upgrading 2.3 lpt

[jsmith]

i have seen those boost modifying add-ons for the full pressure turbo - but it specifies that lpt has to be converted to full pressure. is there an easy add-on that will give a performance boost for the 185 hp 2.3T? what's involved in converting to full pressure? i drove an '04 arc which has a 220 hp 2.3T - i'd be interested in getting up around that level of performance. it was plenty quick!

In my opinion start with suspension, brakes, tires...before you jump in to more torque/horsepower.

Simon and Murphwiz have some very informative posts on the subject.

does anyone know if the 2004 2.3T arc is basically the same car as the previous linear with maybe just a reprogrammed ECU? from the specs they seem very close save for the output of the engine. i wonder if it's just a reprogrammed ECU and if so can a 185 hp lpt be flashed at the dealership with the '04 program?

The 2004 Arc is a de-tuned B235R (Aero) It has the larger Mits. Turbo.

It is not possible for a dealer to change program only update it. Not wise either. If you are looking for more power a proper aftermarket ECM is the safest option.

Hey Nick,

I just got an 04 arc. If I get a stage 1 upgrade will I go beyond the aero setting(250) and spin it up to 274? If the arc is just a detuned version, engine displacement is the same, I would think this is the case. Same turbo like your said, if I understand you correctly. What about the warranty invalidation in the states?

Thanks

John

also the upgrades on your site are good for automatics right?

Hi,

I have a 9-5 2.3t -99 and i want more power...i think like this, Saab have more resorses to test theire product compare to tuningcomanys.
So i have done this to my Saab:
New turbo TD04HL-15T (aero)
2 oilhoses to turbo
2 waterhoses to turbo
1 Trionic aerobox (240hk)
(Used parts cost me $900)
But i dont think the car wil break down if you chance chip in it, maybe the clutch wont hold for more then 350 Nm on a standard 95, can change it to aeroclutch it will hold for more then >400Nm

Performance products should not void your warranty. That is one of the most pleasant suprises I have had owning a Saab. My Saab dealer service department actually sells and installs Speedparts upgrades. The verbage goes something like "custom installed components will not void warranty claims unless they are the specific cause of failure". I too have a modded autobox and the only engine problem I have had was a bad idler pulley, which was good-will warrantied 2 weeks after expiration of warranty. I drive my car HARD and it has held up very well despite my lead foot and addiction to lateral g forces.
