It's an LSI if the engine is 1.6. The GSI should have a 1.8. I'm about 90% sure on that but not 100.

The GSi has a lot of different decals and the interior trim is different. It also offered a four speed automatic transmission.

What are the timing marks for a 1990 Geo Prizm?

Timing marks 1990 GEO Prizm GSI (4 AGE)The crank timing mark for the 1990 GEO Prizm GSI (4 AGE with twin overhead cam) is a notch found on the inside rim of the crank pulley. Set this notch to 0 for TDC on the Crank sprocket dust cover. The intake and exhaust cam sprockets have an indention on one tooth of the sprocket. Aline this dot with the crease in the back plate. The intake crease is a vertical crease at 12 oclock position and the exhaust is a vertical crease slightly before the 12 oclock position.If cam sprockets have been removed make sure you align the cam shafts before reinstalling sprockets. Set the knock pin of the intakse shaft to the 12 oclock position and the exhaust shaft to the 5 oclock position. Once this is done install the sprockets so their respective timing marks line up with the marks on the metal back plate.

What is the difference between a geo prizm gsi and a lsi and how do you identify which one you have?

The Prizm originally came in three trim levels Base, LSi and the short lived GSi. The LSi version came with more standard equipment than the bast model it also had colored bumpers instead of the black ones the base model offered. The GSi model was pure sport oriented it offered a beefed up suspension, four wheel disc brakes, alloy wheels, rear spoiler, red decal graphics, sport steering wheel, optional four speed automatic not available on the base model and the engine had a lot more grunt than the base model 130hp vs 102. The GSi model is very rare and was only produced from 1990-1992.
