<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Hi, <p>I made that modification too (adding the solenoid valve). Parts needed (saab numbers) were: <br> 4022224 slang <br> 7485576 Magnetventil (=solenoid valve, in english) <br> 7973522 Slangklamma 3st <br> 8978678 Konsol <br>No other mods should be done. Everything is ready for the valve in the car, so it's very easy job to do. <br>I think that there were some yearmodels in 9000's LPT-models, where this valve was already installed as standard equipment. <p>Another interesting question is the model of the turbocharger in 9000's. According Haynes manual, yearmodels 95-> are all equipped with TD04 charger. Was this the situation also with LPT-models, too? I thought previously that only T25 was used in FPT (200bhp) and LPT (170bhp) models. If you have further information on this, please let me know! <p>with best regards, <p>tom <p>Rob Bergin wrote: <blockquote TYPE=CITE>Does this work on a certain set of 9000?

AFAIK all 2.3 9000 turbos <br>are <br>> basically the same. What accounts for the difference in performance is the <br>ECU <br>> program and the APC solenoid valve. There are other subtle differences <br>(Aero has <br>> a larger turbocharger), but all these cars start from the same place. In <br>fact, <br>> one can consider the LPT a slightly detuned version of the CSE FPT. By <br>adding an <br>> APC valve and reprogramming the ECU (I have my own source for that) I have <br>> increased HP from 170 to 250+ with corresponding increase in torque. This <br>is <br>> only recommended for standard trans. It will work for auto, but the auto <br>trans <br>> will not last long. <br>> Regards, <br>> Richard <br>> <br>> Tommi Kalmari wrote: <br>> <br>> > Hi, <br>> > I asked earlier the exact differencies between saab9000CSE 2.3 LPT <br>> > (170bhp) and saab9000CSE 2.3T (200bhp) with poor results.
