OMG, I need that DOHC head. Never thought I'd see one in use for real. Fantastic. FYI, I used to own Datsun Z # 427 which was produced in December 1969. Shipped to the states in Jan 1970. That one and # 17122 from 1971. Such great cars.
This is too all who have any questions about this car. This is Tomitaku's 240z, this is not a 240zg or a 432 fairlady z. This car still has the original L24 in it but has been heavily modified obviously. This motor originally came with a SOHC head but OS Giken of Japan produced 9 DOHC heads back in the 70s for the L24 for race application, hence the 24 in TC24-B1.. The engine also has triple Mikuni Solex carburetors which each has 2 44mm intakes. This 240z makes roughly 350hp.
@br1anzkilLs no its not the whole drive train, you dont need a different transmission or block or diff or anything like that its just a bored out block with a different head....
Its a OS Giken optional twin cam head for the L series engines. Worth approx $10K if still available. Z432 had a S20 engine and badges to identify it. Thats one sweet Z!
I don't think the Office Tomikaku looks for swapping or cheaper use. Rather perfectly matched, original cars that take your breath away with a simple stare, and make you re-live the best years of your life... Tuning a car is a work of skill. Restoring a jewel is a work of art. And it's obvious that you'll get more with an RB26 or a 2JZ, since they're turbocharged mills ! ;-)
right on man..........it's the nostalgia of it all in such a classic that you strive to hit. Nothing to do with $/performance what so ever at all. Nostalgia + bragging rights..........what else could you ask for.
@Euphorica And just think about it, this is the l24 the smallest of the 6cyl l series and it makes ~350hp. Thats mad nuts for these engines considering 300+ takes a serious proffesional to achieve in a L28 3.1 stroker.
What I meant was that putting a Skyline or Supra's engine doesn't seem to be their goal. From what I saw on their website, they keep a line of work, respecting a model's field. Good thing in my opinion. And this Z seems to be a "remix" version of the almighty 432(-R), that borrowed the PRINCE R380's S20 mill. To finish, I think OS Giken's purpose is : FUN. And for that, no (necessarily) need for performance. Just look at the drivers' faces and way of speaking once they get off the car !!! ;-)
Yeah, a friend of mine owns a BMW 325i 1997 mod with M3 suspension that he bought from a cousin, unfortunately he doesnt want to upgrade the engine, that thing would take out almost any car, but as it is now, he was even passed by a Golf ;)
RB26 or SR20 on 280z is insane, you feel the power up instantly even with stock engines, and the no-traction feeling even when driving a straight line at 40 mph is actually kick ass :)
Its sept 2018 why has nobody else produced a twin cam head for the l28. It sure would help save on engine swaps.....we have rapid prototyping now and 3D printing. You could easily adapt a four cylinder design . It could be a very affordable head.Why doesnt Giken produce them why only 9 .I heard they built another run , but surely it can be mass produced on a limited run to have more enthusiasts glorifing this great concept. I dont like engine swaps but a HEAD swap is a beautiful thing.
@PirateKing666 screw the S20, go OS giken. Picture a kameari 3.1L L28DTT with triple mikuni's. If your looking at build ability L28 any day. Until the late 80's the L28 was the most build able engine in japan since the early 70s. if your looking at nostalgia S20 is cool, but IMO i feel its more of a hakosuka motor and the sound of a stroker L28 is such god.
Exactly, should be able to get around 90`ish more hp out of that 2.5 litre. Today I saw a triple dellorto carburettor turbo setup for sale, it was listed for 240z 1970 model, so I`m not sure whether its for L28 (Although a big possibility, not sure.) Would be a cool thing to have for a one of a kind "RB30DE/NAT" as I call it, hehe.
i got the idea from my last project. highway spec built s13-sr20. that shit was taking out lambos, Ferraris, and even bikes, but then it got jack and now i left with the itch to built another highway monster. if times get better i am thinking the 280z with rb26, 240z with sr20, 89-91 mk3 supra with 2jz, or 2jz on my current e30. which ever project i pic will depend on my budget after i graduate from collage.
if is for the 1970 model it is probably for the l24 but i might be wrong because i don't know the engine year productions of the z's in Europe. if is a turbo system my guess is that it will be for the l28 since those where fuel injected and they also came turbo on the 280zx.
If you are running a stock drivetrain (Apart from LSD and tranny.) I should have been more specific and said you might encounter some problems with drivetrain (Mainly maintenance wise, parts getting worn out much faster, etc.) But there are those who modify drivetrain from say a GT-S or similar cars and fit them to Z`s, others are lucky and simply dont encounter these sort of problems for a long while, depending on their driving too. Owh, I`d fit a "home-made" RB30DE with triple webers :)
