no you don't....hehe, ok ,
The third-generation appeared in 1989 and was in production until 1991. This engine has the silver cam covers with the words only written in red, hence the nickname "red top". Toyota increased the compression ratios from 9.4:1 to 10.3:1. To correct the air-speed problems of the earlier genrations of engine the heads inlet ports were redesigned to have smaller cross section inlet ports, and hence has been nickanmed as the "smallport head". This change in the intlet ports negated the need to have the need for the earlier twin runner manifold and was replaced with a single runner manifold. Additional engine modifications to extend life and the reliability included under piston cooling oil squirters, thicker connecting rods and other components. Also of note the pistons were changed to accept a 20mm fully floating gudgen pin unlike the 18mm pressed in pins of the earlier versions. All non-US market 4A-GEs continued to use a MAP sensor, while all of the US-market Toyota 4A-GE came with a MAF sensor. The only exception was the US-market 1990-91 Geo Prizm GSi, which was equipped with the MAP. This engine revision upped the power to 138 hp (103 kW) at 7200 rpm with a torque of 110 ft·lbf (149 N·m) at 4800 RPM..

Wow *-*
*claps*
you know your stuff. The Prizm is actually american version of the Trueno BZ-R '92, Only to be sold outside asia. Yes those are AE101's in 83-86 Hachi Roku's. Many do such things to make their cars get a little power and increament of power-to-weight ratio.
Most Opposing Threat to 86: Honda Civic.
