I bought a Hemi - Project Lit'lphant
Did you know Toyota built a hemi V8?

[Image: AEU86 AE86 - I bought a Hemi - Project Lit'lphant]

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

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 Wiki is a bit confusing - in one place it states the V engine was superseded by the UZ, yet in another it says it was superseded by the GZ 12 cylinder.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)

Engine coolant Water

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 Crying Crying


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... Big Grin

Nice find I didn't know this gem existed. Too bad Toyota stoped supporting the platform with spare parts.

Regarding Robert:
He's a great guy and his service is top notch. Iv'e bought serval things over the years about his company ant the service was always great. From books to rims he never disapointed me. Only one time he could not get my stuff as he could not ship shock absorbers via airmail so i had to get it trough JAA which seem didn't care about this issue.

Daily Beater: Civic EG5
Work in progress Car: AE86

Are you planning to fit it to a car once finished?
Curious to see the actual dimensions of this.

Looks awesome, I had no idea that Toyota made such an engine. Just like Bean, I would also like to know if the engine is going into a car when finished. Maybe drop it into an 86?

a LOT depends on dimensions..... but @ 130 kilos... a Corolla(E7, or E8 rwd) could be the recipient... along with an R154, and a 3.5 final drive...... but for now the project is building the engine - power goal: 300hp and 300#/ft.

Right now the goal is patience... as I write this(May 2019) the engine is on a boat somewhere in the Pacific... but I have been doing some planning....



I have a new phone (and Bixby app)... it translates Huh Respect! Thumbs up!

Dis-assembly will have to be done with care so I can salvage what I can salvage. With any luck intake gasket might be metal like 4AG... but I have no such fantasies about the head gaskets... but I do know that if I can get them off in one piece... I can likely get them made Exclamation

That's a very nice engine to own! I did know about it's existence, but I have never seen any IRL or any pictures of one without a Century wrapped around it. Thumbs up!

I have been using the Google translate app to translate using the camera or existing photos for over two years now and it's a bit quirky and doesn't translate a photo into a new photo. I never heard of the Bixby app. Is it Samsung only? And does it translate in place?

I believe it might be Samsung only... it doesn't always work... and sometimes I need to "finagle" the camera a bit to get all the text to translate. But, on the few pages I've done to this point, it works well enough, without it.... Facepalm

As to the engine... I've seen it swapped into a Corona(late70s/early 80s model), and in an early 70s Crown coupe... besides the hot rod pictures.


I've been scouring the web looking for what I can.... for example, here is an article -https://www.carthrottle.com/post/a7rlem9/ - about a guy looking for head gaskets... the engine is fitted in his Miata Huh Interesting photo in there... I adjusted the lighting some... open deck, and bolt-on paired lifter galley/assemblies??

My new Hemi.....

[Image: AEU86 AE86 - I bought a Hemi - Project Lit'lphant]

and it wasn't 10 minutes before I got bit..... Huh

[Image: AEU86 AE86 - I bought a Hemi - Project Lit'lphant]


There was one shipping tragedy... and one I feared all along.... they (R&L Shippers) shattered the distributor AngryAngryAngryAngryAngryAngry

[Image: AEU86 AE86 - I bought a Hemi - Project Lit'lphant]


The WHOLE reason I bought THIS 5V-EU was this one had a distributor!!! At least they didn't break the lower half of it - that is the oil pump drive!


And a bit more disappointment... the reported mass of the engine was incorrect..... Crying Crying Crying

While light for a V8, it isn't anywhere near the reported 130 kilos Facepalm