yes,but they are not using an L series engine they are using the OSgiken engine. it is an after market dohc made specifically for racing. my point is that the engine alone cost around 11k and for that kind of money i rather get rb or jz series engine. do u understand now. if they waned to keep it oem they would use the original engine like nissan did back in the day. and again the OsGiken motor cant not be used for competition.
Yeah basically a RB30DET block and RB25 head :) My economy is a bit weak at the time as well, so I decided to go for ae86 now, and get a 280zx later :)
i dont know what ur talking about because i know 2ppl that have rb's swaps and never had problems with their drive-train. 1 was running a stock 280z lsd with an rb25 n the other was running a 300 lsd n never had a problem either. the 300 pumpkin needed some customization. btw the 300tt transmission bolts to the rb25. so if u have an rb26 u can just find a 300 tranny instead of buying an expensive rb tranny.
i understand your point wen it comes to a restore project, but the OSgiken motor isn't an OEM part. if restoring to the original is the goal the building then the l24 is the way to go. if getting the most performance out of the factory motor is the goal then i would go with the l28 turbo. but if performance is name of the game then there is no doubt that the rb or jz is the way to go. btw you cant use the OSgiken motor in competition.
this is the nices sound i have ever heard out of a Z.Look at the car nice color and great sound,.If you have ever ovwend a 240,260Z then you know how it feels ,to drive a great Car.
lmao. a turbo-kit would be the best upgrade to his car. i would go with like a t3/4, full t4, or gt30r, @ .8bars. it will make it fast and keep it reliable. but i wouldn't boost more than that without extra work to the engine.
the OS Giken head is beast combine the displacement of the stock block with the DOHC OS Giken head and you have a motor that i dare say is better then the S20. im really torn between the 432 and the OS Giken head.
I know the engine is original, but it`s still a L engine no matter what it`s modification and thats a fact you can`t escape. My previous apartment host owns a S30Z 1970` with RB26DETT, having constant problems with drivetrain, if you are going to use a RB or JZ be prepared to pay atleast 2 grand usd for such an engine with all wiring looms, ecu, turbo`s, etc so my opinion is that the L series is the better engine for the Z`s :)
As much as I love this thing, they have some tuning issues to resolve, they have overchoked the carbs alot, 1:06-1:11 case and point. Get that right, and the torque band will be perfect.
@takulovesanime i totally agree l28 is beast and l28 + os giken head is god beast but the original 432 had an s20 and this s30 is def 432 inspired so an s20 is only natural but the S20 is the only motor for the hakosuka. also id rather have a kpcg then a s30 but thats just me.
thats because the e36's have a poor weight to power ratio. if he swaps a 2j, or an ls1 into it then it would be fast as shit. also the 325i has emissions restrictions that make it slow. the IS's models are a bit faster. but the only e36's that are worth hooking up is the m3's. preferably the obd1 models.
Yeah, he wants a M3 or M5 now, but I have a feeling he`d be satisfied if he but turbo`ed the one he already has. Just the insurance on a M3 or M5 is sky high here, he already pays about 1700 euros a year for his 325i.. That`s 2 mint ke70`s or 2 ae86 shell`s right there..
the head iz a really nice piece of work ,the revs are 2 sic for words the os with a stock z crank polished would work w/ add in race valves and guides / seals.., moderate cam ,the supa dampner , webers with some rock screen, the os head is,20 to 50 k but turns a z block into a six hyabusa racer i mean rica ahuh huh...... needs 2 oil pumps and a roller cam oooh 8 k rpm red line carbon drive and half shafts and some konis and this z woulld run with a vette sayanara sucas my 260 did 145 weekly 18 tickets in 3 months on pirrelies lowered stock
ok i know what the engine is, i am well familiar with the company. but the ORIGINAL engine was a L6 SOHC not an L6 DOHC. which means its not the original engine. now IF I was going to upgrade to a DOHC engine I rather use an RB,SR, or A 2JZ. more modern engines that have greater after market support and has a wide range of options for specs. the car is still awesome regardless, but i would have gone with a different setup.
Might be the best sounding 6 cylinder I've ever heard, and one of the best intake noises EVER!!!
OMG, I need that DOHC head. Never thought I'd see one in use for real. Fantastic. FYI, I used to own Datsun Z # 427 which was produced in December 1969. Shipped to the states in Jan 1970. That one and # 17122 from 1971. Such great cars.
Never get sick of listening to that noise.
Thank you for the response! I'm building an S30 right now & this wing'll be perfect!
For more Information about the history about this head and how Tomitaku got his hands on one, speedhunters did an article about it.
This is too all who have any questions about this car. This is Tomitaku's 240z, this is not a 240zg or a 432 fairlady z.

