The engine VIN code 5 or VIN code 6 is the 8th character of the VIN stamped on the engine or on plate at bottom of drivers-side windshield. Both were OE with platinum-electrode plugs. The ignition and distributor are different between the two engines because the cylinder heads are different. There is the belief that the DOHC distributor can only be ordered from a dealer since the cables are integral to the cap, however this is not true. A replacement model with integral wires is available in the aftermarket.

Applicable to build dates Nov 1989 to end of 1992 production:

Vin 5 indicates the (legendary) Toyota 4A-GE DOHC, 16-valve, MPFI engine. Cylinder head designed by Yamaha. Engine oil cooler mounted behind bumper, in front of A/C condenser. Under hood emissions label or RPO LWO printed on the option sticker identifies this also. Service Manual Supplement specific to the GSi is ST373-yySUPP, where "yy" is the numeric model year.

Vin 6 indicates the Toyota 4A-FE found in Prizm Base and LSi models.

What is the difference between 1991 geo prizm and a 1991 geo prizm gsi?

The main difference is the engine. While both versions use 1.6liter Toyota Engines, the GSI is a DOHC engine, a version of the 4-AGE engine used in the 1st generation MR2 and the top of the line Corollas, and JDM Sprinters of the 80's. known for high revs and being a blast to drive. I had an 87 mr2, got 35MPG and ran like a go cart!! The interesting thing is that this is the highest HP version of the 4-AGE that was ever released in America, at 130hp, MR2/Corolla versions were 116hp, (japanese 20valve version makes like 170ish?), and it is not in a toyota, it is in a GEO who would think? The Corolla and MR2 stopped using this engine in 89, but the GEO kept it going another 3 years. Cool car, I hear it is quick, especially with the 5spd, and I have been lokoing for one, but they are rare.
