Helloooo,It’s on about 80k I think?
It’s not used every year and some years it does very few even when it’s on the road,but it runs really well,been to Europe in it a few times over the years for track days and to Cornwall.It had a full examination when it was put together,and a “new” big valve head ,I need a new cone filter at some point looks a bit old now but that can wait till next year,the black one is coming out Friday and I’m looking forward to that

Love those wheels!!!!!!
. You should put the forged wheels on the blue car onto the black car.
I’ve got a set of forged wheels powder coated in black that would look amazing on the blue car!

Was the blue car a Turbo S originally, quick restoration then up in a fancy showroom for loads of money. Never raced or rally'd
Whilst the cat’s away! Talk about thread takeover
Back from holiday now, hopefully I will have some time to start working on the car. Still got a sore throat though following a nasty bug I picked up.
These pictures are from the week before I went away where I made some progress.
Close up of the corrosion on the cross member beneath the intercooler, and the patches of corrosion from friction between the coolant tank and the wheel arch.
On removing said corrosion, there were a couple of spots where I could poke a hole with a screwdriver... luckily the majority of the section was in good condition. I cut out the worst spots with a Dremel, if I had a welder and the skills I would have patched them, but it is hidden and shouldn't reduce the structural integrity.
Used a good zinc-based primer to prepare for the colour coat.
Then a coat of colour, and some clear coat on the wheel arch (didn't bother with any clear coat on the cross member).
Then I fitted the new heater hoses, and a new engine earth cable.

I spent more time cleaning the intercooler exterior, lots of banging on the floor to loosen debris stuck in the fins, followed by vacuuming. Then I soaked the fins with degreaser and used the garden hose (to avoid damaging the fins with high pressure from the pressure washer) to flush. Then after it had dried inside next to the radiator, more banging on the floor to loosen debris stuck in the fins. Finally refitted with new/cleaned hardware!
My new clutch master, and slave cylinders arrived, and I dug out my new power steering reservoir which was a steal at £15 from an ebay seller.
Vapour blasted cross member and air conditioning hoses picked up from my friend Matt at MB Engineering.
I then started a job I'd been putting off, cleaning the power steering rack. It cleaned up very well with plenty of brake cleaner to start, then some water based degreaser and the pressure washer. Unfortunately, the hard lines are heavily corroded but will see how I get on when it is re-fitted.
With the intercooler reinstalled, it was time to refit the badge panel.

More updates....
Back in January I purchased a full 944 Turbo service kit from Porsche Exeter, I totalled up the individual items from various sellers (cheapest prices) but it was still more than the full kit from Porsche! So easy choice. On closer inspection it came with Beru spark plugs made in France! I may have to try and get some Japanese NGK plugs to replace them again at some point (what I had previously fitted).
Back from the past, next job was to paint the exposed steel on the ends of the air conditioning hoses—very strange as one end is aluminium but the opposite end is steel. I painted the steel ends with some Eastwood Aluma Blast that I had left over from painting the torque tube bell housing.
The high-pressure line was trickier, as to remove it would have meant disconnecting all the brake lines from the master cylinder (which I didn't want to do). So instead, I treated the surface rust with some Bilt Hamber Deox-Gel. I left the fitting submerged in it for around 24 hours and it came out looking great (I'd previously removed the valve cores and saved them for later).
Then I had to set up a spray booth in the engine bay. I used the plastic masking sheet on a roll again to cover the whole car and then cut a hole through to pop the hose through.

Next the big job was upon me...
Nice warm and sunny day, so I began by fitting the new genuine engine mounts to the subframe.
Then slowly lifting the engine into the bay so I could squeeze the subframe underneath and attach the mounts to the engine. Even with this much access to the mounts the right-side engine mount is almost impossible to torque. I was able to torque one of the bolts with the torque wrench and then the other one I had to settle for good and tight with the spanner!
And then an engine in a car!
I then set about fitting the front suspension back together and attaching the steering rack.
Then fitting the restored heat shields in the right places (although somewhere along the line I lost the left side engine mount shield, new/old one on the way from ebay).
More progress...
Wiring loom fitted, need to replace the connector for the knock sensor as the wires are damaged right inside the boot. Most of the vacuum lines refitted. Clutch master cylinder fitted, super easy to fit the new one and clip it back to the clutch pedal. Completely cleaned the clutch fluid reservoir and fitted a new braided hose.
The mega PITA was arranging the heater hose and valve so it would fit in the small space behind the cylinder head. I finally got it arranged correctly after looking at some old photos and other pictures from the web. Lots of tweaking the position of wires and hoses to make sure they were in the correct position.
Then last weekend I spent some time cleaning up the radiator (it wasn't that old when I took the car off the road and certainly looks pretty new). The radiator support bracket was filthy and took plenty of brake cleaner followed by a scrub in soapy water to get it nice and clean.
And finally refitted to the car and locked into place (you can also see the next items to get fitted in the picture).
