She's a bit rough round the edges and many shades of black but mechanically pretty spot on.
Post a pic of the best bit, the engine smile.

Ok, not a great pic but I'm not near the car at the moment, it's awaiting an update though

Actually that engine pic is a bit embarrassing. It needs a good tidy up. The engine has been together around ten years and has lots of redundant wiring and things have changed over the years.

Hopefully I'll have time to give it a refresh when I swap the turbo.

Remind me, standard 968 pistons?

Yes, standard 968 pistons, turbo conrods. The 16v pistons with the 8v head drop the compression ratio.
I'm going to measure the volumes but it should (if what I've read is correct give a CR of around 8.65-1. Swapping to a 1.4mm head gasket should drop it down to 8.45 ish. Assuming my measurements match what i dug up elsewhere.
When it was last on a rolling road it was iirc 258ish bhp on the original waste gate spring.
Since then I sorted the closed loop boost control and I've had the max boost limit turned up to to 1bar and target of .9bar for years. As you can see from the pics it's not been apart in ten years.
The current turbo k26/6 as you know is too small but on the road it's not at high boost for long enough to matter too much but I'm aware it's far from ideal. The k27/8 should be a better match.

Thanks for the info James, it's interesting that a 8v head will work with unmodified 968 pistons. Do you know the difference in combustion chamber volumes between a 2.7 8v head, and a 968 16v head?

From memory about 20 cc difference in the head. I had it written down somewhere...

Nice enough to look at but £36500? I'd want either totally original spec or significantly more powerful than original. That's neither.

It's petite and light.

Does it really need more than the 2.7 ?

I bet it drives utterly wonderfully. I don't think that's a particularly unreasonable price. A car that's been completely restored with new parts. The cost would be shocking. Much more than the asking price.

The 2.7 8v isn't much better than the 2.5 8v, except the 2.5 would be correct.

Although I vaguely remember the 2.5 in the 924s was detuned slightly from the one in the 944

It also looks like a plastic cap glued over the top of the probably cracked dash.

More cc in 8 or 16v head?

Mine - turbo cab and coupe




Coupe needs some love after being tuned to around 350BHP and being my daily driver for over 10 years,

Here is my cab on the thruxton skidpan last year

"More cc in 8 or 16v head?"

Blade7

The 8v head has more volume than the 16v head and the 16v pistons have more volume than the 8v pistons.

So the combo of 8v head and 16v piston produces the lowest cr.
