I will.

I just need telling which bits to get.

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

That is as comprehensive a reply one could ever wish for!

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.

Just been talking to TT on the make up of their hybrid. It is a GT28 compressor wheel with a 60 trim. It is fitted to a new TD04 HL shaft which they tell me is beefier than the std TD04, then finished off with their uprated design of sleeve/thrust bearings. They fit a new wastegate valve/seat wth new bushing.The new wheel is 60mm diam as opposed to 58 on a T19. I dont know much about turbo design so I don't know which questions to ask but they were happy to answer any questions I did. Perhaps the next time I visit Albert 666 I will slope across to TT and have a proper chat. In the meantime does anyone have any comments.

Mine should be fitted in the next week or so.
No doubt I might mention something when it is.

I had earlier reported on results after fitting my hybrid. Although an improvement on stg 3 something was amiss. A few more sessions on the RR and a great deal of input from Jules it all seems now sorted. Many thanks to Mark (Mark411) for supplying dyno plots from his Saabflight setup so I knew where I ought to be heading. Problem was twofold.I had put constraints on Jules to map conservatively, perhaps too much so, and hardware. Jules subsequently sent me a map as he would have done it without interference from me, and the hardware issue was a surprising one , the T7.
I removed each of the plugs in turn from the T7 and went for a drive, then replaced it with a brand new one. A noticeable improvement, with my Maptun gauge mounted up recorded boost of 0.5/1.1/1.5 at 2000/2500/3000 which was close to Marks boost plot. Now put the old T7 back with its inserts and got the same. All i had done was to disturb the T7-odd
Time to go back on the RR. Results now are;
Max power 356.1 hp
Max torque 410 ft.lbs.at 4000 rpm
Max boost 1.45 bar at 3500rpm
The hope was to keep the low down performance of the stg 3 and add extra on top from the stg 5 so a comparison between my stg3 and stg 5 plots is interesting.
1.Power curve
This is smooth and progressive with no aberrations. The stg 5 & 3 curves touch at 3000rpm (175hp ) but below and above this there is a positive separation for the stg 5. At 2000 the stg 3 is 50hp and the stg 5 67 hp, a 34% increase.Beyond 3000 the stg 5 just carries on North whereas the stg 3 is starting to curve round. At 4000 the gap is 260 to 312 hp and goes on increasing.
2.Torque curve
The stg 5 is higher throughout the rev range but they nearly touch at 3000rpm. At 2000rpm the torque is up from 150 to 175 (17% increase). and then heads on up to 410 at 4000. Beyond 4000 the stg 5 holds a steady gap of around 70ft.lbs over stg 3.
3.Boost curve.
This is a little odd to understand. Boost is lower than stg 3 until the curves cross at 3200rpm. The stg 3 has boost of 0.25/0.75/1.23 at 2000/2500/3000 whereas the stg 5 is lagging at 0.2/0.53/1.05 before peaking at 1.45 and 3500rpm. It does not match what i was getting on the road observing the tacho/boost gauge. I dont see why the RR should not replicate the real road but Charlie, the operator, says it always lags by " a few hundred rpm" I suppose the real pont is I am seeing more power and torque at the bottom end, irrespective that it is a lower boost so the hybrid is achieving more with less boost. A testament to TT design.
Beyond 3500 the stg 5 remains at a consistently higher boost, around 0.2 higher, before tailing to 1.0 at 6000.
I have some final fettling to do but it does seem as though you can have your cake and eat it.The delivery is smooth and progressive and i think the monster toque is handleable but i had in mind 380ft lbs and no more, i will think a bit more on that aspect.This TT hybrid does seem to do the business.

Thanks for you detailed feedback. It's good to know, and gives me a kick up the backside to get on with mine.

We could have a hybrid badge on the boot/toolbox/fridge now.
Teach those Prii a thing or two. Yes, it really is a word.

"9-5 Hybrid", that'd mess with heads nicely.

Below are my stg 5 dyno plots. They show the comparison between my stg 3 and the stg 5. It is obvious which one is which. I was very happy with the road performance of the stg 3 so was hoping to hang on to that with the stg 5. I did not really expect I could. It has done better. Torque and power are actually increased at low revs then from 3000 rpm on the stg 5 takes off.
The boost is irrelevant, it is a means to an end. It is flow that is important and the hybrid can flow 356 hp at 1.1bar and 5500, which is a brilliant performance. Note that i have a full Aerodyte 3" d/p and a tubular manifold which my well have some bearing on the flow. The plots are very smooth. That will have something to do with Jules's mapping. Jules also did the stg 3 You can see the effect of maxing out on my pump and/or injectors with the stg 3 AFR but this has been rectified on the stg 5 after fitting a Walbro 255 and Dekas.
The Maptun stg 6 tune gives a max torque of 540nm using a GT30 compared to 556nm with the TT. OK, the Maptun goes on up to 400hp but this hybrid really delivers if you are looking for a tractable road car. An excellent piece of kit.
