just noticed you listed a quaife lsd in your description cool-
Yes needs fitting though! Running a stock box atm, thing is even with an LSD 2nd is 'off limits', so not sure if it's even worth bothering.

While the structural rust has been sorted, externally the 9000 leaves a lot to be desired.

All part of the fun though having some little jobs to do!

Here's the bad bits that I plan to sort over the next couple of weeks:

New tail light cover/lense:




New front wings needed (to be replaced by fibreglass items as A: lighter and B: refurbed would only rust again






New rear left door - Easier to swap for a mint silver one than fanny around banging dents out:




This is where it gets a little complicated! Not sure how I'm going to sort this area but where there's a will there's a way!

Awesome build! I followed the previous thread as well.

In what gear are you able to go full power? Also has it ever been timed? I’m curious of the numbers as I’d imagine it takes careful application if the throttle to get it launched well.

If you ever record it I’d love to hear how it sounds! ??
Regarding timing, I've timed the speedo at 8.6 seconds from 100-200 km/h in this vid:

For reference, a Murcielago takes around 9 seconds, so naturally I had to make a comparison vid:

https://www.youtube.com/watch?v=a3rjoU7WeGM

And compared to the 9-5, that took 10.5 seconds for the same increment; the 9k really is in a different league!

7.9 - C6 Z06

Obviously need a VBox to verify.

Few teething issues:

- Seems to get through a lot of oil, it is leaking a little but not loads. Will keep topping it up but does anyone know what could be causing this? It's been bored/stroked from 2.3 to 2.4 litres so maybe that could make the engine more leaky? Could be a gasket perhaps?

- Revs have started pulsating from idle to 1300 rpm, up and down about 20 times then the revs hold at 2,500 rpm. The ECU must be up to something or could this be an air leak? Griffin Dai I'd be interested to hear if you've had similar issues and would like to know who mapped your 9k; was it Faero also?

Other than that, I took this out for a proper drive last night; it's utterly brutal, the acceleration is visceral and a real adrenaline hit, the induction roar from the custom Jenvey inlet manifold even more so. £40 of Vpower in 2 hours is why I'll be cycling to work for a bit!

Plan is to make it a proper sleeper. I've removed all stickers front, side and rear. Next sleeper mods will be the removal of the tow strap and then painting the calipers black and find some stock looking 17" wheels that'll fit over the big brakes. Any recommendations?

If it's using more than it's leaking then she's burning it. It's putting out twice it's designed BHP, it could be anything from bore wear to turbo seals.

Last time I did any reading on Faero's project thread was about 3 years ago when he was rebuilding the engine and box again. How many miles has it done since then and why did Faero decide to sell? More importantly whey did the previous owner decide to sell after quite a short time?
Great questions.

The rebuild was done 3,000 miles ago which is when the Wossners were put in.

Faero sold it because he had a more extreme trackday project on the go (iirc) and this 9k was suffering severe rust issues.

The previous owner (after Faero) sorted the structural rust issues but blew the Quaife'd gearbox. He wanted more of a daily driver so swapped my 9-5 plus half a bag for this.

Still got the Quaife'd gearbox but need to get the LSD out and fit it in this 4.05 one.

It's making a lot of power from not much displacement so needs lots of boost. Some of that boost will be blowing past the pistons, pressurising the bottom end. Check the PCV breathers. Other than that, turbo oil seals?
Ok thanks will get Wes to have a look at these things.

Turns out it's not that it's burning oil, it has a pretty major leak from what looks like the sump.

It has a baffled sump so hoping it's just the gasket that needs replacing. Otherwise it could be expensive replacing with a brand new baffled one.

Either way I won't be driving it until it's been sorted.

I'm hoping that because it has a baffled sump that it hasn't suffered any recent oil starvation - the baffles should ensure there's always oil around the pickup which is what matters right?

Yikes that’s quick! Is it as quiet as it sounds in the video?
No it's really loud due to sound deadening being removed, i need to try and find a decent sound recording device.

This is where it settles. Will get looking for a new sump ready to be baffled.

Found out what could be causing the dodgy idle; there appears to be a crack in the inlet manifold, so will get this welded up alongside the sump.

ooh need to be careful with air leaks ,after the maf/map sensor -lean running and possible det will kill it stone dead.
i,m surprised it was,nt missfiring,did it struggle to make boost?
It has misfired once quite badly.

Not driving it at all until I take it to my mechanic.

No it didn't struggle to make boost surprisingly.

I'm just glad I've found these issues so early on as I want to keep it long term.

Looking at getting a daily driver. Top of my list is a Skoda Octavia 1.6 diesel estate. Incredible economy and would be lovely not to rely on the Saab for daily duties.

Not sure if it'd be strong enough to tow the 9k to the Nurburgring though, for example.

yeah d/d is a good call -no biggie if you need to do little bits and bobs -easy to do £50 in juice in a day or two in the saab lol ...

when you drop your car off ,get your man to go over the car top to bottom-always good to find any little niggles while its up on a ramp(funds permitting), saves lots of time waiting for the AA at the side of the road imo (and beleive me i know lolll)-

ps when is my passenger ride biggrin
True that. As you're down south will have to get to Santa Pod once all this is sorted and you can have a spin. I reckon you'll have 2-3 seconds on this over the quarter, and a working gearbox at then end of the day!

I would go for the 2.0. The 1.6 is good around town but the 2.0 often delivers better fuel economy at speed and is a far nicer engine. Also in mixed driving I got less MPG than the 2.0 engine and think the stated figures are nonsense.

I think a normal daily driver makes a lot of sense when the Saab is so highly tuned.
Good call, some amazing deals out there on these.

This one with the posh L&K interior has done 100k miles; barely ran in for these and only £695:

Found a mint brake light lense to replace the current cracked one:





Picking up a mint rear left door on Saturday, feel like Mike Brewer, a proper wheeler dealer laugh

I like that! Right up my street smile Would standard wheels fit over the brakes? Also, I think you should remove the silly tow strap... You'll be annoying a lot of people with 'better' cars in the traffic light grand prix or slip road races!
Tow strap and stickers removed drink, next job is to spray callipers black.

Further adhering to its 'sleeper' credentials, the 9k has an Abbott Racing triangulated rear strut brace, subtly nested out of sight, which I guess helps with handling (it does handle like a go-kart).

Sorry fella just catching up on this. Yeah Faero did all the mapping on mine (stage 4/5/6 and a quick live mapping which gave it a little more sparkle) Brought the 60-100 down from 4.3 to 3.8s with 10% thinners in the mix smile Definitely worth giving him a shout when it’s all sorted and pay for a live map if he still does it. He spent hours & hours perfecting the gt30 map (he’s st hot at it) wink

You’ve found he fault now but mine always had an erratic idle after fitting the 630’s. Was fine with the GG’s. Mine was also a TCS car and that failed once, that was undrivable when it went, idled from around 600-2000rpm and had no drive between here.
I'm surprised you weren't running 875 injectors at that power level. What do 630s flow to?
