944 Turbo S Engine Rebuild Thread

[Eldavo]

Had a knock from the steering shaft as it had some play on it.

Justin Webb (www.944spares.com) has just started to get the original shafts refurbished with new UJs and properly staked fittings. A new one from Porsche is now £300+ and the D911 ones appear to have taken a nosedive in quality.

I was a willing guinea pig to try one and it arrived looking brand new!





A couple of heat shields to remove and then 4 bolts to drop the steering rack followed by a bit of faffing to get it all lined up and back on. Could’ve done with a helper to hold the steering wheel straight, it’s either bang on or a spline out - I’ll have to check when it’s back on its wheels and can just clock the steering wheel round one spline if it’s out:

Had an overheating issue as the fans weren’t coming on or if I wiggled the plug they were permanently on full power.

Ran through the Clark’s Garage tests and ordered a new fan switch.

Quick test before fitting (I chose the most appropriate setting on my meat thermometer):



Before fitting the sensor back into the radiator I plugged the sensor in and held a lighter under it to double-check it went through the slow then fast cycle as it heated up. I got it to turn on the slow cycle and it blew my lighter out so I’ll take that as a good sign, fitted everything back together and now just need to run it up to temperature before going for an MOT next week.

Lovely job on the door cards
Too nice for a track car

 

[Eldavo]

Well it needs using

Good work. Looking forward to hearing how you find throttle response with the new intercooler, which in my case improved it noticeably over the standard unit, with a far better breathing engine up top.

I'm sure there was a steering shaft recall a few years back..

I asked an OPC about that years ago, and they knew nothing about it.

Not suprised..Unless you get a real knowledgeable old school person (rare) they don't know alot about the old generations of cars now sadly,if they look up a chassis number they can see anything outstanding. I was using Leicester Porsche until a few years ago, all the old guys have left now, i use a local specialist run by ex Leicester Techs now feel safer when they have the car, the Porsche centre is now rammed full of Taycans.

Very true. All Porsche seem interested in now, is ramping up the price of 944 parts. Want turbo TPS, lube up and touch your toes.

Came to the realisation I’m a bit too big for the seats I’d bought so started to put the old ones back in. I put the wider passenger seat in the driver’s side for a bit more comfort but now with that and the different door card I can’t reach the handbrake so may have to fit the narrower seat when I get it down from the loft.



Had some pre-MOT work that needed doing, things like a steering arm and track rod end so just had everything on both sides replaced with new while they were in there. One of the ball joints was knocking too so I got the garage to swap in the spare arms I had and fit the Flo Flex poly bushes that were sat in the box with them too.

HUGE mistake - there’s a reason Flo Flex don’t make them anymore, they’ve started to disintegrate within a 100 miles of use. Going back to the garage today to fit some Powerflex ones and I’ll pick the car up at the end of the week:



Car’s driving great though, done an oil change and started to get up the rev and boost range. 6k and 18psi feeling great:

I picked up these RS-style doorpulls from SDG Industries too and they’re a neat little finishing touch to the door cards.

Focal 2-way speaker setup in the doors sounds really good too.

 

[MarkK]

Those door cards! droool!!!

I got all the remaining “underneath” bits done today - A/C compressor and belt on, power ateeeing pump and belt on and zip tied all the extra oil lines, etc out of the way too. Will need to run it before I lock the tensioners off though:

You do know that power steering belt is too wide don't you?
Should be a 9.5 x 950

That extra 0.5mm will make it noisy

 

[Eldavo]

No. It’s the correct belt. And even if it was slightly noisy I wouldn’t hear it over my awesome engine and exhaust
