driving . No faults on system now, maybe worth 20 quid to replaced that relay and see makes any difference, failing that new maf to be safe, as silently they fail and cause other parts to fail.

Luckily for me both my lambdas are reading properly. It weird though, you'd expect with a boost leak the size of the one I have that it would be throwing codes - which it isn't  

The only code I've been getting has been Cyl 4 short to ground, so I'm waiting on some replacement genuine ignition coils.

I'll replace the fuel pump relay and stick a FMIC on it and see how it drives. I'll be going for some 630cc Deka's when it's next into MRC as well, which will no doubt make the fuel consumption even worse.

The list of stuff that needs doing / i have planned is growing quicker than I can keep up with!
