944T/968 how many years owned?
Discussion
Superb strong cars and just about the only weaknesses were cam belts (common to type), cam chains (944S, S2 and 68) and one to look out for - the head gasket.
The gasket rots away and when it does it allows the coolant to short circuit and miss out flowing back to the rear cylinders which overheat and will eventually seize wrecking the engine.
Oh and the gearbox pinion bearings can get noisy but easy to fix.
One of the best range of cars Porsche ever built.

Hi Blade, I bought it in 2007 & then never really used it - just dry stored it as the restoration of a listed house & various other projects took priority.
I had been collecting parts since 2007 & then sent the car to Gantspeed about 18 months ago & they started work on the project in November 2018. There have been stand-down periods as they've worked on other projects like a full restoration of the third 911 delivered new to the UK plus their usual 356 restorations etc.
I chose to avoid the 3 litre crank because the 2.5 crank is stiffer, stronger, smoother, doesn't introduce undesirable harmonics & keeps the engine more over-square & revvier! I also wanted to keep the factory crank as I want there to be a direct connection between this car as delivered from the factory new & its tuned state.
At 3 litres the 8-valve head becomes the bottle-neck, in which case you may as well go 16-valve with all the additional fabrication & expense that entails.
My brief was to keep this a tuned matching numbers car rather than go the full "Frankenstein" & use a turbo'ed 968 block & head.

I wouldn't say it's inferior, but increasing the throw so as to increase the stroke has some side-effects which
needn't be an issue if the engine is operated within its designed rpm range, is balanced & a harmonic dampener used.
There are obvious upsides to the increased capacity - but my priorities were not about maximum power & torque at all costs.

Hi Blade7 and Baz. Had my Turbo around 10 years, it was one of Hartechs customers cars that was an abandoned project.
1986, 968 block and pistons with 2.7 head. I've just put the second clutch in it during my ownership, it's cosmetically challenged in places but that adds to the charm.

james0 is that our 3 litre turbo we built and if so it would be great to know how you have got on with it since and how the performance was handled by the transmission etc.
If it is it already has modified pistons to create the right C/R for the boost pressure used.
It was the subject of a favourable road test at the time and listed as one of the reporters favourite test cars.

Given age of these cars have most owners replaced the sills or dry storage has prevented issues.
They have aged well - so has the 928 GTS - I remember many years ago Wheeler Dealers found a mint 944 Turbo possibly an S and bought it so well it was a steal with nothing to do on it.... but then transformed it into a track slag, I cringed even then.
I’m not a fan of the Lux model but the Turbo Turbo S and then the S2 make for a very nice ownership proposition.

Regarding extra power, mines currently a daily driver and the power feels about right, plenty of off boost torque make traffic less rubbish.
It really needs money directed elsewhere. .
Given the state of the roads a couple of grand spent on more supple suspension would improve road performance no end.

Dallying a what 30yo car miles must be big but it’s good to see owners actually using them and enjoying them for what they are not garage queens on the hope of speculative value increase. It really needs money directed elsewhere. .

Blade 7 - things move on as I get older (now semi retired @73) and every time I go into the workshop - there is the block waiting for me to put it all together for someone to enjoy.
New alloy liners (with top deck security), special pistons, rods, cylinder studs, sodium filled valves, 968 head ( to use the camshaft variator to reduce overlap on boost) etc, etc, designed for over 500 bhp will it ever run - probably not now.
I keep stupidly looking for a turbo with engine wrecked with a view to finishing it - but I know I never will now - too busy arguing with people on the Internet and helping develop staff to provide new developments (like our oversized M96/7 and eventually the 9A1 Gen 2 engines). Then there is the problem of petrol engines being banned from city centres to think on - just not enough time to do everything anymore and too little time left anyway.
Enjoy these great cars!

Relatively new 968 owner here(about 2 years) so didn’t get in at the bargain years like some.
Mainly used at weekends because I live 2 mins from work but not a garage queen. Soon found lots of things that needed doing to make it really tidy.
Wish it was a bit faster if I’m honest but love the car on the right road, it’s a lovely thing to get into and driving it occasionally makes it feel special.
