Another 944 Turbo Engine Rebuild Thread

Top mounts arrived after a short delay from D911, very pleased with them, they are quite thick and solid feeling. The bearing looks high quality and is held in by a snap-ring so can be replaced if required.





Gave the front struts a good clean with some Bilt Hamber Surfex HD and they came up looking very clean, I've got a new set of bump stops, socks , and spring hats / retainers for them as well.





Now just waiting on the H&R springs from CP4L (says they can take up to 28 days for delivery).

Quick update on this, CP4L cancelled the order after I called them for an ETA, they said they can't get any.

I've ordered another pair from a german supplier on ebay, will see if they have them in stock.
 
I believe its a heavy handed approach to the new online safety laws in that they might be hosting a picture of a boob and don’t want to have to get everyone age verified

I saw that, gives me a job rehosting all the images now! No warning either just gone, managed to download them all with the same file names over a VPN.

Apparently ICO as still going to fine them even though they've blocked access for prior violations of the UK acts :eek:
 
After waiting for ages for new lowering springs the H&R springs arrived from the German supplier in less than a week, and I also ordered a pair of Lesjofors springs from Autodoc which were listed as fitting the 944 Turbo (however it appears they were standard 944 springs for 2.5 NA cars, so returned for refund).

LESJOFORS






H&R




There was a slight issue with the new solid top mounts from D911, the supplied nut for securing the strut is not machined correctly so doesn't fully tighten down the strut assembly to secure the spring. After exploring a few ideas and asking for advice on rennlist I visited my friend Matt at MB Engineering and he converted the supplied nuts into spacer sleeves for me while I waited so I could use the original M14 nuts to secure the whole assembly together. I also treated myself to a brand new pair of spring cups from Porsche as the old ones were very rusty and crusty (don't ask how much, you will cry).

Is your rear re-indexed to match the new springs? Or have you got eccentric adjustment available?

Yes - I roughly measured the ride-height (using the factory method) and the rear was approximately 30mm lower than the front (that is with the eccentrics both adjusted in the middle of their travel). So that is why I went for the H&R springs as they quote a 30mm drop.

You could see the difference as there was a much larger gap between the tyre and wing on the front, and the rear was more tucked.

Going to re-measure the ride-height and have a go at adjusting the camber and toe on the weekend with a string setup that I put together after watching a few videos. I've got a digital angle finder for adjusting the camber, will post the method and how I get on!

Ideally after taking all the before measurements, you can work out how many turns the track rod ends need based on the thread pitch, which will hopefully get it near spot on without having to raise and lower the car too many times. Will also make sure to roll the car back and forth plenty to settle the suspension.
 
Fun and games! Good luck. My car was down 60mm at the back, obviously re-indexed before I was the owner. The GAZ set-up let me match the front. It was too low. By pretty much maxing the GAZ front ride height got me 30mm back up, by a sheer stroke of luck when I put on the Spax rears with helper springs on it lifted the back 30mm! It feels much nicer with the springs and torsion bar working in tandem at the back, less crashy and more progressive, completely lucked out though!
