Lit'lphant - Toyota's Hemi V8

Postby oldeskewltoy » Thu Mar 21, 2019 10:34 am

Did you know Toyota built a hemi V8?

Image

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

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 Wiki is a bit confusing - in one place it states the V engine was superseded by the UZ, yet in another it says it was superseded by the GZ 12 cylinder.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

2 valves per cylinder
16 valves in total
maximum power output: (JIS net) 164 PS (162 bhp) (121 kW) @ 4400 rpm

maximum torque(JIS net) 289 Nm (213 ft•lb) (29.5 kgm) at 3600 rpm
Specific torque(JIS net) 72.36 Nm/litre 0.87 ft•lb/cu3
Engine construction light alloy head & block (reported to be 130 kilos[286#s]) for comparison a 1UZ tips the scales closer to 355#s
compression ratio 8.6:1
Fuel system EFi
bmep (brake mean effective pressure) 909.3 kPa (131.9 psi)(with a BMEP of 131 theres some serious room for improvement)
Maximum RPM unknown… but hemi article alludes to a crank capable of 9000 rpm
crankshaft bearings 5
Engine coolant Water
Unitary capacity 499.25 cc
Aspiration Normal


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...

Image

Image


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


So, I began my search... and it began with Moto! 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

ImageImageImage


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

Image


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


A WHOLE lot more to come... :D

So, for those who only know me as "oldeskewltoy"... I'm 60 this year, and so my car life goes back to the mid 1970s.... so I've had my share of V8 powered muscle/pony cars: Shelby GT350-H, GT500, GTO Ram Air III, and my last one(1990-1994) was a 1970 Mach1 Mustang powered by a 428SCJ. A few of my friends from back then(70s) had cars like an L-88 Corvette, and a Hemi GTX. So, while I may be recognized here as a 4AGE specialist, my past has many V8 builds.

The problem with all the American V8s from that era are their mass, the 428SCJ and large spline Toploader transmission for my Mach 1 weighed in around 800#s!!! :o The 426 Hemi engine by itself weighed over 750#s!!


Fine for straight line performance... but trying to carve a back road with 800# iron block on the front axle is just a joke... (tires back then were also a joke)

The first time(15 years ago??) I saw a Toyota "V" hemi engine was on ebay... (note custom intake with "dual quads" ;) )

ImageImage


I then did some searching, and found a few hotrods out there with the Toyota "V" Hemi engine

Image


But there wasn't much information available other then it was the engine for the Century for nearly 30 years. As I dug deeper, I found the specs - posted above - and it was the engines mass(weight) that got me interested in it again, and then I asked Moto.....

Image



While the engines weight is very light for a V8, there are no mention of external dimensions... all I have to go on for now is photos, it does look small in the Black Hotrod.... and it "fits" in a Corona......

Image



more to come...... :D

Oh man! Been a long time since I saw one of those. I had a small collection of Toyota engines that I thought were cool a while back. I had one of those engines sitting in line with a bunch of other rare engines. Here are a few of the other engines I scooped up an 18RB(see if you can find that one), It was an 18R with twin 1bbl solex carbs. Along with that was a line up including a 3M from a 2000GT, 18RG E and U, 2TG, 3TGTEU, 4TGTEU( the 3 and 4 T engines were turbo and fuel injected with 2 spark plugs per cylinder). A little .8l opposed, air cooled 2 banger 'U' series engine I took out of a wrecked Sports 800 (I got to drive that car, I would give my MR2 for one for sure!). Couple of other rare engines as well. Had a collection of unobtainium parts from TRD as well, like a roller cam and rockers for a 20/22R and a head for an 18R block with 16 valves (never used it as no one had pistons for it), and a 4AGE head. The head was a reengineered casting with reshaped ports. Another piece that just sat on the shelf until I was pretty much forced to sell it all. Thanks for dredging up those images from the rusty files in my brain!

I actually thought you were going to bring up the 'T" engines with that lit'lphant thing.

Of course..... :roll: I've heard a rumor the the V was used in some of the Stadium trucks.... not sure how accurate that is


Not sure why/how you got a hold of so many unique Toyota lumps... I hope you got worthwhile cash for them.......

Its funny you should mention that.... while the combustion chambers are similar.... the rest of the head is significantly different

Image


The rocker layout is also similar... but the intake rockers are unique - wrapping around the rocker - top rockers in photo

Oh a quick side note... my new phone... translates Japanese :shock:

I came across the engines at an importer(now defunct)
'All Engine Distributing' in Fresno CA. They had so many cool JDM engines! I'd go in just to see what he had, and occasionally I'd take one or two home.

I got 12k for all the engines and parts I had. That was back in '06.
