[ QUOTE ] Alot of imported 4 bangers use twin overhead cam Hemi heads. [/ QUOTE ] The twin cammers were generally all Pent Roof, easily mistaken for Hemi, but not the same as an OHC Hemi would have required a much wider head configuration.
[ QUOTE ] toyota even has a hemi v8 too I think?? [/ QUOTE ] Yup, the little V8 has been around even longer than the four banger. In fact the T series four was derived from the V8 as used in the top spec Crown and the hand built Century Limo. Both thos models were for domestic consumption only although a few Centuries were exported for Diplomatic use. It started with a cast iron block and 2.5 litre capacity. Tose are naturally the oldest and also least desireable. By the early sixties it was all aluminium and the capacity had increed to 2.8 litres. The later engines were 3.0 or 3.5 litres with the 'big blocks' sporting electronic fuel injection in place of the compact and very slick looking four barrel Mikuni carbs. The engine ceased production in 1998 and they are still available if you know where to look.
[ QUOTE ] spose thatd be out of an older rwd corola? [/ QUOTE ] Yes. Fron the first KE10 model produced from 1966 to the KE30 series in the mid seventies.
[ QUOTE ] I guess its a cool low buck option for those on a shoestring budget. [/ QUOTE ] Very much so. There's still millions of them out there and running so Toyota continue to make parts for them. However, they don't usually require a lot of parts since they are pretty much indestructible.
[ QUOTE ] didn't the V8s come in heavy trucks like ambulances, I thought they where only on the other side of the ocean though [/ QUOTE ] No. Some ambulances were based on Cropwn models but these used the SOHC M series in line six cylinder engines. The trucks all used large capacity in line six cylnder pushrod engines or four & six cylinder Diesels.
[ QUOTE ] Not sure, but I've seen some rods back in oz withtoyota hemi's...they look pretty damn cool but are a little smaller. [/ QUOTE ] Yup, they'll fit under a stock '27 model T hood so using them in later models is a snap. Most of the engines used here were imported by Ian Leiffman or some other bloke who had an 'inside contact'. The good thing here, is that Toyota has a parts policy to support demand for whatever parts are required and will continue to manufacture parts long after a car has ceased production provided there's still demand. As a result, the bloke who was then parts manager at Toyota Aus, was not only a hot rodder but he was able to convince them to supply and stock parts for the little Hemis that were being used by rodders down-under. There's still plenty of that stuff on the shelf and probably a dozen or so engines available for sale around the country.
[ QUOTE ] not sure on that motor may be a 4age with a custom valve cover on it.[/i] GE as part of the engine desigation always indicates dual overhead camshaafts. The four banger pictured is a T series with stock rocker covers. [ QUOTE ] and there are places that can import any jap motor u want. [/ QUOTE ] I'd figure that should apply in the US as it does here in Oz. [ QUOTE ] ive gotten a few for my hondas i had. i was going to put in a toyota 6 cyl dohc hemi in my 50 chevy. [/ QUOTE ] The SOHC and DOHC fours and sixes are all Pentroof, the Hemis were all pushrod engines and only four or eight cylinder.
[ QUOTE ] here is a Toyota Hemi V8, a few of these motors were imported to Australia in the 80s they originally came out in Crowns and Limos. Sorry that is all I know [/ QUOTE ] I know that car very well. Originally built by my good buddy Ian Leifman and now owned by Mark Chadwick, who just happens to be a member of The Confederates Rod & Custom Club, with me. It is a T Tudor sedan, has the Toyota engine and trans with Jag suspension front and rear. Will blow the doors of most SBC powered rods, cruises at 120+km/h and returns around 25 to 30 miles per Aussie gallon.
[ QUOTE ] The Tundra (formerly known as the T100) has a V8, but I couldn't tell you if it's a hemi or not. [/ QUOTE ] yup, they have 1 coil per cyl also.
