You probably are (very) well known with the 4A-GE, you may have heard from the 7A-GE or even heard from the 5A-GE. But a 4.5A-GE? Probably never!

To clarify some things: the 7A-GE is a 1.8 litre engine made by combining a 4A-GE head and a 7A-FE bottom. The 5A-GE is a 1.7 litre (1720cc) engine made by replacing the crank and conrods with a (HKS) stroker kit. Both engines increase the capacity compared to a normal 4A-GE but because of their longer stroke they are renowned to be slower in response…

The 4.5A-GE is a standard 4A-GE with oversized pistons (83mm instead of 81mm) bringing up the capacity to 1.7 litre (1675cc) and is just as responsive as the normal 4A-GE. RS YASU is renowned for doing this conversion and of course the engine in the picture above is their showcase!

And here is the monster that is powered by that engine:

Yum yum yum! Can’t wait to hear what that engine sounds like! 🙂
