I bought a Hemi - Project Lit'lphant

[oldeskewltoy]

Did you know Toyota built a hemi V8?



This is the "V" engine - https://en.wikipedia.org/wiki/Toyota_V_engine - not a whole lot of information....

The "V" engine designation began in the 1960s, and ended in the 1990s. It began as a 2.6 liter V8, and in its last iteration it was 4.0 liters. Wiki is a bit confusing - in one place it states the V engine was superseded by the UZ, yet in another it says it was superseded by the GZ 12 cylinder. The later would be correct. While the UZ engine line is the next V8 after the V, the UZ was used in different applications then the V was, the GZ replaced the V in the only car to use either - the Toyota Century.

Some more info "gleaned" from the internet... (notice some discrepancies in power between this, and Wiki)

In my searches for info on this engine, I had heard that an old Hemi book had a few pages on the V engine... after pestering a few of my friends who build V8s... I got this...






Now the BIG downside... Toyota no longer services this engine - all gaskets will need to be custom made


So, I began my search... and it began with Moto(Club4AG)! I had asked Moto a few months ago if he knew of any engine importers that might help me. He recommended a few. I tried them, and I also asked Robert @ EP importers - http://www.etsuryu.com . Robert was a great help and found a Toyota V engine for me! To make a long story short - Robert couldn't import the engine for me, so I passed the information (YJ auction) along to an engine importer that came recommended on Facebook. Once the engine gets here, I'll post the engine service with whom I bought my "new" 5V-EU from...

and here it is - scans came from the YJ auction




Robert did help me with 2 other significant purchases... 1 - an original starter for this engine, and 2 - a 5V-EU factory service manual!!




I expect the engine to arrive sometime late spring, or early summer.


A WHOLE lot more to come...