[ QUOTE ] The Tundra (formerly known as the T100) has a V8, but I couldn't tell you if it's a hemi or not. [/ QUOTE ] The early Tundra usues a four litre quad overhead cam, four valves per cylinder V8 with Pent Roof Combustion chambers. The later models are 4.7 litres capacity. These engines are based on the Lexus V8 and uses a cast iron block with aluminium cylinder heads as apposed to the passenger car's two piece die cast aluminium cylinder block. These engines are also used in the LandCriuser and Sequia models. I'm not 100% sure but I think they are also available in the US market 4Runner and the Smaller Lexus 4X4 wagon which we know in Australia as Prado, although to save weight these two vehicle may use the aluminium passenger vehicle block. The Lexus LX470 usues a more powerful version of the same engine but fitted with inteligent variable valve timing. The Lexus GS, SC and LS range started out with a four litre quad cammer which later received variable valve timing in it's second generation and was increased to 4.3 litres for generation 3. On these cars the bootlid badge denotes the engine capacity. These are great engines and also available cheaply as Japanese imports with much better availability because they are also used to power crown models in Japan. If you can find a latest model unit with the six speed auto, you'll have a rod that'll blow the doors of pretty much anything and do it as smoothly as any new car. Only problem with the quad cammmers is that whilst the block uses a narrow 60 degree bank angle, the heads are pretty fat and they require a lot of space. They fit under the hood of fat fender cars easlily although the electronics can be a tad daunting to the uninitiated. Here's one I prepared earlier in a '51 F series picemup truck. It is much smoother and goes much harder than it did with a 351 Cleveland..
But of course we are hot rodders and we do like the principal of "too much is just enough." SSo, we did some fabricating and machine work, picked up a few parts from GM and......... It now goes even harder!
[ QUOTE ] Yup, what Seymour said. The 2TC and 3TC motors are half of the V8 Toyota Hemi. [/ QUOTE ] Almost but not quite, the heads do not interchange. Although some internal parts are shared. [ QUOTE ] There is a short piece on them in the Tex Smith Hemi book. [/ QUOTE ] Thanx to a couple of smart arsed Aussies. [ QUOTE ] They were manufactured from '70-'82, only avalible in crown and limo's in the Asian market, and came in 3.4L(207 CI) and 3.8L(231 CI). Made around 200 HP, and weighed about 250 LBS. [/ QUOTE ] Commenced with sast iron block in early sixties and ceased production in the late 90s when replaced by the quad cam multi valve 5.0 litre V12 in the new century model. The cars were never sold outside of japan. The only complete cars to leave Japan were for diplomatic use by consulates and either returned to Japan or were sold locally as complete cars. It;s unlikely that any of these cars would have been wrecked for their engines etc as they'd be very low mileage and in pristine condition when sold. The Century is the only completely hand built Toyota and even today they are built in a separate plant completely by hand. Most components are unique and they are fitted with an unbelievable range of equipment including TV, bar and communications stuff. You can order your century in any colour you wish so long as it's black. However it'll be the best black paintjob you ever saw, being hand rubbed (colour sanded) between each of the eight colour coats. Whilst the current model carries contemporary features the styling still harks back to the mid fifties limo look and the car is unmistakeable in a crowd. They cost more than a Rolls Royce to own and only the very rich or very special have one of the eight cars built each week. The Emperor has a very special version custom built specially for him.
[ QUOTE ] [ QUOTE ] didn't the V8s come in heavy trucks like ambulances, I thought they where only on the other side of the ocean though [/ QUOTE ] Not in the trucks but in their large luxury barges, believe they're called Crowns. Carps posted a lot of info on those motors and their history few years back. the 2TC's if memory serves me share a lot of parts with the V8s. Someone should forward this to Carps who is always willing to share and enlighten us on the mini HEMIs. [/ QUOTE ] You should know that sooner or later I'll find it. Also got blasted big time for discusssing T products and using the T word on this forum, so it's interesting to read this discussion. All the stuff I previously wrote is still on my old IBM shitbox, so it may take me w while to transfer it, but I'm happy to do so if anybody is that interested in these things.
[ QUOTE ] [ QUOTE ] ...3.4L(207 CI) and 3.8L(231 CI). Made around 200 HP, and weighed about 250 LBS. -Jeff [/ QUOTE ] Wow. That's a pretty decent amount of power out of a motor that weighs practically nothing. Considering the obvious potential due to the heads its sporting, I'm kind of surprised I don't hear more about them. [/ QUOTE ] One of the best kept secrets at Toyota. The block was usued most successfuly as a basis for the leMans racing program with OHC heads and was also the basic design for the most successful Champcar engines in the US. [ QUOTE ] Is there a whole world of rodded Toyota V8 Hemi's in Japan, Australia, etc. that I'm completely unaware of? [/ QUOTE ] Mostly in Australia, thanks to a hanfull of people who knew the sectret. [ QUOTE ] That one in the pic has me thinking the answer is yes. What about aftermarket parts & whatever? [/ QUOTE ] See my previous comments.
