i have recently spent over £800 under the bonnet of my 2.3 cd carlsson including new exhaust manifold, clutch kit and both cylinders, full service, cat bypass etc. the problem is i am now being told that my tcs wire that connects to the butterfly has been cut and the whole system bypassed very poorly as a result i am getting no where near the performance that i should be. although my tcs does kick most times and it does sometimes boost fully please please help how much more money do i need to spend

this is a difficult one
If your tcs is cutting in then it does not sound as if the whole system has been bypassed...
you really need to take it to a saab specialist who can sort this out
two which spring to mind are WMSS and the other is Bourne motors
neither of them are local but I know they know enough of saab tcs woes to put it right
It may not be that expensive to put right
it just takes some-one who knows what they are doing
there may be others but I do not have personal experience of them...

good luck

I know Howe Engineering and Two Stroke to Turbo have both done a LOT of work on early TCS units as well. Hopefully someone can get you sorted without you having to spend very silly money on new parts, from memory this works out around £1500+ if you need a new throttle body AND TCS/ABS master.

Perosnally, if I get my car sorted and the TCS decides to call it a day (sods law says it will given the amount of work I've had done lately
) then I'll investigate retro fitting a standard cable throttle on mine. AFAIK this can be done if you can find a non-TCS 2.3 to nick the APC, throttle body and ABS controller from. If someone has had this work done and can contribute something to clarify this, then it would be much appreciated by those of us with the old TCS systems!

Assuming that you fixed your TCS problems, a 220bhp Carlsson "red box" APC will definitely allow more boost than a non-TCS 200bhp 2.3T.

As I said in my earlier post, to retro fit a regular throttle you would need to change the APC but the fuel injection ECU would not be affected, it's doesn't take a data feed from the TCS system.

Basically; the choice is yours. I would say that as the car is currently driving acceptably then take your time to look out for anyone breaking 1992 2.3T's to get hold of the parts at reasonable cost. I know that WMSS have a couple of older 2.3T's ,I don't know whether they have TCS or not. Should you decide to keep the car standard and running with TCS, obviously the risk of running used TCS bits is that they may not last that long themselves.

Anyway, best of luck and I hope you get the car sorted to your satisfaction.
