oil cooler

Hi, guys!
Just a small advise requested:
will this oil cooler fit my Viggen?
If not, what do you recommend-a complete kit would be great (braided hoses, sandwich adapter, s.o).

Thanks!

What are the specs on the sandwich adapter?

That would probably be the only thing that could possibly not work.

The car already has an oil cooler. If you are adding a new one what are you doing with the original? New one needs a thermostat. Remember too cold of oil can be just as bad. The stock one has proven adequate at controlling oil temps in my 500hp cars. Now back to back repeat runs on the dyno with limited airflow can drive it critical in a hurry. The stock cooling fan doesn't flow over the oil cooler much.

I couldn't tell from the photos you sent. Needs to use macro on the failed bearing parts and the pistons skirts. Need to see if it was detonation or something else that beat the bearings out.


Track days and some 150+ runs on mine along with lots of dyno tuning on mine with stock Oil cooler and mobil 5-30 7500 clean.

I've seen a Oil/dirt/etc caked oil cooler that prolly lent to the sludging of 96 900SET.

Can you really put a price on peace of mind?

O wait I can... Its called checking the lack of funds in my bank account...

I'll just make sure my oil cooler stays clean.

GS short-shift compare

Having installed on my Viggen and enjoying the GS short-shift, I am considering to use also the short-shift for 9-3SS.

Anyone here drive or have driven both 9-3 og & SS, with GS short-shifts, to give me a comparation in terms of stiffness/short travel/overall feel over these products?
Thanks!

P.S. I also have the uprated mounts/bushings that Nick sells for the 9-3SS short-shift, so if you have any other hints for this install, please feel free to oblige me

P.S.2 I have posted the same theme in the OG 9-3 Performance and the New 9-3 SS sections, for users that are more active there ...

T7 head porting!!!

Since my engine is off the car, I took some time to fock up with the T7 head...call it "mild porting job

Market around the admission and the exhaust gaskets on the head, then slowly worked the way with an electric grinder, using an Aluminum grinder, then a fine sand rotor, then more smoother sand paper rotor with polishing paste.
Still working and trying to make each piston admission/exhaust the same dimensions.
Then the valve seats and springs will be checked, the head will be rectified and snapped on the new B235 engine block!

Since it`s the first time I am doing this, please make any observation and give me whatever hints/advices you have. Not so many info on head porting on Saab forums, thou

Anyway, pics attached!

Make sure you don't get too smooth a surface, it would be a waste of time to try to achieve that. You are only supposed to remove edges and stuff like that, not make the surface all shiny. Flow is better with a "rough" surface (a bit like fine sandpaper or something like that)

TRANSMISSION status update: from Planning to Undergoing!!!

6 speeds upgrade

call me a stuborn! (I can confirm that the F40 gearbox with 6speeds from the 2.2 liters TiD fits in the place of the F25 gearbox! there are guys that did this retrofit in Sweden. Rickard is one of them, on a 9-3OG Conv.)

So I sourced an F40 correct bellhouse (to be delivered Wednesday)...

I also took the 9-3SS shifter and linkage (I will use Nick`s 9-3SS short-shift and upgraded mounts), an F40 Quaife LSD, a Sachs racing clutch kit (9-5 Pressure plate and 9-3SS friction plate, semi-organic), that will hold some 650 Nm.
What I need:
- a 9-5 flywheel (still considering the Abbott Racing billet one, instead a the Spec...);
- F35 (Viggen or 9-5) driveshafts and a 20mm shorter shaft (on the left side.. a Sweden company (FIXIT) is make it custom);
- some time to fabricate the chassis/body mount for the gearbox and to mount everything up...
- some live mappning on the rottotest at Maptun (in the summer)
Pics to come!

I am doing this upgrade for the long highway trips... the 6th is sooo long, just check the final outputs (courtesy of Nick T.)

do you have any links to some supporting/backing-up material for the idea that the flow is better with a rough surface?

Only thing that comes to mind is the "Four-stroke performance tuning" or in your case "Forced induction performance tuning" by A. Graham Bell. They are almost the same book, but both worth a read.

6 speeds gearbox project

Slowly advancing on the 6 speeds gearbox project:

Look what came to my door... An F40 6 speeds gearbox, from a 9-3SS 2.2 TiD from 2004!

Up until now, I already source and have most of the parts needed:
- 9-3SS uprated shifter and linkage;
- I will use also the 9-3SS short shifter from genuinesaab (thumbs up for Nick!) and the uprated shifter mounts (also from gs);
- 9-5 lightweight billet flywheel from Abbott Racing;
- Quaife LSD for F40 6 speeds (QDH9J).

All I need is a clutch kit (9-5 pressure plate & 9-3SS friction plate/clutch disc) to hold 550 Nm and I`m ready for the install!!!

Special thanks for the advises in this project, to:
- Rickard from saabturboclub of Sweden;
- Valentin from the same forum (they both did the F40 swap on T7 engines);
- Ronny O. from racestuff.se;
- Fredrik Åberg from [email protected];
- Nickolas Taliaferro from genuinesaab, who is really helpful with his technical inputs (and constructive criticism );
- mackan from ecuproject (because I have to re-map my ECU to match the 6 speeds).

Wicked!

An F40 box from a 2.2TiD bolts right up to a B235? Sweet.

advise needed!

I got to the part of choosing the clutch disc (friction plate).

The set-up is the following:
- flywheel is a lightened billet one;
- the pressure plate is a Sachs racing, capable of 650 Nm

Now I have to choose the clutch, not as brand, more as type.

The options are:
- full round disc (same as stock) or
- lamell/6 puch style.

Any of the ones above can be solid or with springs.

The input I got until now is that the solid lamell one would be the most driver-friendly, while those with springs are more friendly with the gearbox, but they are more like yo-yo when engaging...

Please enlight me, what should I choose, for the most comfortable ride (after all, it`s a daily driver, not a race car)!

Many many thanks!

Lucian

P.S. if anyone has a 9-3SS shifter assembly, with or without the cables, used and for sale, pm!

What does that 9-5 flywheel weigh? The stock 9-3 Flywheel weighs 15.4lbs Alu one is only 7.5lbs (7 > 3.4kilos)

You need a sprung hub disk and the gearbox will still sound horrible at idle in neutral wand when unloaded cruising.

The flywheel must be an F35 type (thus the 9-5 flywheel).
The stock 9-5 flywheel is 10.25kg (22.6lbs).
The one I have weights 32% lighter (some 6.97kg or 15.5 lbs) and has the starter ring gear machined as part of the flywheel.

The recommendations I got were for a solid clutch disk, not a sprung hub one, especially to avoid any yo-yo...
Why would the gearbox sound horrible at idle?

P.S.1: Found out some good material for reading:
http://www.uucmotorwerks.com/flywheel/gear_rattle.htm

P.S.2: I actually drove a 9-5 Saab with an F40 swap...there was zero rattle (with a stock 9-5 flywheel, not a dual mass 9-3SS flywheel, and a Stage 2+ Spec clutch kit with a semi-organic friction plate: six puch on a side/full round on the other, with springs). BTW, the Spec pressure plate broke in a race-course. Pics attached...