[ QUOTE ] The bad part is, they're ultra-rare. [/ QUOTE ] Not if you know where to look. I can put my hands on about half a dozen of them pretty much instantly. [ QUOTE ] The only cars that got the Hemi V8s were the exported, big cars like armor-proofed sedans for diplomats, ambulances, and limousines. And as you can see, they're getting old, so they are tough to find and there is no aftermarket for them whatsoever. [/ QUOTE ] The only armour equipped car built by Toyota is the special Century made for the Emperor. The only reason they are hard to find is because you don't know where to look. The newest one you'll find will be around eight years old, which for a secondhand engine is quite fresh, specially when you consider a flathead as an alternative. In fact I'd even make the comparisson to a Flatty with Ardun heads, moreso than a Chrysler Hemi. Both are small capacity free revving and compact dimensionally. The only difference is that the flatty has some pretty spindly bottom end components wheras the tojo has four bolt mains (cross bolted on the later models with six bolts), forged crank, con rods & pistons, plus a really good factory balance job, high pressure oiling system and modern bearings etc. [ QUOTE ] There is really a good piece on them in Tex Smith's Hemi book. A nice two-page spread that tells a lot about em. [/ QUOTE ] Yeah, I know.
[ QUOTE ] OH MAN, I want one of those, with a 4-71 on top. Or maybe a smaller blower, [/ QUOTE ] A 671 is just perfect, and the engine will love the extra manifold pressure. [ QUOTE ] if that would be way out of proportion. Is the one in this black rod different from the one in the "A" that was pictured? The valve covers don't look the same. [/ QUOTE ] Nope, same year and model. The guy whho owns that T has or at least did have a few engines for sale. I have his contact details here somewhere, so I'll try and fish em out and post so anybody who's serious, can track him down. The inlet maniold on the T is fabricated.
[ QUOTE ] So again, just to clarify which cars had the hemi V8's in them (not 4-cyl's)... which ones? [/ QUOTE ] Domestic (Japan) market R series Crown Royal Saloons from 64 thru 68/9 and all century models from the late fifties to the model change in late '98. [ QUOTE ] And what are the differences in the V8's? It's obvious they are not the same. [/ QUOTE ] The first engines were 2.5 litres and featured a cast iron block. From gen 2 in the early sixties they were all aluminium. The last series during the late 90s has a die cast block as opposed to the earlier sand cst blocks. The capacity increased over time but the basic configuration and appearance of the engine remained unchanged other than whatever was required for updating to electronic ignition and fuel injection etc as this technology evolved. [ QUOTE ] Are there any guru's out there on this stuff? [/ QUOTE ] There are some who know a thing or two. [ QUOTE ] Maybe some older Japanese gentleman who happens to look just like the old man on the "Karate Kid".... [/ QUOTE ] I'm a little taller and have more hair.
[ QUOTE ] The new Tundras with the V8 have a Hemi look to them... [/ QUOTE ] Nope, they have a DOHC, multi valve look to them. They are also much bigger and heavier thanks to their cast iron cylinder block. However, they are very efficient and have an incredible specific power output. They won't fit easily under the hood of anything made before 1940.
Well dang, Carps, thanks for all that! As a thank-you, here's a few Crown's for sale in Aus, one cheap. http://www.drive.com.au/used-cars-for-sale/toyota/crown/pg1/@spg6/results.html This page has a guy in Canada with a '69 Crown engine for sale: http://www.oldclassiccar.co.uk/freeads/toyota_crown.htm Interestingly, this page says that most '88 Crown's had straight-6's. http://www.autospeed.com/cms/A_1986/article.html
While not exactly a traditional rod, I think one of those old Celica GTs that look like a mustang fastback would be a great home for one of the V8s. Or maybe one in an old HiLux pickup.
Man, you must have waaaaaay to much spare time to be lookin up those things. FWIW, the later model to current crowns are powered by straight six petro or 4 cyl Diesel engines as well as the qud cam V8s. The Crown and century are still built on a separate full perimiter chassis just like the cars we most adore. And of course they are big rear wheel drive vehicles too. The Japan only, Crown Majesta and Royal Saloons are better equipped then even the Lexus LS430.
