I shouldn't bother with the manifold kit unless you plan to fit a new manifold gasket. Best to leave well alone unless you are prepared for a broken stud scenario.
You will need a set of studs for the hotside , 4 on the manifold flange and 3 on the d/p flange. They are the same in both locations but different T25/TD04. The correct pt no for the TD04 is 9141730. The nuts are generally serviceable 2/3 times but the nos. are 30520445 at the manifold end and 92152032 at the d/p end.
The lines are fitted with a mixture of plain copper gaskets and Belleville sealing washers ( washers with a rubber centre)
You may need;
Water line from head;
4161162* x 1 seal
92150435 x 1 gasket
8124158 x 2 gasket
Water line from pump;
11066422 x 3 gasket
4161162* x 1 seal
Oil line;
11066422 x 2 gasket
92150435 x 1 gasket
4161162* x 1 seal
Turbo to manifold gasket is 9113937 for the TD04
All are available from Saab, Your copper gaskets will be fine, perhaps clean up with a very fine emery. I change the Bellevilles cos they catch on the threaded part of the banjos. It is not a bad idea to have a stock of these cos there are loads on the fuel lines, They come in 2 sizes. I got mine from Bill for pennies

Car has been at Surrey Rolling Road, Farnborough.
328.9 HP ( 292.3 )
350 ft lb. (350 )
1.31 bar (1.27)
The turbo is spooling later and delivering more at the top end. Compared with my last stg 3 run the crossover point is at 4000rpm on power and 3000 on torque. The AFR is now sorted tailing off to 12 insread of 13.2 before. That is probably down to the tired oem injectors (and / or fuel pump ) that have now been replaced with Dekas. Maximum bar now comes in 700rpm later, at 3000rpm i only have 0.75 as opposed to 1.25 before. On the road I can't say I notice the drop off in spool. It is still a nice smooth progression from 2000rpm. It does sing from 3500 on.
I had hoped for better, but I have never seen any dyno data posted to support any claims of 350hp. When you think about it most folks run GG injectors and I dont think they can physically flow 350. Charlie, the owner of SRR is impressed with the results and thinks them good for a 28 hybrid. In his view it is a bigger turbo so whichever way you cut the cake you will lose on spool and gain on top end. He has dynoed loads of Nissan sx with Garrett 28 and they are all 220/230. I asked Jules to map for progressive delivery with no aggressive take off in order to preserve the box. He seems to have done that. The extra torque all comes in above 3500.
Now that the AFR is ok i will enjoy the car. It is a great drive. In the meantime I will look forward to dyno data from others with a 9000 stg 5 tune

Good stuff! Would be interesting to see the dyno plots if you have them.

Still noone come through with dyno data on a hybrid stg 5. Surely there must be folks running the original TT gp buy hybrid and folks with the Saabflight. There must be data out there somewhere.
In the meantime does anyone have dyno data on a T25 2.3. I am curious to compare it with a TD04, particularly actual, not subjective, data on spool.