HOW COOL IS THE COROLLA BEHIND IT!!!!
Holy shit this is well on par to the old Alfa Romeos of Italy for sound! Incredable!
@br1anzkilLs no its not the whole drive train, you dont need a different transmission or block or diff or anything like that its just a bored out block with a different head....
Its a OS Giken optional twin cam head for the L series engines. Worth approx $10K if still available. Z432 had a S20 engine and badges to identify it. Thats one sweet Z!

right on man..........it's the nostalgia of it all in such a classic that you strive to hit. Nothing to do with $/performance what so ever at all.
Nostalgia + bragging rights..........what else could you ask for.
@idriveforeign No, L24 with OS giken head, only 9 exist. Z432 had a S20 which is a 2.0L inline 6 dohc. Mikuni solexs too not webers, Japanese version.
such cool vintage cars. seeing the Z and the corolla run down was very nostalgic. too bad the corolla fell off as the years passed on. very cool vid
OS Giken is going to make a few more of these heads this year. I couldn't find a price but I heard they are all spoken for.
one of the best S30Z's I've ever seen.....WOW!!!
@Euphorica And just think about it, this is the l24 the smallest of the 6cyl l series and it makes ~350hp. Thats mad nuts for these engines considering 300+ takes a serious proffesional to achieve in a L28 3.1 stroker.

And this Z seems to be a "remix" version of the almighty 432(-R), that borrowed the PRINCE R380's S20 mill.
To finish, I think OS Giken's purpose is : FUN. And for that, no (necessarily) need for performance. Just look at the drivers' faces and way of speaking once they get off the car !!!

Yeah, a friend of mine owns a BMW 325i 1997 mod with M3 suspension that he bought from a cousin, unfortunately he doesnt want to upgrade the engine, that thing would take out almost any car, but as it is now, he was even passed by a Golf ;)
It's actually just not the head. It's the whole drivetrain. You need it to run extra cam and gears. So it's also a block. That you need for the head.
Very nice, I like it. Done with a lot of taste. It dosent get any rareer then that. Beautiful car.
RB26 or SR20 on 280z is insane, you feel the power up instantly even with stock engines, and the no-traction feeling even when driving a straight line at 40 mph is actually kick ass :)
Is this car is still exist?? Does anyone know about the black corolla details?
Its sept 2018 why has nobody else produced a twin cam head for the l28. It sure would help save on engine swaps.....we have rapid prototyping now and 3D printing.
You could easily adapt a four cylinder design .
It could be a very affordable head.Why doesnt Giken produce them why only 9 .I heard they built another run , but surely it can be mass produced on a limited run to have more enthusiasts glorifing this great concept. I dont like engine swaps but a HEAD swap is a beautiful thing.
There have been a few people that cut up a couple of ka24de heads and welded them together to make a twincam I6 head for the l28.
@PirateKing666 screw the S20, go OS giken. Picture a kameari 3.1L L28DTT with triple mikuni's. If your looking at build ability L28 any day. Until the late 80's the L28 was the most build able engine in japan since the early 70s. if your looking at nostalgia S20 is cool, but IMO i feel its more of a hakosuka motor and the sound of a stroker L28 is such god.
@SoberGargamel 44mm intake for each cylinder. Thats huge. i love that noise!
Exactly, might come from l28 (The guy might have done a swap.) I`ll add u as friend so we can continue the discussions elsewhere :)
Champagne, lol. Hes "christining" the motor. This cars a work of art.
Exactly, should be able to get around 90`ish more hp out of that 2.5 litre.
Today I saw a triple dellorto carburettor turbo setup for sale, it was listed for 240z 1970 model, so I`m not sure whether its for L28 (Although a big possibility, not sure.) Would be a cool thing to have for a one of a kind "RB30DE/NAT" as I call it, hehe.

that sound is beautiful
It's cold and has a carb setup, you can hear it doesn't rev up very smooth in the beginning of the vid. After that it runs fine :)
i think its a 432R, the engin is 6L 2liter dohc, it can put out 300hp n/a, realy fast
Man.. that is such an awesome Z.. I NEED one!
sounds like heaven...

that thing revs like a beast!!!
Yeah basically a RB30DET block and RB25 head :)
My economy is a bit weak at the time as well, so I decided to go for ae86 now, and get a 280zx later :)
when this beauty is revving nobody cares about the porsche 911, that is just awesome
that is something i would defiantly want to see.
Yes, easily, it's a big car inside
anybody know what wing is on this S30?
i dont know what ur talking about because i know 2ppl that have rb's swaps and never had problems with their drive-train. 1 was running a stock 280z lsd with an rb25 n the other was running a 300 lsd n never had a problem either. the 300 pumpkin needed some customization. btw the 300tt transmission bolts to the rb25. so if u have an rb26 u can just find a 300 tranny instead of buying an expensive rb tranny.
icefreet, the engine is L series, the head is custom made by OSgiken though :)

what it means this number plates with the red stripe by the Fairlady ?
@barthoedemaker for sure....even if i drive boosted cars, ive never been able to kick the addiction of a well rounded NA built car...too sexy.
this is the nices sound i have ever heard out of a Z.Look at the car nice color and great sound,.If you have ever ovwend a 240,260Z then you know how it feels ,to drive a great Car.

