Has anybody heard or been involved with a Turbo charged 2.3 S motor? I am toying with the idea of boosting (low or factory spec) a high compression 2.3 S motor. I have all the parts, I just keep going back and fourth about doing that or a twin turbo rear wheel drive 900? Just toying with the ideas. Still in the planing stages. I just think burning rice with a wheels up launch would be a Kodak moment. Let me know what you guys think.

lol, dude, the viggen has a 2.3 turbo... i hope you have money to spend, cause making a fwd non turbo saab into a rwd turbo saab, with enough power to run good and lift the wheels off the ground, that's gonna cost a bunch.

i know someone is sc a saab, not sure if it's a na or turbo, but they're putting a supercharger on it, haven't heard from them in a while, not sure of their progress though

your little signature says there are two types of saabs, what are they?

well if you want it to be turbo you need low compression - and a 2.3 n/a block has different pistons not tuned or built quite right for a turbo car. The likely hood of it even lasting long after one strong boost is very low..... It's best to just get a 2.3T motor and play around with that.

No I don't have money to burn, but I work on Saabs all day in a private shop(not a dealer). And the 2.3S motor is 10.5 to 1 instead of 9.2 or 9.5 to 1 in a Viggen or SE. I have done the measurements and it will work converting it to a rear transaxle configuration. I just need a small fun little project . Just get some input on what you fine fellows would like to see.



As far as two kinds....the kind that needs a head gasket or one that WILL need one. You can use this for any one of the common items that will fail.

I know about the 2.3 and it will take a moderate boost level. They go pretty good with out the boost. The older 2.3 is different than NG blocks on the bell housing end ,I believe? And it also has the same ratio as a 2.0 block.

I'd say go for the turbo conversion project. I've boosted N/A VW motors that are around 10:1 and it's a lot of fun - 6 or 7 lbs of boost from a small, quick spooling turbo and bam! Instant power all over the rev band.

What would you do for engine management though?

I would use the factory Trionic system a T-5 . And your result is kind of what I'm looking for.

How flexible is T5? If you slap it on an engine with different displacement, boost, compression, injector size, fuel pressure, etc than a "stock" T5 engine, what will it do? Does anyone know? Seems like aftermarket chips for T5 cars are pretty specific to the individual application (i.e. use this chip with mods X,Y,Z) which would lead me to think that it's not a very flexible system.

This might be a dumb question, but what management did the N/A 2.3 use anyways? If T5, is it the same T5 as on the boosted engines?

I dont know, but would the crank from the 2.3 engines work in my car? Would I need a diff crank sensor?

Thinking of stroking it.

Tweek I know it will fit and I believe the crank sensor is the same, I know the stroke is different so is bore. The 2.3 uses motronic and yes the computer has the ability to accept the changes (it is very smart you know,smarter system than anything else on the road) the only thing I mat have to play with are injector flow rates. As far as running LPT that is easy once it is installed ,just unplug the BPC unit. I just have to do it and find out I guess.