It was an original 432R??
What a car park..... datsun heaven! Love the s20 engine also, oh amd the in-car 510sss at the end!
Great vid, cheers mate! :)
the OS Giken head is beast combine the displacement of the stock block with the DOHC OS Giken head and you have a motor that i dare say is better then the S20. im really torn between the 432 and the OS Giken head.
the stock l24 240z engine had more torque then the stock s20 engine in the 432z.. only 10 hp less for the l24.
How's this OS Swap compared to the original S20 engine from Z432 / GT-R? What's the dyno numbers?
I know the engine is original, but it`s still a L engine no matter what it`s modification and thats a fact you can`t escape. My previous apartment host owns a S30Z 1970` with RB26DETT, having constant problems with drivetrain, if you are going to use a RB or JZ be prepared to pay atleast 2 grand usd for such an engine with all wiring looms, ecu, turbo`s, etc so my opinion is that the L series is the better engine for the Z`s :)
@SicCreations It literally is the best. Only 9 of those heads exist in the world.
is all about how much u wanna spend. if i had a 240z i would drop an sr, but if i had a 280z then i would go rb/jz.
As much as I love this thing, they have some tuning issues to resolve, they have overchoked the carbs alot, 1:06-1:11 case and point. Get that right, and the torque band will be perfect.

Does this car have a engine swap or this is the original motor with cams on it?
just need $50000 more and I will have this engine...... cries
I can build same engine without that head with same amount of power for $5,000 ,,,
@@3rd-eye-neenja563 cool any links to your $5000 engine?
That motor just pulls and pulls and pulls. I wish my L24 pulled that hard! haha
i am hopping that in a couple of years if the economy gets better, to do a 280z with a rb26 or an sr20.
thats because the e36's have a poor weight to power ratio. if he swaps a 2j, or an ls1 into it then it would be fast as shit. also the 325i has emissions restrictions that make it slow. the IS's models are a bit faster. but the only e36's that are worth hooking up is the m3's. preferably the obd1 models.

awesome car, awesome sound, thanks for this awesome video.
@vtecboi18 That's insanity, but then again, what isn't?
たまらんですなぁ～😊👍
That car is beautiful. I just got a 370Z, and I must say, I can see the resemblance. Z-cars for life baby!
Why is it smokin? loss compression?
Was that S30 NA? Because I love dem high-power turbos.
Does anyone think a set of those Rotta RB R wheals would look good on my S130 Fairlady Z?
Nice S30 & TE27!
mmmm nice! thatswhy I am putting a RB20 out of my ceff into my 260... but it will never sound like that :)
early on u c the S30Z and a 911 Porsche Turbo----Wangan Midnight!!!!
What an engine! NA is best.
the head iz a really nice piece of work ,the revs are 2 sic for words the os with a stock z crank polished would work w/ add in race valves and guides / seals.., moderate cam ,the supa dampner , webers with some rock screen, the os head is,20 to 50 k but turns a z block into a six hyabusa racer i mean rica ahuh huh...... needs 2 oil pumps and a roller cam oooh 8 k rpm red line carbon drive and half shafts and some konis and this z woulld run with a vette sayanara sucas my 260 did 145 weekly 18 tickets in 3 months on pirrelies lowered stock
Imagine all that, plus a turbo...
lol that dyno is awesome
when it's reving it kinda sounds like the BMW M3 GTR from NFS: Most Wanted
6 cyls, 5 stars, 4 valve, 3 webbers, 2 ohc and 1 hot peice of work!
FTW!
@grimheathen no they aren't
やっぱりＳ３０は最高だな。
I wold gladly pay $10, thousand for that head convertion!!!!!
This car is like the devil Z in the wangan.
@280z1 thats what she said...
yep
That head! D: *drool*
@Ryoukun16 lol i know right
such a fairlady :)
ok i know what the engine is, i am well familiar with the company. but the ORIGINAL engine was a L6 SOHC not an L6 DOHC. which means its not the original engine. now IF I was going to upgrade to a DOHC engine I rather use an RB,SR, or A 2JZ. more modern engines that have greater after market support and has a wide range of options for specs. the car is still awesome regardless, but i would have gone with a different setup.
i love how all da japanese cars have da mirrors on da hood.

@Marcmannugget The top of motorsport is NA !
0:31. BLACKBIRD!!!!!!!
WOW ! How do you know ?
Is it a orange version of the devil z???? xDDD
Count me in as owned, along with Need4car
